绿鳞象甲在甘蔗大豆间作田种群分布及取食性研究

间作模式是作物虫害综合防治的一种重要手段.通过田间甘蔗与大豆间作（1∶1模式）、单作种植,调查绿鳞象甲发生规律、种群数量及空间分布.结果表明：绿鳞象甲成虫在大豆上重要发生期为5月上、中旬,甘蔗上主要集中在5～6月;间作或单作大豆田种群数量均高于甘蔗田;间作田甘蔗上种群数量高于单作田,间作田大豆上种群数量则少于单作田;在甘蔗与大豆间作模式下均为聚集分布,强度随密度的上升而升高.室内取食性选择试验表明：绿鳞象甲雌、雄成虫均喜食大豆叶片,差异极显著;取食相同寄主时,雌虫取食量高于雄虫....

Intercropping is an important means of the pest integrated control techniques. In this study, occurrence trend of Hypomeces squamosus population and spatial distribution were investigated in sugarcane-soybean intercropping 1： 1 mode. The results showed that, the peak period of H. squamosus occurred in sugarcane was beginning and middle third of a month in May. In soybean, the peak period was May and June. The number of H. squarnosus in soybean monoculture or intercropping was significantly higher than that in sugarcane. The number of H. squarnosus in sugarcane monoeuhure was significantly higher than that in intercropping. The numbe
