Dactylopius Opuntiae
''Dactylopius opuntiae'', also known as the prickly pear cochineal, is a species of scale insect in the family Dactylopiidae. Taxonomy ''Dactylopius opuntiae'' was first identified by Cockerell as ''Coccus cacti opuntiae'' after he collected it from cactus plants in Mexico in 1896. Later, it was considered a synonym of '' Dactylopius tomentosus'', and workers often referred to the same species by different names or used the same name for different species. De Lotto notes that it became common practice to call ''Dactylopius'' ''opuntiae'' a distinct wild cochineal insect from ''Dactylopius tomentosus'', even though their identity and status were never fully resolved. Eventually, in 1929, the species was classified as ''Dactylopius opuntiae'' by Cockerell. Description All species of the family ''Dactylopiidae'' have females with an oval-shaped body that is purple-red in color and covered in a white, cotton-like wax. This wax protects the body of the cochineal from heat, cold, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scale Insect
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as honeydew on which sooty mold tends to grow. The insects often have a mutualistic relationship with ants, which feed on the honeydew and protect them from predators. There are about 8,000 descr ...

Opuntia ×occidentalis
''Opuntia'', commonly called prickly pear or pear cactus, is a genus of flowering plants in the cactus family Cactaceae. Prickly pears are also known as ''tuna'' (fruit), ''sabra'', '' nopal'' (paddle, plural ''nopales'') from the Nahuatl word for the pads, or nostle, from the Nahuatl word for the fruit; or paddle cactus. The genus is named for the Ancient Greek city of Opus, where, according to Theophrastus, an edible plant grew and could be propagated by rooting its leaves. The most common culinary species is the Indian fig opuntia (''O. ficus-indica''). Description ''O. ficus-indica'' is a large, trunk-forming, segmented cactus that may grow to with a crown of over in diameter and a trunk diameter of . Cladodes (large pads) are green to blue-green, bearing few spines up to or may be spineless. Prickly pears typically grow with flat, rounded cladodes (also called platyclades) containing large, smooth, fixed spines and small, hairlike prickles called glochids th ...
