Beekeepers in northern and central part of Côte d'Ivoire, who are generally farmers, complain about desertions and frequent collapses of colonies. The application of pesticides to protect crops against attacks from disease and predators could be one of the factors responsible for these collapses and desertions. The objective of this study was to investigate if the use of agrochemicals in cotton and cocoa plantations could be a constraint to beekeeping. An interview implicating 51 beekeepers-farmers from eight cocoa and cotton producing regions was performed. The main results showed that 22% of the respondents were women. The apiaries contained 8 to 334 beehives with an average of 105 hives per apiary. Among a total of 5372 hives, 1402 were colonized which represents 26% of the hives. Most of the pesticides: insecticides (50%), herbicides (13%) and fungicides (9%) were used in cotton and cocoa production. Among farmers, 51% were not aware of the negative impact of agrochemicals usage on beekeeping. Moreover, 69% of them assured that they are over applying these chemicals. Besides that chemical applications were done during flowering period. From all these results, one can state that the use of agrochemicals on cotton and cocoa production might cause the desertions of bee, the weakening and collapse of hives that were observed by beekeepers.European Scientific Journal March 2017 edition vol.13, No.9 ISSN: 1857 -7881 (Print) e -ISSN 1857-7431 43Keywords: Agrochemical, beekeeping, agriculture, desertion, impact RésuméLes apiculteurs ivoiriens, qui sont pour la plupart des agriculteurs, se plaignent de fréquentes désertions et effondrements des colonies d'abeilles. L'utilisation des pesticides en agriculture pourrait être un des facteurs de ces phénomènes. L'objectif de cette étude était de vérifier si l'utilisation des produits agrochimiques en production cotonnière et en cacaoculture pourrait expliquer ces observations. Il s'est agi d'une enquête auprès de 51 agriculteurs-apiculteurs issus des régions du nord et du centre de la Cote d'Ivoire. Les résultats obtenus indiquent que 78% des apiculteurs sont de sexe masculin et qu'on compte 5372 ruches soit environ 7 ruches par enquêtés. Parmi les ruches 1402 sont colonisées, soit 26 % des ruches en moyenne. Les produits phytosanitaires utilisés en cacaoculture et en culture cotonnière sont par ordre d'importance : les insecticides (50%), les herbicides (13%), les fongicides (9%) ; et autres (28%). Parmi les enquêtés, 51% ne savent que les produits phytosanitaires pourraient avoir un impact négatif sur la production apicole. En plus, 60% affirment utiliser ces produits à des doses au-dessus de celles préconisées. En plus de cela, les applications sont faites pendant la période de floraison des plantes mellifères ; période d'activité intense de butinage des abeilles. Ces résultats montrent que l'application des produits phytosanitaires sur les cultures de cacao et de coton pourrait être la cause des désertions et effondrements observés par les apiculteurs de ces r...

“…However, because of their nature, their physico-chemical, biochemical and toxicological properties, these molecules pose major risks to human health [1] and the environment [2]. In addition to accidental or voluntary acute poisoning, repeated exposure to pesticides can cause various human health disorders: neurological disorders [3,4], endocrine disruption, leukemia, reproductive disorders [5,6].…”

Repeated exposure to pesticides can cause a variety of human health problems, particularly among farmers. This work consisted in studying biochemical parameters and their evolution in cotton farmers exposed to pesticides. A longitudinal study was conducted during and after the 2018/2019 cotton season on a cohort of cotton farmers around the Bala hippopotamus pond in the department of Satiri. Biochemical parameters were measured during and after the crop year on the Architect ci 4100. The majority of the farmers had high uric acid (UA) and low blood sugar (Gluc) concentrations. A few had concentrations of Cholinesterase (ChE) (6.19%); Direct Bilirubin (BilD) (23.01%); Gamma Glutamyl Transferase (GGT) (8.85%); Alkaline Phosphatase (ALkP) (4.42%); Cholesterol (Chol) (4.42%); triglycerides (Trig) (4.42%); aspartate aminotransferase (AST) (4.42%) higher than normal and lower than normal albumin (Alb) (13.27%) and total protein (TP) (13.27%) concentrations. Analysis of the evolution of biochemical parameters showed that none of the producers had higher than normal ChE and TP concentrations. After the campaign, the number of producers with lower than normal values increased for AST, AlkP, Alb and Urea while those with higher than normal values increased for GGT, UA, Gluc, Chol, Trig and BilD. Also, a significant decrease in AST, ALT and creatinine (CreaC) concentrations and a significant increase in GGT and BilD concentrations were observed. The existence of some disturbances of biochemical parameters in farmers should encourage to test the hypothesis of a link between pesticide exposure and the appearance of biochemical disorders in clinical trials.

Evaluation of the impact of herbicides on maize was done through multispectral and multi-modal imaging and multi-spectral fluorescence imaging combined with statistical methods. Spectra containing 13 wavelengths ranging from 375 nm to 940 nm were derived from multi-spectral images in transmission, reflection and scattering mode and fluorescence images obtained using high-pass filters (F450 nm, F500 nm, F550 nm, F600 nm, F650 nm) on control maize samples and maize samples treated with Herbextra herbicide were used. The appearance of the spectra allowed us to characterize the effect of the herbicide on the maize pigment concentration. The fluorescence images allowed us to track the fate of absorbed energy and through PLS-DA and SVM-DA to discriminate the two leaf categories with very low error rates for the test, i.e. 4.9% and 2% respectively. The results of this technique can be used in the context of precision agriculture.
