白背飞虱吸食水稻植株的韧皮部,影响其正常生长。近年来,由此而引起的水稻产量损失愈加明显。推广种植抗虫品种有效地阻止了飞虱在其上取食与建立种群,在防治此虫中发挥了十分重要的作用。水稻抗虫品种对白背飞虱产生的不良影响是多方面的。为了探索稻株韧皮部内营养成分对飞虱的影响,我们采用间接的方法分析了飞虱取食抗感稻株后分泌的蜜露中氨基酸的成分与含量。1 材料与方法1.1 蜜露的收集测定蜜露中游离氯基酸总量时选用的抗白背飞虱
White-backed plant louse infects the phloem of rice plants, affecting their normal growth. In recent years, the resulting loss of rice production is even more pronounced. The popularization and planting of insect-resistant varieties effectively prevented the feeding and establishment of populations on the planthopper, and played a very important role in the prevention and control of this insect. Rice insect-resistant varieties of whitebacked planthopper have many adverse effects. In order to explore the effects of nutrients in phloem on planthoppers in rice plants, we used indirect methods to analyze the composition and content of amino acids in honeydews secreted by planthoppers resistant to rice plants. 1 Materials and Methods 1.1 collection of nectar Determination of free dew in the total amount of free chlorine acid selected white-backed planthopper
