GENETIC VARIATION FOR THE SEX RATIO IN NASONIA VITRIPENNIS [PDF]

Genetics, 1985
ABSTRACT We detected genetic variation for the sex ratio in the parasitoid wasp Nasonia vitripennis by analysis of inbred lines and with an artificial selection experiment. Sex ratios differed significantly among five independently isolated lines. Furthermore, sex ratio in broods produced by single females in single hosts shifted from 80-

The costs and benefits of multiple mating in a mostly monandrous wasp [PDF]

, 2015
Funding: NERC DTGThe taxonomically widespread nature of polyandry remains a puzzle. Much of the empirical work regarding the costs and benefits of multiple mating to females has, for obvious reasons, relied on species that are already highly polyandrous.

The transcriptomic basis of post-mating responses in females of the parasitic wasp Nasonia vitripennis [PDF]

, 2012
Mating in insects influences suites of behavioural and physiological changes in females. These changes can include key female traits such as dispersal, foraging, oviposition and female remating or receptivity.

Exploring the Potential of Venom from Nasonia vitripennis as Therapeutic Agent with High-Throughput Screening Tools

Toxins, 2015
The venom from the ectoparasitoid wasp Nasonia vitripennis (Hymenoptera: Pteromalidae) contains at least 80 different proteins and possibly even more peptides or other small chemical compounds, demonstrating its appealing therapeutic application.

Beyond sex allocation : the role of mating systems in sexual selection in parasitoid wasps [PDF]

, 2014
Funding: UK NERC Doctoral Training GrantDespite the diverse array of mating systems and life histories which characterise the parasitic Hymenoptera, sexual selection and sexual conflict in this taxon have been somewhat overlooked.

A novel host-parasitoid association: first record of Nasonia vitripennis (Walker, 1836) (Hymenoptera: Pteromalidae) parasitizing Microcerella halli (Engel, 1931) (Diptera: Sarcophagidae) in southern Brazil

EntomoBrasilis
Records of trophic associations between sarcophagid flies (Diptera: Sarcophagidae) and their natural enemies remain scarce, limiting ecological and forensic interpretations of decomposition systems.

Cytoplasmic incompatibility and bacterial density in Nasonia vitripennis. [PDF]

Genetics, 1993
Abstract Cytoplasmically (maternally) inherited bacteria that cause reproductive incompatibility between strains are widespread among insects. In the parasitoid wasp Nasonia, incompatibility results in improper condensation and fragmentation of the paternal chromosomes in fertilized eggs.
