| Abstract: In order to select safe and efficient chemical agents (combinations) for the control of Bemisia tabaci biotype Q, the efficacy tests of 6 insecticides on Bemisia tabaci biotype Q in southern Hu'nan were carried out. The results showed that 22.4% spirotetramat 1 500 times solution had the best killing effect on the eggs of Bemisia tabaci biotype Q, 10% pyrrolyl ether 750 times solution + 22.4% spirotetramat 1 500 times solution had the best controlling effect on the nymphs of Bemisia tabaci biotype Q, 10% bromocyanamide 1 000 times solution + 22.4% spirotetramat 1 500 times solution had the best controlling effect on the adults of Bemisia tabaci biotype Q. The compound application of 3 kinds of insecticides, such as 22.4% spirotetramat, 10% pyrrolyl ether and 10% bromocyanamide, could achieve ideal control effect in the practical operation of controlling Bemisia tabaci biotype Q in southern Hu'nan. |
