梨小食心虫越冬位置对其幼虫存活的影响
Influence of Overwintering Site on Larval Survival of Grapholitha molesta Busck
摘要
Abstract
To clarify the impact of overwintering site in orchards on overwintering larval survival rate of Grapholitha molesta Busck,six typical orchards in Shandong Province including Caishi,Taian,Feicheng 1, Feicheng 2,Guangrao and Laiwu were selected for systematic investigation and analysis.The collected larvae were took back to observe their survival and compare the overwintering survival rate on different positions of trunk.The results showed that there were significant differences in the overwintering larval survival rate of G. molesta in different directions in the same orchards and highest overwintering larval survival rate appeared in the west side.The overwintering larval survival rate in shady side and sunny side were significant differences in Guangrao orchards,and there was no difference in other orchards.The overwintering larval survival rate in lower parts of fruit tree was the highest,and there was no difference between main trunk,bough and the lateral branches.Great differences were found in the overwintering survival rate of G.molesta between different orchards.关键词
