为了测试蒲螨是否能够捕食食叶害虫松阿扁叶蜂和椰心叶甲,开展了蒲螨捕食这2种害虫的室内实验。结果表明,蒲螨可有效捕食这2种害虫,6d后松阿扁叶蜂的死亡率在90%以上,3d后椰心叶甲的死亡率达到100%。同时还探讨了试验环境、油松树皮、叶甲习性和高温对试验结果的影响。
In order to test whether Po-mites can prey on the leaf-eating pests of the pine leaf-bee and coconut leaf-beetle, laboratory experiments on the predation of these two pests by Po-mites were carried out. The results showed that Po pu mite can effectively prey on these two kinds of pests. After 6 days, the death rate of Phyllostachys pubescens was over 90%. After 3d, the mortality of Coprinus comatose reached 100%. At the same time, the influence of experimental environment, bark of pine tree, habit of leaf turtle and high temperature on the test results were also discussed.
