| 中文摘要: |
| 在陕西关中地区研究了苜蓿蓟马优势种群、种群数量、危害特征、田间消长规律等。结果显示:牛角花齿蓟马(Odontothripsloti)是优势种;蓟马主要危害第二、三茬苜蓿,7～8月份是苜蓿蓟马若虫的发生危害高峰期。选用高效氯氰菊酯、吡虫啉、艾美乐和围打蓟虱蚜4种药剂防效比较表明,高效氯氰菊酯的防治效果最好,持效期长,成本低。 |
| 英文摘要: |
| Thrips is one of the most harmful pests on alfalfa. The study has been conducted in mid part of Shaanxi to evaluate the dominant species, population, damage characteristics and dynamic variation of trrips. The results showed that Odontothrips loti is the predominant species; it mainly endangers the second and third cutting of alfalfa, especially during July and August; in the four insecticides applied to control alfalfa thrips, 5% cypermethrin is the best one with an ideal and durative controling effects and low cost. |
