Toxicity of neonicotinoid insecticides to honey bees: laboratory tests
Toxic effects on Apis mellifera L. of the neonicotinoid insecticides Thiametoxam, Clothianidin, Acetamiprid and Thiacloprid were tested in the laboratory. Commercial formulations, dispersed in sugar syrup and water, at the highest dose level marked on the label were used to carry out oral and indirect contact trials on each pesticide.

متن کاملDetermination of emamectin benzoate in medicated fish feed.
A method was developed to quantitate emamectin benzoate in fish feed at levels between 5 and 15 ppm. The active ingredient is extracted from 20 g medicated feed into aqueous-methanolic solvent by overnight shaking. A solid-phase extraction procedure using a 2 g C18 cartridge is then used to concentrate the active residue and remove interfering matrix components. The extracted drug and internal ...
