For adults emerged weight from the three types of pods, no significant difference was observed among them. Adult beetles measurement was also taken on the emerged insects from non-cultivated plants seeds; results are recorded on the Table 8. The pest damages peanuts as well as tamarinds. Stages duration was given when a cephalic capsule was found in the cell of the larva.

In addition to this factor, insect used variety and biotype can also influence this development period. The number of eggs laid by female varied from 2 to eggs in relation to the female lifespan. The choice of groundnut three-seed pods by females can be explained by a more important availability of feeding eerratus for larvae [9]. Results on Table 6 showed that eggs deposit was done regardless of pod type.
