摘要 采用室内饲养与野外试验的方法明确了柞栎象(Curculio dentipes)的生活史和生物学特性。结果表明:柞栎象在吉林地区1 a发生1代,以当年老熟幼虫和由上1 a越冬幼虫羽化出的成虫在地下土室内越冬。柞栎象越冬幼虫在土壤中存在明显的垂直分布格局,越冬幼虫集中分布在0~20 cm土层越冬,占全部越冬幼虫的94.32%。柞栎象成虫通过沿树干爬行和短距离飞翔上树。柞栎象幼虫出果时间主要集中在9月中下旬,占出果幼虫总数的92.71%。 Indoor rearing and field experiments were used to ascertain the life cycle of Curculio dentipes,and elucidate its biological characteristics.The life cycle of C.dentipes is one generation in one year,within-year matured larvae and adults emerged from last-year overwinter in soil cells.Overwintered larvae shows obvious vertical distribution in soils,and majority of overwintered larvae were distributed in soil layer in0-20cm,accounting for94.32%of total overwintered larvae.The adults of C.dentipes arrive crowns by climbing along trunks or flying.The exited time of larvae of C.dentipes from acorns mainly focus on early and medium September,accounting for92.71%of total larvae exited from acorns.
