Description:

Larvae of Aphidoletes aphidimyza (Rondani) (Diptera: Cecidomyiidae) secrete an oviposition-deterring pheromone (ODP). In choice tests, females of A. aphidimyza laid significantly fewer eggs on Vicia faba L. plants infested with Aphis fabae Scopoli (Homoptera: Aphidoidea) that were previously exposed to conspecific third-instar larvae or a water extract of their ODP. A. aphidimyza females also laid fewer eggs on aphid-infested plants that were previously exposed to unfed first-instar larvae of Chrysopa oculata Say, Chrysopa perla (L.) or Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae), or second-instar larvae of Coccinella septempunctata L. (Coleoptera: Coccinellidae). However, the response to traces of C. carnea larvae was very weak.
