: The honey bee obtains food from bee forage, which comprises crops grown in multi-hectare agricultural fields where various types of plant protection products such as pesticides are used. Some of these negatively affect the honey bee organism. In our research, we aimed to evaluate the effects of three pesticide groups: fungicides (tebuconazole), insecticides (acetamiprid), herbicides (glyphosate), and their mixtures on the functioning of honey bee workers ( A. mellifera carnica). Pesticides in various proportions and dilutions were added to sugar syrups and then fed to the bees. Mortality and food intake were recorded daily, while hemolymph analysis was performed after seven days of exposure. Food intake, mortality, and the results of various biochemical analyses differed between the experimental group and the control group receiving untreated sugar syrup. PPP’s mixture of glyphosate tebuconazole and acetamiprid is more toxic to bees than single pesticides. Certain protection products such as pesticides can disrupt the antioxidant and detoxification systems associated with immunity in honey bees. Consequently, honey bees experience weaker conditions and their proper functioning deteriorates. The results obtained from biochemical changes provide a basis for field studies.
