为探寻小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(SIN-PV)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SIN-PV浓度为10~6PIB/ml、10~7PIB/ml和10~8 PIB/ml 3个浓度下,无沦是病毒和寄生蜂一同处理,还是先寄牛蜂处理1 d后冉病毒处理,斑痣悬茧蜂对SINPV的侵染力和侵染速度均无显著影响.联合处理时病毒埘寄牛蜂也无不良影响,蜂后代结茧数与对照无差异,仅缩短了先寄生蜂后10~6PJB/mJ SINPV处理组寄生蜂从卵刮茧的发育历期.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.寄生蜂成虫卣接经10 ms/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.
為探尋小同生物防治資源協同控製害蟲的可行性,研究瞭斑痣懸繭蜂和斜紋夜蛾覈多角體病毒(SIN-PV)聯閤作用于斜紋夜蛾時兩者的相互影響,以及昆蟲生長調節劑氟啶脲對斑痣懸繭蜂的影響,結果錶明,在SIN-PV濃度為10~6PIB/ml、10~7PIB/ml和10~8 PIB/ml 3箇濃度下,無淪是病毒和寄生蜂一同處理,還是先寄牛蜂處理1 d後冉病毒處理,斑痣懸繭蜂對SINPV的侵染力和侵染速度均無顯著影響.聯閤處理時病毒塒寄牛蜂也無不良影響,蜂後代結繭數與對照無差異,僅縮短瞭先寄生蜂後10~6PJB/mJ SINPV處理組寄生蜂從卵颳繭的髮育歷期.從氟啶脲對斑痣懸繭蜂的影響來看,寄生蜂寄生經1.25 mg/L氟啶脲處理後的甜菜夜蛾,其後代髮育歷期和結繭均未受影響,僅羽化受影響.寄生蜂成蟲卣接經10 ms/L、20 mg/L和40 mg/L(田間推薦劑量)氟啶脲處理後,均對後代結繭和髮育歷期等無顯著影響.錶明斑痣懸繭蜂可較安全地與一定濃度範圍斜紋夜蛾覈多角體病毒或氟啶脲聯閤用于夜蛾類害蟲的控製.

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 SI-NPV on pupation of Meteorus pulchriconis, except that duration from egg to pupation was shortened when Spodoptera litura larvae were parasitized for 1d 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 rag/L, 20 mg/L and 40 mg/L chlorfluazuron in adult stage, pupation and developmental duration of their offsprings were not affected. The resultsindicated that Meteorus pulchriconis could be combined with SINPV or chlorfluazuron to control noctuid moths safely.
