THE POPULATION DENSITY AND BIOLOGICAL STUDIES ON OMMATISSUS BINOTATUS LYBICUS IN UAE

The insect Ommatissus binotatus lybicus is one of the most important pests on date palm trees in the UAE. The life cycle and the population density of two generations were studied for the first time in the field during a year in this country.
The results showed that the population density of the first generation was higher than the population density of the second generation of this insect and this differentiation may be according to the rates of temperatures and relative humidity during the year in the UAE, and according to population density of the eggs of this insect. According to this study we could minimize the amount of chemical pesticides which were used for control and the times of control as well.
