Summary: The study found that low concentrations of Cu2+ can increase the survival rate and reproductive ability of Spodoptera litura, leading to rapid population growth and potential outbreaks. However, high concentrations of Cu2+ have negative effects on the growth, development, and reproduction of S. litura, resulting in decreased adaptability.

Summary: This study found that fourth-instar Spodoptera litura larvae are attracted to cabbage laced with minor sex pheromones, and GOBP2 and OBP7 play a role in this attraction. These findings provide an important basis for exploring the olfactory mechanisms underlying sex pheromone attraction in moth larvae.

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: 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: In this study, the potential roles of the clock gene period (Per) in regulating sex pheromone communication in Spodoptera litura were investigated. The results showed that the expression levels of SlitPer and two desaturase genes differed significantly between the siPer group and the control group. The disruption of Per gene led to disordered sex pheromone titers and calling behavior in female S. litura, as well as decreased mating rates and reduced oviposition.

Summary: In this study, researchers identified genes related to sex pheromone biosynthesis in the Noctuid moths Spodoptera litura and Spodoptera exigua. They found that only the genes SlitDes5 and SexiDes5 were significantly overexpressed in the sex pheromone glands of these moths. Functional analysis of the SlitDes5 gene showed that its expression level could be reduced by 49.42% through RNA interference. These findings contribute to a better understanding of the key genes involved in sex pheromone biosynthesis and provide potential gene targets for pest control strategies.

Summary: In this study, three splicing variants of Sxl mRNA were identified in Spodoptera litura, and they highly expressed in the gonads, particularly in the testis. The Sex-lethal protein (SlSXL) is mainly distributed in the cytoplasm of spermatocytes and the head of spermatid. Knockout of SlSxl resulted in reduced sperm production and undeveloped testis, leading to decreased oviposition and hatch rate in the offsprings after mating with female.

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.

Summary: This study evaluated the morphology, flight ability, and life table parameters of T. remus reared on S. litura eggs for 30 generations, and found that it maintained stable parasitism performance and life table parameters on the target host S. frugiperda eggs. Therefore, the study concluded that S. litura eggs are suitable hosts for the mass-rearing of T. remus.

Summary: The study compared the life performance and mating choice of Spodoptera litura reared on different diets, showing significant effects on developmental stages, fecundity, and mate choice. Artificial diet may promote behavioral isolation, impacting mating outcomes. Host plant preference during the larval stage may shape phenotypic plasticity and behavioral isolation in S. litura populations.

Summary: The population parameters and feeding preference of Spodoptera litura on asparagus stems and leaves were studied. The results showed that S. litura could complete its growth and development on both stems and leaves, but stems were more suitable for its population growth. The third and fifth instar larvae preferred to feed on leaves, while other instar larvae did not show significant differences in feeding preference between stems and leaves.

Summary: The study conducted on the pest status of Erankliniella intonsa in important crops in Taiwan, and the predation rate of Orius strigicollis on it, revealed that releasing different stages of predators can affect pest control differently. The integration of life table and predation rate data is crucial for improving biological control programs.

Summary: The novel insecticide spirotetramat was found to have an impact on the egg hatch rate and life cycle of Frankliniella occidentalis, leading to suppressed population growth. Despite no significant differences in intrinsic rate of increase, the treatment group showed a lower population size compared to the control group based on population projection using basic life table data. This suggests that spirotetramat may be a suitable candidate for pest management programs.
