Effects of Buprofezin on Reproduction of the Greenhouse Whitefly, Trialeurodes vaporariorum (Westwood) (Homoptera: Aleyrodidae)

Abstract

The effects of buprofezin (2-tert-butylimino-3-isopropyl-5-phenylperhydro-l,3,5-thia-diazin-4-one, Applaud®) on oviposition, viability of eggs and hatchlings of the greenhouse whitefly, Trialeurodes vaporariorurn Westwood, Were studied. The number of eggs laid by 0–24 hr old adults treated with buprofezin were reduced, and their fecundity was also reduced. The hatchability of eggs laid by adults treated for more than 24 hr was extremely low, and few hatchlings survived on the treated tomato leaves. This was also true of pre-treated adults: egg hatchability and hatchling survival were both low. As these effects persisted even in adults free from buprofezin for 72 hr, the chemical is considered to be important in controlling a T. vaporariorum population. © 1987, JAPANESE SOCIETY OF APPLIED ENTOMOLOGY AND ZOOLOGY.
