BACKGROUND
Drosophilia suzukii Matsumura is an invasive pest insect that lays its eggs in the fruit of several commercially grown crops. An effective oviposition deterrent could contribute to its management. Repellant odors were evaluated in the laboratory and in the field.
RESULTS
Geosmin and 1-octen-3-ol were found to be aversive to seven-day-old female D. suzukii at concentrations of 10(-1) and 10(-2) in laboratory choice tests. Field experiments found that fewer eggs were observed in fruit on the day of harvest and fewer adult D. suzukii were reared from fruit associated with 1-octen-3-ol odors than control fruit in cultivated red raspberry.
CONCLUSION
Geosmin and 1-octen-3-ol induce aversive behaviors in Drosophila suzukii and are potential oviposition deterrents for its management in fruit crops.
背景
铃木氏果蝇是一种入侵性害虫，会在几种商业种植作物的果实中产卵。一种有效的产卵驱避剂可能有助于对其进行管理。在实验室和田间对驱避气味进行了评估。
结果
在实验室选择试验中，发现土臭素和1-辛烯-3-醇在浓度为10⁻¹和10⁻²时对7日龄的铃木氏果蝇雌虫具有厌恶作用。田间试验发现，在栽培的红树莓中，收获当天果实上观察到的卵较少，与1-辛烯-3-醇气味相关的果实中羽化出的铃木氏果蝇成虫比对照果实少。
结论
土臭素和1-辛烯-3-醇会引发铃木氏果蝇的厌恶行为，是水果作物中用于管理该果蝇的潜在产卵驱避剂。
