AB  - Alfalfa (Medicago sativa L.) hosts several species of aphid, Acyrthosiphon pisum (Harris), Aphis craccivora Koch and Therioaphis trifolii (Monell). The preference of the aphids of alfalfa plants for dense assemblies or individual plants, as well as for healthy or infested plants, was investigated in the field as in the laboratory. Years of field research have revealed the specific preferences of all three species of aphid. A. pisum and T. trifolii are most commonly found in alfalfa crops, while A. craccivora is mostly found on alfalfa weeds. Also, a single species of aphid alone is usually present on a plant. In order to determine the reason for this clear preference and to establish whether at the very beginning, i.e. at the stage of choosing a host, aphid species distance themselves from each other, we tested the effect of the volatiles of healthy and infested plants on their attractiveness to aphids. A. craccivora is repelled by the volatiles of dense crops and plants previously infested with one of the other two species. A. pisum and T. trifolii choose a dense assembly of plants, repelled by the volatiles of plants previously infested with A. craccivora. A. pisum displays the weakest competitive traits, and A. craccivora the strongest. This research showed that competition between aphid species does not occur only when they find themselves on the same plant at the same time, fighting for resources, but also in the choice of plant, in order to avoid later competition.

AB  - Progeny numbers and life parameters of Tribolium castaneum reared on a range of different animal feeds which varied in their protein-carbohydrate ratios (corn starch; corn feed flour; wheat bran; soybean meal; corn gluten; soy protein concentrate and soy protein isolate), four initial (population) densities (1, 2, 5 and 10 insect pairs) were evaluated. Adult insects were kept for seven days on a range of different diets to feed and oviposit before they were removed. After removing the adults, the emerging progeny were examined. The study found T. castaneum offspring could not develop on a carbohydrate-rich diet (corn starch) and on protein-rich diets (corn gluten, soy protein concentrate and soy protein isolate). Soy isolate showed a high, possibly insecticidal effect on parents. The fastest total development (egg to adult) (23.25–23.88 days, depending on the initial density), the highest offspring number (111.63–324.13) and the highest offspring body mass (1.38–1.73 mg) were recorded in wheat bran, while the slowest egg to adult development (35.13–37.88 days), the lowest offspring number (25–29) and the lowest offspring mass (1.04–1.48 mg) were recorded in soybean meal. The higher initial densities caused the eclosion period to be prolonged, reductions in female productivity and in offspring body mass on all diets. Initial density interacted differently with diet type in terms of offspring number, so as the density rose, the number of offspring in wheat bran and corn feed flour increased, while in soybean meal it remained low at all initial densities. This research gives us a better insight into the development of T. castaneum in animal feed that can help us to improve existing pest management in a way of finding a better solution to store products based on their susceptibility to this storage pest.

AB  - The effects of brewer's yeast and wheat patent flour on Tribolium castaneum (Herbst) life parameters at different population densities (1, 2, 5 and 10 pairs) were examined. A standard diet (95% wheat flour + 5% brewer's yeast) was used as control. The effect was examined on the duration of egg, larval and pupal stages, total development cycle, first adult emergence, eclosion period, the total number of offspring, number of offspring per female and body weight of adult offspring. For each diet type and population density, adults were allowed to feed and oviposit for 7 days before removal from diets. A longer larval stage was recorded in brewer's yeast (between 23.88 and 26.25 days, depending on population density) and patent flour (17.63–23 days) compared to the standard diet (12.88 and 13.38 days). The longest eclosion period was recorded in patent flour (19–21.23 days), which was the only diet unaffected by population density. In the brewer's yeast and standard diet, the period of eclosion was prolonged with the increase in population density. The lowest number of progeny was recorded in patent flour (44.29–49.63 insects), followed by brewer's yeast (22.86–177 insects), while the highest number of progeny (107.25–313.38 insects) was recorded in the standard diet. Population density did not affect the total number of progeny in patent flour, which remained low at all densities, while in the brewer's yeast and standard diet the rise in population densities caused a rise in progeny numbers. The type of diet did not affect the body weight of adult progeny: the highest body mass of progeny was recorded at the lowest population density and the lowest mass at the highest. This study provides insight into poorly researched development cycle and reproductive strategies of T. castaneum on brewer's yeast and patent flour, which are important stored products.

