Parasites and pathogens, including genomic parasites, are ubiquitous and key agents in shaping insect mating systems. Theoretically, parasites and parasitoids can maintain genetic variation in traits involved in mate choice, and selective pressures by parasitoids are known to cause marked shifts in the mating signals of several species. Recent research has focused on insect immune defence, and the way in which investment in immunity is traded off against reproductive effort. Individuals with more robust immunity are likely to have higher mating success or more highly elaborate ornaments; in...
