摘要
为对竹卵圆蝽、竹蝗,一字竹象鼻虫、竹笋夜蛾四种竹林主要害虫的综合防治进行经济效益评估,作者在毛竹、篌竹、淡竹林内设立一定数量的标准地进行专题调查研究,其结果是:四年综合防治直接经济效益(包括挽回虫害损失和新增产值)所产生的总产值为3414.29万元,是综合防治总投入数(523.6万元)的6.5倍,其效果十分显著。
Hippota dosalis (Stal), Algedonia coclesalis (Walker), Otidognathus davidis (Fair) and Oligia vulgaris (Butler)are major bamboo's pests. The economic losses of Ph. pubscenns forests caused by H. dorsalis, A. coclesalis and Ot. davidis were 150.06 and 93.90 Yuan/ mu respectively, the ones of Ph. nidularia forests caused by Ot. davidis were 636.51 and 640.44 Yuan/mu respectively. By integrated control, 101.66 Yuan/mu of output value was increased newly, and the saved losses of Ph. pubescens forests caused by H. dorsatis in the order of damage degree, i. e., light, middle, heavy (as same as the following) were 12.08, 45.81, and 128.90 Yuan/mu; 14.48, 35.84, and 92.66 Yuan/mu for A. coctesalis, 14.48, 46.46, and 85.21 Yuan/mu for Ot. davidis. The saved losses of Ph. nidularia forests caused by Ot. davidis were 152.14, 386.68, and 555.22 Yuan/mu, the saved ones of Ph. glauca forests caused by Ol. vulgaris were 66.91, 371.64, and 608.74 Yuan/mu. The sum of saved economic losses plus newly-increased output value was 3,414,290 Yuan which was the 6.5 times of total investment for 4 years of integrated control.
