Summary: The study discovered that topical application of the JH analogue methoprene induced the expression of GdMet in 3-day-old and 5-day-old adults of Galeruca daurica. Silencing GdMet through RNAi inhibited the expression of JHBP, JHE, Kr-h1, and Vg, while promoting FAS2 expression, leading to enhanced lipid accumulation and fat body development, ultimately inducing the adults into diapause ahead of schedule.

Summary: In this study, silencing of the VIH gene alone or in combination with the MIH gene successfully induced ovarian maturation and development in females of Macrobrachium rosenbergii, with more pronounced effects in mature individuals. Additionally, the dsRNA used to silence VIH also affected the expression of MIH, albeit with a delay compared to the dsRNA targeting both VIH and MIH simultaneously.

Summary: In this study, the roles of Methoprene-tolerant (Met) and Kruppel-homolog 1 (Kr-h1) in the reproduction of Liposcelis entomophila were investigated. Knockdown of Met and Kr-h1 resulted in decreased vitellogenesis and ovarian development, leading to a decline in fecundity. Moreover, the expression of other hormone factors, such as FoxO, was also affected. These findings highlight the importance of JH signaling in female reproduction of psocids and suggest that RNAi-mediated knockdown of Met or Kr-h1 could be a potential pest control strategy.

Summary: This study provides insights into the effects of Ovomermis sinensis parasitism on the development of Helicoverpa armigera. It was found that O. sinensis arrests the host development by reducing 20E and maintaining JH, thereby causing developmental arrests. Rescue experiments showed that injecting 20E can rescue midgut replacement issues in the host.

Summary: The study reveals the negative impact of juvenile hormone on the expression of immunity-related genes in female mosquitoes. It further demonstrates the important role of juvenile hormone in regulating mosquito immune responses. The findings suggest that juvenile hormone suppresses antimicrobial peptide gene expression through its receptor Met, while PGRP-LC activates this gene, indicating dual regulation by both the juvenile hormone and IMD signaling pathways.

Summary: Our study reveals that in the Asian lady beetle Harmonia axyridis, the absence of juvenile hormone (JH) triggers reproductive diapause, as indicated by JH measurements and the knockdown of the intracellular JH receptor methoprene-tolerant (Met). Furthermore, we demonstrate that JH biosynthesis, rather than the degradation pathway, determines the reduction of JH titer in diapausing females.

Summary: Insect development requires strict spatiotemporal gene expression, which is partially regulated by histone acetylation-deacetylation through histone acetyltransferases (HATs) and histone deacetylases (HDACs). This study investigates the role of histone deacetylase 3 (HDAC3) in Helicoverpa armigera (H. armigera) and its potential as a target for insecticides. The results show that HDAC3 knockdown leads to abnormal growth and development in H. armigera, including pupation disruption, abnormal wing development, reduced egg production, and hatching rate. The dysregulation of key hormone-related genes is implicated in the abnormal pupa development. The study also identifies differentially expressed genes and enriched signaling pathways following HDAC3 knockdown, suggesting the potential of HDAC3 as a target for combating H. armigera.

Summary: The study found that sublethal doses of MF have severe adverse effects on the development of Helicoverpa armigera, including ecdysis failure, prolonged larval duration, and decreased pupal weight. Additionally, MF inhibits ecdysteroidogenesis at sublethal doses, but induces the expression of 20-hydroxyecdysone (20E) response genes, including HaFTZ-F1.

Summary: This study utilized RNA-seq to analyze the transcriptome of non-diapause, summer diapause, and winter diapause groups, revealing differential gene expression profiles and pathways associated with summer and winter diapause. Identical pathways related to both seasons were identified, as well as key candidate genes for universal and differential functions in diapause preparation. Furthermore, genes involved in signaling and metabolic pathways were found to play key roles in integrating environmental signals for diapause preparation in both summer and winter.

Summary: The presence of semi-natural habitats in traditional and consolidated farming landscapes has a positive impact on pollinator diversity, with traditional farming landscapes supporting a higher diversity of pollinators due to their network of field margins. Land consolidation has equivalent effects on pollinator diversity as substantial decreases in semi-natural habitat in the wider landscape.

Summary: Traditional smallholding-dominated agricultural landscapes in Southern China are becoming more homogenized and consolidated, leading to large mono-cropped fields and depleted pollinator communities. Our study investigated the impact of farmland consolidation on wild bee communities and functional traits in oilseed rape fields in Jiangxi Province, China. We found that consolidation had an effect on intraspecific composition, particularly in abundant small-bodied species. Above-ground nesting bees may require specific management interventions to promote their persistence in consolidated agricultural landscapes.

Summary: Replacing pan traps with window traps in agricultural fields can improve sampling effectiveness for flower-visiting insects. Window traps captured more individuals and had higher species richness, with more similar species composition. However, caution should be exercised when using specimens from both traps as proxies for flower-visiting activity.

Summary: This study investigated the expression patterns of heat shock protein 70 (Hsp70) in Pieris melete during summer and winter diapause. The results showed that the expression of PmHsc70 and PmHsp70b were upregulated during both diapause periods. Heat shock induced significant upregulation of all three genes during diapause. None of the genes responded to cold or heat stress in non-diapause pupae. Furthermore, it was found that 39 degrees C for 30 min was the most sensitive heat stress condition for PmHsc70 expression in summer diapause, and the same condition was effective for the expression of all three genes in winter diapause. These results suggest that PmHsp70s play an important role in responding to temperature stress during both summer and winter diapause.

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: This study investigates the impact of landscape composition and diversity on the functional traits and body size of parasitoids, as well as their effectiveness in biological control. The results show that different species of parasitoids may respond differently to landscape features, with solitary parasitoids being more sensitive to habitat changes. These findings highlight the importance of considering landscape habitat changes in pest management strategies.

Summary: This study investigated the role of non-crop habitat in modulating the rice stem borer and parasitoid-mediated biological control. The study found that the rice stem borer infestation levels were highest in agriculture-dominated landscapes. The parasitism rate increased with pest pressure but was not related to landscape-level non-crop habitat cover. The landscape-level responses of parasitoids were species-specific and likely modulated by functional traits. More diverse landscapes experienced lower levels of rice stem borer infestation.
