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.

Disc‐Toroid Hybrid Lipid Nanoparticles for Efficient Drug Encapsulation and Subcutaneous Delivery
Small, EarlyView.This study demonstrates sub‐50 nm solid‐lipid nanoparticles with long‐term stability, high drug loading, and strong tissue compatibility. Disc‐toroid morphology is confirmed and may play a role in cellular interactions, while low cytotoxicity and minimal systemic permeation confirm depot‐like behavior. These nanoparticles represent a versatile platform

不同离子对核桃蛋白结构及功能特性的影响Effects of different ions on the structure and functionality of walnut protein
Zhongguo youzhi为了有效提高核桃蛋白的利用率，拓展核桃蛋白在食品领域的应用范围，采用阴离子（Cl-、PO3-4、S2O2-3、HCO-3）和阳离子（Na+、K+、Mg2+、Ca2+）对核桃蛋白进行改性，并对改性后核桃蛋白的结构与功能特性进行研究。结果显示：阴离子PO3-4、HCO-3 和阳离子Na+、Mg2+增加了核桃蛋白的巯基含量；除了Cl-和K+，其他6种离子改性核桃蛋白的二硫键含量均下降，其中HCO-3改性核桃蛋白下降最多；8种离子对核桃蛋白的亚基组成无影响；Cl-、PO3-4、Na+和Ca2 ...

Insect Science, EarlyView.We carried out functional studies using Dicer‐substrate small interfering RNAs (DsiRNAs), targeting the sex determination genes Cctransformer (Cctra) and Cctransformer‐2 (Cctra‐2) in the Mediterranean fruit fly (Ceratitis capitata). Microinjection of DsiRNAs into XX embryos (0‐1 h old) rapidly triggered the expression of male‐specific Cctra isoforms ...

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.
