1440101 tobacco wireworm Conoderus vespertinus Wireworms (various species) are the major soil insects attacking tobacco. The yellow to brown, hard-bodied larvae are slender and cylindrical. The adult is a click beetle. Wireworms hatch in the summer, spend the winter in the soil and are usually most destructive to newly transplanted tobacco. Wireworm larvae cut off small underground stems and roots and bore into larger stems and roots. They may be found tunneling in stems near the soil surface . Affected plants may become stunted or wilt and die within a few days. Tobacco following sod may be damaged by wireworms for one to five years because some species have long life cycles.

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.

1402114 Japanese beetle Popillia japonica Adult beetles are metallic green with copper-colored wings and tufts of white hair around the posterior end. They are 3/8 to ½ inch long. Adults appear during late spring and early summer and are most active on bright sunny days. They migrate into tobacco fields and often feed in groups on the upper leaves of scattered plants. Feeding holes are of moderate size and irregular or ragged, giving leaves a lacy appearance. Larvae are the grubs which feed in the soil on roots other than tobacco. They are about one inch long at maturity, white or grayish white with a reddish-brown head and are somewhat C-shaped.

1440098 vegetable weevil Listroderes costirostris obliquus The vegetable weevil, feeds as a larva and an adult, primarily at night. The adult is a dull gray-brown beetle, about 3/8- inch long, with a pale gray mark near the posterior end of each wing cover, forming an inconspicuous V-shaped spot. The pale green legless larvae have brown heads. Larvae may feed on tobacco in plant beds during early spring. Larvae may damage or destroy the bud and eat holes into the leaves. Larvae appear in spots and may damage a good size area. Because they feed mostly at night, it is difficult to locate them. However, the feeding damage is usually easy to see and should be used to determine the presence of this insect.

1402102 vegetable weevil Listroderes costirostris obliquus Larvae and sometimes adults may feed on buds and leaves in plant beds. Adults may occasionally attack newly transplanted tobacco, feeding on leaves and stems. Feeding holes are ragged and may resemble grasshopper damage, but vegetable weevils nearly always cause some stem damage.
1402010 tobacco wireworm Conoderus vespertinus Wireworm damage may first appear as stunted or irregular plant growth. Holes and tunneling in plant stems just below the soil line and scars on root surfaces often indicate wireworm or other insect feeding.
1468172 black dot spurge flea beetle Aphthona nigriscutis
1440109 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.

1402107 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.
