The invention belongs to the field of agricultural pest control technology, and specifically discloses a combined trapping method based on host selection behavior of citrus psylla. By using folic alcohol as olfactory attractant of citrus psylla, the composition is not only simple, but also has good attracting effect, and adopts strong chemotaxis light wave and airflow permeability to adult citrus psylla. The combination trapping of yellow-green net-like attractants and insect viscose can significantly improve the trapping effect of adult citrus psylla. It can be applied to physical trapping of male and female adults of citrus psylla, as well as to intrusion monitoring in potential distribution areas. At the same time, it reduces chemical control in agricultural pest control. At the same time, the citrus Psylla trapping device provided by the invention has the advantages of simple structure, easy operation, no need for additional realizing conditions, and is very suitable for field actual prevention and control.

一种柑橘木虱的组合诱捕组合方法
本专利技术涉及农业害虫防治
,更具体地,涉及一种柑橘木虱的组合诱捕方法。
技术介绍
亚洲柑橘木虱(Asiancitruspsyllid),又称柑橘木虱(DiaphorinacitriKuwayama)属半翅目Hemiptera,扁木虱科Liviidae,是当前柑橘最严重的病害—柑橘黄龙病的媒介昆虫。该虫具刺吸式口器,主要通过吸取柑橘韧皮部汁液,传播黄龙病菌,1年可发生数代,各代重叠发生。雌虫能产卵700粒,在夏季,卵期为4~6d,若虫各龄期多为3~4d,自卵至成虫需16~18d,成虫寿命达1个多月。成虫和若虫均聚集在柑橘嫩芽上从而导致黄龙病的发生。柑橘植株一旦感染黄龙病,就会出现柑橘叶片斑驳、叶脉革质化,果实品质及产量降低、味苦,严重的直至落果,最后导致树势衰败至叶片完全黄化、落叶、橘树全株死亡。目前,国内外对于柑橘木虱的综合防治进行了大量研究,以化学防治为主。柑橘黄龙病随着全球气候逐渐变暖,冬季平均气温呈显著上升趋势,从而造成木虱种群的扩大以及黄龙病发病的地理位置不断北移,使得各国政府和果农对于开发新的防治方法的需求更加迫切 ...
