Pheromone baited biopesticide for control of Leucinodes orbonalis Guenee in brinjal plant

Abstract

Leucinodes orbonalis Guenee, Brinjal fruit and shoot borer (BFSB), is the major pest on brinjal world wide. Larvae of this pest cause the damage; which at initial stages adversely affect the shoot growth, and in later stages diminish fruit quality. Spraying of insecticides is the main pest control method. This has been absolutely ineffective due to concealed habit of the larvae. Such a phenomenon apprehends to the development of insecticides resistance which demands continuously increasing doses. Manipulating the insect behavior using semiochemicals could be an opportunity for better management of insect pest. Application of BFSB sex pheromone components (E)-11-hexadecenyl acetate (E11-16: Ac) alone or in combination with (E)-11-hexadecen-1-ol (E11-16: OH) in traps can be used to suppress the populating growth. Goal-oriented interdisciplinary research on semiochemicals for sound administration of BFSB will depend on a better understanding of the key chemical ecology stimuli of relevance to the pest.
