Explanation

Scorpions and spiders are natural predators that feed on insect pests, making them effective biological control agents. They help maintain ecological balance by preying on harmful insects without the need for chemical pesticides. The other pairs are either not predators (parrots, bees) or not typically used for pest control (dragonfly, wasp, kites, locusts).
