摘　　要：采用烟草处理土壤后可使菜田黄曲条跳甲幼虫密度明显减少 ,对其成虫的拒避率高达 79 79% ,种群趋势指数 (I)降至 1 882以下 ,干扰作用控制指数 (IIPC)为 0 1 2 43;保苗、保产效果分别为 86 91 %和 77 1 3% 。By the soil treatment with tobacco in vegetable field, the larva number of striped flea beetle [ Plyllotreta striolata (F.)] decreased remarkably. The deterrent effect on the adults was 79 81%. The index of population trend (I-value) reduced to 1 882. The interfenence index of population control (IIPC) was 0 124 3, and its protective effect on seeding and yield of vegetable were 86 91% and 77 13% respectively. The control mechanism of tobacco on the population of striped flea beetle was its deterrent effect significantly.
