    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0.1243;保苗、保产效果分别为86.91%和77.13%,且其主要的控制机理是对成虫的显著拒避作用。

    Abstract:

    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.
