摘要：早竹作為筍用竹種，具有可觀經濟價值。近年來，隨著早竹林經營年限不斷增長，其病蟲害發生在逐年加重，成為影響早竹林經營的重要危害。南京高淳地區，剛竹泰廣肩小蜂和竹泰廣肩小蜂對早竹林生長、產筍等產生危害。以4種不同化學藥劑(噻蟲啉，吡蟲啉·甲氨基阿維菌素，氯氟氰菊酯和林得保殺蟲粉劑)對早竹林進行噴灑試驗，結果表明：藥劑效果以3%噻蟲啉微囊懸浮劑最為顯著，其中稀釋2 000倍的噻蟲啉效果最佳，短枝受害率控制在3%左右；10%吡蟲啉·甲氨基阿維菌素苯甲酸鹽可溶液劑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懸浮劑試驗效果最差。

Abstract：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.

早竹(Phyllostachysviolascens)為禾本科竹亞科剛竹屬植物，是一種優良的筍用竹種，主要分布在浙江、安徽和江蘇等地。因其具有出筍早、筍期長、產量高、品質好、經濟效益高等特點成為深受廣大竹農喜愛的筍用竹種[1]。……
