Chutian Metropolis Daily, 5 June (Reporter Zhou Zhitao Wangjun correspondent Guo Yanhua) a brick shot to death, one foot down to the death, can be killed and never crippled, in order to eliminate the street trees are about to enter the breeding period of the tianniu, the garden personnel are also fierce. According to the insect situation forecast of the Research Institute, the recent is the frequent season of adult activities of tianniu, and adult tianniu will come out to mate and eat the epidermis, which seriously threatens the health of street trees.
According to reports, the Qingshan District Landscaping Team seized this opportunity and began to manually capture adult Tianniu. In the early stage, the greening team used self-made tools to catch Tianniu larvae with remarkable results, and now it is a favorable opportunity to seize the adult Tianniu in the bark mating activity, and further manual capture will further improve the insect control effect.
According to Jiang Nian, deputy captain of the greening team, after the emergence of the adult tianniu, if there is no killing during the mating period, then soon the adults will begin to eat the bark, and then drill into the center of the tree to lay eggs, and the egg stage is about 10 days, that is, the hatching of the larvae begins. Grabbing and killing the celestial cow during the mating period is equivalent to directly killing the mother, which can not only save the tree from the injury of nibbling, but also avoid the troubles caused by the late spawning and hatching.
