摘要
2004年在贵州省龙里县水场乡对夏秋反季节豇豆豆荚螟田间消长进行了调查。结果表明：豆荚螟在花、荚上的盛发期为8月24日～9月18日，高峰期在8月29日～9月13日。药剂防治应从8月24日开始，5～7d喷1次，连续防治2～3次。
The investigation on population dynamics of Etiella zinckenella for off-season cowpea and its control was conducted in Shuichang town, Longli county, Guizhou. The results showed that the occurrence peak of Etiella zinckenella in flowers and pods was between 24 August and 18 September and the emergence peak was between 29 August and 13 September. The insecticide should be firstly sprayed on 24 August, spraying one time every five to seven days and spraying two or three times consecutively.
