【摘要】 松突圆蚧是我国一类进境植物检疫危险性病虫,为了探讨松突圆蚧病原真菌对蚧虫的防治效果,采用随机区组和完全随机试验设计,分别在广西博白林场和岑溪市两地,开展了不同季节的防治试验。试验结果表明:项目筛选的松突圆蚧病原真菌在林间对松突圆蚧能够取得良好的防治效果,试验死虫率达到80%以上,校正死虫率达到40%以上;在严重受灾地区其可控时间至少可达160多天;不同季节的防治效果存在一定差异,冬季和春季的防治效果好于夏季;尽管冬季干旱,夏季高温,但仍能有效控制松突圆蚧的虫口密度。更多还原

【Abstract】 Hemiberlesia pitysophila Takagi is a fatalnes plant diseases and insect pest of quarantined by the People’s Republic of China. For probe into the effect of prevention and cure on the insect pest of Hemiberlesia pitysophila Takagi pathogenic fungi, the prevention and cure tests in different season were done at Guangxi Bobai forestry farm and Cenxi, by the test design of random sections and complete random. Results showed that well effect of prevention and cure in woodland was gained by the Hemiberlesia pitysophila Takagi pathogenic fungi. The test death rate reached 80% upwards. Enemdation rate reached 40% upwards. Controllable period of time in the forest area of badly harm by Hemiberlesia pitysophila Takagi is 160d at least. There was difference of effect of prevention and cure in different season. The effect of prevention and cure in winter and in spring is better than that of in summer. In despite of drought in winter and high temperature in summer, the pest population density of Hemiberlesia pitysophila Takagi was controled effectively however.更多还原
