Abstract

Rearing of L. sericata and C. albiceps in pure cultures of a variety of densities, at four constant temperature regimes, demonstrated an inverse relationship between egg density and the total development (F(2,6) = 264.35 and F(2,6) = 71.87 For L. sericata and C. albiceps, respectively p < 0.05), survivorship (F(2,9) = 68.41; p < 0.001 forL. sericata and F(2,9) = 12.35; p < 0.05 for C. albiceps) and adult size (For L. sericata: males F(2,9) = 58.94 and females F(2,9) = 140.09. For C. albiceps: males F(2,9) = 43.62 and females F(2,9) = 167.99. In all cases p < 0.001) of both species. Addition of C. albiceps reduced the development time and survivorship of L. sericata at a variety of densities and proportions at 17 and 23 degrees C. While at 29 and 35 degrees C, a complete elimination of L. sericata was recorded. Neither egg density nor temperature has a significant effect on the sex ratio of the resulting adults. It seems that the interaction between these species is a highly asymmetric case of competition.

摘要

在四种恒温条件下，以不同密度对丝光绿蝇和白纹厕蝇进行纯培养，结果表明卵密度与这两种蝇类的总发育时间（丝光绿蝇：F(2,6) = 264.35；白纹厕蝇：F(2,6) = 71.87，p均< 0.05）、存活率（丝光绿蝇：F(2,9) = 68.41，p < 0.001；白纹厕蝇：F(2,9) = 12.35，p < 0.05）以及成虫大小（丝光绿蝇：雄性F(2,9) = 58.94，雌性F(2,9) = 140.09；白纹厕蝇：雄性F(2,9) = 43.62，雌性F(2,9) = 167.99，所有情况p均< 0.001）均呈负相关。添加白纹厕蝇会在17℃和23℃时，在不同密度和比例下缩短丝光绿蝇的发育时间并降低其存活率。而在29℃和35℃时，丝光绿蝇会被完全消灭。卵密度和温度对所产生成虫的性别比例均无显著影响。这两种蝇类之间的相互作用似乎是一种高度不对称的竞争情况。
