摘要
斜纹夜蛾Spodoptera litura Fabricius是台湾甲腹茧蜂Chelonus formosanus Sonan的优势繁育寄主,为了获得更多斜纹夜蛾卵块用于大量繁育台湾甲腹茧蜂,以提高其田间生物防治效果。分别测定了斜纹夜蛾和台湾甲腹茧蜂成虫对6种不同颜色卡纸的选择及产卵行为。结果表明:斜纹夜蛾对不同颜色的选择趋性为蓝色>绿色>白色>红色>黑色>黄色,对蓝色卡纸的选择率最高,选择率为22.93%,但不同颜色的卡纸对斜纹夜蛾落卵量及产卵选择率的影响差异不显著。台湾甲腹茧蜂对不同颜色的选择趋性为绿色>白色>黄色>蓝色>红色>黑色,在绿色卡纸的引诱率最高,为28.00%;在台湾甲腹茧蜂产卵选择上,蓝、绿、白、黄4种颜色的产卵量显著高于红色和黑色。研究结果可为大量繁育台湾甲腹茧蜂及其寄主斜纹夜蛾提供理论参考。
Spodoptera litura Fabricius is the dominant host for breeding of Chelonus formosanus Sonan.To obtain more egg masses of S.litura for large-scale propagation of C.formosanus and enhance the field biocontrol efficiency,we investigated the color preference and oviposition behavior of both species toward six colored papers.Results showed that the preference of S.litura for different colors was blue>green>white>red>black>yellow,and the selection rate of blue cardboard was the highest,with a selection rate of 22.93%.However,there was no significant difference in either egg deposition quantity or oviposition preference across colors.The preference of C.formosanus for different colors was green>white>yellow>blue>red>black,and the attraction rate of green cardboard was the highest,at 28.00%.Oviposition by C.formosanus on the blue,green,white,and yellow was significantly higher than that on the red and black colors.These results provide a theoretical reference for opti-mizing mass rearing systems for C.formosanus and its host S.litura through color-based trapping strategies.
