黄色粘虫板设置高度和密度对马铃薯害虫诱杀效果的影响

On the Trapping Effect of Setting Height and Density of Yellow Sticky Traps on Potato Pests

为确定不同悬挂高度及密度黄色粘虫板对马铃薯害虫的诱杀效果,设置10,45,80 cm等3种悬挂高度及270,360,450块/hm^(2)等3种悬挂密度共组成9种处理组合,比较各处理间粘虫板对马铃薯主要害虫的诱杀效果。结果表明,粘虫板诱集到的马铃薯主要害虫有蚜虫、潜蝇、种蝇和叶蝉等。不同悬挂高度、密度的组合粘虫板对马铃薯主要害虫的诱杀效果存在显著性差异,其中对蚜虫的诱杀效果最佳组合为10 cm+270块/hm^(2),对潜蝇的诱杀效果最佳组合为80 cm+360块/hm^(2),对种蝇的诱杀效果最佳组合为10 cm+270块/hm^(2),对叶蝉的诱杀效果最佳组合为10 cm+270块/hm^(2)。建议使用黄色粘虫板10 cm+270块/hm^(2)的组合对马铃薯田害虫进行防控。

In order to determine the trapping effect of different hanging heights and densities of yellow sticky traps on potato pests,nine combinations were designed with three suspension heights of 10,45,80 cm and three suspension densities of 270,360,450 blocks/hm^(2) to compare the trapping effect of yellow sticky traps on potato pests among different treatments.The results showed that the main pests of potato caught by yellow sticky traps were aphididae,agromyzidae,delia platura and cicadellidae etc.There were significant differences in the trapping effect of the combined yellow sticky traps with different hanging heights and densities on main potato pests,among which the combination with the best trapping effect on aphididae is 10 cm+270 blocks/hm^(2),the combination with the best trapping effect on onagromyzidae is 80 cm+360 blocks/hm^(2),the combination with the best trapping effect on delia platura is 10 cm+270 blocks/hm^(2),and the combination with the best trapping effect on oncicadellidae is 10 cm+270 blocks/hm^(2).In conclusion,the combination of yellow sticky traps 10 cm+270 blocks/hm^(2) is the best to control pests in potato field.
