Virus Like Particles

Virus-like particles have been found in specific regions of the reproductive tracts of three different braconid wasps, all parasitoids of the tobacco budworm, Heliothis virescens. The particles are nuclear in origin, and Feulgen cytochemistry of particulate fluid in the calyx and oviducts of one species has revealed the presence of DNA. On the basis of apparent structural homologies, it is suggested that the parasitoid particles are related to baculoviruses.

Virus Like Particles

Virus-like particles have been found in the female reproductive tracts of all Apanteles spp. thus far examined. Particles generally consist of putative baculovirus-like nucleocapsids which are enveloped singly or as groups within nuclei of calyx epithelial cells. Enveloped particles are injected into host caterpillars during oviposition. Subsequently, particle nucleocapsids appear in the cytoplasm of many host cells, and appear to be uncoated at nuclear pores.

AbstractParasitoid wasps inflict widespread death upon the insect world. Hundreds of thousands of parasitoid wasp species kill a vast range of insect species. Insects have evolved defensive responses to the threat of wasps, some cellular and some behavioral. Here we find an unexpected response of adult Drosophila to the presence of certain parasitoid wasps: accelerated mating behavior. Flies exposed to certain wasp species begin mating more quickly. The effect is mediated via changes in the behavior of the female fly and depends on visual perception. The sight of wasps induces the dramatic upregulation in the fly nervous system of a gene that encodes a 41-amino acid micropeptide. Mutational analysis reveals that the gene is essential to the behavioral response of the fly. Our work provides a foundation for further exploration of how the activation of visual circuits by the sight of a wasp alters both sexual behavior and gene expression.
