摘要: 通过野外观察和室内养殖,对西北豆芫菁Epicauta sibirica(Pallas, 1773)成虫的取食偏好与交配行为进行了观察和分析,结果发现:1)西北豆芫菁成虫喜食大豆和马铃薯的叶片;2)西北豆芫菁成虫的交配行为包括求偶和交尾2个阶段.求偶过程会反复多次,求偶行为持续时间平均为(9.60±1.78)min,间隔时间平均为(6.55±1.92)min.交尾过程中采用“一”字式姿势,交尾时段主要集中在8:00~13:00,交尾持续时间平均为(165.44±14.17)min.

Abstract: The feeding preference and mating behaviors of Epicauta sibirica(Pallas, 1773)were analyzed by observation indoors and in the field. Results showed: 1)Glycine max and Solanum tuberosum were the most preferred host plants for adult; 2)Mating behavior of E. sibirica included both courtship and copulation. The courtship behavior is repeated several times in one mating process. Courtship behavior lasted(9.60±1.78)min; the interval between the two behaviors lasted(6.55±1.92)min. The species assumes linear position in the copulation. The copulation behavior occurred at 8:00 to 13:00 mostly and lasted(165.44±14.17)min.

Key words: Epicauta sibirica, adult, feeding preference, courtship, copulation
