The reproductive organs of Bruchus quadrimaculatus Fabr.Abstract:
The reproductive organs of Bruchus quadrimaculatus Fabr., and B. (Callosobruchus) chinensis L., including histology are described in detail. The role of the different parts of the male and female copulatory apparatus is discussed and the physical composition and function of the secretions of the accessory glands are indicated. The specific differences in the structure of the genitalia of the two species are shown.read more

Biology and phylogeny of the Cassidinae Gyllenhal sensu lato (tortoise and leaf-mining beetles) (Coleoptera: Chrysomelidae)
TL;DR: The biological account and phylogenetic results provide an opportunity for identifying some general trends and major innovations in the evolutionary history of Cassidinae.

Why do male Callosobruchus maculatus beetles inseminate so many sperm
TL;DR: The results indicate that males transferring large numbers of sperm during copulation have a two-fold advantage at fertilization; they are more effective at preempting previously stored sperm and they are likely to father more offspring by delaying the time of female remating.

Female fitness consequences of male harassment and copulation in seed beetles, Callosobruchus maculatus
TL;DR: When females were both harassed by and could remate with more than one male, they had lower lifetime reproductive rates and reduced life span relative to monandrous females, indicating that the direct benefits of multiple mating do not compensate for the costs.
Journal ArticleDOI
Evolution of male and female genitalia following release from sexual selection
TL;DR: It is argued that further advances in the study of genital coevolution will require a much more detailed understanding of the functions of male and female genital traits, and the evolution of static allometry in response to variation in sexual selection opportunity.

Comparative morphology of the internal reproductive system of the Chrysomelidae (Coleoptera)
TL;DR: A great number of studies dealing with the structure of various facets of the Coleoptera system, such as morphology, embryology, physiology, ecology, etc., have been concisely summarised.
