Abstract	FACTORS OF NATURAL CONTROL OF GREEN SCALE OF THE COFFEE IN THE YEAR OF 2006 Abstract: The green scale Coccus viridis constitutes curse of the coffee, mainly in seedlings and in plants and in parts of the dossal that receive low brightness as it happens in planting densely. The damages of this insect-curse to the coffee happen due to sap suction and introduction of toxins in the vascular system of the plants. Among the most important points for generation of programs of integrated handling of cochonilhas is the knowledge of the factors causadores of natural mortality of these insect-curse. One of the more appropriate research tools to reach those objectives is the ecological life tables which quantify the mortality happened in the populations of insects in each phase of your life cycle besides they make possible the determination of critical phases of mortality and of mortality factor-key. This work had like this for objective to determine the importance of the ecological mortality factors of C. viridis using life table. It was observed that in the first semester of 2006 there was high mortality of the C. viridis in the face upper of the leaves. The discharge mortality in the phase upper was due to the action of himenopteros parasitoids (100%) being of 0% the action of predators. The largest mortality in the phase upper owed action of himenopteros parasitoids on C. viridis happened in the phase ninfal (90%) with low parasitoides incidence on adults of this C. viridis (10%). During the phase ninfal of the C. viridis the largest action of himenopteros parasitoids happened in the second instar (75,62%).
