摘要: [目的]研究兰氏原绒茧蜂的生物学特性,为竹弯茎野螟的生物防治提供科学依据。[方法]采用野外调查与室内试验相结合的方法,对兰氏原绒茧蜂的寄生生物学特性进行研究。[结果]兰氏原绒茧蜂成虫羽化主要发生在上午8:00-10:00,且羽化当天即可交配、产卵;该成虫可兼营两性生殖和孤雌生殖,但孤雌生殖未见雌性后代;在16~32℃范围内,16℃的成虫发育历期最长为6.65±0.24天,以10%蜂蜜水作为补充营养成虫发育历期则增加到13.35±0.37天。[结论]兰氏原绒茧蜂的寄生率随寄主发生代数增加而增加,且主要选择3-4龄幼虫期寄主寄生。在一定温度范围内,兰氏原绒茧蜂的发育历期随温度升高而降低,以10%蜂蜜水作为补充营养可显著延长成虫寿命。

Abstract: [Objective] Protapanteles lamborni is a dominant larval parasitoid of Crypsiptya coclesalis. Understanding of biological habits of P. lamborni would provide the fundamental information for biological control of C. coclesalis.[Method] In this paper, the field investigation and laboratory tests were used to study the parasitic characteristics of P. lamborni.[Result] Result showed that adults of P. lamborni mainly emerged between 8:00 and 10:00 am, so that they could copulate and lay eggs on the same day. The adult could perform both amphigony and arrhenotoky. In the range of 16℃ to 32℃, the adult development period at 16℃ lasted maximally for 6.65±0.24 days, however it could be 13.35±0.37 days if 10% honey solution was added as supplementary nutrition.[Conclusion] P. lamborni had an increasing parasitic rate with generations of the host of C.codesalis, and it mainly parasitized the third or fourth instar larvae of C. codesalis. Within a certain range of temperature, the developmental duration of P. lamborni decreased with the increase in temperature, but the adults could extend their longevity significantly if being supplied with 10% honey solution as supplementary nutrition.