AB  - BACKGROUND: Movement of the red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), in stored products
is mediated by food volatiles and other semiochemicals.
RESULTS: In two-way olfactometer assays, T. castaneum was more attracted to wheat bran previously infested with conspecifics
than to uninfested bran. Chemical analysis showed that 1-pentadecene was present in the headspace of T. castaneum-infested
wheat bran, but not detectable in the headspace of uninfested bran. An olfactometer was used to test the effect on T. castaneum
behaviour of 1-pentadecene, and of volatiles from wheat bran with and without 1-pentadecene. The lowest concentration of
1-pentadecene exhibited an attractive effect, compared to the control (n-hexane). Slightly higher concentrations showed a neutral
effect, while the highest concentrations repelled T. castaneum. Wheat bran with a low 1-pentadecene concentration was
more attractive than wheat bran alone, whereas higher concentrations of 1-pentadecene were repellent.
CONCLUSION: The results provide important information on intraspecific, semiochemical-mediated behaviour in T. castaneum,
which could potentially be used to develop new methods to monitor the flour beetles in stored products.

AB  - Tribolium castaneum is one of the most economically important insects that damages stored products. The effects of several infested or uninfested raw feed materials (wheat bran, coarse wheat meal, corn feed flour), feed products (compound feed for pigs and for laying hens) and flour mixed with brewer’s yeast on the food-searching behaviour of T. castaneum adults were studied in a total of 48 combinations. Preference and olfactometer tests revealed that all the tested uninfested and intraspecific infested substrates were significantly more attractive to T. castaneum than the control (represented by part of an arena or olfactometer arm without substrate). We determined that all infested substrates were 2–9 times more attractive than uninfested in the preference test, while in the olfactometer test, they were 3–8 times more attractive. In comparing the attractiveness of the infested and uninfested substrates, in both tests wheat bran was found to be the most attractive substrate to T. castaneum adults and coarse wheat meal the least. The results of the present study contribute to our knowledge of how raw feed materials and products influence the behaviour of T. castaneum and their susceptibility to infestation, and indicate the possible utilization of wheat bran in monitoring processes of T. castaneum in pest management programmes.

AB  - The presence of the invasive coccinellid Harmonia axyridis in aphid colonies on plants, as well as its co-occurrence with native coccinellid predators was studied in the period 2011-2020. Also, its occurrence on fruit plants and grapes was monitored at harvest time. Research was conducted on 41 locations in Serbia. The feeding of this invasive species was recorded on a total of 43 aphid taxa of 25 different genera. It was most frequently present on aphid colonies of the genera Aphis, Brachycaudus and Myzus. The presence of H. axyridis in aphid colonies was recorded on 58 cultivated plant species: 10 fruit, 7 field crop, 5 vegetable and 16 ornamental species, as well as 20 non-cultivated plants. Harmonia axyridis feeding was also observed on mature fruit plants of cultivated blueberries, nectarine and grapes in representative production areas in Serbia. Nine native coccinellid species were detected in this study: Adalia bipunctata, Adalia decempunctata, Coccinella septempunctata, Hippodamia sp., Hippodamia apicalis, Hippodamia variegata, Hippodamia tredecimpunctata, Hippodamia undecimnotata and Propylea quatuordecimpunctata. Populations of H. axyridis and native coccinellids co-occurred in aphid colonies on many plants, i.e. in 53.45% of all samples. The results inferred that H. axyridis as a predator of numerous aphids on many plants is a useful coccinellid species. However, it may also be considered as a potential pest in fruit and grape production, and a threat to native aphidophagous coccinellids.

