不同种类色板与添加物协同对槟榔园害虫诱集的初步效果

Preliminary effect of different color plates and additives on the trapping of pests in betel nut orchard

为筛选出适宜的槟榔园粘虫板种类,选择了3种粘板和4种添加物在槟榔园开展了粘虫板对害虫诱集效果研究。结果表明,黄、蓝、黄蓝混合粘虫板均可诱集到一定量槟榔园害虫,其中以黄板诱虫效果最佳,总诱虫量及对蓟马、黑刺粉虱和叶蝉等3种监测害虫的诱集效果均优于蓝板和黄蓝混合板。4种添加物对黄板增效试验结果表明,添加诱虫烯可显著提高诱虫总量,添加诱虫烯或蜂蜜水可显著提高对蓟马的诱集量,添加蜂蜜水可提高叶蝉诱虫量,各添加物均对黄板诱集黑刺粉虱无增效作用。对蓝板的增效作用结果表明,供试的4种添加物均可增加蓝板诱虫总量,其中以诱虫烯和蜂蜜水的效果较好,且两者之间无显著差异。各添加物中,仅糖醋液对蓝板诱集叶蝉起到增效作用,其余添加物对蓝板诱集蓟马、黑刺粉虱及叶蝉无增效作用。

In order to select suitable sticky plate in areca orchard,three sticky card(yellow,blue and yellow-blue mixed)and four additives were selected to investigate the effect on the adhesion of pest in areca orchard.The results showed that a certain amount of areca orchard insects could be adhered to different color sticky plates.Among them,yellow plate showed best trap effects,and the total amount of insects and the trapping effects on thrips,Aleurocanthus spiniferus and leafhoppers were all better than blue plate and yellow-blue mixed plate.The synergistic effect of four additives on yellow board showed that adding muscalure could significantly increase the total amount of trapped insects,while the number of trapped thrips could be significantly increased by adding muscalure and honey water.Addition of honey water could increase the number of leaf hoppers,and all additives had no synergistic effect on A.spiniferus.The synergistic effect of four additives on blue sticky plate showed that the total amount of trapped insects could be increased by all the four additives.Among them,the muscalure and honey water treatment showed synergistic effect,and there was no significant difference between them.Among the additives,only adding sugar and vinegar on the blue sticky plate solution treatment have synergistic effect on trapping leafhoppers,while the other additives had no synergistic effect on trapping thrips,A.spiniferus and leafhoppers.
