Video: Aphids in motion
Aphids are small, soft-bodied insects with long, slender mouth parts that they use to pierce stems, leaves, and other tender plant parts and suck out plant fluids. Almost every plant has one or more aphid species that occasionally feeds on it. Many aphid species are difficult to distinguish; however, identification to species is not necessary [...]

Florida Wax Scale #4
Wax scale females feed and develop through three immature stages (first, second and third instars) before becoming adults, producing eggs and dying. When removing individual adult female scales from leaves at certain times of the year, hundreds of eggs will pour out of their body cavities (Fig. 2). In Texas, the Florida wax scale has [...]

Florida Wax Scale #3
First stage (instar) nymphs, called crawlers (Fig. 3), hatch from eggs over a period of 2 to 3 weeks and crawl to and settle on leaves, twigs and stems of host plants – thereby spreading the infestation. Read more about Florida wax scale and download the accompanying publication at our sister site, Landscape IPM.

Florida Wax Scale #2
Florida wax scale eggs are oval and reddish-orange and fill the cavity underneath the bodies of dead or mature adult female scales. First stage (instar) nymphs, called crawlers, hatch from eggs over a period of 2 to 3 weeks and crawl to and settle on leaves, twigs and stems of host plants – thereby spreading [...]

Florida Wax Scale
Although hollies have historically been a good choice as landscape plant species and are well adapted to the environmental conditions in Texas, the situation has changed over recent years. More and more landscape hedges of hollies (Ilex sp.) throughout the eastern half of Texas and the southeastern U. S. are becoming infested with the Florida [...]

Pecan black aphid
The pecan black aphid is a pest of pecan. While feeding, the black pecan aphid injects a toxin that causes the leaf tissue between major veins to turn bright yellow. These damaged areas, up to 1/4 inch across, turn brown and die. Infested leaves soon fall. Premature defoliation reduces nut fill and the following year’s [...]
