Sperm ultrastructure and spermiogenesis of Coniopterygidae (Neuroptera, Insecta).
The spermiogenesis and the sperm ultrastructure of several species of Coniopterygidae have been examined. The spermatozoa consist of a three-layered acrosome, an elongated elliptical nucleus, a long flagellum provided with a 9+9+3 axoneme and two mitochondrial derivatives. No accessory bodies were observed. The axoneme exhibits accessory microtubules provided with 13, rather than 16, protofilam...
متن کاملThree new species of Osmylus Latreille from China (Neuroptera, Osmylidae)
Three new species of Osmylus Latreille are described from China: Osmylus maoershanicola sp. n., Osmylus shaanxiensis sp. n. and Osmylus angustimarginatus sp. n. These new species are distinguishable from other related species by the shape of the 9(th) tergite of both sexes, as well as the shape of gonarcus, mediuncus and spermatheca. A key is given to differentiate Palaearctic and Oriental spec...

15 صفحه اولThe effect of thermal stress on the mating behavior of three Drosophila species.
Selection may act on the weakest link in fitness to change how a species adapts to an environmental stress. For many species, this limitation may be reproduction. After adult Drosophila melanogaster, Drosophila simulans, and Drosophila mojavensis males were exposed to varying levels of thermal stress well below those that endanger life, courtship and mating frequency declined. The regression co...
متن کاملMating patterns and post-mating isolation in three cryptic species of the Engystomops petersi species complex
Determining the extent of reproductive isolation in cryptic species with dynamic geographic ranges can yield important insights into the processes that generate and maintain genetic divergence in the absence of severe geographic barriers. We studied mating patterns, propensity to hybridize in nature and subsequent fertilization rates, as well as survival and development of hybrid F1 offspring f...
