Summary: D. tryoni males remained near the release site after emergence, with the ability to inseminate the highest number of females on the second day after eclosion. Female receptivity decreased after oviposition experience, while multiple mating increased female offspring percentage.

Summary: Infection of Wolbachia in intestinal tissues of Habrobracon hebetor has been discovered. A method to completely eradicate Wolbachia in the parasitoid has been developed, and the effects of the endosymbiont on the host's digestive metabolism and enzyme activity have been examined.

Summary: The study found that cold storage can extend the shelf life of P. incisi, and storing late-age pupae at 13 degrees C for 10 or 15 days has no negative impact on the emergence and adult quality of P. incisi.

Summary: The study focused on the biological parameters of Microplitis manilae, a dominant larval parasitoid of Spodoptera frugiperda, and found that pupal cold storage significantly affected the emergence rate, parasitism rate, and longevity of wasp adults. The optimal storage condition was middle-aged pupae stored at 10 degrees C for 5-10 days. These results provide insights into mass-rearing of M. manilae for biological control against S. frugiperda.

Summary: This study evaluated the effects of imidaclothiz insecticide on the biology, transcriptome, and microbiome of Binodoxys communis, a parasitic natural enemy of aphids. The findings showed that imidaclothiz had deleterious effects on the survival rate, parasitic rate, and survival time of B. communis, with trans-generational negative effects. Transcriptome analysis revealed alterations in the expression of genes associated with energy and detoxification metabolism, while 16S rRNA analysis showed an increase in the relative abundance of detoxification-related bacteria. This study provides important evidence for the risk assessment of imidaclothiz and supports integrated pest management.

Summary: In this study, the selectivity of different insecticides for the pupal parasitoid of soybean caterpillars, Trichospilus diatraeae, was evaluated. The insecticides acephate, azadirachtin, Bacillus thuringiensis (Bt), deltamethrin, lufenuron, teflubenzuron, and thiamethoxam + lambda-cyhalothrin were tested. It was found that azadirachtin, Bt, lufenuron, and teflubenzuron did not affect the survival of T. diatraeae, while deltamethrin and thiamethoxam + lambda-cyhalothrin showed low toxicity and acephate was highly toxic.

Summary: The study found that the density of Diachasmimorpha longicaudata females foraging on a patch is negatively correlated with the number of hosts attacked by one female. In mass-rearing conditions, reducing the density of females per cage can decrease superparasitism levels without affecting adult emergence and female proportion.

Summary: M. mediator prefers A. segetum-infested cotton plants over healthy plants, with the infested plants emitting significantly higher levels of compounds compared to healthy ones. These compounds play a crucial role in modulating the interactions between the pest herbivore and parasitoid, influencing parasitoid behavior. Enhancing biological control of A. segetum by M. mediator through the application of HIPVs may be possible.

Summary: Meteorus pulchricornis is a parasitic wasp that preys on various lepidopteran pests. The use of broad-spectrum insecticides poses a serious threat to the olfactory recognition of nontarget insects like parasitoid wasps. In this study, the researchers discovered that the MpulOBP6 protein exhibited strong binding affinity to three insecticides, and the hydrophobic interaction was the primary driving force in the formation and stabilization of MpulOBP6-insecticide complexes. The findings have significant implications for understanding the impact of insecticide use on the olfactory recognition of nontarget insects in agricultural production.

Summary: Seven commonly used pesticides were tested for their toxicity effects on the parasitoid Aphidius gifuensis, with thiamethoxam and dinotefuran showing the highest toxicity. The study also found that certain pesticides had a greater impact on the survival and parasitism of adults at different time points. Additionally, the egg and larval stages of the parasitoid were more susceptible to pesticides compared to the pupal stage.
