Pesticides can be found in beehives for several reasons, including contamination from surrounding cultivars; yet one of the most pertinent is related to fact that beekeepers employ acaricides control various types mites, which may accumulate beeswax due their lipophilic nature. In present study, foundation sheets different origins, collected over a period three years, were analyzed detect resid...

Pure cultures of Bacillus cereus, Pseudomonas fluorescens, and Achromobacter sp. were shown to transform five pyrethroid insecticides in the presence of Tween 80. One of the major products, 3-phenoxybenzoic acid, was further transformed to 4-hydroxy-3-phenoxybenzoic acid. Permethrin was the most rapidly transformed of the pyrethroids, with a half-life of less than 5 days.

Disclosing interactions between pesticides and bee infections is of most interest to understand challenges that pollinators are facing and to which extent bee health is compromised. Here, we address the individual and combined effect that three different pesticides (dimethoate, clothianidin and fluvalinate) and an American foulbrood (AFB) infection have on mortality and the cellular immune resp...

Background: Amblyseius andersoni is a common predatory mite occurring in fruit orchards located Europe and North America. Its role preventing spider outbreaks widely recognized, particular when selective pesticides are used. The compatibility between plant protection products mites crucial to preserve their activity. There need investigate the effects of on beneficials using multiple approaches...

A gas chromatographic method was developed for the simultaneous determination of 12 pyrethroids (tefluthrin, bifenthrin, fenpropathrin, cyhalothrin, permethrin, cyfluthrin, cypermethrin, alpha-cypermethrin, flucythrinate, fenvalerate, fluvalinate, and deltamethrin) in tomato puree, peach nectar, orange juice, and canned peas. A miniaturized extraction-partition procedure requiring small amounts...

The Colorado potato beetle (CPB) and the western corn rootworm (WCR) are among world’s most expansive insect pests. aim of study was to assess, for first time in Poland, levels susceptibility to deltamethrin tau-fluvalinate WCR determine current status those active substances CPB. In addition, role oxidative metabolism detoxification pyrethroids was determined using piperonyl butoxide (PBO...
