The study was conducted with the objective of to evaluate the potential effects of widely used agro-chemicals on the health status of Apis mellifera scutllata in Sidama zone, Southern Ethiopia. Seven different agro-chemicals (2, 4-D, Agrothoate 40% Malathion 50%, pyriban48%, Diazinon 60%, Macozeb 80% and Pallas 45 OD) were commonly applied on various crops in the study area. The acute toxicity of these agro-chemicals to honeybees was tested via feeding, contact and fumigation. The mortalities caused by individual agro-chemical were compared with positive control Agro-thoate40% (Diamethoate) and negative control (honey solution and water). Acute toxicity analysis in the laboratory indicated that all tested agro-chemicals were found significantly toxic to A.m. scuttlata compared to negative control via feeding. Agrothoate 40%, Malathion50% EC and Dianznon 60% were highly toxic with 100% of experimental bee mortality, less than an hour. All agro-chemicals were statically significant toxic to honeybee when compared (P<0.01) standard insecticides and control group through all exposure rout. Therefore, proper utilization agro-chemicals are important to minimize poisoning of honeybee.
