Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape
Pest Management Science, EarlyView.Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Zhongguo youzhi旨在提高牦牛脂肪的综合利用，以新鲜的牦牛脂肪为原料，分别采用酵母葡聚糖、活性干酵母、β-环糊精、茶多酚对牦牛脂肪进行脱腥处理，以牦牛脂肪所炼制的牦牛油腥味值作为评价指标，采用单因素实验优化4种脱腥方法的条件，并采用顶空固相微萃取-气相色谱-质谱联用(HS-SPME-GC-MS)技术对脱腥处理前后牦牛脂肪所炼制的牦牛油的挥发性风味物质组成及含量进行分析，采用相对气味活度值（ROAV）确定牦牛脂肪可能的腥味物质，并对脱腥处理前后牦牛油进行感官评价。结果表明：4种脱腥方法的最佳条件为酵母葡聚糖质量分数1.2%、

Evaluating the efficacy of tagging adhesives for insect tracking
Agricultural and Forest Entomology, EarlyView.Two‐part epoxy resin delivered the strongest RFID tag adhesion on carabid beetles, exceeding polyvinyl acetate, cosmetic latex and cyanoacrylate adhesives. Adhesive performance was consistent across Harpalus, Leistus and Poecilus; species effects were non‐significant, supporting a broadly applicable protocol for carabid RFID tagging studies.

British Journal of Pharmacology, EarlyView.Cannabidiol (CBD) and cannabigerol (CBG) alleviate hepatic steatosis in obese mice by shifting energy buffering towards phosphocreatine and enhancing lysosomal lipid degradation and trafficking. These effects are associated with increased creatine kinase activity and lysobisphosphatidic acid (LBPA) levels, highlighting a previously unrecognised ...

Insects and Survival: A Review of Primary and Secondary Defense Strategies
Entomologia Experimentalis et Applicata, EarlyView.Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.
