愚肖齿舟蛾(Odontosino morosa(Kiria koff))属鳞翅目,是我国舟蛾科特有种之一。首见于云南丽江,省内除丽江外尚分布于曲靖、云龙和宜良三县。该虫曾于1979年9月在本场小白龙营林区华山松纯林内猖獗为害,发生面积2500余宙,其中1378亩严重受害,据标地调查,有虫株率平均95%,平均虫口数144头/株。爱害林木针叶全被吃光,状如火烧,严重影响树势生长。虫灾后,曾耗资万余元发动3500多人上山挖蛹,在严重受害的978亩林中共挖出虫蛹1287公斤,每平方米虫蛹数高达40余头。该虫如此暴发为害华山松,迄今尚属鲜见。为经济、有效地对该虫进行综合治理,我们从1980年起经两年连续饲养观察和林内调查研究,记载了该虫的生活史和部分生物学习性。现将初步研究结果整理报告如下。
Odontosino morosa (Kiria koff) belongs to Lepidoptera, and is one of the most endemic species in China. First seen in Lijiang, Yunnan Province, except in Lijiang, the province is still located in Qujing, Yunlong and Yiliang three counties. The insects had in September 1979 in this field small white Longshan forest Huashan pine rampant damage, the occurrence of an area of 2500 Yuzhou, of which 1378 acres of serious damage, according to the standard survey, the average strain rate of 95% of the worm, the average Insect population 144 heads / strain. Love tree stalks are all eaten light, like burning, seriously affecting the growth of tree vigor. After the pest disaster, it has cost more than 10,000 yuan to mobilize more than 3,500 people to dig pupae. In the severely affected 978 mu of forest, a total of 1287 kilograms of pupae were excavated, and the number of pupae per square meter was as high as 40. The pest outbreak Huashan song so far is still rare. In order to comprehensively and economically manage this pest, we conducted a two-year continuous feeding observation and an inter-forest investigation since 1980, recording the life history and some biological habits of the pest. Now the preliminary findings are summarized below.
