枇杷赭室喀木虱对不同颜色粘虫板的田间趋性研究OA

To clarify the field tendency of loquat Cacopsylla fuscicella to different colored sticky boards,a field study was conducted during the spring and autumn shoot periods of loquat in 2024,when the pest is most prevalent,using a chess-board-pattern hanging board method.The results showed that the color of the sticky board was the main factor affecting the tendency of C.fuscicella adults,while the hanging orientation had no significant effect.Among the eight colors tested(yellow,green,red,black,blue,white,purple,and pink),C.fuscicella showed the strongest tendency toward yellow.The number of insects trapped by yellow sticky boards was significantly higher than that by other colors.The average number of insects trapped per board was 85.9 during the spring shoot period and 279.8 during the autumn shoot period.C.fuscicella is the main pest occurring during the spring and autumn shoot periods of loquat,and its adults show the strongest tendency toward yellow sticky boards.In practice,yellow sticky boards can be prioritized for the control or monitoring of C.fuscicella.
