To determine which one of the following insects does not undergo the stage of egg, larva, pupa, and adult, we need to have some basic knowledge of insect life cycles.

Most insects go through a life cycle consisting of four stages: egg, larva, pupa, and adult. However, there are some insects that undergo incomplete metamorphosis, where they have three stages: egg, nymph, and adult. Nymphs resemble adults but are smaller and lack fully developed wings.

Now, let's analyze each option:

A. Wasp: Wasps undergo complete metamorphosis, meaning they go through all four stages - egg, larva, pupa, and adult.

B. Locust: Locusts also undergo complete metamorphosis. They start as an egg, then hatch into a nymph (which is similar to a larva), then go through several nymphal stages called instars, before finally becoming an adult.

C. Bee: Bees are another insect that undergoes complete metamorphosis. They start as an egg, then progress into a larval stage, followed by a pupal stage, and finally emerge as an adult bee.

D. Moth: Moths also have a complete metamorphosis life cycle. They start as an egg, hatch into a larva called a caterpillar, then undergo a pupal stage inside a cocoon or chrysalis before emerging as an adult moth.

From the given options, the insect that does not undergo the stage of egg, larva, pupa, and adult is B. Locust. Locusts have nymphs instead of larvae and do not undergo a pupal stage. They go through several nymphal stages before becoming adults.

Therefore, the correct answer is B. Locust.
