Summary: Our study shows that while the mutations (LF)-F-1002 and (LF)-F-1002/D(941)G have significant impacts on the response to pyrethroids, the mutation D(941)G alone does not have a major effect compared to the wild type channel. This suggests that some mutations may not lead to resistance on their own but can enhance resistance when combined with other mutations.

Summary: Plant-derived volatiles play a significant role in the seasonal host selection and foraging behavior of the mirid bug, Apolygus lucorum. Higher levels of active volatiles are emitted by jujube and grape plants in September compared to August, while volatile emissions from cotton decrease in September, influencing the population densities of A. lucorum on different host plants.

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: The study investigated the developmental fitness of Peristenus spretus in response to different host stages. It was found that parasitizing 2nd-4th instar hosts resulted in the best overall performance for the parasitoid. The sex ratio of the offspring did not significantly differ among host instars, and the time required for parasitization depended on the host's body size.

Summary: This study investigated the behavioral responses of Apolygus lucorum and Peristenus spretus to cotton plants volatiles after different intensities of damage by the former. The findings suggest that damaged cotton plants emit herbivore-induced plant volatiles (HIPVs) which can be influenced by pest density and identified by P. spretus, providing insights into biological control against A. lucorum.

Summary: This study demonstrates the positive effects of buckwheat flowers on the lifespan and parasitic activity of Peristenus spretus, the dominant parasitoid of the mirid bug Apolygus lucorum. It identifies fructose as the most suitable sugar for P. spretus adults, with glucose also playing a significant role in extending female longevity and improving reproductive success. These findings offer insights for enhancing biological control of cotton pests by enhancing the nutritional resources available to parasitic wasps.

Summary: This study investigated the vital odor cues of two mirid bugs and evaluated the role of olfactory recognition in host recognition. The results showed that tetradecane was the most attractive attractant for the bugs, and it played a significant role in their olfactory selection of host plants. The study also found that host recognition is not entirely dependent on odor cues, and there are differences in host plant selection between the two pests at close range.

Summary: The study revealed that Apolygus lucorum exhibited significantly different trypsin-like enzyme activity and reproductive characteristics when feeding on different types of cotton. Hybrid cotton was found to be more effective in inhibiting the growth and development of A. lucorum. The total trypsin-like enzyme may serve as a potential target for controlling A. lucorum, especially the female adults.

Summary: This study reported on the life history and potential host plants of Helopeltis bakeri, a major insect pest of cacao in the Philippines. Observations in the laboratory and field surveys identified several potential host plants for H. bakeri, aiding in the development of pest management strategies. The information gathered helps in understanding the biology and behavior of this insect pest to control its population effectively in cacao-growing areas.

Summary: This study describes the recent discovery of the Mexican buckeye as a new host of the J. haematoloma bug, potentially leading to host race formation. Evidence of differentiation in mouth part length between host plant species indicates the possibility of host-associated adaptations in morphology and behavior. More research is needed to confirm the status of host race formation along the speciation continuum.

Summary: The cacao mirid bug, a major pest of cacao in the Philippines, can cause pod damage and abortion. No semiochemical-based system for monitoring and controlling this pest has been developed. In this study, a potential attractant was identified from host plants of the pest, and beta-caryophyllene was found to be present in all host plants. The results suggest that beta-caryophyllene has the potential to be used as an attractant in kairomone-based trapping systems as part of integrated pest management for cacao.

Summary: Elevated temperature directly affects the population dynamics of the crop pest Aphis gossypii. Transcriptomic analysis reveals that a moderate temperature increase of 3 degrees Celsius can induce gene expression changes that help A. gossypii adapt to warmer temperatures. Hsp70 and CathB genes play essential roles in the adaptation of A. gossypii to high temperatures.

Summary: Intraguild predation between natural enemies can affect population dynamics and biological control effectiveness. This study investigated the feeding choices of Hippodamia variegata towards cotton aphid mummies and found no obvious preference for live aphids or mummies. The results showed that Aphis gossypii was the main prey source and medium of consumption for H. variegata. These findings are important for evaluating the pest control ability of H. variegata and strengthening biological control strategies.

Summary: The widespread planting of transgenic Bt insect-resistant cotton has caused the non-target mirid bug Apolygus lucorum to become a major pest. The parasitoids Peristenus spretus and Peristenus relictus have the potential to control A. lucorum, but the insecticides imidacloprid and acetamiprid have negative effects on these parasitoids, especially P. spretus.

Summary: Previous studies have shown that matrine is highly toxic to Aphis gossypii Glover, a cotton aphid, and has low toxicity to its natural enemy, Hippodamia variegata Goeze, a lady beetle. In this study, the safety of matrine to H. variegata was evaluated through investigations on its contact and stomach toxicity, effects on life-table parameters, predatory ability, flight ability, and cross-generational effects. The results indicate that matrine has no significant negative effects on the reproductive capacity, longevity, or predatory capacity of H. variegata, and can be safely used in the local integrated pest management strategy for controlling A. gossipii.
