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...
متن کاملLife tables of Venturia canescens (Hymenoptera: Ichneumonidae) parasitizing the Mediterranean flour moth (Lepidoptera: Pyralidae).
Effects of temperature, adult feeding, and host instar on life table parameters of Venturia canescens Gravenhorst (Hymenoptera: Ichneumonidae) parasitizing larvae of Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) were studied in the laboratory. Experimental adults lived under various regimes of temperature (15, 20, 25, and 30 degrees C), food supply (with or without access to honey), and h...
متن کاملEvidence for serine protease inhibitor activity in the ovarian calyx fluid of the endoparasitoid Venturia canescens.
Endoparasitic wasps are able to develop inside permissive host insects due to their ability to overcome or evade the host's immune system. In the present study, we provide experimental evidence that ovarian calyx fluid of the ichneumonid endoparasitoid Venturia canescens has the potential to alter host haemocyte spreading and inhibit host haemolymph melanisation due to the presence of a putativ...
متن کاملbiology 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...
متن کاملReproduction and larval rearing of amphibians.
Reproduction technologies for amphibians are increasingly used for the in vitro treatment of ovulation, spermiation, oocytes, eggs, sperm, and larvae. Recent advances in these reproduction technologies have been driven by (1) difficulties with achieving reliable reproduction of threatened species in captive breeding programs, (2) the need for the efficient reproduction of laboratory model speci...
