一些报导表明,植株氮含量的微小变化可影响。韧皮部取不的蚜虫之行为。桃蚜的种群参数与汤莱(Brussels Sprout)和烟草叶片中氮浓度成正相关。桃蚜的相对生长速率与酰胺(天冬酰胺+谷氨酰胺)、谷氨酸和丙氨统的总浓度成正相关,但与汤莱叶中的脯氨酸和氨基丁酸浓度呈负相关。本研究在于确定氮肥对马铃薯害虫种群参数的间接影响。特别是在于验证后述假说,即桃蚜的种群增殖率与叶片中游离氨基酸浓度成正相关。由于游离氨基酸浓度的增加,致使桃蚜在马铃薯下部叶片上的数量更
Some reports indicate that slight changes in plant nitrogen content can be affected. Phloem take aphids behavior. Population parameters of Myzus persicae were positively correlated with nitrogen concentrations in Brussels Sprout and tobacco leaves. The relative growth rate of Myzus persicae was positively correlated with the total concentrations of amide (asparagine + glutamine), glutamic acid and alanine, but negatively correlated with the concentrations of proline and aminobutyric acid in the leaves. This study is to determine the indirect effects of nitrogen fertilizer on potato pest population parameters. Especially in verifying the hypothesis that the population growth rate of the green peach aphid is positively correlated with the concentration of free amino acids in the leaves. Due to the increase of free amino acid concentration, the number of Myzus persicae on the lower leaves of potato is more
