以冀中北部的廊坊市固安县为试验点,对瓢虫的生物生态学及生存对策进行研究,目的在于量化出防护林对农田系统的生态作用辐射范围及阈值。通过对天敌瓢虫生物学信息进行系统的研究,以量化的形式揭示出林带—天敌—害虫关系中天敌节肢动物对农田害虫的作用范围,结果表明,春末夏初及作物生长成熟期,龟纹瓢虫对比其他瓢虫具有绝对优势;大多数环境的龟纹瓢虫都占优势;在作物耕种前和生长早期,瓢虫种群基本集中在林带;不同的作物生境间,瓢虫存在一定的选择趋向性,对间作田的趋向性较农田单一作物斑块更为明显。

Taking Gu＇an county of Langfang city in central Hebei as a testing point,ecology survival strategies about ladybug were studied;the purpose is to quantify the radiation range threshold of ecological role for farmland system by protection forest.Through study on biological information on ladybugs,range of influence of arthropoda on pests in the field under relationship among shelterbelt,natural enemies pests by the form of quantization was revealed.Result shows that： in late spring,early summer in the growth of crop maturity,Propylea japonica has an absolute advantage compared to other ladybugs;Propylea japonica are all dominant in most environment;ladybug populations basically concentrated in the shelterbelt during crops before harvested or at an early stage;ladybug,which exist certain selection tendency among different crop habitats,has more obvious tendency on intercropping field than in single-crop patches of farmland.
