Research Description A deeper understanding of the chemically-mediated behavior of insects leads to the development of an IPM component in crop production. Repellents emitted by plants in the ecosystem can be utilized to reduce insect pest populations. In as much as there is farmer knowledge on the usefulness of tagbak and kakawate for pest management, these are guides for chemical ecology studies to provide the basic information on the repellent volatile chemicals. The volatile organic chemicals which can affect behavior of insect pests, eggplant fruit and shoot borer in particular, has been identified as a research gap as the volatile chemicals of intact eggplant has not been analyzed and needs to be further studied. The identification of the chemical oviposition stimulants can be utilized in breeding efforts for eggplant where the gene responsible for the expression of stimulant or repellent chemical can be suppressed or enhanced, to increase of eggplant against eggplant fruit and shoot borer. Studies should be undertaken to identify the chemical responsible for the ovipositional non-preference and the controlling gene. Incorporation of the gene in eggplant varieties with antibiotic effects being developed would result in more durable resistance to EFSB.
Research Objectives This study aims to investigate the volatile organic chemical profile of various eggplant varieties with varying susceptibilities to eggplant fruit shoot borer and relate the presence of these chemicals to oviposition preference of this major insect pest. It will also determine the volatile organic chemical profile of tagbak and kakawate to validate farmer knowledge on the usefulness of these plants in insect pest management in rice and tomato production.
