- Mating in the aphid parasitoid, Aphidius ervi, is mediated by sex pheromones. Virgin females produce pheromones that stimulate both upwind flight and elicit close-range courtship behavior by males. Field studies and laboratory bioassays demonstrated that time of day and adult age affect both the emission of, and receptivity to, the sex pheromones. In contrast, mating affected female pheromone production, but not male responsiveness.
