1. Are snails, locusts, and seven-star locusts all pests?

When the population is large, it can be devastating to crops.

The seven-spotted ladybug is mainly used as a natural enemy insect to control agricultural and forestry pests. It is not the seven-spotted locust, which may be a mistake. It should be the seven-spotted ladybug.

Although snails are not insects, they are mainly herbivorous and harm crops such as crucifers, so they are considered pests and beneficial insects.

Locusts, a large class of insects in the order Orthoptera, are important pests

2. Why are locusts, cockroaches, and nematodes called pests?

Locusts destroy crops and are considered agricultural pests; cockroaches live in human living environments, disturbing human lives, and carry more than 40 kinds of pathogens, so they are considered public health pests; nematodes live in water, and if they accidentally enter drinking water, they will affect human health.

Cicadas, borers, crickets, snails, and grasshoppers are definitely pests.

Aren’t beneficial insects and pests actually defined by humans? Beneficial insects are those that are beneficial to humans, and pests are those that are harmful to humans.
