Leaf Footed Plant Bug Many varieties ranging from dark brown to black. Sometimes called stink bugs because of the foul odor produced when handled. Kin (and often mistaken) to squash bug. Some species partial to citrus fruit. Cause chlorosis in leaves. Will puncture a tomato, then inject a toxin causing the fruit to appear to be rotting from the inside out. Difficult to control organically. Aggie-Horticulture recommends commercial sprays containing permethrin, cyfluthrin or esfenvalerate.
I found these three bugs in my garden.
Four Lined Plant Bug Attacks leaf crops and is especially a problem for herbs. Mints are a favorite food. Dark spots, often mistaken as fungus, appear on leaves where bug has been feeding. Leaves may eventually die. Usually the bug disappears when hot weather arrives. Only one generation per year. Eggs can overwinter in perennial plant stems. Control organically with insecticidal soaps.
Aphids Extremely prolific, aphids are one of the gardens most serious threats. Over 200 species are known. Eggs laid in fall hatch in spring. Single aphids are tiny, but feed in mass sucking plant sap. They target stressed plants as healthy plants have a natural immunity. A new generation of aphids can appear every two weeks or less in warm weather. Aphids will eventually kill a host plant by destroying leaves thus preventing photosynthesis. Look for aphids on the underside of leaves. Effective organic controls include strong blasts of water and oil based plant sprays. Ladybugs are aphids' natural predator.
