A dramatic increase in pesticide usage in agriculture highlights the need for on-site monitoring for public health and safety. Here, a paper-based sensor combined with a wet system was developed for the simple and rapid screening of organophosphate (OP) and carbamate (CM) pesticides based on the inhibition of acetylcholinesterase (AChE). The paper-based sensor was designed as a foldable device ...

The entomopathogen Beauveria bassiana (Bals.) Vuill. (Ascomycota: Hypocreales) can colonize plants endophytically and stimulate the production of secondary plant metabolites with anti-herbivore activities. We assayed topical virulence B. to Aphis gossypii Glover (Hemiptera: Aphididae), effects cucumber inoculation this fungus on metabolites, physiological consequences for aphids that fed these ...

Aquatic ecosystems are exposed to multiple stressors such as agricultural run-off (ARO) and climate-change related increase of temperature. We aimed determine how ARO the frequency its input can affect shallow lake through direct indirect effects on primary producers consumers, whether warming mitigate or reinforce impact ARO. performed a set microcosm experiments simulating using cocktail thre...

Background and purpose: Widespread use of plant pesticides in agriculture resulted in increasing concerns about pesticide hazards. In this research, the residual levels of pesticides in melons were evaluated by gas chromatography-mass spectrometry (GC-MS). Materials and methods: In this study, 75 samples of melons in Tehran market were used for simultaneous analysis of a variety of common pest...

Glutathione S-transferases (GSTs) are one of the major families of detoxifying enzymes that detoxifies different chemical compounds including insecticides in different insect species. Among the GST subclasses, sigma GSTs are found to be the most abundant and conserved among different insect orders. These GSTs are found to play an important role in lipid peroxidation as well as detoxification. C...

Fifty samples of honey collected from local markets of Portugal and Spain during year 2002 were analyzed for 42 organochlorine, carbamate, and organophosphorus pesticide residues. An analytical procedure based on solid-phase extraction with octadecyl sorbent followed by gas chromatography-mass spectrometry (GC-MS), for organochlorines, and by liquid chromatography-atmospheric pressure chemical ...

BACKGROUND In order to increase our knowledge on the susceptibility of entomopathogenic nematode (EPN) species to agrochemicals, the compatibility of the infective juveniles (IJs) of the EPN (Steinernema and Heterorhabditis) with eight chemical and bio-insecticides was investigated under laboratory conditions. The effect of direct IJ exposure to insecticides for 6 and 24 h was tested in a Petri...
