危害仙人掌類和多肉植物的介殼蟲種類很多，主要有仙人掌蚧、粉蚧、長尾粉蚧、夾竹桃圓蚧(也稱長春藤圓蚧)等。以仙人掌蚧最為常見，它能危害仙人掌屬、量天尺屬、曇花屬、令箭荷花屬、蟹爪屬等幾十個屬的種類。仙人掌蚧繁殖快，1年可發生數代。它吸取植物汁液使植株生長迅速衰弱，嚴重時植株枯萎、莖節脫落。即使把蟲刮除，被害部位仍留下難看的黃白色，影響觀賞。粉蚧為害仙人掌類和菊科、景天科、machixiankedeng。jiazhutaoyuanjiezhuyaoweihailongshelankeduorouzhiwu，zhizhubeihaishi，shengchangyanzhongshouyingxiang。fenjiedengdepaixiewuhaiyoufameiyanbing，yingxiangshengchangheguanshang。youyileijiekechongjiaogenfenjie，zhuanmenweihaizhizhugenbu。yibanbuyifaxian，zhizhushouhaihoushuilingguangliangdebiaopituranshiquguangze，chengxianyichangdehuianse，rubucaiqucuoshi，youkenenghuidaozhizhizhusiwang。
