Do Wolbachia influence fecundity in Nasonia vitripennis? [PDF]

open access: yesHeredity, 2000
This paper reports the influence of a vertically transmitted symbiont, Wolbachia, on host fitness in the parasitic wasp, Nasonia vitripennis. We measured fecundities of uninfected strains and strains infected with either two Wolbachia variants (wAv,wBv) or one (wAv or wBv). Preliminary tests suggested that double-infected females produce more offspring

Early memory in the parasitoid wasp Nasonia vitripennis

Journal of Comparative Physiology A, 2015
We 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.

A method for parental RNA interference in the wasp Nasonia vitripennis

Nature Protocols, 2006
The wasp Nasonia vitripennis is emerging as a useful model organism in which to address a variety of biological questions, due, in part, to its ease of laboratory use, unique aspects of its biology and the sequencing of its genome. In order to take full advantage of the potential of this organism, methods for manipulating gene function are needed.

PATTERNS OF SPERM COMPETITION INNASONIA VITRIPENNIS

Canadian Journal of Genetics and Cytology, 1974
Females 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.

The effect of host species on diapause induction in Nasonia vitripennis

Journal of Insect Physiology, 1970
Abstract The ‘expression’ of the photoperiodic clock in the parasitic wasp, Nasonia vitripennis , is modified by the species of blowfly puparia used as host. With Sarcophaga barbata the life-span is short and fecundity low, but the ‘switch’ to the production of diapause larvae occurs after only 8 to 11 short-day cycles; the proportion of diapause ...

A defensin antimicrobial peptide from the venoms of Nasonia vitripennis

Toxicon, 2010
Although 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.

Associative Learning ofNasonia vitripennisWalker (Hymenoptera:Pteromalidae) to Methyldisulfanylmethane

Journal of Forensic Sciences, 2013
AbstractTraditional methods of volatile detection used by police typically consist of reliance on canine olfaction. However, dogs have some limitations such as cost of training and time of conditioning. The possibility of using parasitic wasps for detecting explosives and narcotics has been developed.
