ABSTRACT
The efficacy of Voliam flexi (thiamethoxam 17.6% + chlorantraniliprole 8.80%), Neem oil (5%), Trichogramma chilonis Ishii (Hymenoptera:Trichogrammatidae) was evaluated against brinjal fruit and shoot borer (Leucinodes orbonalisGuenee) (Lepidoptera, Crambidae) in brinjal (Solanummelongena) experimental field at the Agriculture Research Institute Tarnab, Peshawar, Khyber Pakhtunkhwa-Pakistan during 2016.The treatments were arranged in RCBD with three replications and the chemical and botanical insecticides were used with ten days interval while theT. Chilonis (500 eggs/cards) were released with thirty days intervals. A single variety of brinjal (Neelam) was used in the experiment. Significantly low infestation of shoots (8.19%) and fruits (6.23%) were recorded in the plots treated with Voliam flexi followed by Neem oil and T. Chilonis with 12.77 and 12.73%, and 14.01 and 16.37% shoots and fruit infestation, respectively. Significantly high infestation of shoots 20.35 and 25.78% fruits was recorded in control plot. The yield data showed that significantly maximum yield was recorded in Voliam flexi and Neem oil treated plots. It was concluded from the experiment that Voliam flexi is the best control measure against brinjal fruit and shoot borer, L. orbonalis. The effective treatment which resulted high marketable yield after synthetic insecticide was Neem Oil. Herefore, by sacrificing some yield of brinjal the Neem oil is recommended as an environment friendly management technique for brinjal shoot and borer.
