ABSTRACT

Wheat (Triticum aestivum L.) is a major crop with one of the largest area under cultivation playing a significant role in economic stability of Pakistan. Among other pests aphid is a major one which contributes towards low yield on wheat farms. Different wheat developmental periods, i.e., seedling (SS), tillering (TS), stem elongation (SES), heading (HS), dough (DS) and ripening (RS) were studied. Through evaluating, seven varieties i.e. Sahar-2006, Faisalabad-2008, Punjab-2011, Galaxi-2013, Gold-2016, Fakhr-e-Bhakkar-2017 and Bhakkar Star-2018 the most susceptible wheat stage against the infestation of aphid was investigated. Exploring most susceptible wheat stage was conducted through most common aphid species, i.e., Rhopalosiphum padi, Schizaphis graminum, Sitobion avenae on different varieties. Results indicated that heading and dough stages (Standard Weeks 10 and 11) were most susceptible developmental periods with average 10.56 and 8.36, 21.98 and 18.65 aphids per tiller during 2018 and 2019, respectively. R. padi was most dominant from mid-January to mid-April with maximum population of 100, 84.33, 44.31 and 1.64 % in 2018 as well as 100, 89.78, 22.08, and 0.29 % in 2019. S. graminum 12.97, 46.93, 64.74% in 2018 as well as 4.53, 42.00, 49.50 % in 2019. It was most dominant from 1st week of February to1st week of April. S. avenae population was 2.70, 8.75, 33.62 % in 2018 as well as 00.00, 15.13, 56.56 % during months of February, March and April, respectively. S. avenae was most dominant from 4th week of March to 2nd week of April during both years. Faisalabad-2008 and Sahar-2006 were most prone to aphid attach having maximum aphid populations during 2017-19. Fakhr-e-Bhakkar-2017 depicted minimum average aphid susceptibility having population of 2.94, 2.58 and 3.08 per tiller during years 2017, 2018 and 2019, respectively.
