The cocoa tree is a very important plant in Côte d'Ivoire (formerly known as Ivory Coast) with a production of 2,15 million  tons. In spite of this performance, cocoa production is attacked by several pests of which the emerging ones are Pseudotheraptus devastans (Distant). These insects  attack  cherelles,  pods, gourmands and young shoots. This study aims to locate these pests and determine their importance in the different cocoa production areas. The device used is total  randomization. The leaching carried out in the orchard revealed the presence of P.devastans in all the cocoa producing districts. The means were 0,02 ± 0,00 to 2,35 ± 0,38 P. devastans  / tree.  The  districts of Sassandra-Marahoué, Comoé and Montagnes recorded  more  P.devastans.  However, the districts of Bas-Sassandra, Lagunes et Lacs had fewer P.devastans.

This paper focuses on identifying pesticides uses in the protection of cocoa tree. To do this, a survey was conducted among 129 randomly selected cocoa producers in the Daloa zone in Côte d'Ivoire. The results showed that 79.84% of the producers interviewed, use pesticides. Twenty-seven (27) pesticides were identified; among them, 24 were insecticides, 3 were fungicides, and two were not licensed. More than 50% of the insecticides used by famers were neonicotinoids combined with pyrethroids. None of the pesticides was termiticide although termite damage was cited as major. Fiftythree point four percent (53.4%) of producers store pesticides in their house. Empty packs and containers are abandoned in nature after being used by 96% of surveyed farmers, while 4% reused them. The results indicated that producers should be well sensitized on good agricultural practice.
