摘要
灰斑古毒蛾是严重影响巴彦淖尔地区飞播造林成果的主要食叶害虫之—,危害柠条、杨柴、花棒、沙冬青、紫蒿等。以幼虫取食植物的嫩芽、叶和花苞,严重时将全株丛叶子和花苞吃光,不仅影响生长,而且极易造成树势衰弱,甚至死亡。因此,控制灰斑古毒蛾在该地区的发生蔓延尤为重要。本试验通过林间选用4种药剂针对2~3龄幼虫采用不同倍率进行了人工地面喷雾防治药效实验,筛选较好的防治方法及药剂。
Gray-spots orgyia antiqua is one of the main leaf-eating pests that seriously affect the aerial seeding afforestation results in Bayannur district,which harms Caragana korshinskii,poplar wood,flower stick,Ammopiptanthus mongolicus,Artemisia ordosica and so on.Larvae feed on the buds,leaves of plants.In severe cases,they eat up the leaves and buds of the whole plant cluster,which not only affects the growth,but also easily causes the tree to weaken or even die.Therefore,it is particularly important to control the occurrence and spread of gray-spots orgyia antiqua in this area.In this experiment,four kinds of pesticides were selected in the forest to carry out artificial ground spray control efficacy experiments with different ratios for 2~3 instar larvae,and better control methods and pesticides were screened.
