Methyl eugenol, mint lure, BWS, and banana lure did not affect capturing them. In contrast, methyl eugenol had a pronounced effect on females of Zeugodacus tau (50) species of fruitflies while cue lure had zero effect. Other treatments had a less significant effect. Similarly, traps baited with cue lure had a significant effect on Zeugodacus scutellaris sp. (60.67) while others didn’t record any of them. Cue lure also reported more population of male. Zeugodacus cucurbitae sp. (23.33) and ACV attracted 8 fruitflies of cucurbitae sp. No species of cucurbitae were observed in other lures. The less significant population of females of Zeugodacus cucurbitae was observed in either lure or traps (Table 3).

Likewise, females of Zeugodacus tau were reported in Methyl eugenol trap among all in comparison. Figure 1 Population density of male and female Zeugodacus sp. trapped at the study sites
