tobacco flea beetle |
Epitrix hirtipennis |
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. |

green peach aphid |
Myzus persicae |
The green peach aphid is a pale green, soft- bodied insect that is found in clusters on the underside of tobacco leaves. The 1/16-inch long "plant lice" use their sucking mouthparts to remove sap from the plants. Feeding by large numbers of aphids results in thin, lightweight leaves that may ripen prematurely. The sugar rich "honeydew" excreted by aphids builds up on the leaf surface and supports growth of black, sooty mold. The honeydew may cause leaves to stick together and cure to a dark, off-color of poor quality. Green peach aphids may transmit viruses such as tobacco vein mottling virus through their mouthparts. Aphid populations build up after winged females fly into tobacco fields, usually during the middle portion of the growing season. They settle on the leaf to feed and give birth to living young. Large populations can build up in a short period of time due to their short life cycle and the occurrence of several generations during a growing season. |

tobacco aphid |
Myzus nicotianae |
Several species of aphids or plant lice feed on tobacco, but only the tobacco aphid commonly builds up large colonies. Winged aphids fly to plants in the bed or field and being producing wingless young (nymphs). Wingless, aphids are softbodied, pink to red, pale green to yellow-green, pear-shaped, and only about 1/16 inch long when full grown. Most aphids are wingless even as adults, but darker, winged forms may also be produced. Aphids have beak-like mouthparts through which they suck plant juices. In addition, they produce a sticky waste product, honeydew, on which sooty mold develop. As a result of these factors, both yield and quality may be reduced. (This and other species of aphids may also transmit certain virus diseases.) Infestations are characterized by the presence of aphids (mostly on the underside of upper leaves), shiny or greasy honeydew deposits on the upper surface of leaves, and sooty mold. In recent years, the red (pink) form of the tobacco aphid has become much more prevalent than the green form. |

tobacco thrips |
Frankliniella fusca |
Tobacco thrips may cause damage to tobacco, especially during dry years. These slender yellow-to-brown insects are about 1/25 inch long. Adults have four very narrow, featherlike wings. Adults and nymphs suck sap from the leaves producing gray to silver feeding marks primarily along the veins of the lower leaves. The leaves also become peppered with minute black spots. The underside of midribs may be damaged. Heavy infestations cause the foliage to turn yellow, as seen here. |

aphids |
|
Aphids feed in colonies. They have plump, pear-shaped bodies and two tubes, or cornicles, which project like exhaust pipes from their abdomens. |
| 1626033 |
euonymus scale |
Unaspis euonymi |
Enonymus scale has two to three generations per year and can build up until whole plants are covered by scales. |
| 1626034 |
euonymus scale |
Unaspis euonymi |
Male and female enonymus scales are so different in appearance that they are often mistaken for different species. The males are small, narrow, and white and occur primarily on the leaves. |
| 1626028 |

Due to premature needle drop, infested plants become thin and a crust of sooty mold covers twigs and remaining needles |
| 1626036 |
obscure scale |
Melanaspis obscura |
Primarily found on oaks, this pest causes dieback of branches, limbs, and sometimes entire trees. Inexperienced observers often mistake these scales for flakes of bark even at close range. |

white peach scale |
Pseudaulacaspis pentagona |

Lilac, willow, apple, and dogwood are among over 100 plants known to be hosts of this pest. |
| 1626048 |
whiteflies |
|
Whiteflies often go unnoticed even when they occur in large numbers, because they congregate on the underside of the leaves. When the leaves are disturbed, the adults fly about, but they quickly settle again when the disturbance has passed. |
| 1626053 |
psyllids |
|
Some species are serious pests, but many are simply nuisances because the honeydew they produce leads to unsightly crusts of black sooty mold. |
