诱集植物和性诱剂及引诱剂组合对辣椒斜纹夜蛾的诱集效果

Effects of Trap Crop and Sex Attractants-Attractants Combination on Trapping of Prodenia litura on Pepper

为辣椒斜纹夜蛾绿色防控提供参考,通过田间试验研究辣椒与不同作物间作及引诱剂+性诱剂组合对斜纹夜蛾的诱集效果。结果表明:芋头和向日葵与辣椒间作对斜纹夜蛾的产卵和幼虫诱集效果最好,其每100株植株卵块量分别为60块和69块,幼虫数分别为6157头和2097头;间作面积比例为1∶12对产卵和幼虫的诱集效果最佳;性诱剂+引诱剂(醋∶白酒∶糖∶敌百虫∶水为1∶1∶0.5∶0.5∶10)对斜纹夜蛾成虫的诱集效果最佳,200m^2内共诱集成虫937头。

The effects of pepper intercropping with different crops and attractants+sex attractants combination on trapping of Prodenia litura are studied by a field test to provide a reference for green prevention and control of P.lituraon pepper.Result:Pepper intercropping with taro or sunflower has the best effect on egg-laying and larvae trapping of P.litura,with egg mass per 100 plants of 60 and 69,and larvae number of 6157 and 2097 respectively.The 1∶12 of intercropping area ratio has the best effect on egg-laying and larvae trapping.Sex attractants+attractants(vinegar∶liquor∶sugar∶dipterex∶water=1∶1∶0.5∶0.5∶10)has the best effect on trapping adult P.litura with a total of 937 adults trapped in an area of 200 m^2.
