Parsley wormThe parsleyworm is one of the most striking

insects in the garden. These bright-colored caterpillars have a fancy for parsley, dill and the occasional carrot. When disturbed, they project a pair of fleshy, smelly "horns," designed to scare away predators.

Parsleyworms are fairly easy to control, if you want to do that. They are conspicuous and are easily hand-picked. The caterpillars also are susceptible to insecticides, such as Sevin or Bacillus thuringiensis, and are naturally attacked by parasites

ArmywormPseudaletia unipuncta

Symptoms

Singular, or closely grouped circular to irregularly shaped holes in foliage; heavy feeding by young larvae leads to skeletonized leaves; shallow, dry wounds on fruit; egg clusters of 50-150 eggs may be present on the leaves; egg clusters are covered in a whitish scale which gives the cluster a cottony or fuzzy appearance; young larvae are pale green to yellow in color while older larvae are generally darker green with a dark and light line running along the side of their body and a pink or yellow underside

CutwormsAgrotis spp. Peridroma saucia Nephelodes miniansand others

SymptomsStems of young transplants or seedlings may be

severed at soil line; if infection occurs later, irregular holes are eaten into the surface of fruits; larvae causing the damage are usually active at night and hide during the day in the soil at the base of the plants or in plant debris of toppled plant; larvae are 2.5–5.0 cm (1–2 in) in length; larvae may exhibit a variety of patterns and coloration but will usually curl up into a C-shape when disturbed

Aphids (Willow-carrot aphid )Cavariella aegopodii

SymptomsSmall soft bodied insects on underside of

leaves and/or stems of plant; usually green or yellow in color; if aphid infestation is heavy it may cause leaves to yellow and/or distorted, necrotic spots on leaves and/or stunted shoots; aphids secrete a sticky, sugary substance called honeydew which encourages the growth of sooty mold on the plants
