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.
