Abstract:Ficus microcarpa is a monecious species which is widely distributed in Asian tropical and subtropical regions. Except for the species of specific pollinating fig wasps, the figs are also exploited by multiple non-pollinating fig wasps. These non-pollinating fig wasps visit figs to lay eggs in different fig developmental phases, and have different effects on the seed and pollinator production. Odontofroggatia galili is a main non-pollinating fig wasp in the figs of F. microcarpa. The occurrence regularity of O. galili were studied from 2012 to 2013. The results showed that both female and male O. galili had wings, and the males were pleomorphic in body size. O. galili laid eggs on the figs in pre-female phase, and was able to make galls independently. At Xishuangbanna region, the period of development from eggs to adults was 31~38 days in warm-dry season and rainy season, and 58~72 days in cold-dry season. The adults emerged in male phase of figs. Males firstly left fig cavity and waited for the females around the ostiole. Once the female came out, males caught the female for copulation. In general, female and male wasps only mated one time. There was strong fighting among males in order to compete mating chance, and large males were easy to win. The longevity of female adults was two days, and the males only survived one day. On F. microcarpa, 40% of the trees were exploited by O. galili, and the fig occupancy and the number of O. galili produced by a single fig showed significant differences among trees. In the original Xishuangbanna region, the pollinating fig wasp was main species, whereas O. galili showed a low occurrence frequency and the population size was small. However, O. galili had a high occurrence frequency and a significant larger population in the introduced Kunming city. The pollinating fig wasps were rarely reproduced when F. microcarpa was introduced to plant in high latitude and high altitude region, but the reproduction of O. galili was more successful. These results suggest that, O. galili, rather than the pollinating fig wasp, has adapted reproduction in high latitude and high altitude region.
