为明确环境颜色与梨小食心虫Grapholita molesta Busck成虫产卵生物学的关系,在室内条件下,以红、橙、黄、绿、蓝和紫色6种颜色卡纸模拟环境颜色,分别测定了其对梨小食心虫成虫产卵生物学参数的影响。结果显示:产卵前期以紫色背景下最长,为7.32 d,黄色背景下最短,为4.94 d;产卵期以绿色背景下最长,为13.53 d,紫色背景下最短,为8.57 d;单雌产卵量以黄色背景下最多,为90.18粒,绿色背景次之,为88.29粒;绿色和蓝色背景下交配率最高,为96.08%,紫色背景下最低,为62.22%;雌成虫寿命蓝色背景下最长,为22.26 d,绿色背景次之,为22.19 d;紫色背景下卵发育历期最长且孵化率最低。表明环境颜色可以影响梨小食心虫成虫的产卵生物学。
In order to clarify the relationship between environmental color and ovipositional biology of Grapholita molesta Busck adults, the color of the environment was simulated under 6 color cardboards of red, orange, yellow, green, blue and purple under indoor conditions. Influence of the parameters of oviposition biology on adult. The results showed that the longest pre-oviposition period was 7.32 days in purple background and 4.94 days in yellow background, the longest was 13.53 days in green background and the shortest was 8.57 days in purple background. Single Female fecundity was the highest in yellow background, 90.18 grains, followed by green background, 88.29 grains; the highest mating rate was 96.08% under green and blue background, the lowest was 62.22% under purple background; The longest in the color background was 22.26 days, followed by the green background was 22.19 days, and the longest in the purple background and the lowest in the hatching rate. It shows that the color of the environment can affect the oviposition biology of adult pest moth.
