Abstract：Both foliar spray in laboratory and field trails were conducted to evaluate the effect of thiamethoxam 25 % WG against adults of Bemisia tabaci B-biotype on cucumber seedlings. The laboratory bioassay indicated that the activity of thiamethoxam was 290-fold as much as chlopyrifos, and the results in field trials showed that the controlling effects reached 95.39 % in 3 days. The suitable dosage concentration was 1∶5 000-6 000 dilution for foliar spray.
