为了比较斜纹夜蛾性诱监测与灯诱监测效果,揭示斜纹夜蛾种群数量长期运动规律和季节性消长规律,2006—2014年在临海城郊蔬菜基地应用性诱和灯诱方法对斜纹夜蛾进行逐日系统监测研究。结果表明,斜纹夜蛾时序性诱日量(YS)与灯诱日量(YL)呈极显著的线性关系。两者数学关系模型为YS=0.319 9YL+0.441 93(r=0.778 8**);年度种群数量(NS为年度性诱蛾量或NL为年度灯诱蛾量)运行轨迹与数值化年度(t)之间的数学关系模型为NS=12.019t2-340.62t+2517.2(r=0.837 9**;r0.05=0.602 1)或NL=7.905 8 t2-426.93t+4 488.7(r=0.820 9**;r0.05=0.602 1);季节性变化(MS为日性诱蛾量或ML为灯诱蛾量)动态与时序数值化日数(d)之间的数学关系模型为MS=-0.000 3d2+0.0641d-0.183(r=0.736 8**,r0.01=0.254 0)或ML=-0.000 8d2+0.158 2d+0.288 1,(r=0.776 9**,r0.01=0.254 0)。由此可知,应用性诱技术对斜纹夜蛾监测具有与灯诱监测同样的效果。2014年为探底之年,未来将进入新一轮运动周期发生为害。
In order to compare the long-term movement rule and seasonality of Spodoptera litura population induced by sex-induced monitoring and light-induced monitoring, the application of lure and lamp-inducing method to the vegetable base in Linhai suburb was carried out on Spodoptera litura Daily systematic monitoring study. The results showed that there was a significant linear relationship between the time-dependent amount of sun-lethal dose (YS) and the amount of induced light (YL). The mathematical relationship between the two was YS = 0.319 9YL + 0.441 93 (r = 0.778 8 **). The annual population (NS is annual annual moth or NL annual annual light moth) ) For the mathematical relationship between NS = 12.019t2-340.62t + 2517.2 (r = 0.837 9 **; r0.05 = 0.602 1) or NL = 7.905 8 t2-426.93t + 4 488.7 (r = 0.820 9 * *; r0.05 = 0.602 1). The mathematical relationship between the seasonal variation (MS is the number of daily induced moth or ML is the amount of trapped light) and the number of days (d) is MS = -0.000 3d2 + 0.0641d-0.183 (r = 0.736 8 **, r0.01 = 0.254 0) or ML = -0.000 8d2 + 0.158 2d + 0.288 1 (r = 0.776 9 **, r0.01 = 0.254 0). It can be seen, the application of luring technology on the Spodoptera lutea monitoring and luring the same effect. 2014 is the year of bottoming out, and will enter into a new round of sports cycle.
