摘　　要：芦笋木蠹蛾Isoceras sibirica（Alpheraky）是危害芦笋的重要害虫。该虫在山西省运城市1年发生1代,以老熟幼虫在土中结薄茧越冬。翌年3-4月老熟幼虫由深土层上移至地表土壤结茧化蛹。4月中下旬为化蛹高峰。5月上中旬为蛹羽化高峰期。6月上旬为卵孵化高峰期。幼虫为害期为5月下旬至10月下旬。对该虫的形态、生活习性和发生规律作了描述和报道。lsoceras sibirica（Alpheraky） has one generation a year and overwinters as matured larvae in the soll in Yuncheng City, Shanxi Province. In March to April, the matured larvae move from deep soil layer towards surface and knit the cocoon and pupate. The mid-late April is the peak period for 1. sibirica to pupate and the early-mid May is the peak period for adult emergence. The damage period is in late May to late October. The morphology, habits and occurrence are describedr.
