Effect of Thiacloprid Exposure on Honey Bees Apis mellifera F.

Abstract

An evaluation of the effect of thiacloprid (21.7% SC), an N-cyanoamidine neonicotinoid exposure on honey bees Apis mellifera F. was done under field conditions. Study on foraging behaviour, mortality and food stores were carried out with 500, 325, 250, 125, 62.50, and 31.25 ppm, while 0 ppm concentration served as control. Of these, a significant effect was observed with 500 and 325 ppm as could be observed from the foraging behaviour. Thus, thiacloprid is found to be safe at lower concentrations <250 ppm.
