为有效控制日本松干蚧松干蚧[Matsucoccus matsumurae(Kuwana)]对松树的危害,对日本松干蚧进行了生物学特性观察与药剂防治试验。该虫在临沂市1年发生2代,以1龄寄生若虫在树皮缝隙、翘裂皮下和叶腋等隐蔽处越冬(越夏),5月中下旬越冬代达显露高峰期,6月底开始越夏,8月底越夏若虫开始显露,9月中下旬达高峰期;10下旬至11月上旬进入越冬状态。40%杀扑磷乳油和5%阿维·吡虫啉乳油对日本松干蚧防效较好,药后20天防效达90%以上。
In order to effectively control the damage of Japanese pine, Quercus mongolica [Matsucoccus matsumurae (Kuwana)] to pine trees, the biological characteristics and preventive tests of the pine sinensis were studied. This pest occurs in Linyi City for one year and takes the first instar nymphs to overwinter (summer) in the bark of the bark, subcutaneously on the bark and leaf axils, etc. The mid-to late-May Daihadda peak appears in mid- Summer, the end of August the summer nymphs began to emerge, reached the peak in late September; late 10 to early November into the winter. 40% kill phospholipid and 5% Avicel imidacloprid on the Japanese Songkuai good control effect, 20 days after the drug control effect of more than 90%.
