In Arabidopsis thaliana, PHYTOALEXIN DEFICIENT 4 (PAD4) functions as a key player in modulating defence against the phloem sap-feeding aphid Myzus persicae (Sülzer), more commonly known as the green peach aphid (GPA), an important pest of a wide variety of plants. PAD4 controls antibiosis and antixenosis against the GPA. In addition, PAD4 deters aphid feeding from sieve elements on Arabidopsis....

Pear psylla (Cacopsylla pyricola Foërster) is the most serious pest of the European pear (Pyrus communis L.) in the production regions of Europe and North America. Nine plant germplasm introductions of pear from Central Europe recently released from plant quarantine were evaluated for nymphal feeding antixenosis, a primary mode of resistance known to be correlated with ovipositional antixenosis...

Due to the detrimental side-effects of synthetic pesticides, use nonchemical strategies in management insect pests is necessary. In present study, susceptibility fourteen eggplant cultivars green peach aphid (M. persicae) were investigated. According preliminary screening tests, ‘Long-Green’, ‘Ravaya’ and ‘Red-Round’ as relatively resistant, ‘White-Casper’ ‘Pearl-Round’ susceptible recognized. ...

White-backed planthopper, Sogatella furcifera Horváth (Hemiptera: Delphacidae) is a migratory and serious pest of rice crop worldwide including Pakistan. The current experiment was carried out to assess the antixenosis antibiosis level fifteen genotypes against S. under greenhouse conditions. In studies, proportion nymphs adults settled recorded in relation control. Less preferred varieties by ...
