abstract
Aphis gossypii Glover (Homoptera, Aphididae), Amrasca biguttula biguttula (Ishida) (Hemiptera, Cicadellidae) and Leocinodes orbonalis Guenee (Lepidoptera, Pyralidae) are serious pests of S. melongena in Pakistan. Using host plant resistance can be safe and cheap alternative to insecticidal control of insect pests of S. melongena. The present study was conducted at the New Developmental Farm (NDF) of The University of Agriculture, Peshawar (UAP) in 2014. Three Brinjal genotypes Shamli, pearl long and black beauty were used in the study. Pest infestation started in the first week of May. Overall mean density of A. gossypii was non-significantly higher (0.71 individuals leaf-1) on Black Beauty and lower (0.66 A. gossypii leaf-1) on Pearl Long. Overall mean density of A. biguttula biguttula was non-significantly higher (each 0.47 individuals leaf-1) on Shamli and Black Beauty and lower (0.44 individuals leaf-1) on Pearl Long. Fruit infestation by L. orbonalis was significantly lower (35 infested fruits/100) for Shamli and higher (53 infested fruits/100 fruits) for Black Beauty. L. orbonalis produced significantly higher number of holes (7.7 holes/fruit/week) on Black Beauty and lower number (2.6 holes/fruit/week) on Shamli. Overall mean yield of the brinjal genotypes was significantly higher for Shamli with 4923.1 kg/ha and lower for Pearl Long with 1230.8 kg/ac. Density of the three pests was comparatively lower on Shamli and its yield was significantly higher than the other two genotypes. Based on the above mentioned results Shamli brinjal genotype is recommended to the growers in Peshawar.
