35 SUMMARY AND CONCLUSION The major thrust of this work is to find the repellent effects of Origanum vulgare against the Supella longipalpa at different exposure time. Origanum vulgare plant is one of the richest sources of organic chemicals on earth. Its components are highly volatile components have been found to act as insect deterrents. The repellent effects of different plant extract at different time durations are significantly different. So, an attempt is undertaken to evaluate the efficiency of Origanum vulgare plant extract owing to its insecticidal properties. Even though pesticides can curb many diseases and pest growth; its side effects are also highly noticeable. In this context the relevance of the study becomes essential as the usage of natural plant can eliminate the possibility of using other harmful pesticides or chemicals. A natural material like Origanum vulgare, have the features essential for a safe insecticide, such as proved to be effective against cockroaches, Supella longipalpa. Relatively short lifespan (biodegradable), less toxicity to non-target organisms, easy availability, easily accessible, renewable, and economically cheap and several bioactive varieties are available. So plant can be considered as good alternative to be synthetic and biological method of insect control. The study indicates plant extracts of Origanum vulgare to be useful for this purpose and can be introduced as repellants against various insect pests and can be used in wide application in many industrial and commercial purposes, so future prospect of the study lies in the fact that more plant species should be identified and utilized for such pest repellent activities so that an eco-friendly approach can be followed for sustainable development of the nature and its dependents.

36 Recommendations Based from the finding and conclusions, the following are the recommendations that are essential to the ideas to move the study forward. 1. Future researchers should restrict the external factors that may affect the experiment such as the time of experiment, place of experiment, sizes of cockroach, source of cockroach, and the equal number of male and female cockroach. 2. Future researchers can make other product using oregano. (i.e. sprays, incense, coils, oil, powder, etc.) 3. Future researchers should study the secondary metabolize compound of oregano. 4. To make another research problem for the existing study, future researchers may use other experimental animal or insect that can cause harm or damage in the environment down to the individuals.
