AB  - There are insufficient data about long-term (longer than six-months) residual effects of insecticides against Acanthoscelides obtectus (Say) as an important economic insect pest of stored bean. Therefore, we evaluated, in laboratory conditions, the insecticide potential of recommended rates of commercial formulations: organophosphate malathion (10 mg active ingredient - AI/kg), spinosyns bioinsecticide spinosad (1 mg AI/kg) and pyrethroid deltamethrins (0,25 mg AI/kg, with and without the synergist piperonil butoxide – PBO) after 210-, 265-, 310- and 365-days of post-treatment. Testing was performed on two types of beans with kidney- and cranberry-shaped kernels to evaluate the insecticide residual effects on the survival of weevils, progeny production, and related levels of kernels damage. Survival of weevils depends mainly on adults exposure/living period in treated beans and on the recovering period. Small differencies in weevils survival in each insecticide were recorded. We found increases in progeny and thus higher damage in beans, as manifested effects of sublethal doses only in malathion treated bean. In spinosad treated bean we recorded low levels of progeny and damage, below the economic threshold. In deltamethrin treatments, we recorded weevils avoiding contact with beans, no progeny and no damages. The effect of bean type was very low or non existent. It can be concluded that bioinsecticide spinosad can provide long-term protection of common beans against A. obtectus, while organophosphate malathion has low control potential. Pyrethroid deltamethrins residues cause adults to avoid treated beans and no offspring to appear. The obtained results might have significant impact on better understanding of weevils behaviour in the presence of insecticide residues and on the creation of sustainable pest management programmes.

Ispitivanja su realizovana prema OEPP/EPPO protokolima za testiranje kontaktne/rezidualne
aktivnosti insekticida. Imaga S. cerealella i S. zeamais su izlagana u kukuruzu tretiranom

Uticaj prašiva na redukciju potomstva je utvrđen posle sedam nedelja za S. cerealella i posle
osam nedelja za S. zeamais.
Posle sedam dana izlaganja, utvrđena je smrtnost svih izlaganih imaga (100%) S.

periodu najveća utvrđena smrtnost, 19%, izlaganih imaga S. zeamais je bila u kukuruzu
tretiranom sa 1,5 g/kg prašiva S1, dok je posle oporavka žižaka izlaganih ovoj količini
efikasnost bila 32%. Posle 14 dana sva prašiva su bila maksimalno efikasna za imaga S.

AB  - Zlatica krompira, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae) je
poznata kao destruktivna vrsta štetnih insekata, jer ako se blagovremeno ne preduzmu mere
suzbijanja može potpuno da uništi lisnu masu krompira. Specifičnost ove vrste je što su
podjednako štetni i imaga i larve, zbog čega se u usevima krompira svake sezone intenzivno
primenjuju insekticidi. Njihova efikasnost može da se razlikuje u zavisnosti od hemijske grupe
kojoj pripadaju i načina delovanja (prema IRAC MoA klasifikaciji), ali i zbog
osetljivosti/rezistentnosti populacija zlatice na različitim lokalitetima. Zato je cilj ovog rada
bio da se na lokalitetima Sefkerin, Belegiš i Glogonj ispita efikasnost različitih formulacija
preparata insekticida na bazi različitih aktivnih supstanci u zaštiti krompira od zlatice.
Ispitivanje je realizovano u skladu sa EPPO metodama za ocenu efikasnosti i obradu
dobijenih rezultata. Na sva tri lokaliteta su, uz utrošak vode od 4 l/100 m2, primenjeni
preparati na bazi: lambda-cihalotrina (IRAC 3A; formulacija CS) u količini od 1,0 ml
preparata/100 m2 površine useva, abamektina (IRAC 6; formulacija EC) u količini od 7,5
ml/100 m2, spinosada (IRAC 5; formulacija SC) u količini od 0,5 ml/100 m2 i
hlorantraniliprola (IRAC 28; formulacija SC) u količini od 0,6 ml/100 m2. Krompir namenjen
kontroli je tretiran vodom. Efikasnost u suzbijanju larvi L1-3 i L4 stupnja je ocenjivana posle 2-
3 i 7 dana od njihove primene.
Posle 2-3 dana od primene preparata, na svim lokalitetima, najefikasniji insekticid za
mlađe larve (L1-3 stupnja) bio je hlorantraniliprol, 98-100%, a najmanje efikasan lambdacihalotrin,
u rasponu od 66 do 72% u Sefkerinu i Belegišu, i 100% u Glogonju. Za starije larve
(L4 stupnja) su na svim lokalitetima najefikasniji bili hlorantraniliprol, spinosad i abamektin,
96-100%, a najmanje efikasan lambda-cihalotrin, 35% u Belegišu, 50% u Sefkerinu i 100% u
Glogonju. Posle sedam dana od primene preparata, za mlađe larve zlatice su na svim
lokalitetima najefikasniji insekticidi bili hlorantraniliprol, spinosad i abamektin, 97-100%, a
najslabiji lambda-cihalotrin, 71% u Sefkerinu i Belegišu i 88% u Glogonju. Za starije larve su
na svim lokalitetima najefikasniji bili hlorantraniliprol, spinosad i abamektin, 99-100%, dok je
najnižu efikasnost ispoljio lambda-cihalotrin, 0-20% u Sefkerinu i Belegišu, i 95% u Glogonju.
Dobijeni rezultati pokazuju visok potencijal preparata na bazi hlorantraniliprola,
spinosada i abamektina u zaštiti krompira od zlatice, dok je preparat na bazi lambdacihalotrina
ispoljio izraženo variranje efikasnosti.

