为深入了解桑皱鞘叶甲Abirus fortunei(Baly)取食行为机制,探索安全有效的行为调控技术,通过观察其在寄主和非寄主植物上取食行为的差异,应用“Y”型嗅觉仪测试其对寄主和非寄主植物叶片气味的嗅觉行为反应,分析了寄主植物主要养分与其取食量之间的相关性。结果表明,桑皱鞘叶甲雌雄成虫在24h内的取食选择率分别为70%和35%,其中70%以上叶甲偏向寄主植物桑树取食,对桑树嫩叶和老叶的平均取食量分别为0.21 g和0.19 g,二者无显著差异。桑皱鞘叶甲对寄主和非寄主植物叶片气味的嗅觉行为反应与对照差异不显著;其取食量与寄主植物叶片含水量、可溶性糖和蛋白质含量之间无明显相关关系。表明桑皱鞘叶甲的取食行为不受植物气味和主要营养物质的影响。
In order to understand deeply the feeding mechanism of Abirus fortunei (Baly) and explore the safe and effective behavioral regulation techniques, we observed the difference of feeding behaviors among host and non-host plants, and used “Y” -type olfactory The plant was tested for its olfactory response to the odor of the host and non-host plants, and the correlation between the main nutrients of the host plants and their food intake was analyzed. The results showed that the feed selection rates of male and female adults were 70% and 35% respectively within 24 hours, of which more than 70% were predominantly fed on mulberry trees, and the average feeding rates on young and old mulberry leaves The amount of 0.21 g and 0.19 g, no significant difference between the two. There was no significant difference in odor response between the host and non-host leaves compared with the control. The correlation between the feed intake and the leaf water content, soluble sugar and protein content of host plants was not significant. It showed that the feeding behavior of S. avermitilis was not influenced by plant odor and main nutrients.
