Functional response and mutual interference of Diaeretiella rapae (Hymenoptera: Aphidiidae) on Brevicoryne brassicae (Homoptera: Aphididae)
Functional response and mutual interference are the most important behavioural characteristics that reveal different aspects of host–parasitoid interactions. In this study, functional response and mutual interference of the parasitoid wasp, Diaeretiella rapae (M’Intosh) attacking the cabbage aphid, Brevicoryne brassicae (Linnaeus) were investigated. Logistic regression was used to distinguish t...
متن کاملRepellency and toxicity of three Impatiens species (Balsaminaceae) extracts on Myzus persicae Sulzer (Homoptera: Aphididae)
The extracts of Impatiens noli-tangere, I. parviflora and I. glandulifera (Balsaminaceae) were evaluated for their effect on green peach aphid (Myzus perssicae), an important insect pest of many plants. All the extracts showed insecticidal and repellent activity. After 54 h of exposure, the most active extract was Impatiens parviflora with 99.7 and 90.0 % mortality at 0.5 and 0.1 % concentratio...
متن کاملDiaeretiella rapae limits Myzus persicae populations after applications of deltamethrin in oilseed rape.
In fall, Myzus persicae (Sulzer) (Homoptera: Aphididae) may exhibit population resurgence in winter oilseed rape in France. This resurgence may arise from pyrethroid treatments against Coleoptera (Psylliodes chrysocephala L.) that either kill parasitoids present during treatment or prevent recolonization by off-crop parasitoids. We studied the impact of Diaeretiella rapae (M'Intosh) (Hymenopter...
متن کاملIdentification and validation of reference genes for gene expression analysis in Aphidius gifuensis (Hymenoptera: Aphidiidae)
Reference genes have been utilized in estimating gene expression levels using quantitative reverse transcriptase-quantitative polymerase chain reaction (qRT-PCR) analysis. Aphidius gifuensis Ashmaed is one of the most widely used biological control agents for aphids. The biological properties of this species have been studied in detail, and current investigations are focused on elucidating the ...
متن کاملMyzus persicae Sulzer aphid contains oxylipins that
Oxylipins are oxygenated fatty acids and their derivatives that play key roles in response to stress. They are widespread in many organisms including mammals or plants but are unknown in arthropods. In this study, we identified oxylipins in Myzys persicae Sulzer aphids reared on Vicia faba L. plants. Further experiments based on: (i) Radiolabelled substrate incubation with aphid extracts, and (...
