»Aphys gossypii: There are several grass species
(Malvaceae, Curcubitaceae spp.) and woody species (ornamental, fruit trees
(citrus, mainly))
»Toxoptera aurantii: Attacks both ornamental and fruit
trees and shrubs, mostly citrus
Cultural measures:
Apply balanced
fertilizers , and avoid excess nitrogen
Chemical application:
Once non-parasitized aphids are detected, and provided that predators
are not present, chemicals fenitrotion, imidaclorprid or pirimicarb can be
applied
Note:
There are several natural enemies of the aphids (Chrysopidae
spp., Coccinelidae spp., hoverfles…) that can reduce aphid
population. Thus, chemical treatments not hazardous to the environment should
be selected
