Melon aphids (Aphis gossypii) are a common pest of plants in the genus Hibiscus. These 6/inch-long, yellowish-green to green-black, pear-shaped insects feed directly on the nutrient-rich juices inside the leaves, as well as on succulent new growth. Melon aphids tend to feed in clusters, and in numbers they can cause extensive damage to plants, including. Nervous system insecticides, such as malathion, Dursban (chlorpyrifos), and Orthene (acephate), are labeled for use on many shade trees and ornamental plants for aphid control. Take a copious amount (as many as you can collect) of the insect you wish to repel and grind up their bodies.
Insecticidal ControlUsually aphids are not dicult to control with insecticides. But, plants may become re-infested from adjacent areas Figure 2. Black citrus aphid on camelia. Figure 3. Healthy (yellow) and parasitized (brown/swollen) oleander aphids. PAGE 3 3throughout the year. For control, apply one of the suggested insecticides (see Table 1. Aphids are small (1⁄16–1/8 inch long), soft-bodied insects commonly called plant lice or ant cows. Virtually every plant has at least one aphid species that attacks it. These small insects are masters of reproduction and are often found in great numbers on stems or leaves. Some species even feed on the roots of plants. They range in color from green to brown, red, black or purple.
Aphids are tiny (2mm to 4mm) insects found on almost every kind of plant and fruit tree. Aphids can be red, black, brown or green. Because aphids can reproduce in seven days without mating, it isn't long before your plants and fruit trees become infested.

In dire circumstances, you may need dig up entire plants and throw them in the trash – not the compost pile – to slow the spread of infestation on your property. Types of Aphids.

Aphids feed by inserting thin mouthparts into the plant phloem and sucking out sap. There are so many species of aphids it is difficult to generalize their appearance. Aphids are globular and 1 to 6 mm long depending on life stage and : Steven Frank.
are labeled for use on many shade tree and ornamental plants for aphid control. As with oils and soaps, coverage is very important and a follow-up application may be necessary.
Be sure that the pl ant or crop t hat yo u ar e treat ing i s listed on the product label. Sevin, (carbaryl) is not effective agai nst many aphi d so it is generally no t. Physical (Mechanical) Control Aphid populations can be reduced by washing the terminals of sturdy plants, such as shrubs and trees, with strong water sprays from a garden hose.
Chemical Control (Outdoors) If no aphid predator or parasite life stages are present, and the level of plant damage is objectionable, control may be necessary.
STEP 1: Removal. If you discover aphids your garden, follow one of these three methods to get rid of them. Hose them down. If you spot a few aphids on your plants, the minor infestation can be.

Adding too much fertilizer, for instance, encourages the plants to be sappy, which attracts aphids. Check your plants all the time. If you believe that aphids are already affecting the plant, take advantage of the various control measures or get rid of the plant with significant damage.
Unfortunately, aphids are frequently detected when plants are in flower, at or near the time of sale, when effective control is most difficult to achieve.
Aphids are small (less than 1∕8 inch long), soft-bodied, pear shaped insects with long legs and antennae. There are many types (species) of aphids. If you want your garden to support the ecosystem, leave the Aphids alone.
Aphids do not damage Native plants, especially if the plants are not water stressed. Aphids are a crucial part of the food web. Beneficial insects such as ladybugs, hover-flies and green lacewings, specialize in eating aphids. They also do aphids do a lot of damage to many plants.
How do aphids damage plants. They also do considerable economic harm to farmers. Theirs activates affect crops in two ways. By sucking the sap aphids soon cause the plant to another; they can be responsible for spreading virus infections among crops.
In large numbers, they can weaken plants significantly, harming flowers and fruit. Aphids multiply quickly, so it’s important to get them under control before reproduction starts.
Many generations can occur in one season. The good news is that they tend to move rather slowly and aphid control is. Aphids like the low light levels and cool conditions of spring and fall.
They will attack all plant parts but prefer young, succulent growth. There are many species of aphids, some named after the plants they attack, such as pea aphids and peach aphids.
How to Get Rid of Aphids. Remove aphids by hand by spraying water or knocking them into a bucket of soapy water.; Control with natural or organic sprays like a soap-and-water mixture, neem oil, or essential oils.; Employ natural predators like ladybugs, green lacewings, and birds.; Grow the right plants that attract predatory insects, plants that repel aphids, and plants that "trap" aphids.
Aphids. Reproductive habits. Ants and aphids. Resources. Aphids are insects in the order Homoptera, also known as plant lice. Some 3, aphid species have been identified worldwide with 1, species found in North America, which includes some 80 species classified as pests of crops and ornamental have a distinctive pear-shaped body, and most are soft and green in color.

Credit for sources of information on ornamental and turf pest control and management must go to Land Grant University extension and research workers in the areas of entomology, horticulture, plant pathology, and weed science who continually work to maintain and update ornamental and turf pest management information.
Aphids: Aphids, also known as plant lice, are among the most destructive tree bugs. These plant-sucking insects feed on the sap of a tree or shrub. Their excrement, referred to as honeydew, is commonly mistaken for sap dripping from a tree’s canopy.
Many species of Aphids (sometimes called plant lice) occur on ornamental trees and shrubs in Pennsylvania. Certain species feed on foliage, others on twigs and branches, flowers or fruit, and some on roots.
They feed on both coniferous and deciduous plants. Effective control of Aphids has been a problem to homeowners and landscape managers for. Wrap the stems of other plants in tape and apply the product to the tape rather than the stem.

Solution to Aphids: Get Rid of Them Quick. Avoid using nervous system insecticides, such as malathion, Dursban (chlorpyrifos), and Orthene (acephate). They are labeled for use on many shade trees and ornamental plants for aphid control, but are not safe to use on cannabis.
Isolate infested plants from others and control the pests aggressively. For whiteflies, hang yellow traps coated with a sticky substance close to the tops of plants. Whiteflies are attracted to the color yellow, and once they land will be stuck and die.
Hand-crush small populations of young aphids and whiteflies. The safest and fastest way to control aphids is to spray them off your plants with a strong stream of water from the garden hose.
Aphids are such small, soft-bodied insects that even a good rainstorm can knock them off. Once aphids are knocked off a plant, they rarely climb back on.Understanding how aphids damage plants. An aphid infestation can develop rather quickly and considering the insects are rather mobile they can travel quickly from one plant to another.
In an outdoor garden, aphid colonies are usually tended to by ants which will feed upon the aphid honeydew, a sugary liquid that aphids secrete as they feed upon the sap of plants.
