FIRST RECORD OF A BIG-HEADED FLY, EUDORYLAS ALTERNATUS (CRESSON) (DIPTERA: PIPUNCULIDAE), REARED FROM THE SUBFAMILY CICADELLINAE (HOMOPTERA: CICADELLIDAE), WITH AN OVERVIEW OF PIPUNCULID–HOST ASSOCIATIONS IN THE NEARCTIC REGION

Abstract

Eudorylas alternatus(Cresson) is recorded as a parasitoid of Cuerna striata(Walker) (Homoptera: Cicadellidae, Cicadellinae), providing the first known example of a big-headed fly parasitizing a cicadelline. Rearing methods and parasitism rates are discussed, and a summary of known Nearctic pipunculid–host associations is presented along with an overview of big-headed fly natural history.

Résumé
