自然变温有效积温模型研究及在日本松干蚧若虫发生期预测上的应用
Application of the effective accumulated temperature model in the forecast of the occurrence period of Matsucoccus matsumurae nymph under natural conditions
【摘要】 根据对日本松干蚧Matsucoccus matsumurae(Kuwana)发生期自然积温的分析,提出了自然变温条件下有效积温模型K=∑T-N×C(T≥C),并将N1=(C×N0+K-∑T)÷(T1-C)用于预测日本松干蚧若虫发生期,越冬若虫始见期K=5.767 8±15.825 6℃·d,C=7.989 7±1.151 2℃,高峰期K=111.022 8±163.838 4℃·d,C=6.899 2±5.986 7℃。
【Abstract】 Matsucoccus matsumurae(Kuwana) was raised and observed under natural conditions,the data about its developmental duration were recorded and analyzed.The effective accumulated temperature model was proposed and applied in the forecast of the pest.
