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.

ThermophilicCampylobactersare major causes of gastroenteritis in human. The main risk factor of infection is consumption of contaminated or by cross-contaminated poultry meat. In Côte d’Ivoire, gastroenteritis is usually observed but no case of human campylobacteriosis has been formally reported to date. The aims of this study were to determine prevalence and antimicrobial resistance ofCampylobacter jejuniandCampylobacter coliisolated from chickens ceaca in commercial slaughter in Abidjan. Between May and November 2009, one hundred and nineteen (119) chicken caeca samples were collected and analyzed by passive filtration method followed by molecular identification (PCR). From these 119 samples, 76 (63.8%) were positive toCampylobactertests. Among the positive colonies, 51.3% wereC. jejuniand 48.7% wereC. coli. Of the 39C. jejuniisolates, 79.5%, 38.5%, 17.9%, 10.3%, and 7.7% were, respectively, resistant, to nalidixic acid, ciprofloxacin, amoxicillin, erythromycin, and gentamicin. Among the 37 isolates ofC. coli, 78.4%, 43.2%, 13.5%, 8.1%, and 0% were resistant, respectively, to the same antibiotics. In conclusion, we reported in this study the presence of highCampylobactercontamination of the studied chickens. Molecular identification of the bacteria was performed and determination of high resistance to antimicrobials of the fluoroquinolone family was revealed.

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.
