giant bark aphid |
Longistigma caryae |
The giant bark aphid is the largest aphid in North America. During December 2001 and through most of March 2002, an outbreak of this aphid was found covering about the eastern quarter of Texas. They mainly attacked oak trees, especially live oak and water oak. Natural enemies, such as lady beetles, played an important role in controlling aphid populations. During winter months when temperatures are cold, predator and parasite insects are not very active, and this may be the reason aphid populations became so large early in 2002. |

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. |
| 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. |
| 1626049 |
whiteflies |
|
Adult whiteflies are only about 1/16 inch long. Their two pairs of broadly rounded wings are covered with a white waxy powder. |
| 1626050 |
whiteflies |
|
Nymphs are small, non-motile, and nearly the same color as the foliage. |
| 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. |
| 1626006 |
aphids |
|
Aphid feeding often causes leaves to curl and become deformed. Once this happens, control is very difficult because aphids inside the curled leaves are protected from contact with the insecticide. |
| 1626007 |
aphids |
|
Aphids excrete a sugary waste produce called honeydew. Notice the clear drop on the left side of this picture. Ants, bees, and wasps collect honeydew for food. Black and brown fungi, appropriately called sooty molds, cover leaves and other objects below aphid colonies where honeydew collects. |

giant bark aphid |
Longistigma caryae |
As aphids feed, they excrete a sticky, clear liquid known as honeydew that often forms a sticky coating on automobiles, picnic tables, lawn furniture, and plants underneath plants where aphids are feeding. A gray-black, sooty mold soon begins to grow on the sugar-rich honeydew, and it not only blocks sunlight and disrupts photosynthesis, but it can damage the finish on cars, chairs, tables or other objects. |
| 1150115 |
giant bark aphid |
Longistigma caryae |
The giant bark aphid is the largest aphid in North America. During December 2001 and through most of March 2002, an outbreak of this aphid was found covering about the eastern quarter of Texas. They mainly attacked oak trees, especially live oak and water oak. Natural enemies, such as lady beetles, played an important role in controlling aphid populations. During winter months when temperatures are cold, predator and parasite insects are not very active, and this may be the reason aphid populations became so large early in 2002. |
