Could different environmental conditions select for different flight characteristics in sexual and asexual parasitoid Venturia canescens?

Automictic parthenogenesis in the parasitoid Venturia canescens (Hymenoptera: Ichneumonidae) revisited.

Both arrhenotokous and thelytokous reproduction are known to occur in the parasitoid wasp Venturia canescens. The cytological mechanism of thelytoky was previously reported to involve the formation of a restitution metaphase after the reduction division, but the exact nature of the subsequent divisions, whether reductional or equational, remained unclear. We reinvestigated the cytological mecha...

Adaptations to different habitats in sexual and asexual populations of parasitoid wasps: a meta-analysis

BACKGROUND Coexistence of sexual and asexual populations remains a key question in evolutionary ecology. We address the question how an asexual and a sexual form of the parasitoid Venturia canescens can coexist in southern Europe. We test the hypothesis that both forms are adapted to different habitats within their area of distribution. Sexuals inhabit natural environments that are highly unpre...

biology of venturia canescens, a larval parasitoid of carob moth, ectomyelois ceratoniae under laboratory conditions

the carob moth, ectomyelois ceratoniae zeller (lep.: pyralidae) is the most important pest of pomegranate orchards in iran. this current research was carried out to study the biology of venturia canescens gravenhorst (hym.: ichneumonidae) as one of its larval parasitoids. laboratory studies were conducted on the immature developmental time, adult longevity, functional response, parasite progeny...
