| Abstract: | The biological characteristics of Micromelalopha troglodyta,which is an important poplar leaf-eating pest in Dongting Lake area,were studied during 2007—2009.Results showed that M.troglodyta developed 7~8 generations a year in this area and lived through the winter in litter layer,porous shallow soil layer or crack in the form of pupae.The mean stages from 1 st to 7 th generations were 39d,28d,26d,23d,25d,29d,32d respectively.And the eclosion peak seasons of overwintering generation,1st~6th generations and seventh-generation were early-middle April,mid May,early-middle June,early-middle July,early August,late August,middle-late September and late October respectively.M.troglodyta in 1st~3rd generation developed relatively uniform and the generations overlapping after fourth-generation was more complicated. |