AB  - Kontaktni (rezidualni) insekticidi osim što suzbijaju prisutne skladišne insekte
sprečavaju ili, u određenom periodu, smanjuju mogućnost ponovne infestacije uskladištenih
biljnih proizvoda. Štetni insekti tokom života dolaze u kontakt sa različitom količinom
depozita insekticida nanetih na proizvode ili skladišne površine, što može značajno da utiče
na njihovu efikasnost, kao i na ponašanje insekata. Namera u ovom radu je bila da se posle
primene na pšenicu u zrnu dve formulacije preparata na bazi deltametrina (EC, sa sinergistom
piperonil butoksidom i SC, bez sinergista) ispitaju efekti preporučene količine primene i
višestruko manjih količina na skladišnog tvrdokrilca Tribolium castaneum.
Istraživanja su prema EPPO metodama realizovana u laboratoriji na temperaturi od
25±1°C i 60±5% r.v.v. U prvom eksperimentu su obe formulacije deltametrina nanete na
pšenicu u zrnu, u šest ponavljanja, u količinama od: 0,025; 0,05; 0,1 i 0,25 mg a.s/kg. Insekti
starosti dve nedelje su izlagani tretiranoj pšenici dva, sedam, 14 i 21 dan, posle čega su
isejavani kako bi posle ukupno 10 nedelja mogao da se utvrdi uticaj na produkciju/redukciju
potomstva. U drugom eksperimentu su obe formulacije deltametrina nanete samo u količini
od 0,025 mg/kg, u osam ponavljanja. Ispitivani su efekti na imaga brašnara starosti dve i 24
nedelje, posle tri i 14 dana izlaganja u tretiranoj pšenici, i sedam dana oporavka u brašnu.
Ocena uticaja na produkciju/redukciju potomstva je utvrđena u brašnu posle ukupno osam
nedelja.
U prvom eksperimentu, posle dva i sedam dana izlaganja brašnara, nije zabeležena
smrtnost veća od 5%. Posle 14 dana izlaganja su obe formulacije deltametrina, primenje u
količini 0,25 mg/kg, bile 100% efikasne, dok je posle 21 dan izlaganja visoka efikasnost, 97-
99%, utvrđena i u pšenici tretiranoj sa 0,1 mg/kg. Takođe, utvrđeno je da je formulacija
deltametrina bez sinergista, posle 14 dana izlaganja brašnara količinama 0,05 i 0,025 mg/kg

Redukcija potomstva od 100% nije zabeležena samo kod količine primene od 0,025 mg/kg,

U drugom eksperimentu je najveća smrtnost brašnara utvrđena posle 14 dana
kontakta sa 0,025 mg/kg deltametrina bez sinergista, 27% kod mlađih imaga i 69% kod
starijih, dok je kod deltametrina sa sinergistom značajnija smrtnost utvrđena samo kod
starijih imaga, 21%. Redukcija potomstva je, kod obe formulacije deltametrina, zabeležena kod mlađih imaga posle tri dana izlaganja, 12%, i kod starijih posle 14 dana, 9-57%, dok je
stimulacija potomstva zabeležena kod starijih imaga posle tri dana izlaganja, 2-6%, i kod
mlađih imaga posle 14 dana izlaganja, 3-17%.

