Abstract
Abstract
Plant semiochemicals play an important role in the search process and host acceptance by insects. The presence of complex volatiles in plants may be used for the purpose of integrated pest management. The objective of this study was to detect the response of Zeugodacus cucurbitae fruit flies of different ages to the chemical compounds of host plants using methanol as a solvent. The results showed that the olfactometer test on the response of Z. cucurbitae fruit fly attraction to plant bioactive compounds through the Methanol fraction, the fastest and longest response was found in the methanol fraction of leaves and bitter melon fruit 23 minutes 2 seconds and the lowest was in the methanol fraction of cucumber leaves 14 minutes 24 seconds. The attraction response was based on the age of the females of the fruit fly aged 1-2 days, females aged 8-10 days after copulation, and females after egg-laying. The highest response of interest in the olfactometer was found in female fruit flies aged 8-10 days (post-copulation and pre-oviposition) on luffa, bitter guard and cucumber plants.
