Aphids are small (1 to 10 mm long) and pear shape. Infestations are often worse during wet cool days of spring; they are frequently feed on new growing shoots and leaves. Actively growing weeds also harbor aphids\u00a0and\u00a0may migrate over to favorite garden plants. Summer feeding aphids should never be counted out. Feeding aphids may spread a number of bacterial and virus diseases from sickly to healthy plants.<\/p>\n

Color varies by aphid species and\u00a0are\u00a0capable of changing their color. Common colors include green, dark pink, yellow, and black. Many are smooth and shiny, and a few are wooly or covered\u00a0with fluff.\u00a0Most aphids are wingless, but some may form wings a new aphid colony to find a new food source when plants they’re feeding on are in poor shape.<\/p>\n

Aphids do not possess chewing mouthparts. They don\u2019t\u00a0nip chunks out of leaves or stems. Instead they have\u00a0piercing or \u201cstylet\u201d mouthparts\u00a0to draw out the sap from\u00a0sugary phloem tissues. Plant damage shows up\u00a0as leaf curling, stunted growth, yellowing (chlorotic), or any combination thereof.<\/p>\n

Their reproduction rates are very rapid. Aphids can reproduce without mating. Aphids also molt 4 times before maturing as adults. The old flakey skins are frequently seen over\u00a0leaf surfaces. A wet or sticky honeydew deposit builds up over leaves and stems; later, black mold fungus\u00a0colonizes over leaf surfaces. The sooty appearance looks unattractive. The sooty mold may be partially hosed off.<\/p>\n

Several pesticides are effective against aphids in\u00a0a garden. Insecticidal soaps and oils kill aphids on contact.\u00a0Systemic pesticides like neonicotinoids provide longer activity, but may harm many beneficial insects such as bees and butterflies. Products containing Beauveria bassiana<\/em>, Azadirachtin (neem oil) and Endeavor (pymetrozine) control aphids\u00a0without harming most\u00a0beneficial insects.<\/p>\n

The soft bodied aphids have numerous natural enemies including ladybugs, lacewings, fly larva, wasps, true bugs. Parasitic wasps\u00a0 may be purchased and released to reduce aphid populations.<\/p>\n","protected":false},"excerpt":{"rendered":"
