Abstract

The present study has been carried out in order to determine the Entomofauna of four different Agroecosystems from the study area, northwestern Algeria. Regular sampling was done using the Barber pitfall trap and the sweep net in addition to visual observations in the field. Nine (09) taxonomic orders of Insects was identified from the four studied environments. It varies from one Agroecosystem to another. Coleoptera and Orthoptera were the most represented in terms of both species and numbers. Entomofaunal Diversity was more important in un-cultivated fields (Diversity index = 4. 15 bits, equitability = 0. 89) than in arable fields (index ranging from 1. 68 to 2. 87 and a equitability between 0. 41 and 0. 72). Limited bioDiversity in cultivated areas was the consequence of insect communities’ interactions disturbances caused by agricultural practices in these environments. Therefore, it is important to reduce these disturbances in order to enhance food resources, habitats and overwintering sites for Insects. This will ensures sustainable entomological Diversity, thereby increasing the role of biological control in pest management systems.
