- 摘要:
- 以井上蛀果斑螟为试虫，采用浸渍法和药膜法处理井上蛀果斑螟的卵、幼虫和成虫，研究了氟啶脲、虫酰肼和茚虫威对井上蛀果斑螟的室内生物活性。结果表明：3种杀虫剂对井上蛀果斑螟的存活和繁殖均有一定抑制作用，且用药浓度提高，其抑制效果加大。50 g?L-1氟啶脲乳油400倍液对卵孵化率的抑制作用最强；50 g?L-1氟啶脲乳油400倍液和150 g?L-1茚虫威乳油3 000倍液对初孵幼虫存活率的抑制作用较强，并对存活初孵幼虫蛹的羽化影响较为显著，50 g?L-1氟啶脲乳油400倍液对其化蛹影响最为显著；50 g?L-1氟啶脲乳油400倍液对老熟幼虫存活率的抑制作用最强，50 g?L-1氟啶脲乳油400倍液和150 g?L-1茚虫威乳油3 000倍液对存活老熟幼虫的化蛹和羽化影响较为显著；150 g?L-1茚虫威乳油3 000倍液对成虫存活率抑制作用最强，并对存活成虫的单雌产卵量影响最为显著，50 g?L-1氟啶脲乳油400倍液和20%虫酰肼悬浮剂1 000倍液对其卵孵化率影响较为显著。
- Abstract:
- Assara inouei Yamanaka was used as test insect.The bioactivities of chlorfluazuron，tebufenozide and indoxacarb against eggs，larvae and adults of Assara inouei were studied by immersion and residual film method in the laboratory.The results showed that three insecticides had certain inhibiting effect on survival and reproduction of Assara inouei，and the inhibition effect increased with insecticides concentration increasing.Four hundred-diluted times solution of 50 g?L-1 chlorfluazuron EC had the strongest inhibition effect on egg.Four hundred-diluted times solution of 50 g?L-1 chlorfluazuron EC and 3 000 diluted times solution of 150 g?L-1 indoxacarb EC had the strongest inhibition effect on survival rate of newly hatched larvae and eclosion rate of live larvae，and four hundreddiluted times solution of 50 g?L-1 chlorfluazuron EC showed the most significant inhibition on pupation rate of live larvae.Four hundred-diluted times solution of 50 g?L-1 chlorfluazuron EC was the strongest inhibiting effect on mature larvae survival rate.Four hundred-diluted times solution of 50 g?L-1 chlorfluazuron EC and 3 000 diluted times solution of 150 g?L-1 indoxacarb EC showed the most significant inhibition to pupation rate and eclosion rate of live larvae,3 000 diluted times solution of 150 g?L-1 indoxacarb EC was the strongest inhibiting effect on adult survival rate and single female fecundity of live adult.Four hundred-diluted times solution of 50 g?L-1 chlorfluazuron EC and 1 000 diluted times solution of 20% tebufenozide SC showed the most significant inhibition to egg hatching rate.
