Summary: This study found that photoperiod and temperature are important environmental factors in inducing and terminating diapause in the migratory locust in temperate regions. The most effective conditions for diapause induction were found to be rearing adults under a short photoperiod and treating eggs at a low temperature, while the most effective condition for diapause termination was found to be treating eggs at 13 degrees Celsius for 20 days near the developmental threshold temperature of 15 degrees Celsius.

Summary: This study investigates the evolution of Galerucella calmariensis L. populations in response to new environments, showing that diapause timing varies under different photoperiods while development time remains consistent. This indicates rapid evolution of adaptative responses in introduced predatory insects.

Summary: Geographical variations in the photoperiodic response of larvae of Epicauta gorhami were examined in this study, indicating that diapause is induced earlier in higher latitudinal areas. This variation suggests different life history strategies for populations at different latitudes.

Summary: This study investigated the combined effects of photoperiod and temperature on diapause induction in the green mirid bug in northern China, establishing a model to predict diapause incidence. The model was found to accurately predict diapause incidence in this pest species, suggesting it can be incorporated into population dynamic models for pest management.

Summary: Geographical variation in voltinism, the number of generations produced per year, has been observed in many insect species. This study used population genomics to compare nine Scandinavian populations of the butterfly Pararge aegeria with different life cycle traits along both north-south and east-west clines. The results identified candidate genes related to the insect circadian clock, including a novel gene deletion in a single population. This research adds to the understanding of circadian gene variation as a potential mechanism for generating local adaptation of life cycles.

Summary: A study has revealed that a historically univoltine population of Ostrinia furnacalis has shifted its diapause strategy from univoltinism to bivoltinism due to the compensatory effect of elevated temperature in warmer climates. This evolutionary shift has led to more severe damage caused by O. furnacalis. Accurate prediction of phenology and population dynamics of this insect species requires considering both diapause proportions and temperature.

Summary: Brown marmorated stink bug, Halyomorpha halys, was studied in mountain and plains regions, showing univoltine and bivoltine life cycles, respectively. Poor establishment of the bug in plains was attributed to heat stress and oviposition issues. A model was developed to understand the relationship between cumulative degree-days and oviposition and adult eclosion.

Summary: The study utilized RNA interference to target juvenile hormone (JH) biosynthetic genes and identified that several genes in Colaphellus bowringi are significantly downregulated during reproductive diapause. Knockdown of certain genes induced diapause-associated traits, which could be reversed with a JH receptor agonist methoprene. This work provides evidence for the physiological roles of JH biosynthetic genes in reproductive diapause.

Summary: The Asian corn borer (ACB) is a devastating pest in China, with the ability to have one to seven generations each year depending on the climate. Previous investigations have found that ACB in northeast China exhibits both uni- and multivoltine patterns. Through experiments, researchers have successfully isolated strains of ACB with uni-voltinism, multi-voltinism, and no diapause. This study suggests that ACB has evolved intra-population variation in voltinism.

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 found that Aedes albopictus mosquitoes in Beijing are highly susceptible to Zika virus and can pass viable virus to their offspring through vertical transmission. The impact of diapause on regulating viral replication and survival was also examined. Infected mosquitoes had a significantly lower hatching rate, indicating an intriguing interaction between diapause eggs and the virus. These findings suggest that vertical transmission of Zika virus from diapause eggs may play a critical role in the dissemination and maintenance of the virus in the vector.

Summary: The study revealed that in Xiangshan Bay, C. abdominalis mainly sustains its population through egg production, with temperature being a key environmental factor influencing its reproductive strategy. Photoperiod may act as a seasonal signal for the copepod to produce diapause eggs in late spring.

Summary: The study found that releasing 3 to 4 insidious flower bug adults is most effective in managing populations of western flower thrips, and that spinosad can be used together with the insidious flower bug. Furthermore, the predation of insidious flower bugs on western flower thrips is not affected by day lengths, allowing greenhouse producers to release the bugs throughout the growing season.

Summary: The life cycle of the cabbage beetle in southeastern China is complex due to multiple options for adult development. This study provides detailed information on the multi-year emergence patterns of diapausing individuals and explores the influence of temperature and photoperiod on diapause duration. The findings suggest that the cabbage beetle adopts a multi-year dormancy strategy to survive local environmental conditions and unpredictable risks.

Summary: Research showed the potential transfer of resistance to the leafminer from resistant species C. reticulatum to susceptible species C. arietinum through interspecific crosses, estimated the inheritance pattern of resistance, and studied organic acid contents as selection criteria. Results indicated that high levels of succinic acid could potentially serve as a biochemical selection criterion for resistance to the leafminer.
