| molecular cloning and analysis of a novel teratocyte-specific carboxylesterase from the parasitic wasp, dinocampus coccinellae. | teratocytes derived from the embryonic membrane (serosa) of parasitoids are released into the host hemocoel when the parasitoid eggs hatch, where they perform several functions during the post-embryonic stage. a full-length cdna encoding a putative carboxylesterase was isolated from the teratocytes of dinocampus coccinellae and was designated as teratocyte-specific carboxylesterase (tsc). it contained an open reading frame of 2571 bp coding for a protein of 857 amino acids with a calculated mole ... | 2005 | 16102422 |
| response of the ladybird parasitoid dinocampus coccinellae to toxic alkaloids from the seven-spot ladybird, coccinella septempunctata. | electrophysiological and behavioral responses of the ladybird parasitoid dinocampus coccinellae to volatiles from the seven-spot ladybird, coccinella septempunctata, were investigated to identify semiochemicals involved in host location. coupled gas chromatography-electroantennography (gc-eag) with d. coccinellae located a small peak of prominent activity in an extract of volatiles from adult c. septempunctata. the active compound was identified by coupled gc-mass spectrometry and by comparison ... | 2001 | 11382065 |
| the cost of a bodyguard. | host manipulation by parasites not only captures the imagination but has important epidemiological implications. the conventional view is that parasites face a trade-off between the benefits of host manipulation and their costs to fitness-related traits, such as longevity and fecundity. however, this trade-off hypothesis remains to be tested. dinocampus coccinellae is a common parasitic wasp of the spotted lady beetle coleomegilla maculata. females deposit a single egg in the haemocoel of the ho ... | 2011 | 21697162 |
