Description of the Immature Stages of Paracantha gentilis (Diptera: Tephritidae)

Ann. Entomol. Soc. Am. 83(2): 220-229 (1990) ABSTRACT Descriptions are provided of the egg, larvae, and puparium of Paracantha gentilis Hering, a native, stenophagous tephritid which infests the capitula of thistles. Detailed examination of larvae led to the discovery of a median oral lobe between the mouth hooks. This is the first structure of this kind described for Tephritidae. Two sensory s...

Immature Stages of Development in the Parasitoid Wasp, Diachasmimorpha longicaudata

The morphological changes experienced during the immature stages of the solitary parasitoid Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae: Opiinae) were studied. This natural enemy of several species of tephritid fruit flies is widely used in biological control strategies. Immature stages are poorly understood in endoparasitoids because they exist within the host. In the prese...
