Gypsy moth parasitoids in the declining outbreak in Lithuania

摘要: A 3 year study was conducted on the parasitoids of gypsy moth larvae in two reducing outbreak areas Lithuania. Overall parasitism 25.0 ± 2.0% first post-culmination significantly lower than 36.3 1.4 and 35.2 1.4% subsequent years. When analysed terms life stage at which host collected, total over years constantly increasing from 3.1 0.8 to 72.5 2.9% sixth instar. Parasetigena silvestris R.-D. dominated causing 48.7 1.5% 16.7 0.6% larval mortality preferably late instars. Phobocampe disparis Vier, contributed 21.9 1.2% 7.5 0.5% recovering early instar larvae. Meteorus pulchricornis Wes. parasitized 4.3 1.5 0.2% a few Apanteles species provided 2.8 1.0 mortality. The Lithuania reported act as for Rogas sp. (Hym., Braconidae) Siphona boreata Mes. (Dipt., Tachinidae).
