摘要
栗链蚧雌成蚧次年腹下幼蚧出现高峰期在５月１２日、５月１８日及６月８日。采用４０％氧化乐果１０００倍液＋４０倍机油乳剂进行全株淋洗式喷雾，于４至５月初和５月中下旬及６月上中旬各喷药１次，可有效地防治越冬雌成蚧，降低当年幼蚧基数和制止第１代第一龄幼蚧的传播及为害，达到全年控制和消除栗链蚧危害的目的。
The 1st generation Asterolcanium castaneae breaks out in 12th May, 18th May, and 8th June respectively. Spraying the entire tree with 40% Rogor (1000x) added with machine oil emulsion (40x) in late April and early May, mid and late May, and early and mid June respectively will effectively control this pest for the whole year.
