瓜实蝇对不同果香香精的趋向行为研究

Taxis Responses of Zeugodacus cucurbitae (Coquillett) to Different Fruit Flavors

本研究选取与瓜实蝇偏好寄主植物果实以及对其具有强引诱作用的非寄主果实相关的果香香精8种,研究了瓜实蝇对这些香精的趋向行为。结果表明,瓜实蝇对不同果香香精表现出不同的趋向行为。室内室外的初筛结果均表明瓜实蝇偏好榴莲香精和南瓜香精,且两种香精诱集的瓜实蝇雌雄虫数量并无显著差异。通过Y型嗅觉仪行为测定发现瓜实蝇最偏嗜10%(w/V)的榴莲香精和南瓜香精。基于本研究的结果,建议选择10%的榴莲香精和南瓜香精溶液用于瓜实蝇的监测和诱杀防治。

In this study,we selected eight kinds of fruit flavors relating to Zeugodacus cucurbitae hobby hosts and non-host fruits(but they have strong attraction effect on Z.cucurbitae),and examined the taxis responses of Z.cucurbitae to these flavors.The results showed that Z.cucurbitae had different responses to the eight different flavors.The indoor and outdoor experiments indicated that Z.cucurbitae preferred selecting the durian flavor and pumpkin flavor.The number of male and female Z.cucurbitae trapped by the two flavors were not significantly different.According to the test of Y-tube olfactometer,Z.cucurbitae preferred 10%(w/V)of durian and pumpkin flavors.Based on the results,10%(w/V)of durian and pumpkin flavors could be used to monitor and trap Z.cucurbitae.
