中文摘要:

以六斑月瓢虫Menochilus sexmaculataulata 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?）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。

英文摘要:

Take two ladybeetles Menochilus sexmaculataulata. Fabricius and Coccinella transversalis Fabricius as an example, we evaluated the phototaxistic behavior to differential light quality (wavelength), including light emitting diode (LED) and color sticky trap (Jiaduo?).The laboratory test showed that yellow ( 570 nm ) and white (polychromatic light) LEDs were significantly more attractive than other color LEDs (blue 461 nm, green 519 nm, red 650 nm); and the field colored test also showed that yellow sticky traps (579 nm) attracted more ladybeetles than other colors (black 486 nm, blue 487 nm, white 491 nm, gray 492 nm, cyan 492 nm, green 515 nm, red 618 nm, pink 625 nm, purple 578.67 nm)Comprehensive analysis of the ladybeetles phototaxistic reaction to differential LEDs and colored sticky traps, yellow ( 570 nm and 579 nm) was the most attractive color for ladybeetles, therefore, whenever used yellow sticky trap for monitoring or control insect pest should be considered fully the trapping effect to ladybeetles.
