Beekeepers in Tizimín have reported a significant die-off of bees, attributing the cause to the use of agrochemicals. A report from The College of the Southern Border (Ecosur) reveals that 38 apiaries and 789 hives in the region have been affected. The primary source of this contamination appears to be ranches with irrigation systems where corn crops have been grown from February through mid-March.
The townships most impacted include Chenkekén, San Pedro Juárez, Dzonot Mezo, Tixcancal, San Luis Tzuctuk, and Santa Clara Dzibalkú. The Ecosur study, which conducted seven tests on poisoned bees, found that four samples tested positive for fipronil, chlorpyrifos, and fipronil metabolites. The remaining tests revealed a combination of fipronil and endosulfan metabolites alongside the previously mentioned components. Beekeepers in the region had noted signs of intoxication in their bees six months prior, observing a gradual depopulation of hives and symptoms of disorientation and inability to fly in the bees.
The report also emphasized that acute pesticide poisoning led to the death of 30 percent of the bee population within a 48-hour period. Of the 789 affected hives, 536 suffered total damage and 233 sustained partial damage. The economic impact of this devastation is estimated at 4,371,700 pesos, taking into account lost work days, honey production, bee colonies, and pollination services. It's worth noting that this region of Tizimín has a history of such poisoning incidents dating back to 2018.
