We propose to establish a study on the diurnal and nocturnal insect activity according to their specific distribution in both daily variations in three palm groves (Sahne Elmartome, Bouhmid and Zemla) in the region of Oued Souf during 6 months. To this end, we considered that such a study requires first, a work in different stations. The methods that are used during the sampling periods (Barber pots, Fauchoire net and light traps), allow capturing the maximum of existing insects. Thereby 2245 class individuals' insect distributed among 92 species are trapped in the day, where the order Coleoptera 43.03%, Diptera 25.9% and Hymenoptera 23.53% with more abundant but the other orders are the weakest. We noted a maximum diversity 6.66 bits, with a diversity index H' 4.79 equal to bits and equitability 0.71. Thanks to the night Trap 381 individuals and 35 species are caught, where Lepidoptera 47.77%, Diptera 32.01%. Coleoptera 13.89%, Neuroptera 3.41%, Hymenoptera 1.57% and Homoptera 0.78%. The same maximum diversity in the day 6.66 bits, with a diversity index H' 3.81 equal to bits and equitability 0.57.
