Abstract:
... Bumblebees exposed to neonicotinoid pesticides collect less pollen on foraging trips. Exposed bumblebees are also slower to learn to handle flowers, which may account for reduced pollen collection. It is unclear, however, why neonicotinoid exposure slows learning to handle flowers. We investigated the effect of imidacloprid, a neonicotinoid pesticide, on bumblebee motor learning using a lab model ...

Abstract:
... Pest management, which is critical for global crop productivity, is hampered by rapidly evolving insecticide resistance in insect pests. The ability to manage the development of insecticide resistance is thus vital. Nitric oxide (NO) is a ubiquitous signaling molecule with important functions in a variety of biological processes. Here we show that imidacloprid-resistant brown planthoppers (BPH) ar ...

Abstract:
... EW has been proposed as a sanitization method for home use to reduce chemical and biological hazards in fresh products. Most studies have evaluated exposure times of 1–10 min which may be too long for processing fresh produce. The aim of this work was to evaluate if short exposure times (15, 30 or 45 s) to electrolyzed water (EW – 50 ppm of free chlorine) were enough to significantly reduce Salmon ...

Acute (96‐h) toxicities of 5 systemic insecticides (chlorantraniliprole, cyantraniliprole, flupyradifurone, flubendiamide, and sulfoxaflor) were tested on larval Chironomus dilutus and compared with the neonicotinoid imidacloprid. Three insecticides were less acutely toxic than imidacloprid (2.5–25 times lower). However, chlorantraniliprole and cyantraniliprole were 1.5 to 1.8 times more toxic to ...
