| Abstract: | The ovipositors of two whitefly parasitoids, Encarsia transvena and Eretmocerus mundus were examined using scanning and transmission electron microscopy. That of Encarsia is straight, has an apparently hard and sharply pointed upper valve, and appears well-suited to penetrating a hard substrate. That of Eretmocerus is curved, thick-walled, but has a blunt and apparently flexible tip. These features correlate well with what is known of the mode of oviposition and host feeding in the two taxa, with Encarsia and Eretmocerus ovipositing internally and externally respectively. |
