樟叶蜂在湖北1年发生3代,以老熟幼虫在土壤中越冬,3月中、下旬至5月中、下旬为发生为害期。幼虫从叶缘或近叶脉处开始取食,每隔15~16min排便1次;老熟幼虫具浓烈的松香味,并有假死性。采用冬季翻耕及用100亿孢子/g青虫菌菌粉700倍液喷药,能有效地控制樟叶蜂的发生。
Camphor leaf bee occurred in Hubei for 1 year 3 generations to mature larvae overwinter in the soil, mid-March, late to mid-May, late for the occurrence of harm. The larvae began feeding from the leaf margin or near the veins and detoxified every 15 to 16 minutes; the mature larvae had a strong rosin flavor and had a lethality.
