Identification of beneficial insects and/or pollutants in a field for crop plants

The present invention relates to the identification of beneficial insects and/or harmful organisms in a field for crop plants.The presence of a species in the field is captured by one or more sensors. One or a plurality of suggestions is/are generated as to which species it could be. Based on one or more models, the probability that the detected species could be a proposed species is calculated in each case. The site at which the species is detected, the detection time and preferably further parameters that affect the presence of the proposed species in the field are included in a model. The expressive capacity of the sensor or sensors is increased by means of the modeling.
