灭幼脲可以同时杀死黄地老虎的卵、幼虫,亦可杀死部分成虫,并且可使未被杀死的雌成虫产卵和卵孵化受到极大的抑制。灭幼脲油剂杀死幼虫84.03%～100%左右,胶悬剂杀死幼虫82.64～98.61%左右;灭幼脲油剂杀死卵83.33～92.86%左右,胶悬剂杀死卵5.55～22.22%左右;灭幼脲油剂可杀死成虫8.33～9.03%左右,胶悬剂可杀死成虫7.64～9.74%左右。灭幼脲油剂处理成虫后,相对产卵率降至7.90～12.96%左右,相对孵化率降至0.80～2.76%左右;胶悬剂处理成虫后,相对产卵率降至10.82～16.43%左右,相对孵化率可降至2.76～5.88%。
Chlorbenzuron can simultaneously kill yellow tiger eggs, larvae, but also kill some adults, and can kill the female adults oviposition and egg hatching was greatly inhibited. Chlorbenzuron oil killed about 84.03% ~ 100% of the larvae, insecticides kill 82.64 ~ 98.61% of the larvae; viroid urea killed 83.33 ~ 92.86% of the eggs, plastic suspension killed eggs 5.55 ~ 22.22 %; Virginina oil can kill adult 8.33 ~ 9.03% or so, plastic suspension can kill adult 7.64 ~ 9.74%. The relative oviposition rate decreased to about 7.90-12.96% when the imazapic was applied to adult worms, and the relative hatching rate dropped to 0.80-2.76%. After the insecticides were treated with the suspending agent, the relative spawning rate dropped to 10.82-16.43% , The relative hatching rate can be reduced to 2.76 ~ 5.88%.
