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. |

paper wasps |
Polistes spp. |
Paper wasps (Polistes spp. and others) may be seen searching leaves for food. These wasps attack soft bodied insects, such as hornworms, and use them up to feed larval wasps being raised in their nests. These beneficial insects play a role in the natural control of several tobacco pests. Most people recognize these beneficials as the familiar "stinging" wasps which build paper nests or combs under the eaves of buildings and in dense vegetation. |

grasshoppers |
|
Grasshoppers [various species including the differential grasshopper, Melanoplus differentialis (Thomas) and southern red-legged grasshopper are ¾ to 1 inch long. They are greenish-gray to olive-green or reddish-brown with a yellowish underside. The hind tibiae are red with black spines. The differential grasshopper is 1½ to 2-inches long with a shiny, brownish-yellow color and black V-shaped marks on the outer face of the yellow femur. Immatures (nymphs) are similar but lack fully developed wings. Grasshoppers damage tobacco by chewing ragged holes in the leaves. Most species prefer other plants but will eat tobacco if their food supply is inadequate. Grasshoppers often migrate into tobacco fields from hay fields, pastures, and old fields, especially when populations are high during droughts and following hay mowing or other habitat modifications. |

Ventral views of the abdomens’ of both H. pakistanae and H. balciunasi showing the morphology of the external male genitalia. Note the cruciate or crossed macrochaetae in both species, a configuration that is not found in native Hydrellia species. The primary difference between the two introduced species is the size and shape of the macrochaetae. In H. pakistanae, the macrochaetae are smaller and needle-like in comparison to H. balciunasi where the macrochaetae are larger and spoon-shaped at the ends |
