Summary: This study investigated the overwintering strategies of the swallowtail butterfly and found that diapausing pupae deplete glycogen stores during the pre-diapause period and switch to using lipids during the diapause maintenance phase. They also accumulate trehalose as a cryoprotectant and reduce free water content to enhance cold tolerance.

Summary: In this study, the molecular mechanisms underlying the long-term evolutionary adaptation of the mountain butterfly Parnassius glacialis to different environmental conditions were investigated. Gene expression patterns related to diapause, hormone biosynthesis, energy metabolism, and immune defense were identified and found to be correlated with habitat-specific adaptability. Duplicated genes promoting plastic responses to diverse environmental conditions were also identified. These findings shed light on the successful colonization and diapause evolution of the mountain Parnassius butterfly species.

Summary: The Old-World bollworm, Helicoverpa armigera, showed higher viability on cotton, followed by other crops commonly cultivated in Brazil. Noncotton C(3)hosts were the major source of H. armigera moths in all regions, with C(4)hosts being important in regions where winter maize is cultivated. Regional differences in host use and population dynamics may be attributed to variation in alternative host utilization and the possible occurrence of facultative diapause and migration.

Summary: Plants produce defensive chemicals to protect themselves from insect herbivores, and these chemicals may also affect the microbial communities associated with plants and insects. This study investigates the impact of different milkweed species, which produce varying levels of toxic cardiac glycosides, on the diversity and composition of monarch butterfly and milkweed bacterial communities. The results show that each milkweed species has distinct microbial communities, but monarch feeding has little effect. Furthermore, host plant species may influence the microbiomes of monarch caterpillars.

Summary: This study investigates the correlation between host plant range and chemoreceptor gene repertoire sizes in Papilio butterflies. The results show that the breath of host plants does not appear to result in the obvious expansions of the odorant (ORs) and gustatory (GRs) receptors in Papilio butterflies. Additionally, candidate molecular targets associated with olfaction, oviposition, or reproduction in P. xuthus are identified.

Summary: Based on the experiments conducted, the diamondback moth, a major pest of cruciferous crops, does not show preference for the abaxial or adaxial leaf surfaces or for host plants based on their diet. However, larval preference is influenced by glucosinolate content, indicating that crops with higher glucosinolate content are more susceptible to damage by the diamondback moth. These findings are significant in the management of this pest.

Summary: The diapause induction of sugar beet moth is regulated by factors such as PER and TIM, and under low temperature and short-day conditions, the changes in their levels affect the PTTH and 20E levels in the brain and hemolymph, leading to the induction of diapause.

Summary: Geographical differences and synchronization of adult occurrence in the soybean pod borer Leguminivora glycinivorella were studied by examining the timing and intensity of winter diapause termination and summer diapause. Results showed that summer diapause intensity was influenced by photoperiodic transitions, with potentially bivoltine individuals having weaker or no summer diapause. Additionally, the summer diapause system may function to synchronize the emergence of males and females within the population.

Summary: This study investigated the chemical ecology and behavioral responses of the spruce budworm to pheromones and host plant volatiles. Using single sensillum recordings (SSR), the researchers identified the responses of olfactory receptor neurons in the antennal sensilla to these stimuli. The study found that male and female budworms showed higher sensitivity to specific chemicals. Overall, these findings contribute to the improvement of integrated pest management strategies for the spruce budworm.

Summary: This study investigated the effects of temperature and plant host on the development and population dynamics of the beet armyworm Spodoptera exigua. The findings showed that temperature and plant host significantly influenced the development time and spring emergence of S. exigua. The results of this study are important for predicting the population dynamics, occurrence, and management of S. exigua in crop fields.

Summary: This study revealed the diapause induction mechanism of Tetrastichus septentrionalis and found that it belongs to the long-day type with critical photoperiods for diapause induction. Diapausing larvae of T. septentrionalis were grey-brown, while normally developed individuals were light yellow. The study also calculated the lower developmental threshold and effective cumulative temperature for post-diapause development, and found that the supercooling point of diapausing mature larvae was significantly lower than non-diapausing ones.
