几种昆虫生长调节剂对云斑天牛成虫产卵量及子代卵孵化的影响

研究了６种昆虫生长调节剂对云斑天牛成虫和子代卵的生物活性。结果表明，灭幼脲１号、卡死克、灭幼脲３号、抑太保对成虫产卵量及子代卵孵化有明显抑制效果。其中灭幼脲１号和卡死克效果最佳，综合抑制率分别为８７．０％和８１．７％；灭幼脲３号和抑太保活性也较高，综合抑制率分别为７５．７％和６５．３％；虫死净和优乐得活性较低，综合抑制率为３１．５％和２２．５％。

THE BIOLOGICAL ACTIVITIES OF INSECT GROWTH REGULATORS AGAINST ADULT BATOCERA HORSFIELDI (HOPE)

Tests of the biological activities of six kinds of insect growth regulators (IGRs) to the adult Batocera horsfieldi and its progeny eggs were carried out in the laboratory. The number of eggs laid per female among all treatments were reduced except chlorfluazuron treatment. Triflumuron had the highest inhibiting effect on the number of eggs laid per female. The egg production laid per female of triflumuron treatment decreased by 61.0% in comparison with that of control treatment. After adults ingested diflubenzuron, the dates when egg production was 50% and 86% respectively, were obviously postponed. Diflubenzuron, flufenoxuron, triflumuron, and chlorfluazuron had obviously inhibiting effects on the egg production per female and the hatching of progeny eggs. Among six kinds of IGRs, diflubenzuron and flufenoxuron were the most effective, the integrated inhibition rates (IIR) were 87.0 % and 81.7%, respectively. Triflumuron and chlorfluazuron had also a high activity, the IIR was 75.7% and 65.3%, respectively. By comparison, buprofezin and RH 5849 had a lower activity, the IIR was 22.5% and 31.5%, respectively.
