摘要:
经调查,桑盾蚧在洛南县1 a发生两代,主要寄生于核桃幼树的主干、粗枝和2 a生以上枝条,当年生枝、叶柄、叶片少有分布; 40%杀扑磷乳油1 000倍液、1.8%阿维菌素2 000倍液、40%毒死蜱1 000倍液防治桑盾蚧效果较好,有效率都在80%以上,可在5月10-30日即一龄若虫盛期,每隔10 d喷1次,轮换用药,共喷药3次。
Abstract:
The investigation described the distribution and harm of Pseudaulacaspis pentagona in Luonan county The result showed that Pseudaulacaspis pentagona has two generations in one year and mainly parasitize in young trees of walnut, especially two year branches, few distributed in current leaves and twigs. Methidathion E.C.(40%)1000times solution, Abamectin(1.8%)2000 times solution and chlorpyrifos(40%)1000 times solution have significant effect, respectively, all over 80%. The spray can be conducted in May, the period of nymph, once every 10 days with the pesticides applied alternatively. Three sprays in all are fine.
