Predatory enemies of Matsucoccus matsumurae and their population dynamics

Abstract: Investigation on Changle Forest Farm of Yuhang City , Zhejiang Province during 1982 ~ 1985 indicated that there were 13 families, 31 species of predatory enemies on M .matsumurae .Seven of them were reported at first which belong to ants and spiders.Ladybugs and ants were the most important predatory enemies in percentage, which contain 35 %~ 51 % and 30 %~35 % separately .Exochomus monglo , Sticholotis punctatus , Harmonia axyridis and Harmonia obscurosignata had a bigger population respectively .When the density of M .matsumutae increased , the number of ladybeetle increased , and in low density of M .matsumuae , the number of mite and pentatomid increased .When M .matsumurae and Cinara pinitabulaeformis developed in Pinus massoniana forests at same time , the number of ant , mite and pentatomid increased but ladybeetle and chrysopa decreased .
