【摘要】 先提供气味刺激,再提供含不同寄主植物叶片提取物的蜜糖刺激,采用Y型嗅觉仪测定了3种寄主植物(丝瓜、番茄和菜豆)叶片表面非挥发性次生化合物刺激对美洲斑潜蝇Liriomyza sativae雌成虫嗅觉记忆的影响。结果表明:菜豆叶片沸水提取物能促进雌成虫对芳樟醇的嗅觉记忆,而丝瓜和番茄叶片沸水提取物则能提高雌成虫对正己烷的记忆能力。因此,不同寄主植物叶片提取物影响了美洲斑潜蝇雌成虫对不同气味的嗅觉记忆。更多还原

【Abstract】 Effects of the boiling water extractions of leaves from three host plants (tower gourd, tomato and kidney bean) on the olfactory memory of female adults of the vegetable leafminer, Liriomyza sativae were investigated with Y-type olfactometer by firstly exposing females to linalool diluted with hexane (1∶104, v/v) for 1 h and then to 10% honey water mixed with boiling water extractions of leaves from host plants for 24 h. The results indicated that the extraction of kidney bean leaves promoted the olfactory memory of females to linalool, while the extraction of towel gourd or tomato leaves improved the olfactory memory to hexane. It was so inferred that the extractions of leaves from different host plants might have different influences on the olfactory memory of L. sativae females.更多还原
