Weevils

The boll weevil (Anthonomus grandis) is a type of beetle that is known to cause severe damage to cotton crops. The boll weevil measures an average length of six millimeters. It feeds on the buds and flowers of the cotton plant.

Wherever flour is present, the beetle known as the flour weevil follows. Rather than whole grains, this beetle can only digest flour. These beetles are not actually weevils.

While it is true that the rice weevil is harmless in itself, it hurts human beings on a larger magnitude by compromising food supplies. What it lacks in stinging or biting, it makes up for in causing destruction on a potentially massive scale.

Acanthoscelides obtectus is the scientific name of the bean weevil, the farmers' scourge. Technically, they belong to the cadre of seed beetles and are not true weevils.

Commonly called the granary weevil, the Sitophilus granarius, or wheat weevil, holds notoriety for its destructive potential in agriculture. Historically, it is known as one of the most formidable pests.

The black vine weevil, Otiorhynchus sulcatus, is believed to be another species that migrated to the United States.

The rose weevil is a serious threat to all horticulturists. Its snout can drill through flower buds. These weevils cause irreparable harm by feeding on petals.

Pissodes strobi, or the white pine weevil, is a pest that infests pine and spruce trees.

True to its name, this pest infests cowpeas and stored soybeans. Cowpea weevils lay eggs on the stored beans thay they eat, and the larvae use the beans as food while they develop.
