whitefringed beetles |
Naupactus spp. |
Larvae of this pest overwinter in the soil and feed under ground on roots and stems of recently set tobacco. This feeding may cause wilting, stunting or uneven stands. Yellow-white, legless grubs with light brown heads are heavy-bodied, slightly C-shaped, and up to ½ inch in length. They are often found in the soil near damaged plants or in stems. |

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. |

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. |
