Laboratory feeding trials were conducted to assess the comparative impact of registered and new unregistered insecticide-treated bran baits on nontarget epigcal arthropods. Yellow mealworm beetles and larvae (Tcllebrio molitor, L.) (8 surrogate, surface-dwelling tenebrionid) were individually housed in containers and exposed to five different dosages (quantities) of bran bait treated with three...

A rapid and simple method has been developed for the analysis in olive branches of two insecticides currently used in olive pest control, dimethoate and alpha-cypermethrin. The effects of analytical conditions on pesticide recovery and the optimal extraction conditions were evaluated by means of a factorial design. The use of this chemometric tool in analytical method development allows the ide...

Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), feeding injury results in discoloration and a rough texture on cabbage, Brassica oleracea capitata (L.), leaves, and damage may occur deep inside the head. It has become a key pest of cabbage in the United States and many other countries. Previous studies have indicated poor control using insecticides. The present study identified ...

An effective method for separating and enriching organophosphorous pesticides (OPPs) from vegetables by solvent sublation and the OPPs determination by gas chromatography with flame photometric detector (GC-FPD) has been developed. The effects of organic solvent, nitrogen flow rate, pH of the solution, sublation time etc. on the sublation efficiency of OPPs were investigated in detail, and the ...

Bees are essential pollinators of crops and wild plants their ability to forage pollinate key aspects behaviour. Bee populations under threat, with the use insecticides a contributing factor. Most research has focused on neonicotinoid bee mortality, little is known about impacts foraging delivery pollination services. However, other insecticide classes, such as organophosphates pyrethroids, inc...
