| Abstract: | Sesia siningensis has one generation within two years in Qinghai. The larva eats trunk. Both male and female adults copulate only once during their lifetime. The ratio of female to male was about 1:1.The adults eclosion appears main and assistant time in a year. The factors of its occurrence related to the species of the tree, altitude and forest type etc. Harm intrudes from the lower to the upper. According to the characteristic, sex-attractant as the main control measurements should be used to control. |
