Article Abstract
The invasion of the fall armyworm poses substantial threats to local agricultural safety, including the sugarcane industry. Exploring the insect-resistance mechanism is crucial for breeding resistant varieties. This study selected three representative materials from the genus─ L. (Badila), . hybrid (GT58), and (SES208), to investigate feeding preferences and developmental fitness of . Larvae exhibited a strong preference and highest fitness parameters in Badila leaves compared to SES208. Additionally, proteomic analyses of larval saliva from insects feeding on Badila and SES208 were carried out to test the types and abundance of proteins on different hosts. Furthermore, we identified fatty acid-binding protein 1-like activates plant defense responses, while aldehyde dehydrogenase negatively suppressed plant defense response. Our findings suggest that the plasticity of salivary proteins induced by different host plants, and also offer new insights into the molecular interactions between and plants.

Jinggangmycin-induced NlPR-L and NlABD4-L genes regulate fecundity in the brown planthopper, Nilaparvata lugens (Stål) (Hemiptera: Delphacidae).

The brown planthopper (BPH), Nilaparvata lugens (Stål), is a typical insecticide-induced resurgence rice pest that causes severe damage to rice in Asian countries. Previous studies have shown that the fungicide Jinggangmycin (JGM), used to control rice sheath blight disease, can stimulate BPH fecundity; however, the molecular mechanism remains to be further explored. In this study, based on transcriptomic analysis, we found that the PI3K-Akt signaling pathway was significantly enriched in BPH after feeding on JGM-treated rice, where the NlPR-L and NlABD4-L genes were significantly upregulated.

As the prevalence of dementia rises exponentially globally, instituting practices to support the dying process of people affected by dementia is a public health priority. However, end-of-life quality indicators such as place of death provide limited information about the totality of the dying process. Hence, this study's aim was to identify factors affecting the relatively understudied concept of final place of care (where care was received in the last three days of life i.

Dung beetles (Coleoptera, Scarabaeoidea) support several ecological processes and services making them important ecosystem engineers. The dung beetle gut microbiota is involved in many of these ecological services. In the present study, we analyzed the microbiota of 90 individuals of three species feeding on different dung types.

Background: As a polyphagous agricultural pest of global significance, Aphis gossypii exhibits substantial population differentiation and inflicts damage across a broad host range, including economically important leguminous crops. This study aimed to clarify the adaptation of three A. gossypii haplotypes (Hap1, Hap3, Hap4) to four legume hosts: cowpea (Vigna unguiculata) varieties Zhongshouluchangfeng (ZLC) and Zhongshoucuichangfeng (ZCC), hyacinth bean (Lablab purpureus) and winged bean (Psophocarpus tetragonolobus).
