1985—1988年在大别山区于喷25%灭幼脲Ⅲ号胶悬剂后,对林问残存幼虫后效进行观察研究结果表明,此药对喷洒当代各虫态均有较好的防治效果,残存幼虫化蛹率比对照低74.5%;成虫产卵量比对照低47.6%;对下代后效作用不明显,但防治区虫口恢复率显著低于对照。
1985-1988 in the Dabie Mountains in the spraying of 25% mefenal suspension No. Ⅲ, Lin observed residual larvae observed after the results showed that the drug spraying on the status of each have a better control effect, The residual larval pupation rate was 74.5% lower than that of the control. The adult fecundity was 47.6% lower than that of the control, but the effect was not obvious to the next generation. However, the recovery rate of the pest population in the control area was significantly lower than that of the control.
