| aphid parasitoid complex in potato in the context of ipm in belgium. | parasitic hymenoptera of potato aphids were collected and identified in 2000 and 2001 in 11 potato fields in belgium. nine aphidiidae species, parasiting seven aphid species, were found: aphidius ervi, aphidius matricariae, aphidius picipes, binodoxys angelicae, diaeretiella rapae, praon abjectum, praon gallicium, praon volucre and toxares deltiger. a. ervi and a. picipes were the dominant and sub-dominant species, with 54% and 28% of the primary parasite collected, respectively. both species an ... | 2005 | 16628888 |
| effect of temperature on life history of aphidius colemani and aphidius matricariae (hymenoptera: braconidae), two parasitoids of aphis gossypii and myzus persicae (homoptera: aphididae). | the performance of two aphid parasitoids, aphidius colemani viereck and aphidius matricariae (haliday), against aphis gossypii glover on greenhouse cucumber (cucumis sativus l.) and myzus persicae (sulzer) on sweet pepper (capsicum annuum l.) were evaluated at various constant temperatures. biological parameters of both parasitoids including developmental time, pupal survivorship, percentage of parasitism, and sex ratio of the progeny were studied at 5, 10, 15, 20, 25, 30, and 35 degrees c. at 2 ... | 2007 | 17445360 |
| lack of behavioural evidence for kin avoidance in mate choice in a hymenopteran parasitoid (hymenoptera: braconidae). | mechanisms for inbreeding avoidance should be prevalent in insects that reproduce by arrhenotokous haplodiploidy because of the higher potential production of unviable diploid males in inbred matings. few studies have focused on mating strategies in insect parasitoids and even less on kinship relationships during mate choice. in this study we tested avoidance of kin as mate in the parasitic wasp aphidius matricariae (hymenoptera: braconidae) using an ethological approach. key mating parameters, ... | 2009 | 19429202 |
