Repellency 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 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 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 (...
متن کاملResponse of Myzus Persicae (sulzer) to Imidacloprid and Thiamethoxam on Susceptible and Resistant Potato Varieties
Among insect pests the Green peach aphid Myzus persicae (Sulzer) is one of the most damaging virulent insect to potato crop. Research experiment was conducted at Research Farm of Khyber Pakhtunkhwa Agricultural University Peshawar, Pakistan during spring 2008 to test two insecticides against Myzus persicae on two potato varieties viz Kuroda and Desiree. The results revealed that both the insect...
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...
