Whiteflies are small, winged insects that belong to the Order Hemiptera which also includes aphids scales, & mealybugs. These insects typically feed on the underside of leaves by penetrating the tissue and removing plant sap with their “needle-like” mouthparts. Whiteflies can seriously injure host plants by sucking juices (sugars & carbohydrates) from the vascular system causing defoliation, wilting, yellowing, stunting, necrosis, and then death.

The leaves of shrubs infested with whiteflies begin to turn yellow before the leaves are dropped from the plant.

Defoliation & necrosis ( die back ) are one of the most obvious symptoms of a whitefly infestation.

When the foliage is disturbed the small, white gnat-like adult whiteflies can be seen flying from the foliage. The adult whitefly is a very small moth with a yellow body and white wings with a faint grey band in the middle of the wings. Immature stages (eggs and nymphs) can be found primarily on the underside of the leaves.

Prior to adult emergence, the nymphs are tan to light green discs with red eyes. The underside of infested leaves look like they are dotted with small, silver or white spots which are actually the empty “skin” of the pupae after the adult emerges.

Eggs which are usually laid on the underside of leaves hatch into a crawler stage. The crawler wanders around the leaf until they begin to feed.

From this point until they emerge as adults, they are immobile and remain in the same place on the plant. These feeding, non-mobile stages (nymphs) are usually oval, flat, and simple in appearance.

The life cycle of the whitefly , from egg to adult, requires 2 to 3 weeks in warm weather, but may take as long as 2 months under cool conditions. The number of eggs produced per female is also greater in warm weather than in cool weather. The rates of reproduction for whitefly vary with the host plant, but the average is 160 eggs per female (with an approximate range of 50 to 400), with female crawlers emerging from about two-thirds of the eggs. This high reproductive potential explains in part how whitefly populations can increase so rapidly

(1 female -> 100 females -> 10,000 females -> 1,000,000 equaling the approximate number of adult females resulting from three generations).

They do appear to be more active during the sunny daylight periods, and do not fly as readily during the early morning, late evening, or night hours.

Please monitor your plants for any signs of defoliation & infestation because it will be easier to manage the pest before it builds to high populations causing major damage & death to your beautiful plants. With One Two Tree Whitefly Injection program you never have to worry no more.

We have had great success with our preventative programs. If your plants have already been infested we can stop the defoliation & destruction of your trees .

Our highly trained technicians spray a contact insecticide on the foliage & a systemic drench of the root systems to provide protection from re-infestation
