STINKBUGS

DESCRIPTION
Some stinking species of thumbtacks that are fed on the plants. The adults are of green, bronze-coloured color or greyish coffee. They measure from 12 to 18 millimeters and have form of shield. The eggs have form of barrel and are put in groups. The nymphs pass for five stadiums and change similar color are maturing. They can have showy colors. This species feeds and lives in many plants. They put his eggs in the fruit-bearing trees.

Also there is a predatory thumbtack, that can differ from others because it is of dark gray color with white spots.

BIOLOGICAL CYCLE
Invernan like adults under the undergrowth or bushes. They become active in April and feed of undergrowths and other plants of broad leaf so much inside like out of the garden. The females deposit the eggs in the plants hospederas. Some adults can fly to the trees and deposit his eggs. The nymphs can feed of the fruit but they do not cause economic damage, for what it is not necessary to realize any measurement of control. Nevertheless, the majority of the nymphs develop in different plants hospederas. At the end of the summer, when the vegetation of not cultivated areas dries off, the adults emigrate to the gardens causing damage, principally in the trees of the shores.

DAMAGES
The chinches puncture the fruit little before the crop. The sting cannot be visible, but the area about the prick sinks and often, is of dark green color. The flesh under the skin of the fruit is soft and spongy where the damage is. The damage is similar to the symptom of deficiency of calcium (" bitter pit "), though the difference consists of the fact that the damage by deficiency of calcium is located in the base of the fruit and the flesh is of color coffee, whereas the damage by the chinches frequently is located in the top report of the fruit and the damaged flesh decolora slightly.

NATURAL ENEMIES
Some species of wasps are parasitic of the eggs. The flies taquínidas the adults attack.

Not a pretty subject but a neat view of the little bug. The photo could be a little sharper.
