Remarks
- Systematics: Insects with the typical morphology of this species were designated by this name (De Lotto 1974, Pérez-Guerra & Kosztarab 1992). Chavez, et al. (2011) designated a biotype 1 with the morphological characteristics diagnosed for D. confusus combined with characteristics corresponding to D. salmianus. Field observations show that these insects promote changes in the color of cladodes and fruits, and when the insects are closely gathered at the trunk-stem and stem-fruit joints, these parts are damaged and may detach from the main plant body. The insects were localized within the altitude range of 1654 m to 2773 m.
- Structure: Colour photograph given by Gill (1993).
- Biology: The bionomics in Texas was studied and described by Gilreath & Smith (1987; 1988). Gill (1993) indicates that it prefers the flat-padded Platyopuntia cacti. Chavez, et al. found that in Mexico, D. confusus grows mainly on the cladodes of tree and shrub cactus forms and on their prickly pear fruits in a predominantly desert habitat with scarce vegetation and arenosol, within the altitude range of 1200 m to 2547 m, which is higher than the previously reported altitude.
- Economic Importance: This species has been introduced into five countries as a biological control agent for suppressing Opuntia weeds; became established in Australia (Dodd, 1940); was established for a time in South Africa (Dodd, 1940; Annecke & Neser, 1977). Gilreath & Smith (1988) proved that natural enemies play a role in regulating population level of this scale on Opuntia cladophylls in Texas, USA. Goeden (1978) discussed the use of this species in biological control of Opuntia spp.
- General Remarks: Description and illustration of adult female by Ferris (1955a), De Lotto (1974a), Perez Guerra & Kosztarab (1992) and by Gill (1993). Portillo (1995) distinguished between the fine cochineal species Dactylopius coccus and a group of wild cochineal species comprising D. austrinus, D. ceylonicus, D. confertus, D. confusus, D. opuntiae, D. salmianus, D. tomentosus and D. zimmermani.
