摘要:作为为害柑橘的主要害虫之一，柑橘木虱的发生不仅对柑橘造成直接的危害, 同时还是传播柑橘黄龙病的主要媒介昆虫, 其发生分布与柑橘黄龙病的发生关系及其密切。在田间柑橘木虱种群数量大小决定着柑橘黄龙病发生的轻重{1}, 这也是柑橘黄龙病发生并蔓延的关键因素, 因此控制黄龙病的发生及蔓延,必须对柑橘木虱的田间发生规律进行研究,以便采取有效的防治措施{2}。九里香年抽梢次数比柑橘多,因此柑橘木虱的年世代数在九里香比在柑橘上多，种群数量也较大{3}。柑橘黄龙病树梢情紊乱, 其年抽梢次数比健树多, 幼年柑橘树抽梢次数也比成年树多, 柑橘木虱在黄龙病树和幼年柑橘上的世代数也较多{4}。研究其在不同寄主上生命表差异有助于更好了解柑橘木虱生长习性进而更好地防治柑橘黄龙病。

Abstracts: Citrus psyllid as one of the main pests pesticide citrus it happened, not only of citrus cause immediate harm, at the same time it still spread the media insects citrus huanglong disease, its occurrence distribution and citrus huanglong disease happened in the field have a close relationship, citrus psyllid population size determines the weight of the citrus huanglong disease happening, this also is citrus the spread of disease occurrence and huanglong key factors, therefore control huanglong disease outbreak and spread of citrus psyllid, must study occurrence regularity of the field, in order to take effective prevention measures. Nine times in the smoke tip than sweet citrus much, so citrus psyllid in nine in generations in more than in the citrus fragrance, population is bigger also. Citrus huanglong disease in disorder, its treetop feeling smoke often than rehabilitation tree much sought, youth smoking citrus trees than adult tree seeketh number are also{5}, citrus psyllid in huanglong disease of youth and citrus trees more also generations. Research in different host on the life tables differences, which helps better understand the citrus psyllid growth habit.
