7. Flea beetles (several species)
Small, dark beetles that jump like fleas when disturbed.
Host/Range: Most vegetable crops. Found throughout North America.
Damage: Adults chew numerous small, round holes in leaves; most damaging to young plants; larvae feed on plant roots.
Control: Apply floating row covers; repel the pests by spraying plants with garlic spray or kaolin clay; for a serious infestation, try repeated sprays of Beauveria bassiana or spinosad.
8. Tarnished plant bug (Lygus lineolaris)
Fast-moving, mottled, green or brown bugs, forewings with black-tipped yellow triangles. Nymphs: similar to adults, but wingless.
Host/Range: Many flowers, fruits, vegetables. Found throughout North America.
Control: Adults and nymphs suck plant juices, causing leaf and fruit distortion, wilting, stunting, and tip dieback.
Damage: Keep garden weed free in spring. Apply floating row covers; encourage native predatory insects; spray young nymphs with Beauveria bassiana or neem.
