摘要: 环境颜色作为一种物理信号会影响昆虫的繁殖行为,进而影响其种群结构和动态。本试验在室内条件下研究了重要捕食性天敌七星瓢虫在不同颜色环境条件下的产卵习性和生殖力。结果表明,与对照组(无颜色)(453.30粒)相比七星瓢虫在红色(620.67粒)环境中产卵量显著提高。七星瓢虫在不同颜色环境中卵的孵化率均在80%左右,且与对照组无显著性差异。此外,七星瓢虫可以在纸质的产卵载体(圆锥形纸筒)中产卵。在红、蓝、黄和绿色的产卵载体中产卵量分别为223.67、269.33、199.00和137.67粒,均显著高于对照组(66.33粒)。本研究结果对利用特殊环境条件提高七星瓢虫大规模饲养效率以及卵的收集效率提供一定的理论基础。

Abstract: Environment color as a physical signal may affect the reproductive behavior of insects, further affecting their population structure and dynamics. In the present study, we investigated the spawning habits and fecundity of the important predator, the seven spot ladybird beetle (Coccinella septempunctata), under different environmental colors in laboratory conditions. The results showed that C. septempunctata tend to lay eggs in red environment and fecundity (620.67) was significantly increased as compared with the control (453.30). The egg hatching rate of C. septempunctata was about 80%, and showed no significant difference from the control. In addition, C. septempunctata laid eggs on paper (conical paper tube). The eggs oviposited on red (223.67), blue (269.33), yellow (199.00) and green (137.67) were significantly higher than the control (66.33). The results of our study provide some experimental evidence on the use of special environmental conditions to improve efficiency of ladybird mass rearing and egg collection.
