Abstract

Based on previous field screening data 15 genotypes were selected (based on the number of insect pests population/plant) to study the role of morphological parameters of sesame. Trichome density, length and width were estimated under microscope with the help of software. The 15 selected genotypes of sesame were studied for finding trichome’s role in host plant resistance against major sucking pests; whitefly Bemisia tabacι), leafhopper (Orocius albicinctus) and mirid bug (Nesidiocoris tenuis) of sesame and the correlation studies revealed that the density of non-glandular trichome showed significant positive correlation with the population of Orocius albicinctus (r= 0.868), Nesidiocoris tenuis (r=0.549) and Bemisia tabaci (r= 0.824) while length and width of non-glandular trichomes and density of glandular trichomes showed non-significant (±) impact on the incidence of tested sucking insect pests.
