Abstract Imidacloprid is a commonly used systemic insecticide which can induce several sublethal effects. Previous research has not shown any increased mortality in bees that were fed with sublethal doses. However, there is very little research conducted with the focus on survival rate of honeybees in the field. The aim of this study is to assess the influence of imidacloprid on the survival rate of honeybees under field conditions. Honeybees from different colonies were administered a single dose of imidacloprid of 0, 0.07, 0.7, 7 or 70 ng per bee. From each concentration one group was kept in the laboratory to assess lethal effects and one group was returned to the hive to assess possible sublethal effects. The surviving bees were counted regularly during 4 weeks. Analysis has shown no difference in survival rate between treatments in the laboratory. There is a difference between the 70 ng treatment and the control group in the field (P
