The green bug (Schizaphis graminum) (Homoptera: Aphididae) is a big aphid species ambushing wheat crop in Pakistan, and is also stated as a major grain pest across the world. Host plant fighting is an integral part of Integrated Pest Management (IPM). Several green bug opposing genes have been identified and imported in commercial high flexible cultivars of wheat to survive green bug. There are three known insect fighting categories, including antixenosis, antibiosis and fortitude. Furthermore, using direct current electrical seepage graphs (DC-EPG) indicated that Parameters related to strainer element stages the aphid reached fast on susceptible cultivar compared to ‘opposing’ plants. The percentage of time abandoned available after first strainer element time, Schizaphis graminum stayed for a significant more protracted period on susceptible cultivar distinguished to the resistant cultivars. The aphid pierced sieve elements development and phloem ingestion attitude was initiated with different success on resistant and exposed genotypes. EPG indicates that phloem ingestion action is significantly reduced on opposing wheat lines distinguished to the susceptible cultivar. The duration of acute the pathway phase by S. graminum, was considerably different between control plants and the proven genotypes. Similar response was observed all the while the last parameter ‘mean fraction time’ where the bug has spent significantly more interminable time on susceptible cultivar distinguished to the resistant genotypes.
