| 摘 要： | 花生种苗期大黑蛴螬和花生生长期大黑、暗黑蛴螬的虫口密度(X)与减产率(Y)呈明显的直线正相关,其相关式苗期网池接虫为Y=0.7245 0.004X±3.3957(r=0.9520,n=39);同步模拟为Y=0.4452 0.0040X±1.3959(r=0.9661,n=28);接虫示范为Y=0.1360 0.0074X±1.5888(r=0.9800,n=4);生长期接大黑金龟甲卵为Y=1.2927 0.0042X±3.2704(r=0.8993,n=36);接暗黑金龟卵为Y=0.7308 0.0042X±2.1344(r=0.9568,n=32)。研究分析提出花生种苗期防治指标为三龄大黑蛴螬每平方米2头;生长期防治指标为每平方米大黑卵3粒,暗黑卵5粒。

| Abstract: | There were significant linear relations between the grub populations (X) of Holotrichia oblita (in seed-seedling stage and growing stage of peanut) and H. morosa (in growing stage) and the yield loss rates of peanut (Y).The regression equations of a series of experiments,namely,grub inoculation in caged basins(1),simutaneous modulation(2),grub inoculation in demonstration plots (3),egg (of H.oblita and H.morosa) inoculation in growing stage (4) & (5), were described res-pectively as follows:Y=0.7245+0.0040X±3.3957(r=0.9520,n=39) (1); Y=0.4452+0.0040X±1.3959(r=0.9661,n=28) (2);Y=0.1360+0.0074X±1.5888(r=0.9800,n=4) (3); Y=1.2927+0.0042X±3.2704(r=0.8993,n=36) (4); Y=0.7308+0.0042X±2.1344(r=0.9568,n=32) (5), The results suggested that the action thresholds were 2 (three instar)grubs(H.oblita)per square meter in seed-seedling stage and 3 (H.oblita) or 5 (H.morosa) eggs per square meter in growing stage. |
