There was a positive relationship between the uniformity degree of the piemarker distribution in field and attractive rate 在棉花和大豆的整个生长期间,苘麻对烟粉虱均有极显著的诱集作用,但不同播期苘麻的诱集效果差别明显。
2.
The attractive efficiency from single interplanting piemarker was 3 - fold and 7 - fold high as compared to the planting types of the strip interplanting and plot interplanting 在棉花和大豆生长早期,烟粉虱最先在早播的苘麻上发生,诱集效果达85 . 2 % ;中播和晚播苘麻对棉花和大豆生长中、后期的烟粉虱诱集效果显著,分别达到93 . 3 %和95 . 4 % 。
3.
The insecticide application of 25 % thiamethoxam wdg , 5 % fipronnil sc , 25 % buprofezin wp 10 % beta - cyperethrin lc , and 25 % phoxim lc on piemarker plants , showed different control effects on sucking insect pests in cotton fields 苘麻植株在田间分散程度和诱集效果呈正相关,单棵插花种植苘麻的诱集效果分别是片状种植和条带种植苘麻的7倍和3倍。
4.
Among the insecticides tested , 25 % thiamethoxam wdg and 5 % fipronnil sc gave best results in terms of maximum mortality of this pest in cotton and soybean crops . conclusion piemarker as a trap plant in cotton and soybean field can play an important role in the integrated management of b . tabaci 基于播种期、种植方式和配套合理的药剂防治的苘麻诱集方法对生态调控棉田和大豆田中的烟粉虱发挥了积极的作用。
