中文摘要：
芦笋木蠹蛾Isoceras sibirica(Alpheraky)为芦笋(Asparagus officinalis (L.))上的一种蛀茎性害虫。试验结果表明，采用50％辛硫磷乳油300倍液在芦笋茎基部给药（5月中旬至6月中旬）为该虫的最佳化学防治方法，相对防治效果为92.5％，在所有处理中其加权Borda值最高（2.9）。调整芦笋播期，可使定植当年最易受害的笋苗免于虫害。
英文摘要： Isoceras sibirica(Alpheraky)is a serious stem borer of Asparagus officinalis (L.).The experimental results showed that applying phonix 50% (EC) of 300×liquid at the base of asparagus stems in midMay to midJune was the optimum method to control I. sibirica larvae. Its control efficency could reach 92.5% and the weighted Borda value was the hightest（2.9）in all of the treatments tested. The damage of wood moth to the asparagus seedlings (one aged seedlings) could be avoided by adjusting the sowing date.
