1440104 tobacco flea beetle Epitrix hirtipennis Tobacco flea beetles, are major pests of tobacco. The are brownish black beetles about 1/16-inch long. Feeding by adults gives leaves a characteristic shot-hole appearance. They attack plants in the seedbeds almost as soon as they come up, often ruining entire plant beds. After transplanting, beetles become continue chewing holes into the leaves until the crop is harvested, weakening the plants and decreasing the value of the leaves. Heavy feeding on newly-set plants may cause stunting, resulting in uneven stands. The white, larvae burrow into the soil and feed on the roots of tobacco, cutting off the small roots and sometimes tunneling into the stalk.
1440108 Japanese beetle Popillia japonica Japanese beetles, occasionally feed on tobacco in groups, causing a skeletonization of the leaf. The beetles are less than 1/2- inch in length, shiny metallic green, with copper brown forewings. There are six tufts of white hairs on each side of the body near the outer margins of the wing covers. These adults usually emerge from the soil during late May. Their population peaks four to five weeks later. Feeding is the greatest on warm sunny days. A relative humidity below 60% retards flying and induces the insect to feed extensively. The larvae are white grubs that feed in the soil, devouring the roots of a large number of plants, especially turf grasses.

1402106 tobacco wireworm Conoderus vespertinus Wireworms are thin, yellow-brown, hard-bodies larvae of click beetles that reach ½ - ¾ inch in length. They hatch from eggs laid in the summer, feed on roots of tobacco and other plants, and spend the winter in the soil. The first sign of a wireworm problem may be an uneven stand caused by damage to stems of newly set plants. Plants should be dug up and checked for feeding scars and tunneling in the stem. Sod webworms cause similar damage but generally leave silken webbing on and within the damaged stems.
