Kinky sex and suicidal mating behaviour in Aphidoletes aphidimyza
2003
Lenteren, J.C. van | Schettino, M.
Mass production of Aphidoletes aphidimyza is often difficult because usually a large proportion of the females are infertile or lay very few eggs. By accident we found that 'dirty' rearing cages containing spider webs resulted in a much higher reproduction. When we analysed this problem, it became clear that A. aphidimyza use spider webs for mating. After a female has landed in a spider web she starts to emit a pheromone. Males react to this pheromone, land in the spider web, move to the female and mate. Both males and females will leave the spider web after mating. We discuss why A. aphidimyza uses spider webs for mating even though it runs the risk of being discovered and devoured by the spider
