| 中文摘要: |
| 瓜实蝇Zeugodacus cucurbitae Coquillett是一种危害多种瓜果蔬菜的重要农业害虫，因其产卵隐蔽、幼虫蛀果为害，导致防治工作极其困难。为筛选出对瓜实蝇成虫具有驱避及毒杀活性的植物精油，本研究测定了11种芳香植物精油对瓜实蝇成虫的驱避活性和毒杀活性，旨在为绿色高效防控瓜实蝇奠定理论基础。首先采用Y型嗅觉仪行为选择法，研究了不同植物精油对瓜实蝇的行为驱避活性；然后采用果实喷雾法方法，研究了不同植物精油对瓜实蝇产卵驱避活性；最后通过药膜触杀法和胃毒法，研究了驱避活性最高的植物精油对瓜实蝇的毒杀活性。结果表明，在供试的11种精油中，栀子花Gardenia jasminoides Ellis精油对瓜实蝇行为选择和产卵驱避活性最强，在200 μL/mL时产卵驱避率高达94.69% ± 2.36%；栀子花精油在35 mg/mL时对瓜实蝇成虫的触杀死亡率为92.00% ± 4.36%，雌、雄成虫LC50值分别为15.289 mg/mL、10.705 mg/mL；胃毒死亡率为94.00% ± 2.46%，雌、雄成虫LC50值分别为16.169 mg/mL、6.901 mg/mL。本研究发现栀子花精油对瓜实蝇成虫有显著的驱避和毒杀活性，为开发瓜实蝇绿色高效行为调控剂及毒杀剂提供理论依据。 |
| 英文摘要: |
| The melon fly, Zeugodacus cucurbitae Coquillett, is a significant agricultural pest that endangers a variety of fruits and vegetables. Because of its hidden oviposition and larval fruit damage, it is extremely difficult to control. To screen plant essential oils (EOs) with repellent and insecticidal activity against adult Z. cucurbitae, this study evaluated the behavioral repellency and toxicity of 11 aromatic plant EOs, aiming to establish a theoretical foundation for eco-friendly and efficient management of this pest. First, the behavioral repellency of different EOs against Z. cucurbitae was assessed using a Y-tube olfactometer choice assay. Subsequently, the oviposition deterrent activity was tested by fruit spray method. Finally, contact and oral toxicity of the highest repellent activity EO were determined through the drug film contact method and stomach poison method, respectively. The results showed that among the 11 tested EOs, Gardenia jasminoides Ellis EO exhibited the strongest behavioral and oviposition deterrent effects, achieving an oviposition repellency rate of 94.69% ± 2.36% at 200 μL/mL. At 35 mg/mL, G. jasminoides EO caused 92.00% ± 4.36% contact mortality in adults, with LC50 values of 15.289 mg/mL (females) and 10.705 mg/mL (males). Additionally, the oral toxicity mortality rate was 94.00% ± 2.46%, with LC50 values of 16.169 mg/mL (females) and 6.901 mg/mL (males). This study reveals that G. jasminoides Ellis EO possesses significant repellent and insecticidal activity against adult Z. cucurbitae, providing a theoretical basis developing eco-friendly behavioral regulators and toxic agents for Z.cucurbitae. |
