Bioassay studies on the reaction of (Diptera: Culicidae) on different attractants.

BACKGROUND

The studies on mosquito attractants had been develop intensively in the recent years. However, the study on fruit peel extract as mosquito attractant was scarce, even though various fruits had demonstrated the ability to attract different types of mosquito species.

OBJECTIVE

This study aims to determine the potential of (papaya) and (pineapple) peel extracts to attract and .

METHODS

The mosquitoes response to the fruit peel extracts were conducted in the no-choice and choice assay using modified olfactometer. The Preference Index (PI) in each assay was calculated and arcsine transformed before conducting independent -test to determine the significant different between the mean arcsine transformed PI and the tested hypothesis mean PI.

RESULT

No choice assay indicate both species have significant attraction to the papaya and pineapple peel extracts ( < 0.05). In choice assay, is revealed to equally attracted to the papaya and pineapple peel extracts ( > 0.05) while is significantly attracted to the papaya peel extract ( < 0.05).

CONCLUSION

The study had identified that both fruit peel extracts able to attract mosquitoes with is equally attracted to papaya and pineapple peel extracts while is more attracted to the papaya peel extract than the pineapple peel extract.
