Most parasitoids of aphids are small wasps belonging to the families Braconidae or Aphelinidae. However, some dipteran parasitoids are also known to use aphids as hosts. We describe and give life-history information on a new species of aphid parasitoid, Endaphis fugitiva Gagné and Muratori, found to parasitize the banana aphid, Pentalonia nigronervosa Coquerel, the vector of banana bunchy top virus. Field and laboratory observations show that fly eggs are laid on the leaves near an aphid colony, the newly hatched fly larvae search for hosts while crawling on the leaf, and then penetrate the aphid between the legs and thorax. They develop as koinobiont endoparasitoids, and eventually emerge from the aphid anus and fall to the ground to pupate in the soil. We provide data relevant to parasitoid rearing on patterns of emergence, adult longevity, and effects of pupation substrate on adult emergence rate, and we discuss the potential of this new species to contribute to the biocontrol of banana aphid in Hawaii.