abstract = "Kontaktni (rezidualni) insekticidi osim što suzbijaju prisutne skladišne insekte
sprečavaju ili, u određenom periodu, smanjuju mogućnost ponovne infestacije uskladištenih
biljnih proizvoda. Štetni insekti tokom života dolaze u kontakt sa različitom količinom
depozita insekticida nanetih na proizvode ili skladišne površine, što može značajno da utiče
na njihovu efikasnost, kao i na ponašanje insekata. Namera u ovom radu je bila da se posle
primene na pšenicu u zrnu dve formulacije preparata na bazi deltametrina (EC, sa sinergistom
piperonil butoksidom i SC, bez sinergista) ispitaju efekti preporučene količine primene i
višestruko manjih količina na skladišnog tvrdokrilca Tribolium castaneum.
Istraživanja su prema EPPO metodama realizovana u laboratoriji na temperaturi od
25±1°C i 60±5% r.v.v. U prvom eksperimentu su obe formulacije deltametrina nanete na
pšenicu u zrnu, u šest ponavljanja, u količinama od: 0,025; 0,05; 0,1 i 0,25 mg a.s/kg. Insekti
starosti dve nedelje su izlagani tretiranoj pšenici dva, sedam, 14 i 21 dan, posle čega su
isejavani kako bi posle ukupno 10 nedelja mogao da se utvrdi uticaj na produkciju/redukciju
potomstva. U drugom eksperimentu su obe formulacije deltametrina nanete samo u količini
od 0,025 mg/kg, u osam ponavljanja. Ispitivani su efekti na imaga brašnara starosti dve i 24
nedelje, posle tri i 14 dana izlaganja u tretiranoj pšenici, i sedam dana oporavka u brašnu.
Ocena uticaja na produkciju/redukciju potomstva je utvrđena u brašnu posle ukupno osam
nedelja.
U prvom eksperimentu, posle dva i sedam dana izlaganja brašnara, nije zabeležena
smrtnost veća od 5%. Posle 14 dana izlaganja su obe formulacije deltametrina, primenje u
količini 0,25 mg/kg, bile 100% efikasne, dok je posle 21 dan izlaganja visoka efikasnost, 97-
99%, utvrđena i u pšenici tretiranoj sa 0,1 mg/kg. Takođe, utvrđeno je da je formulacija
deltametrina bez sinergista, posle 14 dana izlaganja brašnara količinama 0,05 i 0,025 mg/kg
bila 2,5 i 27 puta efikasnija od formulacije sa sinergistom, a posle 21 dan dva i sedam puta.
Redukcija potomstva od 100% nije zabeležena samo kod količine primene od 0,025 mg/kg,
koja je kod deltametrina bez sinergista bila 99,4%, a kod deltametrina sa sinergistom 93,8%.

AB  - We studied the insecticidal effects of ashes from three different tree species (common beech, Norway spruce, and black locust) on the mortality of Sitophilus zeamais adults under laboratory conditions. A diatomaceous earth formulation, SilicoSec® was used as a positive control. We studied the contact effects of ashes on adults and the insecticidal effect of ash mixed with wheat grain. The experiment was carried out at three different temperatures (15, 20 and 25 °C) and at two different relative humidity [r.h.] values (55% and 75%). The study on contact effects (immediate mortality and delayed mortality) was carried out in Petri dishes, where we applied ash in two concentrations, 10 and 20 g/m2. After 7 d there was more than 97% mortality for the beetles in all three wood ashes at 25 °C and 55% R.h., while after 14 d wood ash of Norway spruce showed the highest effectiveness (87%) at 20 °C and 55% R.h. 96% mortality was recorded at 20 °C and 55%, when SilicoSec® was applied. The experiment with the mixture of ashes and grains was performed by mixing 2.5 or 5 w% of ash with wheat. In both approaches, we established that lower R.h. in combination with higher temperatures led to higher adult mortality rates. Regardless of the approach, the preparation concentrations did not influence adult mortality. The most efficient ash was that of Norway spruce, yet we attribute its effectiveness not only to its highest content of SiO2 (11.68%) but also to the other ingredients in ash, which can enhance its hygroscopic properties. Our research demonstrated that wood ash can efficiently protect stored crops from maize weevils. However, before introducing wood ash into the systems of protecting stored wheat grains against harmful insects, the influence of concentrations of ashes and their hygroscopic properties should be studied.

