Effect of common pesticides on Q-biotype Bemisia tabaci (Gennadius) collected from three major tomato-growing districts in Aichi Prefecture

Abstract

We examined the effect of 13 pesticides by using the kidney bean leaf-dipping method on the 1st instar larvae, 3rd-4th instar larvae, and adults of Q-biotype Bemisia tabaci (Gennadius) collected from three major tomato-growing districts in Aichi Prefecture. The effects of the pesticides on Q-biotype were almost the same as previously reported, whereas those of pyridaben WP and tolfenpyrad WP were lower. In addition, the appropriate timing for applying the pesticides in forcing culture, the main tomato cultivation method in Aichi prefecture, is discussed based on our study results.
