摘　　要：早竹作为笋用竹种,具有可观经济价值。近年来,随着早竹林经营年限不断增长,其病虫害发生在逐年加重,成为影响早竹林经营的重要危害。南京高淳地区,刚竹泰广肩小蜂和竹泰广肩小蜂对早竹林生长、产笋等产生危害。以4种不同化学药剂(噻虫啉,吡虫啉·甲氨基阿维菌素,氯氟氰菊酯和林得保杀虫粉剂)对早竹林进行喷洒试验,结果表明:药剂效果以3%噻虫啉微囊悬浮剂最为显著,其中稀释2 000倍的噻虫啉效果最佳,短枝受害率控制在3%左右;10%吡虫啉·甲氨基阿维菌素苯甲酸盐可溶液剂和林得保的效果次之,短枝受害率下降近2%;10%高效氯氟氰菊酯微囊悬浮剂试验效果最差。Phyllostachys violascens is an important economic bamboo species,whose shoots are edible. Recently,the planting areas of the bamboo gradually become larger because of its economic value. However,the damages due to such insect pests as Tetramesa phyllostrachitis Gahan and Tetramesa bambusae Philips increase as well. To check the spraying effects of four kinds of insecticides（ Imidacloprid,Thiacloprid,λ-Cyhalothrin and Lindebao） with different concentrations,we carried out a field experiment in the forest of P. violascens. The analysis of variance was used to compare the significance of differences among the groups of different concentrations and control group. The results showed that the effect of Thiacloprid was the best,Imidacloprid and Lindebao were better and,λ-Cyhalothrin ranked worst.
