摘要
为提升云南河口青柚品质,减少蚧壳虫为害,2023—2024年对云南河口县青柚园介壳虫分布、危害情况及天敌种类进行了调查。结果表明:河口县危害青柚的介壳虫主要有9种,分别为褐圆蚧(Chrysomphalus aonidum)、柑橘白轮盾蚧(Aulacaspis citri Chen)、柑橘粉蚧(Pseudococcus citri Risso)、红蜡蚧(Ceroplastes rubens Maskell)、吹绵蚧(Icerya purchasi Maskell)、糠片蚧(ParlatoriaPergandiComstock)、白蜡蚧(Ericerus pela Chavannes)、矢尖蚧(Unaspis yanonensis)、黑点蚧(Parlatoria zizy-phus),均为盾蚧科。其中,褐圆蚧发生普遍,为害程度最重,柑桔粉蚧和柑橘白轮盾蚧次之,其余种偶见或零星为害。青柚园介壳虫天敌主要包括捕食性瓢虫类,寄生性天敌膜翅目跳小蜂科,保护与利用这些天敌对青柚园介壳虫的生物防治具有重要意义。文章同时提出合理的综合防治建议。
To improve the quality of Qingyou pomelo in Hekou,Yunnan,and reduce the damage caused by scale insects,an investigation of the distribution,damage status,and natural enemy species of scale insects in Qingyou pomelo orchards in Hekou County,Yunnan,was carried out from 2023 to 2024.The results revealed that nine main species of scale insects,all of which belong to the Diaspididae family,damage Qingyou pomelos in Hekou County.They were Chrysomphalus aonidum,Aulacaspis citri Chen,Pseudococcus citri Risso,Ceroplastes rubens Maskell,Icerya purchasi Maskell,Parlatoria pergandi Comstock,Ericerus pela Chavannes,Unaspis yanonensis,and Parlatoria zizyphus.Among them,C.aonidum was the most widespread with the most severe damage,followed by P.citri and A.citri Chen,and the other species were only occasionally or sporadically damaged.The natural enemies of scale insects in Qingyou pomelo orchards include mainly predatory ladybirds and parasitic enemies of the Encyrtidae family(Hymenoptera).Predatory enemies are mostly ladybirds.Protecting and utiliz-ing these natural enemies is highly important for the biological control of scale insects in Qingyou pomelo orchards.Moreover,reasonable integrated control suggestions are proposed.