AB  - This study aimed to evaluate insecticidal activity of three diatomaceous earths DEs, two originated from Serbia (DE S-1 and DE S-2) and one commercial formulation (Protect-It, Hedley Technologies Ltd. Canada) applied at rates of 0.5, 1.0 and 1.5 g/kg (500, 1000 and 1500 ppm) on Rhyzopertha dominica in wheat, barley, rye, oats and triticale grains and their effects on mass of kernels and several properties: adherence, hectolitre mass, moisture, protein and ash contents. Mortality of R. dominica adults increased with exposure duration and DEs rates. In all tested grains after the longest exposure period (21 days), 1.0 and 1.5 g/kg rates of Protect-It, and 1.5 g/kg rate of DE S-1 and DE S-2 (in barley) caused 95–100% mortality. Offspring reduction of ≥95% was recorded after the application of 1.0 and 1.5 g/kg of Protect-It and 1.5 g/kg of DE S-1. The lowest weight of damaged grain was found after applying 1.0 and 1.5 g/kg of DEs to all grain types, and the highest in rye and wheat treated with 0.5 g/kg DE S-1 and DE S-2, respectively. The highest DEs adherence of 83–95% was detected in wheat, and 87–92% in oats, and the lowest of 71–77% in rye and 59–73% in triticale. All DEs significantly reduced hectolitre mass of all grains, especially Protect-It, 3.6–8.8%. No negative effects of DEs were detected on moisture contents, and the contents of proteins and ashes in the grains. The changes were due to the activity of R. dominica.

AB  - The effects of the insecticides deltamethrin, bifenthrin, thiamethoxam, spinosad and abamectin were tested in the laboratory in combination with extreme temperature of 50 °C to discover potential improvements of existing pest management programmes for Sitophilus oryzae (L.) control. Adults were released into wheat grain treated with three insecticide doses ranging 0.125–1.0 mg/kg and exposed to 50±1 °C temperature at the intervals of 0, 65, 75 and 85 min, and direct and combined effects were determined after 1, 2, 7 and 14 days of exposure/recovery at 25±1 °C and 60 ± 5% r. h., as well as impact on F1 progeny production/reduction PR (%) after 8 weeks.
The results showed that the mortality of S. oryzae adults increased with exposure/recovery duration more than under the activity of each insecticide alone and its interaction with extreme temperature. After 14 days, all three rates of deltamethrin (0.125–0.5 mg/kg), the two higher rates of bifenthrin (0.25 and 0.5 mg/kg) and the highest rates of abamectin (0.5 mg/kg) and thiamethoxam (1.0 mg/kg) caused maximum adult mortality (100%) and PR (100%) after weevil exposure to 50 °C already after the interval of 65 min, while spinosad had the same effect after 75 and 85 min, which effectiveness was 1.25–20 times higher than the activities of the insecticides and 50 °C temperature alone, considering all trial variants. The lowest rate of bifenthrin (0.125 mg/kg) was found after 65 min activity in combination with exposure to 50 °C, and especially spinosad (0.25 mg/kg) after 65 and 75 min, to have stimulated progeny production 17, 33 and 236%, respectively, while deltametrin showed 100% effectiveness against S. oryzae in all combinations of wheat grain treatment at 50 °C temperature, including the dose 0.125 mg/kg.

Adults were released into wheat grain treated with three insecticide doses ranging 0.125–1.0 mg/kg and exposed to 50±1 °C temperature at the intervals of 0, 65, 75 and 85 min, and direct and combined effects were determined after 1, 2, 7 and 14 days of exposure/recovery at 25±1 °C and 60 ± 5% r. h., as well as impact on F1 progeny production/reduction PR (%) after 8 weeks.
The results showed that the mortality of S. oryzae adults increased with exposure/recovery duration more than under the activity of each insecticide alone and its interaction with extreme temperature. After 14 days, all three rates of deltamethrin (0.125–0.5 mg/kg), the two higher rates of bifenthrin (0.25 and 0.5 mg/kg) and the highest rates of abamectin (0.5 mg/kg) and thiamethoxam (1.0 mg/kg) caused maximum adult mortality (100%) and PR (100%) after weevil exposure to 50 °C already after the interval of 65 min, while spinosad had the same effect after 75 and 85 min, which effectiveness was 1.25–20 times higher than the activities of the insecticides and 50 °C temperature alone, considering all trial variants. The lowest rate of bifenthrin (0.125 mg/kg) was found after 65 min activity in combination with exposure to 50 °C, and especially spinosad (0.25 mg/kg) after 65 and 75 min, to have stimulated progeny production 17, 33 and 236%, respectively, while deltametrin showed 100% effectiveness against S. oryzae in all combinations of wheat grain treatment at 50 °C temperature, including the dose 0.125 mg/kg.",

