Crop damage in agriculture is caused by several threats, including pests or bio-aggressors, organisms that have been destroying cultivated or stored crops for about 10,000 years. This paper looked at the biodiversity of these organisms in a citrus orchard and a field of annual crops (maize, tomatoes and cassava) in the locality of Meyomessala (region of south Cameroon). After sampling in three batches of 100 m2 each of the two 2000m2 fields, captures, counts, and valuation of the severity of pest attacks on the aerial parts of the crops were carried out. Ecological indices were estimated using the Shannon Weaver method; as well as Pielous equitability.
