摘　　要：为评价玉米植株上不同放蜂位置对两种赤眼蜂防治玉米螟效果的影响,采用盆栽控制试验,分别设置玉米心叶内、盆栽土壤表面及玉米叶片背部3个接蜂点,每点分别单独、混合释放两种赤眼蜂,研究同一蜂种不同释放方式对玉米螟的控害效果。结果表明,在同一位置接蜂,单独接玉米螟赤眼蜂和混合接蜂在卵块寄生率、卵粒寄生率、玉米螟卵中的总出蜂数等指标均高于单独接松毛虫赤眼蜂。当接入蜂种相同而位置不同时,在心叶内接蜂玉米螟卵粒寄生率最高,玉米螟赤眼蜂在心叶内接蜂的蜂卡羽化率高于土壤表面和叶片背部接蜂;松毛虫赤眼蜂在3个位置上差异不显著。在玉米心叶内单独释放玉米螟赤眼蜂或者混合释放赤眼蜂对玉米螟的防治效果最好。Trichogramma dendrolimi by mass production was popularly applied to control Asian maize borer,Ostrinia furnacalis.Different releasing methods of the same Trichogramma species affect the control efficacy to O.furnacalis.Experiments were conducted to evaluate the control effects of the two Trichogramma species on O.furnacalis on different positions,in whorl,on soil surface and the back of leaves.Treatments with releasing T.ostriniae and combined releasing method of the two Trichogramma species could increase parasitism rate of egg masses,parasitism rate of eggs of O.furnacalis and total number of offspring compared to release T.dendrolimi when the wasps were released in the same position.Treatments with releasing wasps in whorl of maize had the higher parasitism rate of eggs of O.furnacalis than other treatments in terms of the same species of Trichogramma.Emergence rate of T.ostriniae in wasp cards in whorl of maize was higher than other positions,but emergence rate of T.dendrolimi in wasp cards was not significantly different among all the three positions.Conclusion exhibit that only releasing T.ostriniae or combined wasp card of T.dendrolimid and T.ostriniae in whorl of maize can obtain the most efficacy to control O.furnacalis.
