Sperm competition favors large, costly ejaculates, and theory predicts the evolution of
allocation strategies that enable males to plastically tailor ejaculate expenditure to sperm …

In insects, seminal fluid molecules (SFMs) influence female post-mating phenotypes that
affect reproductive success including egg development, sperm use, mating behavior …

Seminal fluid proteins (SFPs) exert potent effects on male and female fitness. Rapidly
evolving and molecularly diverse, they derive from multiple male secretory cells and tissues …

The ability of female insects to retain and use sperm for days, months, or even years after
mating requires specialized storage organs in the reproductive tract. In most orders, these …

Environmental stressors can impact the basic biology and applications of host-microbe
symbioses. For example, Wolbachia symbiont densities and cytoplasmic incompatibility (CI) …
