This study was designed to find out if the honey bee (Apis mellifera) and the honey be affected by diazinon. Methods: Six hives were purchased, 3 hives in Bandar-Abbas and remaining were considered for Meshkinshahr. Plants around the hive were sprayed with diazinon at a concentration of 2/1000. Sampling took place 15d after spraying, and diazinon residue was measured by the HP TLC. The study was conducted in 2017–2018. Results: The amount of diazinon residue in honey and honey bee was measured and compared with existing studies. The amount of diazinon residue in honey bee was found to be 0.017mg/kg in Bandar Abbas, and 0.005mg/kg in Meshkinshahr hives. There was nothing in honey.
