tobacco flea beetle
Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type)
Description: Adult beetles are present on tobacco throughout the growing season (both in plant beds and in the field). Damage is characterized by small, round holes that give the leaves a "shot-hole" appearance. Injury is especially severe on newly transplanted tobacco. The lower leaves of larger plants can also be heavily damaged, especially near the base of the leaves. Adult beetles are brown with black markings and fine punctures on their wing covers. They are about 1/16 inch long. Adults pass the winter in grassy areas, woodlots, and other favorable sites in and around tobacco fields. The larvae are slender, white grubs 1/16 to 3/16 inch long with brown heads. Larvae live in the soil and feed on and burrow into the roots of tobacco plants. There are 3 to 5 generations of flea beetles per year. Several other species may occur in tobacco.
