Prickly pears (mostly Opuntia stricta) were imported into Australia in the First Fleet as hosts of cochineal insects, used in the dye industry. [1] Many of these, especially the tiger pear , quickly became widespread invasive species, rendering 40,000 km 2 (15,000 sq mi) of farming land unproductive. [ 2 ]

However, dense populations of prickly pear still exist in cold and rainy areas, which are less favorable to the development of Dactylopius opuntiae. Subsequent introductions of Dactylopius opuntiae inside the Kruger National Park in the mid-1990s failed to control Opuntia stricta , confirming the importance of matching particular biotypes of ...
Common English names for the plant and its fruit are Indian fig opuntia, Barbary fig, cactus pear, prickly pear, and spineless cactus, among many others. [3] In Mexican Spanish, the plant is called nopal, a name that may be used in American English as culinary terms. Peninsular Spanish mostly uses higo chumbo for the fruit and chumbera for the ...
Opuntia species, known commonly as prickly pears, were first brought to Australia in an attempt to start a cochineal dye industry in 1788. Captain Arthur Phillip collected a number of cochineal-infested plants from Brazil on his way to establish the first European settlement at Botany Bay, part of which is now Sydney , New South Wales .
By 1862 prickly pear was growing in the Chinchilla district and spread rapidly in areas where land holdings were extensive and population relatively low. [1] Prickly pear was declared a noxious weed in Queensland in 1893. By 1900 approximately 10,000,000 acres (4,000,000 ha) were affected by prickly pear; an area which had extended to an ...
From the Report of the Prickly-pear Travelling Commission. In 1912, Johnston was appointed chairman for a committee, the Prickly-Pear Travelling Commission, formed to investigate control measures for the prickly pear cactus. In 1788, Governor Philip and the early colonists are credited with the introduction of the prickly pear to Australia. The ...
