Genetics of cuticular hydrocarbon differences between males of the parasitoid wasps Nasonia giraulti and Nasonia vitripennis [PDF]
Heredity, 2010 Many insects rely on cuticular hydrocarbons (CHCs) as major recognition signals between individuals. Previous research on the genetics of CHCs has focused on Drosophila in which the roles of three desaturases and one elongase were highlighted. Comparable studies in other insect taxa have not been conducted so far.

The genus Nasonia belongs to a large and diverse group of insects the parasitoid wasps. Adult parasitoid wasps are free-living and lay their eggs in or on various life stages of arthropods (e.g., insects, ticks, mites). Parasitoids include more species beneficial to humans than any other insect group.

Reproductive strategies under multiparasitism in natural populations of the parasitoid wasp Nasonia (Hymenoptera) [PDF]
Journal of Evolutionary Biology, 2009 Parasitoid Nasonia wasps adjust their progeny sex ratio to the presence of conspecifics to optimize their fitness. Another trait under female control is the induction of offspring diapause.

Early memory in the parasitoid wasp Nasonia vitripennis
Journal of Comparative Physiology A, 2015We studied early memory in Nasonia vitripennis, a parasitoid of fly pupae and emerging model organism for ecological questions in the context of learning. After associative training consisting of one drilling experience in a host in the presence of cinnamon, females showed a preference to cinnamon for at least 24 h.

Abstract The species of the genus Nasonia possess qualities that make them excellent candidates for genetic and genomic studies. To increase the wealth of genomic resources for the genus we constructed publicly available bacterial artificial chromosome (BAC) libraries for

PATTERNS OF SPERM COMPETITION INNASONIA VITRIPENNIS
Canadian Journal of Genetics and Cytology, 1974Females of the parasitic wasp, Nasonia vitripennis Walker, were generally nonreceptive after the initial copulation. But if they were inseminated twice, once by each of two virgin males in quick succession, they seldom retained for utilization any sperm from the second mate.

A defensin antimicrobial peptide from the venoms of Nasonia vitripennis
Toxicon, 2010Although many antimicrobial components (i.e. antimicrobial peptides) have been found in many social Hymenoptera venoms, no antimicrobial compound is purified and characterized from parasitic Hymenoptera. From the venoms of the ectoparasitic wasp, Nasonia vitripennis, a defensin-like antimicrobial peptide named defensin-NV was purified and characterized.

The Paternal-Sex-Ratio Chromosome of Nasonia
The American Naturalist, 1991Paternal sex ratio (PSR) is a supernumerary chromosome that is transmitted through sperm to fertilized eggs and then gains a transmission advantage by causing supercondensation of the paternal chromosomes (except itself). Because of haplodiploidy, this converts diploid females into haploid (PSR) males.

Structure of the Micropyle in Eggs of Nasonia vitripennis
Nature, 1962IN insects a micropyle is formed at the anterior pole of the egg and often has a very complicated structure. Sometimes it is a single pore or it may consist of numerous canals grouped together. The formation of the micropyle is due to a number of follicle cells or nurse cells having protoplasmic prolongations towards the egg, around which the chorion ...
