ABSTRACT

We undertake in this work a qualitative descriptive study of Heteroptera fauna in the moroccan rice farming which is totally practiced in the lowest region of the Gharb plain due to the favorable climatic and soil conditions. The systematic study stand at 10 stations covering the entire paddy rice during the two campaigns of 2014 and 2015. 30 species distributed in 10 sub-families were identified in the study area with a predominance of predatory species which have an interest against the proliferation of living species at the expense of rice plant. The biotypology study of this population demonstrated the presence of 3 principle species groups which have spatio-temporal distribution despite of the short period of the study imposed by the imperative of submersion period. Those groups are: summer species, autumnal species and species which have large distribution spectre along rice growing. Therefore, ricefields agrosystem has a structure, dynamics and evolution which correspond to that of natural lakes where the impoundment is shorter or longer during the year. Associated with biotic conditions, the hydrological cycle of rice, temperature and oxygen levels affect the distribution, occurrence and abundance of species.
