Summary: The demand for eco-friendly natural insecticides is increasing as awareness of the hazards of synthetic insecticides grows. A study found that the abundance of larvae from the pest Spodoptera litura Fabricius, which is resistant to multiple insecticides, varied among five varieties of eggplant. The researchers discovered that the differential abundance may be caused by the varying levels of steroidal alkaloids in the eggplant varieties. The presence of solasonine, a type of steroidal alkaloid, in high amounts deterred larvae and reduced their growth rate and efficiency in converting food into body substance. The foliar application of solasonine on the eggplant varieties also proved to be effective in deterring larvae. Introducing this botanical insecticide into eggplant pest management could be a beneficial alternative to synthetic insecticides.

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: This study investigated the insecticidal potential of chrysoeriol isolated from Melientha suavis against Spodoptera litura. The results showed that chrysoeriol was highly toxic to S. litura and significantly reduced the activities of detoxification-related enzymes and neurological enzymes. Chrysoeriol could be a potential agent for controlling S. litura.

Summary: This study aimed to identify novel bacterial strains effective in controlling Spodoptera exigua Hubner, Helicoverpa armigera Hubner, and Spodoptera litura Fabricius. Fifteen culturable bacterial strains were isolated from 60 dead larvae collected in the field. The results showed that 12 strains belonged to Bacillus thuringiensis kurstaki with high toxicity, and one strain was Lysinibacillus sp. with good toxicity potential. These strains are expected to play an important role in the development of biological pesticides.

Summary: This study identified and analyzed 19 nuclear receptors (NRs) in the genome of Spodoptera litura larvae, and found that the transcriptional levels of most NRs were significantly induced in the midgut after exposure to flavone and xanthotoxin. Knockdown of four NRs (FTZ-F1, EcR, Dsf, and HR3) resulted in reduced larval tolerance to the phytochemicals. Additionally, many detoxification genes were downregulated by dsNR administrations, which may explain the high sensitivity of S. litura to phytochemicals. Molecular docking revealed that phytochemicals had high affinity to bind to NRs. This study provides insights into the mechanism of host adaptation in S. litura and supports the development of NR-targeted insecticides.

Summary: Botanical insecticides offer a safer alternative to synthetic insecticides for insect control. The study revealed that extracts of Alpinia galanga rhizomes and certain phenylpropanoids have insecticidal activity against Spodoptera litura Fab, with 1'S-1'-acetoxychavicol acetate being the most active compound.

Summary: Nicotine is a highly addictive alkaloid found in tobacco that causes addiction and makes tobacco a high-demand commercial product. The metabolites of nicotine, called TSNAs, are hazardous substances that form DNA adducts and can initiate the process of carcinogenesis. TSNAs are used as biomarkers to assess cancer risk in humans exposed to tobacco. In this study, the presence of TSNAs in tobacco-feeding insects was analyzed using LC-MS/MS, and their potential detoxifying pathways were investigated.

Summary: Insects can accurately respond to environmental chemical signals through chemosensory proteins (CSPs). The crystal structure of CSP8 protein from the tobacco cutworm was studied, providing insights into the molecular recognition mechanism of SlCSP8 and the CSP protein family. The research suggests that CSP8 is crucial for insects to identify certain compounds, which may have implications for future CSP-based drug design.
