不同颜色色板对稻田害虫及天敌昆虫的诱集效果研究OA

[Objective]The paper aimed to study the trapping and monitoring effects of different colors palettes on the common pests and natural enemy insects of rice,and to screen and determine the optimal color palette materials suitable for trapping and monitoring the main target pests of rice to provide theoretical guidance and reference basis for the convenient,accurate,and efficient color palettes in monitoring major rice pests.[Method]During the occurrence period of common pests in rice,palettes of nine colors,including red,orange,yellow,green,blue,purple,white,black,and tender green,were selected to carry out comparative trapping and monitoring experiments on adult pests and natural enemy insects in rice fields,and to select the optimal color palette for trapping and monitoring the main target pests of rice.[Result]The total trapping of rice pests,natural enemy insects and non-target flies of rice in different color palettes were higher in yellow,tender green,and green palettes.For rice pests,the order of trapping quantity was tender green>green>yellow>blue>orange>purple>red>black>white;during the whole experimental period for trapping Sogatella furcifera,the green palette had the highest,and before the heading stage,the tender green palette had the highest,and there was no significant difference between them(P>0.05);for Cnaphalocrocis medinalis,the tender green palette was the highest,and there was no significant difference between the yellow and the tender green(P>0.05);adults of Chilo suppressalis could be trapped by tender green,blue and white palettes;the Parnara guttata was the highest trapped by the blue palette,and the purple palette was the highest in the peak period,and there was no significant difference among blue,purple,yellow and tender green palettes(P>0.05);among the rice leafhopper species,the black palette was the highest,with no significant difference compared to the orange,red,yellow,tender green,and purple palette(P>0.05);the yellow palette was the highest of winged aphids,and there was no significant difference compared to the green and tender green palette(P>0.05);for natural enemy insects,the order of trap quantity was yellow>blue>tender green>green>purple>orange>white>red>black;the order of benefit-harm ratio of rice pests was yellow>blue>white>purple>orange>green>tender green>red>black.Yellow,green and tender green palettes were relatively high in trapping non-target flies.[Conclusion]Considering the trapping of various major pests and natural enemies,and the influence of non-target interference,the tender green palette is the preferred,followed by green palettes,or combined with the lure characteristics of color palettes,swatches to specific target objects.
