2004年在贵州独山县城关镇石牛村实施豆荚螟(EtiellazinckenellaTreitschke)对法国细刀豆发生危害调查及无公害农药防治试验。研究结果表明,豆荚螟在法国细刀豆上的危害为第2、3代,主害代为第2代,幼虫危害花、荚和造成虫孔盛期在6月上旬至下旬,高峰期在6月下旬;成虫盛期在6月下旬至7月上旬,高峰期在6月下旬。选择5种无公害农药做田间防效试验,筛选出2种防效较高的农药,防效分别为93 43%～87 75%和98 00%～85 94%。
At Shiniu village,Chengguan town,Dushan county,Guizhou,2004,investigation on injury of Etiella zinckenella Treitschke in thin French bean and its pollution-free control was carried out.The results showed that the thin French bean was injured by the secondary and third generation Etiella zinckenella Treitschke.And the major injury was caused by secondary generation.Abundant Stage,at which larvae injured bean flowers and pods,occurred in June and the injury peak period in last ten days of June.Adult abundant stage and peak period appeared from last ten days of June to first ten days of July.In the 5 harmless insecticides for field experiment,the control efficiency of two achieved respectively 93.43 % to 87.75 % and 98.00 % to 85.94 %,and could be applied in production of thin French bean.
