| 红铃虫甲腹茧蜂Chelonus pectinophorae是一种跨卵-幼虫期的寄生蜂。为有效挖掘该寄生蜂的生防潜能, 使其能够应用于田间生产, 本研究借助录像设备观察并分析了其生物节律和寄生行为。结果表明, 红铃虫甲腹茧蜂羽化期约6 d, 70%个体集中在前3 d羽化, 第1天雄蜂的羽化率显著高于雌蜂, 90%以上蜂茧在6:00-12:00羽化。雌雄成虫5:00-19:00均可活动, 求偶交配集中在7:00-9:00, 雌成虫产卵高峰为9:00-14:00。红铃虫甲腹茧蜂寄生行为可分为搜寻和识别寄主、刺探产卵、清洁梳理3个阶段。单头红铃虫甲腹茧蜂可连续产卵25~70次, 平均单次产卵时间20 s。甲腹茧蜂老熟幼虫体长约4 mm, 自寄主前胸一侧钻出后取食寄主虫体, 直至只剩头壳。红铃虫幼虫被寄生后, 2~4龄幼虫的体长和体重显著低于未寄生幼虫。本研究为红铃虫甲腹茧蜂的人工扩繁和田间应用提供科学理论依据。 |
| 英文摘要: |
| Chelonus pectinophorae is an egg-larval parasitoid of the pink bollworm (Pectinophora gossypiella). To better explore its biocontrol potential and promote its field application, the biological rhythms and parasitic behaviors of C.pectinophorae were observed and analyzed using continuous video recording. Results indicated that the eclosion period of C.pectinophorae lasted approximately six days, with 70% of individuals emerging within the first three days. The eclosion rate of males on the first day was significantly higher than that of females, and over 90% of adults emerged between 6:00 and 12:00. Both male and female adults were active from 5:00 to 19:00, with courtship and mating primarily occurring between 7:00 and 9:00, and oviposition peaking from 9:00 to 14:00. The parasitic process consisted of three main stages: host searching and recognition, probing and oviposition, and post-oviposition grooming. A single female C.pectinophorae could oviposit 25-70 times, with an average oviposition duration of 20 seconds per event. Mature larvae were approximately 4 mm long and emerged from the host’s prothorax, feeding externally on host tissues until only the head capsule remained. After parasitism, the body length and weight of 2th-4th instar pink bollworm larvae were significantly lower than those of unparasitized individuals. This study clarifies the developmental and behavioral patterns of C.pectinophorae and provides a theoretical basis for its artificial propagation and potential use in the biological control of pink bollworm infestations. |
