摘  要：
为探寻不同生物防治资源协同控制害虫的可行性,研究了斑痣悬茧蜂和斜纹夜蛾核多角体病毒(SINPV)联合作用于斜纹夜蛾时两者的相互影响,以及昆虫生长调节剂氟啶脲对斑痣悬茧蜂的影响。结果表明,在SINPV浓度为10~6PIB/ml、10~7PIB/ml和10~8PIB/ml 3个浓度下,无论是病毒和寄生蜂—同处理,还是先寄生蜂处理1d后再病毒处理,斑痣悬茧蜂对SINPV的侵染力和侵染速度均无显著影响。联合处理时病毒对寄生蜂也无不良影响,蜂后代结茧数与对照无差异,仅缩短了先寄生蜂后10~6 PIB/ml SlNPV处理组寄生蜂从卵到茧的发育历期。从氟啶脲对斑痣悬茧蜂的影响来看,寄生蜂寄生经1.25 mg/L氟啶脲处理后的甜菜夜蛾,其后代发育历期和结茧均未受影响,仅羽化受影响。寄生蜂成虫直接经10 mg/L、20 mg/L和40 mg/L(田间推荐剂量)氟啶脲处理后,均对后代结茧和发育历期等无显著影响。表明斑痣悬茧蜂可较安全地与一定浓度范围斜纹夜蛾核多角体病毒或氟啶脲联合用于夜蛾类害虫的控制。

摘  要：
In order to evaluate the feasibility of combination of different biological agents to control insect pests,the interaction of Meteorus pulchriconis with Spodoptera litura neuclopolyhedrovirus(SINPV) were studied,and the impact of chlorfluazuron,an insect developmental regulator,on Meteorus pulchriconis was also investigated.The results showed that the biological activities and killing speeds of 10~6 PIB/ml SINPV,10~7 PIB/ml SINPV and 10~8 PIB/ml SINPV combined with Meteorus pulchriconis were not significantly different from those of SINPV alone.And there was also no negative effect of SINPV on pupation of Meteorus pulchriconis,except that duration from egg to pupation was shortened when Spodoptera litura larvae were parasitized for ld and then infected by 10~6 PIB/ml SINPV.It was also found that chlorfluazuron only impacted the emergence of Meteorus pulchriconis when they parasitized S.exigua treated with 1.25 mg/L chlorfluazuron.As the para- sitoid was treated with 10 mg/L,20 mg/L and 40 mg/L chlorfluazuron in adult stage,pupation and developmental duration of their offsprings were not affected.The results indicated that Meteorus pulchriconis could be combined with SINPV or chlorfluazuron to control noctuid moths safely.
