This insect is a coccidia and live mostly in olive and citrus fruits in general, but still lives on other trees and herbaceous plants including: oleander, Judas tree, evonimo, mastic, Aral, palms, and pumpkin carduacee spontaneous. The olive tree pests, cover the branches, twigs and underside of leaves where the larvae are located along the main veins. The mealybug causes decay of vegetation, defoliation, dieback of twigs, fruit drop and poor fruit production. The larvae (juvenile stage of cochineal) is yellowish, and become darker during development.
The male is winged and rarely appears, the adult female, measuring about 5 mm and its body is completely covered by a convex shield of wax (in which eggs develop) with a drawn on H. The abundant sugary excrement produced by females and cause asphyxiation create various burns (lens effect), they also a strong reminder of food for ants.
Development Scale is favored in years with mild autumn and winter and summer not too hot and humid. Combating this is very harmful Rincote agronomic but also chemical.
The chemical method provides an action threshold equal to 5.2 nymphs per leaf, or even a female for every 10 cm of each branch. If you exceed the threshold, you are working with organo-phosphate and white oils (avoiding the use of the first for the high toxicity towards the insect fauna is also very useful, we prefer the latter for the opposite reason). The fight agricultural uses vigorous pruning and nitrogen fertilization rates.
