摘要/Abstract

摘要： 为明确上海城市绿化植物中常见刺蛾的种间关系，定量研究了黄刺蛾、桑褐刺蛾、丽绿刺蛾及褐边绿刺蛾在营养、时间、空间资源序列上的生态位指数。结果表明：褐边绿刺蛾比其它刺蛾能较广泛地利用寄主资源，生态位宽度指数为0.5447；黄刺蛾、桑褐刺蛾在时间序列上占有较大优势，生态位宽度指数分别为0.4304和0.4415；而黄刺蛾的茧则在空间资源利用中优于其它刺蛾，生态位宽度指数为0.5441。在种间，桑褐刺蛾与丽绿刺蛾利用营养资源较为接近，其生态位重叠指数(2.6647)、生态位相似比例(0.5199)和种间竞争系数(0.7015)均高于其它共存种类；黄刺蛾和桑褐刺蛾利用时间资源较相似，生态位相似比例和种间竞争系数分别为0.4846、0.5222；而桑褐刺蛾和褐边绿刺蛾则在空间资源利用中较为接近，其生态位重叠指数(2.7495)、生态位相似比例(0.9165)和种间竞争系数(0.9959)在共存种间均为最高。

Abstract: To understand the interspecies relationships among common Limacodidae species on Shanghai green belt plants, the niche breadth, niche overlap, niche similarity, and interspecies competition of Cnidocampa flavescens, Setora postornata, Parasa lepida and Parasa consocia were studied in trophic, temporal, and spatial resources series. The results showed that P. consocia could use more host resources than other three species, and its niche breadth index was 0.5447. C. flavescens and S. postornata occupied more time resources, with the niche breadth index being 0.4304 and 0.4415, respectively. C. flavescens cocoons manifested the greatest spatial resources predominance, and the niche breadth index was 0.5441. As for the interspecies relationships, S. postornata and P. lepida were more adjacent in the utilization of trophic resources, and the indices of their niche overlap (2.6647), niche similarity (0.5199) and interspecies competition (0.7015) were all higher than those of other co-existing species. C. flavescens and S. postornata were more similar in using time resources, with the niche overlap and interspecies competition indices being 0.4846 and 0.5222, respectively, while S. postornata and P. consocia were more adjacent in the utilization of spatial resources, and had the highest indices of niche overlap (2.7495), niche similarity (0.9165), and interspecies competition (0.9959).