AB  - iColorado potato beetle (CPB, Leptinotarsa decemlineata Say) resistance is one of the limiting
factors in potato production in some regions of Serbia. Imidacloprid is first introduced neonicotinoid
insecticide in use for effective CPB control. Introduction of such insecticides with novel mode of action
and physicochemical properties, demands investigations on resistance risks and management tactics.
Primary candidates for cross resistance are insecticides acting on same target sites (such as bensultap,
with CPB resistance reported), although other cross resistance patterns between apparently unrelated
insecticides are not uncommon. Results of the investigations presented in this paper refers to the
resistance of CPB adults to 3 insecticides - imidacloprid, bensultap and cypermethrin, most commonly
used by farmers in recent years. First generation adults from nine field populations in first and four
representative populations in second year of investigation were tested by topical application.
Resistance ratios for bensultap ranged from 1.0 to 645.3 (LD50 from 0.04 – 25.81 μg/insect).
Cypermethrin resistance ratios ranged from 1.0 to 60.0 (LD50 from 0.02 – 2.05 μg/insect). Imidacloprid
resistance ratio was from 1.0 to 82.9 (LD50 from 0.0039 – 0.0323 ng/insect). Based on our results there
was no correlation between resistance levels for bensultap and imidacloprid. Although LD50 values for
imidacloprid were very low, significant resistance ratios obtained in these investigations, together with
threads of cross-resistance and importance of conserving field efficacy of neonicotinoids, strongly
recommands systematic resistance monitoring as important resistance management tool.

AB  - The aim of study was to investigate the influence of naturally occurring zeolite and diatomaceous earth, as inert dusts approved for insect pest control in certified organic crop production, on trading and breadmaking quality of treated wheat. The treatments significantly reduced the trading quality of wheat which was reflected through lowering of test weight. This effect was more marked in the case of low-vitreous wheat rather than in high-vitreous one. Investigation of rheological properties of flours made from the treated wheat demonstrated that treatments with natural zeolite and diatomaceous earth at all applied doses significantly increased the water absorption, which consequently increased the bread yield. However, these changes in the flour properties were not high enough to modify the quality attributes of bread as was shown by instrumentally measuring crumb hardness and springiness as well as sensory evaluation.

AB  - The effects of prior contact of granary weevil (Sitophilus granarius L.) parents from a laboratory population, a Belgrade Port population (selected with LD70 pirimiphos-methyl) and a Bijeljina population (selected with LD70 deltamethrin) with filter paper treated with sublethal doses (LD20 and LD50) of the insecticides dichlorvos, malathion, chlorpyrifos-methyl, pirimiphos-methyl and deltamethrin on offspring production of the surviving insects in F1 generation (after 10 weeks) and F2 generation (after 16 weeks) in untreated wheat grain was examined under laboratory conditions. Offspring reduction of laboratory weevils was highest at 96% in the F1 generation after parents' contact with LD50 dichlorvos, and lowest in F2 generation after contact with LD50 pirimiphos-methyl with 84% more insects than in the control. The highest offspring reduction of selected weevils from Belgrade Port, 83%, was recorded in F1 generation after treatment with LD50 dichlorvos and chlopyrifos-methyl, and the lowest in F1 and F2 generations after contact with LD50 pirimiphos-methyl, around 44%. The highest offspring reduction of the selected weevils from Bijeljina, 100%, was found in F1 and F2 generations after contact with LD50 dichlorvos, malathion and deltamethrin, and the lowest again in F1 and F2 generations after contact with LD20 chlorpyrifos-methyl, in which case insect numbers were some 130% higher than in the control. The results indicate that sublethal insecticide doses, apart from a significant decrease in their efficacy against treated granary weevil populations, may also provoke an increase in insect numbers in the following generations.
