Summary: Long-term pesticide-driven selection pressure is a major cause of insect outbreaks. This study found that low doses of triflumezopyrim can increase the fecundity of white-backed planthoppers. By continuously screening generations with a low dose of triflumezopyrim, a triflumezopyrim-resistant strain was obtained. Further investigation revealed that the transcription factors USP and Kr-h1 play important roles in the reproductive development of the planthoppers and overexpression of these factors in the resistant strain may lead to reproductive outbreaks of pests.

Summary: This study investigates the sublethal effects of imidacloprid and sulfoxaflor on the feeding behavior of the brown planthopper (BPH) and white-backed planthopper (WBPH). The results show that these insecticides can inhibit the phloem feeding and decrease the reproduction longevity of the planthoppers. It is also found that the effectiveness of the insecticides varies between different insect pest species.

Summary: This study reveals that P450s, especially CYPSF01, play a key role in the resistance of S. furcifera to triflumezopyrim, and its overexpression is related to the overexpression of USP.

Summary: Clothianidin has sublethal effects on S. furcifera, adversely affecting survival and reproduction but promoting development. It increases P450 enzyme activity and expression of related genes, with CYP4CE3 and CYP6FJ3 playing important roles in detoxification and resistance evolution.

Summary: The sublethal effects of Cycloxaprid on the white-backed planthopper were investigated. It was found that Cycloxaprid decreased the longevity, fecundity, oviposition days, and egg hatchability of the pests. However, it had no significant effects on other reproductive and growth characteristics of the individuals. Furthermore, Cycloxaprid significantly induced the expression of certain P450 genes while decreasing the expression of vitellogenin gene in the pests.

Summary: By utilizing third-generation sequencing technologies and Hi-C data, we successfully generated a high-quality chromosome-level assembly and provided a large amount of transcriptome data for analysis. The results of this study demonstrate that the genome assembly of the white-backed planthopper is of high quality, including the identification of definite sex chromosomes and comprehensive transcriptome profiles. This will contribute to the application of the white-backed planthopper as an efficient research object for functional genomics.

Summary: The study found that the melon aphid developed resistance to acetamiprid, resulting in reduced fitness including adult longevity and fecundity. The Ace-R strain also showed shorter pre-adult and pre-oviposition periods, along with changes in gene expression associated with reproduction and development.

Summary: This study examined the oviposition preferences and development of the fall armyworm on different maize varieties. The results showed that the fall armyworm can oviposit and complete its life cycle across all maize cultivars, but females prefer special maize varieties for oviposition. The special maize varieties also promote faster growth, higher reproduction, and population parameters of the fall armyworm. These findings provide valuable information for population prediction and management, as well as refining laboratory rearing protocols.

Summary: Amblyseius orientalis, a predatory mite in China, plays a crucial role in agriculture and biological control. The study determined that the pollen + yeast + sucrose treatment was most favorable for captive breeding, providing a theoretical basis for indoor rearing and utilization of A. orientalis.

Summary: The study found that Spodoptera frugiperda could complete its life cycle on both maize and kidney bean, but with significant differences in development and reproduction. Although the pest can grow and reproduce on both hosts, it shows a preference for maize. High population density or scarcity of preferred hosts can make this pest harmful.

Summary: This study assessed the lethal effects and sublethal effects of the novel insecticides flonicamid and spirotetramat on different life stages of Bemisia tabaci. The results showed that spirotetramat was more effective against nymphs and pupae, while flonicamid was more effective against adults. Both insecticides had weak ovicidal potential. Spirotetramat showed higher toxicity than flonicamid for nymphs, but flonicamid was more toxic for adults. Both insecticides significantly reduced the population growth rate and reproductive parameters of B. tabaci.

Summary: The study found that graphene oxide (GO) had adverse effects on the development and reproduction of fall armyworms, including prolonged egg and larval stages, shortened adult lifespan, reduced fecundity, and altered gene expression related to reproduction. The use of GO as a pesticide additive may lead to a decline in population size.
