abstract
This study was conducted to analyse spatio-temporal dynamics and the impact of rainfall and temperature on two beneficial insect-families in cotton farms in Côte d’Ivoire, Formicidae and Coccinellidae. They contribute to reduce the pest populations in the cotton farms. Data were collected in four localities treated with chemical vulgarized. Sampling, of rainfall and temperature data were collected respectively by direct counting, capture with mowing net, traps, rain gauges and thermo-hygro-meters installed. We have inventoried 7675 insects including 93% for the Formicidae and 7% for the Coccinellidae. Analysis of variance, showed that there is a significant difference in aboundance of Formicidae but there is no significant difference between the population of Coccinellidae. Rainfall and temperature have not affected the dynamics of beneficial insects populations. Knowledge of those beneficials insects is important to developt an integrated cotton pests control methods.
