摘要
本试验通过对四个不同苜蓿品种(系)进行蓟马危害点系数和蓟马取食行为进行观测研究获得以下结果:抗蓟马苜蓿新品系被危害点系数为0.26、阿尔岗金苜蓿的0.41、草原2号苜蓿的0.61、敖汉苜蓿的0.61;苜蓿不同品种(系)叶片表皮毛密度在10枚/mm2以上时与蓟马危害点出现的频率成负相关;叶片表皮毛密度在10枚/mm2以上时,抗蓟马苜蓿新品系的叶片表皮毛密度所占叶片面积的比例比其他品种大;蓟马在抗蓟马苜蓿新品系上取食,比起其他苜蓿品种上取食表现为爬行时间较长,取食时间较短,挖掘点数少,能吸取食物点数较少。
This experiment through observation researched the disease - carrying insect harm index and the thrips takes the food behavior for four different alfalfa varieties （strains） result to indicate that, The harmed the point -system of anti - thrips alfalfa new strains was 0.26,Medicago sativa CV. Algongion 0.41 ,Medicago varia Martin. cv. caoyuan No. 2 0.61 ,Medicago sativa L. cv. Ao-han0.61 ; When thrips on the anti thrips alfalfa new strain plants to feeding, compared with on other alfalfa varieties the crawling time was longer, Feeding time was short, the excavation points were few. can absorb food points less.
