中文摘要: |
苹果蠹蛾Cydia pomonella Linne是为害苹果Malus pumilaMill、梨Pyrus spp.、桃Amygdalus persica L.等仁果类和核果类果树的重要蛀果害虫之一。为明确寄主颜色在苹果蠹蛾产卵中的作用,本文研究了不同颜色对苹果蠹蛾雌成虫产卵选择性的影响。试验采用彩色硫酸纸模拟寄主颜色,以白色为参比色,室内在不同基质颜色条件下连续饲养苹果蠹蛾成虫,测定其产卵量和计算产卵选择率。结果显示,苹果蠧蛾羽化后第2天开始产卵,基质颜色对苹果蠹蛾雌成虫产卵选择率和产卵量有显著地影响,在粉红色上的产卵选择率和产卵量显著高于其它颜色,分别为38.24%和35.0粒,草莓红(6.17%,5.1粒)和橙黄色(8.18%,3.5粒)则表现一定的趋避作用。基质颜色对不同日龄苹果蠹蛾雌成虫产卵选择性亦有显著影响,7日龄显著偏嗜浅绿色(68.31%),其它日龄明显偏嗜粉红色,且在粉红色上日产卵量均高于其它颜色。本研究结果表明寄主颜色在苹果蠹蛾产卵选择中具有重要作用,偏好在粉红色上产卵。 |

The codling moth, Cydia pomonella Linne, is one of the key fruit-boring pests that damage Malus pumila Mill., Pyrus spp. and Amygdalus persica L. and other fruits. In order to determine the role of host color in attracting the oviposition of C. pomonella, the present study examined the effects of various colors on the oviposition preference. Colored tracing paper was used to represent different host colors, with white as the reference color C. pomonella adults were continuously raised on the substrates in different colors under laboratory conditions, and the oviposition rate and preference were estimated on the tracing paper with different colors. We found that the female started laying eggs two days after the eclosion. Oviposition rate varied with different colors, with significantly higher oviposition rate and a preference on pink (averaged as 35.0 eggs and 38.07%) than that of strawberry red (averaged as 5.1 eggs and 7.56%) and that of orange yellow (averaged as 3.5 eggs and 8.37%). The latter two colors appeared to show a repellent effect on the oviposition. The substrate color also had strong effects on the oviposition preference of female adults in different age. The female adults of 7-day old were observed to prefer the light green (68.31%) substrate, while the females of other ages were more attracted to the pink substrate with much more eggs laid by a single female on pink than on the other colors. Our study clearly demonstrated that the color of the host may play an important role in determining the oviposition choice of C. pomonella, and they prefer to lay eggs on the site in pink. |
