Bean weevils get a kick out of mates
By Susan Milius
The battle of the sexes turns out to be a literal description of the domestic life of the bean weevil, say British researchers.
These insects, Callosobruchus maculatus, breed in stored grain throughout the tropics. The male’s agenda apparently includes reducing the chances that a female will mate with any weevil after she has mated him, say Helen S. Crudgington and Mike T. Siva-Jothy of the University of Sheffield in England.
