Herlihy et al.: Distribution of Cotesia rubecula and Displacement of C. glomerata 461 DISTRIBUTION OF COTESIA RUBECULA (HYMENOPTERA: BRACONIDAE) AND ITS DISPLACEMENT OF COTESIA GLOMERATA IN EASTERN NORTH AMERICA
A survey was conducted from May to Oct of 2011 of the parasitoid community of the imported cabbageworm, Pieris rapae (Lepidoptera: Pieridae), in cole crops in part of the eastern United States and southeastern Canada. The findings of our survey indicate that Cotesia rubecula (Hymenoptera: Braconidae) now occurs as far west as North Dakota and has become the dominant parasitoid of P. rapae in th...
متن کاملIntroduction and evaluation of Cotesia rubecula, a parasitoid of Pieris rapae in New Zealand
The host specificity of Cotesia rubecula (Marshall) was examined through literature searches, behavioural and ecological observations, and host specificity tests of a South Australian population. The results led to the importation and testing of C. rubecula in quarantine in New Zealand where its specificity to the genus Pieris was confirmed. Introduction of the parasitoid was approved and the s...
متن کاملIsolation and characterization of a Cotesia rubecula bracovirus gene expressed in the lepidopteran Pieris rapae.
Polydnaviruses are endogenous particles that are crucial for the survival of endoparasitoid wasps, providing active suppression of the immune function of the lepidopteran host in which wasp larvae develop. The Cotesia rubecula bracovirus (CrBV) is unique in that only four gene products are detected in larval host (Pieris rapae) tissues and expression of CrBV genes is transient, occurring betwee...
متن کاملThe mechanism of the emergence of Cotesia kariyai (Hymenoptera: Braconidae) larvae from the host
At maturity, the endoparasitoid larvae of several subfamilies of the Braconidae have to emerge from inside of the host to pupate. Although the hosts hormonal milieu and the timing of larval parasitoid emergence have been studied, no report has yet focused on the physiological state of the host in connection with the emergence behavior of endoparasitoids. We investigated the mechanism of larval ...

به‌منظور شناسایی پارازیتوییدهای سفیده‌ی کوچک کلم، Pieris rapae (Linnaeus, 1758) (Lepidoptera: Pieridae) از مزارع کلم‌گل در جنوب تهران، در سال 1390 نمونه‌برداری صورت گرفت. در بین نمونه‌ها گونه‌ی Hyposoter clausus (Brischke, 1880)(Hymenoptera: Ichneumonidae) برای اولین‌بار از از روی سفیده‌ی کوچک کلم و منطقه‌ی تهران گزارش می‌شود. گونه‌ی دیگر به‌نام Cotesia glomerata L. (Hymenoptera: Braconidae) نی...
