摘  要:对聚果榕五种非传粉小蜂的产卵行为进行了详细的观察,并对金小蜂Apocrypta westwoodi和长尾小蜂Platyneura agarensis的食性进行了深入研究。聚果榕上的5种非传粉小蜂的产卵顺序依次为,P.testeace,Apoc-ryptasp.,P.mayri,A.westwoodi,P.agraensis。在榕果的生长发育期内适合P.testeace,P.mayri和P.agraensis产卵的时间分别约为6 d,11 d,22 d。Apocryptasp.和A.westwoodi分别紧随其寄主P.testeace和P.mayri产卵,适合这两种小蜂产卵的时间依次约为6 d,33 d。Platyneura属的3种长尾小蜂的产卵姿势比较相似,Apocrypta属的2种金小蜂产卵姿势也是相似的。金小蜂A.westwoodi仅寄生于长尾小蜂P.mayri,并不寄生于传粉榕小蜂Ceratosolen fusciceps。长尾小蜂P.agraensis是传粉榕小蜂的寄生者,并非植食性造瘿者。The oviposition behavior of the five nonpollinating fig wasp species in the figs of Ficus racemosa L. was observed. Their ovipositing sequence on the F. racemosa was Platyneura testeace, Apocrypta sp. , P. mayri, A. westwoodi, P. agraensis. P. testeace, P. mayri and P. agraensis could oviposit about 6 days, 11 days and 22 days in succession during the growth of the fig fruits, respectively. Whereas Apocrypta sp. and A. westwoodi which followed their hosts P. testeace and P. mayri could continue for about 6 days and 33 days, respectively. The three species of Platyneura showed similar postures when they were ovipositing, and the two species of Apocrypta also presented similar postures. A. westwoodi did not parasitize the nonpollinating fig wasp P. mayr/but only prarasitized the pollinating fig wasp Ceratosolen fusciceps. P. agraensis parasitized the pollinating fig wasp C. fusciceps and it was not the wart-malar.
