摘    要:用灭蝇胺、氟铃脲等6种昆虫生长调节剂和对比药剂辛硫磷LC40-50浓度处理葱蝇1龄和3龄幼虫,观察对其生长发育和繁殖的影响;并且研究了葱蝇成虫取食药剂对其繁殖力的控制效应。结果表明:6种药剂中除虫酰肼外,其余都对葱蝇幼虫发育历期、化蛹率、成虫产卵前期、成虫寿命、产卵量有很大影响,对其生长发育和繁殖表现出显著不利性。其中灭蝇胺和氟铃脲处理1龄幼虫后,存活幼虫的历期和成虫产卵前期各延长3天,化蛹率降低26.7%~30.0%,成虫寿命缩短22.3~24.3天,产卵量降低35.5%~49.9%;处理3龄幼虫主要导致产生畸形蛹,且正常羽化的成虫寿命降低18.0~20.67天,产卵量降低45.7%~57.8%。成虫连续取食用牛奶稀释的2 000倍的药液,能导致产卵前期延长、产卵量减少、卵孵化率降低,幼虫死亡率极高,达95%以上。结果提示,利用成虫补充营养的特性,将灭蝇胺和氟铃脲等混入牛奶或糖水中诱集成虫取食,可有效降低成虫的繁殖力,有助于实现对葱蝇的无公害治理。

关 键 词:葱蝇  昆虫生长调节剂  生长发育  繁殖力

Abstract:The effects of six IGRs in LC40-50 concentration on development and adult fecundity of onion maggot, Delia antique (Meigen) (Diptera: Anthomyiidae) were observed by treating the 1st and 3rd larvae of onion maggot with phoxim as a control. Adult fecundity was also investigated through continuous feeding the adults on milk solution with different IGRs. The results showed that, except tebufenozide, the other 5 IGRs had obviously adverse effects on larval development periods, pupation rate, pre-oviposition periods, adult longevity and eggs laid per female. Both larval development period and pre-oviposition period were prolonged by about 3 days, pupation rate was reduced by 26.7%-30.0%, adult longevity was decreased by 22.3-24.3 days and eggs laid per female was reduced by 35.5%-49.9% when the 1st instars were treated with cyomazine and hexaflumuron. Whereas, when the 3rd instars were treated with these two IGRs, deformed pupae without resulting in larval death was observed, eggs laid per female was reduced by 45.7%-57.8% and adult longevity was shortened by 18.0-20.67 days. Feeding the adults with milk solution with different IGRs in 1∶2000 (IGR∶milk) prolonged pre-oviposition period, decreased eggs laid per female and egg hatchability, remarkably increased mortality of 1st instar larvae which was as high as more than 95%. The results indicated that, taking advantage of the adult trait of nutrient supplement, cyromazine and hexaflumuron could be added into milk or sugar solution to lure the adult to reduce its fecundity effectively, which could make the environment-friendly management of onion maggot come true.
Keywords:Delia antique  insect growth regulator  growth and development  fecundity
