摘要
Acantholyda erythrocephala\%, a kind of destructire insect, is found recently in Shenyang, China. Its host tree is \%Pinus\% spp. especially \%Pinus tabulaeformis\% and \%P.densiflora\%. The injured branch, tip will be withered or even died. The harmful period of the larvae is about one month. There is one generation during a year in Shenyang area. Winter is passed as prepupae by making earth cells in the soil at the depth of 0～10cm. It can be controlled by many ways:set up closed forest; making conopy density be more than 0.7; digging out the forest soil in autumm, winter or early spring; cutting the larval nests and burning up; spraying 10% pyrethrum at 8000x ditution to the early instar larvae.
