Abstract With further climate change still expected, it is predicted to increase the frequency with plants will be water stressed, which subsequently influences phytophagous insects, particularly Lepidoptera with limited mobility of larvae. Previous studies have indicated that oviposition preference and offspring performance of Lepidoptera insects are sensitive to drought separately. However, the integration of their two properties is not always seen. Here, we evaluated changes in oviposition selection and offspring fitness of a Lepidoptera insect under three water-stressed treatments using a model agroecosystem consisting of maize Zea mays, and Asian corn borer Ostrinia furnacalis. Results found that female O. furnacalis preferred to laying their eggs on well-watered maize, and then their offspring tended to survive better, attained bigger larvae mass, and developed more pupae and adults on the preferred maize. Oviposition selection of O. furnacalis positively correlated with height and leaf traits of maize, and offspring fitness positively related with water content and phytochemical traits of hosts. Overall, these results suggest that oviposition choice performed by O. furnacalis reflects the maximization of offspring fitness, supporting preference–performance hypothesis. This finding further highlights that the importance of simultaneous evaluation of performance and performance for water driving forces should be involved, in order to accurately predict population size of O. furnacalis under altered precipitation pattern.

Adult feeding preferences of Hylobius abietis on Picea abies, Larix decidua, Pinus sylvestris, Pseudotsuga menziesii, Abies alba and Betula pendula were tested in outdoor conditions. The preferred food source was P. menziesii, and the mean bark area consumed per seedling was 440.8 ± 147.9 mm2. The second most preferred host was P. abies. The coniferous species that suffered the least damage was A. alba (76.8 ± 62.56 mm2 per seedling). B. pendula was the least preferred source of food, and it caused mortality of 60% of weevils that fed on it. Weevils exhibited large differences in fecundity when fed with different tree species in a laboratory experiment. The largest number of eggs was laid by females fed with P. abies. Mean egg numbers reached 26.4 ± 24.89 eggs per experiment for P. abies. Similar fecundity was observed in weevils fed with twigs of P. sylvestris. Oviposition was approximately six times lower in females fed with L. decidua and P. menziesii. The maximum number of eggs laid by a single female during a one-month experiment was 90. The results are discussed in relation to management of H. abietis.

Objectives of this research were to evaluate the effect of larval experience on feeding preference of larvae and the effect of larval and pupal experience on oviposition preference of females in Musca domestica L. and Chrysomya megacephala F. Dietary experience from hatch to test significantly influenced feeding preference of the second-instar larvae in M. domestica (P < 0.01), but did not in C. megacephala. The larval dietary and pupal experience did not change the oviposition preference of C. megacephala, and experienced gravid females laid all of their eggs on pork muscle. Larval feeding regimen had no effect on oviposition preference of subsequent females in M. domestica. However, the pupal experience in M. domestica significantly influenced the oviposition preference of subsequent females, and M. domestica females from pupae matured on wheat bran laid significantly more eggs on wheat bran than those that matured on pork muscle, or filter paper whether pupae were washed or not (P < 0.01). These results demonstrated that host-selection behavior in M. domestica was shaped by preimaginal experience according to the chemical legacy hypothesis.

The aim of this study was to investigate the behavioral response of Bemisia tabaci towards Metarhizium anisopliae (isolates PR1 and GT3) volatiles. Behavioral response of B. tabaci was investigated based on adult feeding and oviposition preference in eggplant Solanum melongena L. The highest mean number of adult (87) and egg (418) of B. tabaci were observed in the control plant, while the lowest mean number of adult (26) and egg (107) of B. tabaci were deposited in the PR1-treated plant. There were 8 and 5 compounds identified from the isolates PR1 and GT3, respectively. The highest amount of compounds of 1-Hydroxy-2-aminopropane (61.96%) and 1, 4-Dioxane-2-ol (54.18%) were released by PR1 and GT3 respectively. The results obtained so far revealed that whitefly avoided the eggplants provided with cultures of the M. anisopliae isolates emanating the volatile organic compounds and suitability largely depended upon the volatile profile.

Abstract The influences of different plants on herbivores have recently attracted research interest; however, little is known regarding the effects of wild, local and cultivated varieties of the same plant from the same origin on herbivores. This study aimed to examine the effects of different tobacco varieties from the same origin on the oviposition preference and offspring performance of Spodoptera litura. We selected two wild (‘Bishan wild tobacco’ and ‘Badan wild tobacco’), two local (‘Liangqiao sun-cured tobacco’ and ‘Shuangguan sun-cured tobacco’) and two cultivated (‘Xiangyan No. 5’ and ‘Cunsanpi’) tobacco varieties from Hunan Province, China. We found that female S. litura varied in oviposition preferences across the tobacco varieties. They preferred to lay eggs on the cultivated varieties, followed by the local varieties, with the wild varieties being the least preferred. Furthermore, different tobacco varieties significantly influenced the life history parameters of S. litura. Survival rate, pupal weight, emergence rate and adult dry weight decreased in the following order: cultivated varieties > local varieties > wild varieties. Conversely, the pupal stage and development period decreased in the following order: wild varieties > local varieties > cultivated varieties. Therefore, we conclude that wild tobacco varieties have higher resistance to S. litura than cultivated and local varieties, reflecting the evolutionary advantages of wild tobacco varieties.