AB  - Using a two-way olfactometer, the effects of the whole wheat grains and coarse wheat meal odors on the primary Sitophilus granarius (L.), S. oryzae (L.) and S. zeamais (Motch.) and secondary Tribolium castaneum (Herbst) and T. confusum (Du Val) stored-product pests behavior were examined. Whole wheat grains and coarse wheat meal were used in uninfested and infested form. Whole wheat grains were infested with S. oryzae adults and coarse wheat meal with T. castaneum adults. The odors of infested wheat grains depending on the insect species were 1.9 to 3 times more attractive than the uninfested wheat grains odors, except for the T. castaneum for whome the odors of infested and uninfested grains were equally attractive (p = 0.641). The greatest difference in the attractiveness of the infested and uninfested wheat grains odors was found for T. confusum (3 times longer in the arm with the odors of infested grain), and the smallest for S. granarius (1.9 times). We found that all primary and secondary stored-product pests, depending on the species, were 1.4 - 2.4 times more attracted to the odors of infested compared to the odors of uninfested wheat meal. The greatest difference in the atraction of infested and uninfested coarse wheat meal odors was recorded for the T. confusum, whose adults were 2.4 times longer in the arm with the odors of infested coarse wheat meal than in the arm with odors of uninfested wheat meal, while the smallest difference (1.4 times) was recorded for S. oryzae. The results of this study give a significant contribution to a better understanding of the storage insects behavior, which could be used in the design of new methods of monitoring of their presence in stored products.

AB  - The effects of population densities (10, 25, 50 and 100 adults/50 g) and three diet types (protein-rich, carbohydrates-rich and compound feed) on life parameters (first emergence, development rate, number of progeny and body weight) of T. castaneum progeny were assessed. For each diet type and population density unsexed adults were allowed to feed and oviposit for 7 days before removal. No progeny developed on protein-rich diets (sunflower meal, soybean concentrate, and corn gluten). In carbohydrates-rich diets (corn feed flour, wheat bran, coarse wheat) and compound feed for pigs and laying hens, first adults required the least time to emerge in wheat bran and control diet (wheat flour + 5% yeast) (15.2-16.5 days), and the longest in corn feed flour (23.1-24.5 days). In wheat bran and control diets, the adult emergence period was the shortest (15.7 and 15.2 days) at the initial population densities of 100 and 50 adults/50 g, and significantly longest (16.5 and 16 days) at the lowest density. Conversely, adults fed on feed for hens diet emerged the latest, after 22.5 days, at the population density of 100 adults/50 g, and the earliest, after 18.6 days, at 25 adults/50 g. The shortest period of adult emergence at all population densities was found in the control (15.9-20.2 days) and wheat bran (18 -29.7 days), and the longest in feed for hens (56.2 days) and pigs (59.5 days) at the highest population density. Considering all densities, number of progeny were the highest in control diet (498-1226 adults) and wheat bran (354-1344 adults), and lowest in coarse wheat (220-300 adults). With increasing population density, progeny body weight decreased, and the highest weight was found in control diet and wheat bran (1.7 and 1.6 mg) at the lowest population density, and the lowest weight (1.0 mg) in hen and pig feeds at the highest density.

AB  - Behavior bioassays were conducted in the laboratory (23 ± 1°C and 50 ± 5% r.h.) using the olfactometer to determine the effects of essential oils of three plant species in the Cymbopogon genus (Lemongrass), Cymbopogon nervatus, C. proximus and C. schoenanthus, on adults of Tribolium castaneum. The effect of essential oils was compared to a commercial biopesticide based on azadirachtin at three concentrations (0.0001, 0.001 and 0.01%). The results showed that all essential oils and the azadirachtin-based biopesticide had significant (p lt 0.05) repellent effects on T. castaneum adults at all tested concentrations, except C. proximus essential oil which showed a neutral effect at the lowest concentration. The highest concentrations of the essential oils of C. nervatus and C. proximus had significantly stronger repellent effects (p lt 0.05) than the lowest concentration. At the concentrations of 0.0001 and 0.001% all tested essential oils and azadirachtin showed a similar repellent effect without statistically significant difference, whereas the oil of C. nervatus had the highest repellent effect on adults of T. castaneum at the 0.01% concentration. Considering all tested variations, the essential oils of plants of the genus Cymbopogon showed similar or stronger repellent effects on T. castaneum adults than the biopesticide based on azadirachtin.
