    生物方法:胭脂蟲(Dactylopius spp.)和仙人掌螟(Cactoblastis spp.)是兩個最重要的刺梨仙人掌生物控制劑。兩者攻擊仙人掌的方式完全不同。胭脂蟲會附著到植物外表,吸出水分。仙人掌螟是黑色和黃色條紋的蛆蟲,會鑽入植物內,吃掉它(北西雜草 2007)。仙人掌螟會把大約50~90顆黏膠狀的卵,產在仙人掌的刺上,幼蟲會鑽入肉掌或葉莖,從內部吞噬他們(Stiling 2002)。由於仙人掌螟的寡食性習性,能成功對抗Opuntia屬仙人掌所有物種,包括11種北美原生種(Julien and Griffiths 1998, in Stiling 2002)。
    澳大利亞釋放仙人掌螟Cactoblastis cactorum之後,金武扇仙人掌(Opuntia monacantha)的族群崩潰(Dodd 1940, in Stiling 2002)。在澳大利亞用仙人掌螟成功控制Opuntia仙人掌之後,南非,聖赫勒拿島,夏威夷,新喀裡多尼亞,巴基斯坦,肯尼亞和亞森松島也跟著使用。1913年胭脂蟲 ceylonicus被引入南非,並在幾年之內成功控制Opuntia仙人掌。1928年,毛里求斯引進兩種仙人掌螟Dactylopius ceylonicusDactylopius opuntiae,用來控制Opuntia vulgarisO. Tuna。1950年,毛里求斯也引進仙人掌蛾C. cactorum來控制O. vulgaris。1974年,亞森松島引進C. cactorum,企圖控制O. vulgaris(亞森松島保護中心)。 English

            摘要: This compilation of information sources can be sorted on keywords for example: Baits & Lures, Non Target Species, Eradication, Monitoring, Risk Assessment, Weeds, Herbicides etc. This compilation is at present in Excel format, this will be web-enabled as a searchable database shortly. This version of the database has been developed by the IUCN SSC ISSG as part of an Overseas Territories Environmental Programme funded project XOT603 in partnership with the Cayman Islands Government - Department of Environment. The compilation is a work under progress, the ISSG will manage, maintain and enhance the database with current and newly published information, reports, journal articles etc.
