Abstract
Buprofezin (2-tert-butylimino-3-isopropyl-5-phenyl, 3,4,5,6 tetrahydro-2-thiadiazine-4-one) sprayed on cotton seedlings under greenhouse conditions suppressed embryo genesis and progeny formation of the sweet potato whitefly (SPWF), Bemisia tabaci (Gennadius). The estimated concentration for 50% inhibition of egg hatch applied through adults was ca. 15 mg/liter and that for 50% cumulative larval mortality was 6 mg/liter. Length of female exposure to buprofezin correlated well with the effect on embryo genesis, resulting in total suppression at exposure time >24 h. Buprofezin was persistent under greenhouse conditions; spraying concentrations of 62.5 and 125 mg/liter resulted in 50% inhibition of egg hatch at 4 and 7 d after application, respectively, and suppression of >95% of progeny formation up to 26 d after application. In comparative assays with fenpropathrin, buprofezin affected embryo genesis and larval stages, while fenpropathrin especially affected adults and oviposition. At concentrations of 125 and 250 mg/liter under field conditions, buprofezin strongly suppressed infestation by SPWF.
