Predation affects the population and behaviors of flower visiting insects and plant fitness, most studies on plant-pollinator interactions have neglect this factor. This study reported weaver ants prey giant honeybees under flowers, and tried to understand the role of predation process on important foraging insects by simulated experiments. The results showed that, weaver ants forwardly attack their prey in good position and capture giant honeybees, indicated predation is an important factor to the interactions of plants and flower visiting insects. Giant honeybees had the ability to perceive predation risk on flowers, and they leave the dangerous warning to other bees. The treated individuals fled away from risky inflorescence and plants, leaving the sign on the inflorescenceSignificantly lower foraging frequency was observed to the inflorescence where the bee has been attacked, and duration of foraging was also shorter than that of the control. The effect of simulated treatment disappeared quickly in few minutes. This study found no obvious defense behavior when honeybees were foraging nectar.
