Age and diet influence the composition of venom from the endoparasitic wasp Pimpla turionellae L. (Hymenoptera : Ichneumonidae)
Uçkan, Fevzi; Ergin, Ekrem; Rivers, David B.; Gençer, Nahit (Wiley-Liss, 2006)Venom from the endoparositic wasp Pimpla turionellae L. (Hymenoptera: Ichneumonidae) was found to contain a complex mixture of biogenic amines, noradrenalin, phospholipase 13, and several proteins and peptides. The amount ... -
Changes in the hemolymph total protein of Galleria mellonella (Lepidoptera: Pyralidae) after parasitism and envenomation by Pimpla turionellae (Hymenoptera: Ichneumonidae)
Sak, Olga; Ergin, Ekrem; Uçkan, Fevzi; Rivers, David B.; Er, Aylin (Tubitak Scientific & Technical Research Council Turkey,, 2011)Venom from the endoparasitoid Pimpla turionellae L. (Hymenoptera: Ichneumonidae) contains a mixture of biologically active components, which display potent paralytic, cytotoxic, and cytolytic effects towards hosts. Here, ... -
Characterization and biochemical analyses of venom from the ectoparasitic wasp Nasonia vitripennis (Walker) (Hymenoptera : Pteromalidae)
Rivers, David B.; Uçkan, Fevzi; Ergin, Ekrem (Wiley,, 2006)During parasitism, the ectoparasitic wasp Nasonia vitripennis (Walker) (Hymenoptera: Pteromalidae) induces a developmental arrest in host pupae that is sustained until the fly is either consumed by developing larvae or the ... -
Cytotoxic effects of parasitism and application of venom from the endoparasitoid Pimpla turionellae on hemocytes of the host Galleria mellonella
Er, Aylin; Uçkan, Fevzi; Rivers, David B.; Sak, Olga (Wiley, 2011)In parasitoid species devoid of polydnaviruses and virus-like particles, venom appears to play a major role in suppression of host immunity. Venom from the pupal endoparasitoid Pimpla turionellae L. (Hymenoptera: Ichneumonidae) ... -
Effect of cypermethrin exposed hosts on egg-adult development time, number of offspring, sex ratio, longevity, and size of Apanteles galleriae Wilkinson (Hymenoptera : Braconidae)
Ergin, Ekrem; Er, Aylin; Uçkan, Fevzi; Rivers, David B. (Soc Royale Zoologique Belgique, 2007)The effects of sub-lethal doses of cypermethrin onto the larval host Achoria grisella Fabr. (Lepidoptera : Pyralidae) were evaluated on egg-adult development time, number of offspring produced, sex ratio, longevity, and ... -
Effects of parasitization and envenomation by the endoparasitic wasp Pimpla turionellae (Hymenoptera: Ichneumonidae) on hemocyte numbers, morphology, and viability of its host Galleria mellonella lepidoptera: Pyralidae)
Er, Aylin; Uçkan, Fevzi; Rivers, David B.; Ergin, Ekrem; Sak, Olga (Oxford Univ Press Inc, 2010)Venom from the pupal endoparasitoid Pimpla turionellae L. (Hymenoptera: Ichneumonidae) contains a mixture of biologically active components, which display potent paralytic, cytotoxic, and cytolytic effects toward hosts. ... -
In vivo and in vitro activity of venom from the endoparasitic wasp Pimpla turionellae (L.) (Hymenoptera : Ichneumonidae)
Ergin, Ekrem; Uçkan, Fevzi; Rivers, David B.; Sak, Olga (Wiley, 2006)The biological activity of venom from Pimpla turionellae L. (Hymenoptera: Ichneumonidae) was examined in vivo toward larvae and pupae of Galleride mellonella L. (Lepidoptera: Pyralidae), and in vitro toward bacterial and ...
