摘要
黄板诱虫以其无污染,对人、畜无害,操作简单,持效期长,见效快的5大优点,被广泛应用于果园的害虫防治中.为了探索果园悬挂黄板诱蚜的生态效应,对苹果园悬挂的黄板诱虫情况进行了调查,结果表明：不同时期果园黄板诱集到的昆虫种类和数量不同,其中害虫以蚜科数量最多,占总害虫量的73.27％,益虫以蚜茧蜂科的数量最多,占总益虫量的88.93％;从益害比来看,在4月下旬到6月上旬,各时期益害比在1∶74.1～1∶13.7之间变化.果园悬挂的黄板不但可以诱集蚜虫,也可诱集大量的害虫天敌.因此,利用黄板防治果园蚜虫需谨慎.
Yellow sticky card,with its five advantages such as non-pollution,harmless to people and livestock,simple operation,hold along effect,and rapid reaction,is widely used in the pests prevention in orchard.In order to investigate the ecological influence resulting from trapping aphids by using yellow sticky card in orchard,the effect of yellow sticky card was studied.The results showed that the species and number of insects of orchard trapped on yellow sticky card were different in different periods.The aphid and the aphidiidae were most,amounting for 73.27％ of the total number of pests and 88.93 ％ of the total number of beneficial insects,respectively.The results also showed that in late April to early in June,the ratio of natural enemies to pests in different periods was changed between 1 ∶ 74 and 1 ∶ 13.7.Yellow sticky card can not only trap aphids,also collect many natural enemies.Therefore,there is a time for caution when we use yellow sticky card to prevent aphids in orchard.
