【摘要】：以六斑月瓢虫Menochilus sexmaculata Fabricius和狭臀瓢虫Coccinella transversalis Fabricius为例,研究了瓢虫对不同光质(波长)的趋光性反应。在室内分别测定了六斑月瓢虫和狭臀瓢虫对5种发光二极管(LED)光波的趋性,以及在田间挂板(佳多溲)测定了瓢虫对色板的选择趋性。室内测定结果表明,瓢虫对黄色和白色LED光波的选择趋性显著高于与其它颜色;田间挂板试验表明,黄色对瓢虫的诱杀作用最强。综合分析,黄色对瓢虫有强烈的吸引作用,建议在使用黄板进行田间监测和防治时应考虑对天敌瓢虫的诱杀作用。
[Abstract]:The phototaxis of ladybug Menochilus sexmaculata Fabricius and Coccinella transversalis Fabricius to different light quality (wavelength) were studied. The (LED) phototaxis of five light emitting diodes (LEDs) and the selectivity of ladybugs to color plates were measured in laboratory. The results showed that the selection of yellow and white LED light waves of ladybugs was significantly higher than that of other colors, and the field panel test showed that yellow had the strongest trapping effect on ladybugs. Comprehensive analysis showed that yellow had a strong attraction to ladybug. It was suggested that booby-traps of natural enemy ladybird should be considered when using yellow board to monitor and control the natural enemy ladybug in the field.
