Problems solved by technology

[0003] At present, the scientific research work on B. yunnanensis is relatively weak, and the results are relatively few. The patent related to B. yunnanensis is only "a tree species and screening method for mixed forest species resistant to B. yunnanensis based on olfactory response. (CN201010546067)" and has nothing to do with the direct control of S. yunnanensis

Embodiment 1

[0016] A method for controlling the tip-cutting beetle of Yunnan, characterized in that it comprises the following steps:

[0017] A. From the end of February to the end of April every year, the damaged wilted and dying wood of Pine yunnanensis suffered from the eggs, larvae, and pupae of the Yunnan pine bark, that is, a large number of trees have been bred under the bark of the pine trunk. The eggs, larvae and pupae of the beetle form a large number of wormholes and creams of the beetle on the branches and trunks of the pine beetle due to the gathering of the beetle to feed and lay eggs, making Yunnan The crown of the pine tree loses water and the trees are in a wilting state, and the crown of the pine tree is completely dehydrated, green and wilted, and the trees are about to die.

[0018] B. Then, from late May to mid-July of the same year, the remaining wilted and dying trees of Pinus yunnanensis damaged by the eggs, larvae and pupae of bark beetle in the area after the fi...

Abstract

The invention provides a method for controlling Yunnan tip-cut bark beetles. The method comprises the steps that in the last ten days of February to the last ten days of April every year, victim wilting wood and dying wood of pinus yunnanensis, which are suffered from invasion of the eggs and larvas of the Yunnan tip-cut bark beetles are cut down; in the last ten days of May to the middle ten days of July in the same year, the victim wilting wood and the dying wood of pinus yunnanensis, which are suffered from invasion of the eggs and larvas of the Yunnan tip-cut bark beetles in the first cutting-down area in the A step are cut down for the second time. Accordingly, the harm, diffusion and spreading of the Yunnan tip-cut bark beetles can be effectively restrained. The method for controlling the Yunnan tip-cut bark beetles is simplest, most convenient and most obvious in effect.

Description

technical field [0001] The invention relates to a method for controlling the tip-cutting beetle in Yunnan, belonging to the technical field of pest control. Background technique [0002] S.yunnanensis Tomicus yunnanensis Kirkendall & Faccoli sp.n. (Curculionidae, Scolytinae) is a major tree borer pest in Yunnan pine planting areas. On July 9, 2008, Norwegian scientist Lawrence R. Kirkendall, Italian scientist Massimo Faccoli, and Professor Ye Hui from Yunnan University jointly published this species in "ZOOTAXA". In Guizhou and other provinces and autonomous regions, the cumulative area of ​​damage has exceeded one million mu, and there is a trend of spreading and spreading year by year. Any wilting wood of Pine yunnanensis caused by the yunnanensis beetle will inevitably transform into dying wood until the plant dies completely, which has become a "cancer" of pine yunnanensis in Southwest my country. The harm, spread and spreading method of beetle to Yunnan pine. [000...
