摘要
为了提高粘虫板对豆类蔬菜白粉虱的防治效果,调查研究了白粉虱不同虫态卵、若虫和成虫对不同豆类蔬菜、同一豆类蔬菜不同部位和成虫对不同粘虫板颜色的趋性差异。结果表明:不同豆类蔬菜中,白粉虱成虫对荷兰豆的趋性最强,成虫总数高达45.85头,成虫总数由高到低的排序为荷兰豆>长豇豆>豌豆>刀豆>菜豆>扁豆>四棱豆。同一豆类蔬菜不同部位上,卵和成虫均在老叶上数量最高,若虫除豌豆外,均在嫩叶上数量最高。行间悬挂不同颜色粘虫板后,黄色和绿色粘虫板的成虫诱杀数量较高,高达44.22头/板和42.73头/板,与其他颜色粘虫板间差异均达到极显著水平(P<0.01)。
In order to increase control effects of sticky card on Trialeurodes vaporariorum of leguminous vegetable, the tendency difference of different pest state eggs, nymphs, and adults to different leguminous vegetable, different part of same leguminous vegetable, and adult pests to different color of sticky card were investigated.The result showed that the tendency of Trialeurodes vaporariorum adult pest to Pisum sativum var.saccharatum was the strongest in different leguminous vegetables, the total number of adults was 45.85,the rank from high to low of total number of adult pest was Pisum sativum var.saccharatum﹥Vigna unguiculata subsp.sesquipedalis﹥Pisum sativum L.﹥Canavalia gladiata(Jacq.) DC.﹥Phaseolus vulgaris Linn﹥Lablab-purpureus(Linn.) Swee﹥Psophocarpus tetragonolobus(Linn.) DC. The number of eggs and adult on old leaf was the highest on the same leguminous vegetable, the number of nymphs on tender leaf was the highest except Pisum sativum L.The number of murders of yellow and green sticky card were the higher after different color sticky cards were hanged between lines, which was 44.22/card and 42.73/card separately, the differences all reached extremely significant levels(P<0.01).
