中文摘要:
橘小实蝇Bactrocera dorsalis (Hendel) 是近几年入侵江苏南部地区,严重危害当地水果、蔬菜的重要害虫。为深入了解其在该地区果树、蔬菜上的产卵特性,进行植物果实、颜色和形状对其产卵选择影响的研究。实验室中“纸杯法”的产卵选择试验结果表明,橘小实蝇对不同水果的产卵偏好性由高到低依次为:柑橘、香蕉、芒果、枣、石榴、苹果、桃子、梨、李、葡萄、柿;对不同蔬菜的产卵偏好性由高到低依次为:丝瓜、豇豆、苦瓜、黄瓜、茄子、南瓜、青椒、番茄。对不同寄主颜色和形状的产卵选择特点为,雌虫常选择桔黄色、绿色,以及圆球形的寄主产卵, 而较少选择黑色、方形的寄主产卵。从试验结果可以看出,寄主果实散发出的气味,及其颜色和形状对橘小实蝇的产卵选择有影响。
英文摘要:The oriental fruit fly Bactrocera dorsalis (Hendel), a polyphagous pest invaded South Jiangsu Province in recent years, and seriously destroyed different species of fruits and vegetables. The experiment by using per-cup was set to determine the effects of hosts and fruit color and shape on the oviposition preference of oriental fruit fly in the laboratory. The result showed that the oviposition preference of B. dorsalis to different fruit hosts from high to low was orange, banana, mango, jujube, pomegranate, apple, peach, plum, grape and persimmon, and the preference to vegetables hosts from high to low was: towel gourd, cowpea, balsam pear, cucumber, brinjaul, pumpkin, green pepper and tomato. Female adults preferred the orange and green colors and rounded fruits to black and quadrate ones. It indicated that the odor, color and shape of host fruits significantly affected B. dorsalis oviposition preference.
