چکیده مقاله:
Bumble bees are important pollinators in nature and greenhouse crops. In addition to this efficiency, they are used as vectors of microbial agents to control of pests and plant diseases in biological control. In the commercial production of these bees, a significant number of queens are always removed due to lack of mating in the laboratory. This study was conducted with the aim of investigating the effect of mating environment on reducing the number of virgin queens in laboratory and natural environment. Effective factors in mating, such as age of male and queen, ratio of queen to male, temperature, humidity, illuminance, etc., were optimally considered in the laboratory condition. 50% of the queens were selected for mating in the laboratory at a temperature of 23°C, illuminance of 2000-2300 lux, humidity of 40%, and 30% of them mated. The remaining queens (20%) were transferred in the natural environment with variable temperature of 23 to 28°C, illuminance of 10,000 to 45,000 lux, humidity of 10 to 30%. 10% of them mated, and in the end, 10% of these 50% remained virgin. Another 50% were selected for mating in the natural environment, of which 45% mated. The remaining queens 5% were transferred to the laboratory for mating, and none of them mated. A percentage of the virgin queens of the laboratory mated in the natural environment. But the opposite of this issue was not observed in this experiment. The results showed that the queen is more inclined to mate in the natural environment.
