Physio-Morphic Characters of Different Varieties/Genotypes Against Population Fluctuation of Sucking Pests of Brinjal Solanum melongena (L.)
Abstract:
A field experiment was conducted at Agricultural Research Farm of Banaras Hindu University, Varanasi during 2014-15 and 2015-16 to study different varieties/genotypes of brinjal to find out the role of physio-morphic characters of plant on the population fluctuation of sucking pests. The physio-morphic characters of brinjal plant were correlated with the population of sucking pests. The Moisture percentage, leaf area, hair density and length of hairs of different brinjal varieties/ genotypes influenced the population of sucking pests significantly. The moisture percentage in leaves and leaf area showed non-significant positive relation with the sucking insects like aphids, jassids and whiteflies. The hair density had significant negative correlation with the occurrences of jassids but non-significant negative correlation with the occurrences of aphids and whiteflies. The length of hairs had significant negative impact on jassid infestattion and non-significant negative impact on aphid and whitefly infestation.
