“…Gause was only able to produce cycles by periodic introductions of new animals. For a time this result was areepted as typical, but subsequent experiments on other organisms demonstrated that cycles in contained populations were possible (Utida, 1955;Huffaker, 1958;Flanders and Badgley, 1963;Burnett, 1964;Pimentel, Kagel, and Madden, 1963).…”

“…Callosobruchus spp. (bean beetles) have been used not only in studies of intraspecific and interspecific competition (e.g., Utida 1941Utida , 1953Fujii 1965) but also in studies of sexual conflict (e.g., Rönn et al 2006;Eady et al 2007;Arnqvist and Tuda 2010) and host-parasitoid interaction (e.g., Utida 1950Utida , 1955Tuda 1998). Two commonly studied species, C. chinensis and C. maculatus, are both worldwide pests.…”

Reproductive interference in laboratory experiments of interspecific competition

Many studies that have researched interspecific competition in Callosobruchus (bean beetles), Drosophila (fruit flies), and Tribolium (flour beetles) have considered the major drivers of interspecific competition to be interspecific resource competition and intraguild cannibalism. These competition drivers have a density‐dependent effect on the population dynamics. However, some studies have also detected a relative‐frequency‐dependent effect in the observed population dynamics. The most likely causal mechanism of this relative frequency dependence is reproductive interference, defined as any interspecific sexual interaction that damages female reproductive success. Reproductive interference has been overlooked by most laboratory studies in spite of the critical effect on the competition outcome. In this paper, I review laboratory studies of these insect genera from the perspective of reproductive interference and show that the reported results can be more reasonably interpreted by the joint action of reproductive interference and resource competition, including intraguild cannibalism. In addition, on the basis of results reported by a small number of related studies, I discuss the behavioral and evolutionary changes induced in those genera by reproductive interference.
