Lipogenesis in an adult parasitic wasp.
The goal of this study was to determine the extent of lipogenesis in the parasitoid Eupelmus vuilletti (Hymenoptera: Eupelmidae). Carbohydrate and lipid metabolism were followed in glucose-fed and starved females over 3 days. Fed females increased their glycogen level, while maintaining their lipid level. Starved females used most of their glycogen, while maintaining their lipid level too. Thus...
متن کاملGenetically Nontransmissible Nuclear Damage Induced by Ultraviolet Radiation in the Wasp Habrobracon.
N Habrobracon, unfertilized eggs develop normally and become haploid males; I fertilized eggs become diploid females. It has been observed that when newlylaid eggs from virgin females are exposed to ultraviolet radiation on the nuclear (convex) surfaces, embryo hatchability decreases as the exposure time is increased (VON BORSTEL and MOSER 1956; VON BORSTEL and WOLFF 1955). Most of the deaths o...

متن کاملComplementary Sex Determination in the Parasitic Wasp Diachasmimorpha longicaudata
We studied the sex determination in Diachasmimorpha longicaudata, a parasitoid braconid wasp widely used as biological control agent of fruit pest tephritid flies. We tested the complementary sex determination hypothesis (CSD) known in at least 60 species of Hymenoptera. According to CSD, male or female development depends on the allelic composition of one sex locus (single-locus CSD) or multip...
متن کاملThe physiological costs of being small in a parasitic wasp
Knowledge of the relationship between body size and fitness is essential in many models of parasitoid evolutionary ecology. One clear point emerging from previous studies is that the relationship between size and fitness can depend strongly (qualitatively and quantitatively) on the environment in which it is measured. Our results show that, in the parasitoid wasp Nasonia vitripennis, the relati...
