dc.description.abstractAgabus biguttatus and Agabus conspersus have been selected as a model in order to compare the seasonal variations of female reproductive system. Specimens were collected from a spring-stream from southern Iran between mid-spring 2003 to mid-Winter 2004. The female internal reproductive system of A. conspersus, showed no outstanding difference in different seasons when compared with A. biguttatus in regards to general shape and structure. The greatest difference was in the size and shape of bursa copulatrix. The bursa copulatrix (a part of female reproductive system) has a cuticular feature with some parallel lines on it in A. conspersus. However, the bursa copulatrix has a soft feature without any lines on it. In addition, by studying the reproductive systems in different seasons, two phases, developing and degenerative can be proposed for them. In developing phase (mature, ready for mating) the length and diameter of gonads and accessory glands were larger than in degenerative phase. All the specimens collected in spring and summer demonstrate developing phase, while the autumn and winter specimens show the degenerative one.
