| 中文摘要: |
| 草原毛虫Gynaephora spp.是严重危害青藏高原草地生态环境和畜牧业发展的重大害虫。为筛选能防治草原毛虫的天敌昆虫, 本研究测定了蠋蝽Arma chinensis成虫对门源草原毛虫G. menyuanensis 6龄幼虫的捕食能力, 以及持续捕食门源草原毛虫对蠋蝽生长和繁殖的影响, 以明确蠋蝽对草原毛虫的控害潜能。结果表明, 蠋蝽成虫对门源草原毛虫幼虫具有较强的捕食能力, 每日可捕食6龄幼虫(3 cm)1~2头。蠋蝽成虫连续捕食门源草原毛虫幼虫28 d仍保持存活和繁殖, 持续控害潜能较高。蠋蝽取食门源草原毛虫幼虫21 d内, 其捕食量无显著变化, 存活率在80%以上。本研究首次发现并证实了蠋蝽是能有效捕食门源草原毛虫幼虫的天敌, 结果为指导利用蠋蝽防治门源草原毛虫提供了重要参考依据。 |
| 英文摘要: |
| Gynaephora spp. poses a significant threat to the grassland ecological environment and the development of animal husbandry in the Qinghai-Xizang Plateau. To identify natural enemy insects that can biologically control Gynaephora spp., the present study assessed the predatory capacity of adult Arma chinensis against the sixth-instar larvae of G. menyuanensis and studied the effects of sustained feeding on the growth, development, and reproduction of A. chinensis, aiming to determine the potential of A. chinensis as a biological control agent for G. menyuanensis. The results demonstrated that A. chinensis adults can actively prey on G. menyuanensis larvae and showed high predation ability, with one adult consuming one to two sixth-instar larvae per day. Adult A.chinensis feeding on G. menyuanensis larvae for 28 days were able to survive and reproduce, indicating a high potential for sustainable pest control. There was no significant change in consumption, and the survival rate was more than 80% for A. chinensis adults feeding on G. menyuanensis larvae over a 21-day period. This study is the first to identify and confirm A. chinensis as a natural predator capable of effectively targeting G. menyuanensis larvae. These findings offer valuable insights for utilizing A. chinensis in the management of G. menyuanensis. |
