Myzus 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 (...
متن کاملCage and field assessments of Beauveria bassiana-based Mycoinsecticides for Myzus persicae Sulzer (Hemiptera: Aphididae) control in cabbage.
The efficiency of formulated Beauveria bassiana-based mycoinsecticides to control Myzus persicae (Sulzer) in cabbage was assessed under field conditions. Aqueous conidial suspensions (0.01% Tween 80 + 0.01% v/v Agral) of three fungal isolates were sprayed twice at different dates, each with 2.0 x 10(9) viable conidia per potted plant using screened cages. The number of nymphs and adults of M. p...
متن کاملMicrosatellite isolation, linkage group identification and determination of recombination frequency in the peach-potato aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae).
Fifteen polymorphic microsatellite markers were used to establish linkage groups and relative rates of recombination in male and female Myzus persicae (Sulzer) (Hemiptera: Aphididae) (peach-potato aphid). We cloned nine markers from M. persicae and for these we report primer sequences and levels of allelic diversity and heterozygosity in four Australian M. persicae populations. Of the remaining...
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 کاملRelationship between amount of esterase and gene copy number in insecticide-resistant Myzus persicae (Sulzer).
Overproduction of the insecticide-degrading esterases, E4 and FE4, in peach-potato aphids, Myzus persicae (Sulzer), depends on both gene amplification and transcriptional control, the latter being associated with changes in DNA methylation. The structure and function of the aphid esterase genes have been studied but the determination of their copy number has proved difficult, a common problem w...
