Aphids

• Dust with flour. It clogs their pores and they
  die
• Encourage Aphid eating beneficial with planting
• Ladybugs fennel, Dill, Cosmos, Coreopsis, Tansy,
  Yarrow, Fennel, and even Dandelion
• Parasitic Wasps and Hoverflies Sweet Alyssum,
  Monarda, Bugleweed (Ajuga), Thyme, Lavender
• Lacewings Sunflower, Tansy, Cosmos, Dill, Yarrow
  
• They all like a source of water too...a shallow
  pan or plant saucer with stones works well

• In a ½ liter spray bottle, squeeze a small amount
  of liquid dish detergent and add approx. ½ to 1
  tsp. of crushed red hot chili pepper (finer the
  better). You can also steep some crushed red
  pepper tea to use in place of the powder/flakes.
• Once ingredients are added fill w/ warm water,
  cover the spray bottle and shake well.
• Spray onto leaves, stems, flowers and buds making
  sure to get the underside of leaves and between
  tender new leaves.
• They suck plant sap from mostly all small fruits
  and vegetables.

Cabbage maggot

• Cool temperatures and wet soil conditions at the
  time of egg laying are the main factors
  influencing the levels of cabbage maggot. Cabbage
  maggot infestations are more severe following a
  cool, wet spring. On the other hand, populations
  are generally lower in hot, dry years.

• Wasp and parasitic beetle that each attacks the
  pupae. In addition, vast numbers of maggot eggs
  are eaten by rove beetles.
• They bore into roots of the cabbage family and
  stunt or kill the crops.

Cabbage worm

• General predators that feed on cabbageworms as
  well as other pests are ground beetles, true
  bugs, syrphid fly larvae, spiders, lacewings,
  spined soldier beetles, yellow jackets, and paper
  wasps. Virus diseases can infect and decimate
  imported cabbageworm and cabbage looper
  populations.
• Larvae chew large holes in leaves of cabbage
  family plants and many other vegetable crops.

• Cultural and Physical Control
• Destroy crop debris after harvest.
• Remove weeds in the mustard family (wild
  mustard, wild radish, Sheppards purse, and
  peppergrass) from the area.
• Row covers prevent adults from laying eggs
  on plants.
• In small gardens, the worms can be
  hand-picked from plants

5
Cucumber beetle

• Predators and parasites that prey on Cucumber
  beetles include hunting spiders,Web-weaving
  spiders, soldier beetles, Ground beetles,
  Tachinid flies, Wasps, bats, and nematodes.
• Larvae feed on roots of corn, often killing
  young plants older plants are weakened and may
  topple easy. Adults feed on leaves and sometimes
  petals of squash family plants.

• Repellent plants Broccoli, calendula, catnip,
  goldenrod, nasturtiums, radish, rue and tansy. If
  you want to try marigolds to repel them use the
  more pungent varieties like African, French or
  Mexican marigolds. The more common marigolds may
  actually attract them, therefore could be used as
  a trap crop.

6
Flea beetle

• In healthy agro-ecosystems, there are populations
  of beneficial predators and parasites that work
  to control the number of flea beetles and other
  pests. One example is Microcotonus vittage
  Muesebeckc, a native braconid wasp that kills the
  adult flea beetle and sterilizes the female flea
  beetle.
• Adults chew numerous small round holes in leaves
  in most vegetable crops as well as many flowers
  and weeds.

7
Cutworm

• While there are pesticides which can control
  these insects, the non-industrial gardener can
  protect threatened plants (most often tomato,
  pepper, pea, or bean) by simply impeding the
  ground-hiding cutworm caterpillar from climbing
  the plant they hide in the soil near the plants
  and climb them at night.
• At night, they feed on the stems of plants near
  the soil line.

• To prevent this, one can
• Place a "cutworm ring" around the plant. It
  can be a can with both ends cut off, or anything
  similar, even a ring made of cardboard. It should
  be at least four inches high above the soil and
  go one inch below the surface. Some even use five
  gallon buckets with the bottom cut out, planting
  the seedling and bucket at the same time.

Garden symphylan

• To find symphylans, sprinkle about a quart of
  suspect garden topsoil into a bucket of water.
  The garden symphylans should float on the
  surface.
• They feed on the root hairs and rootlets and can
  sometimes cause crop failure.

• Or slice a potato in half, put it on your garden
  soil and cover it with a light proof container
  that doesn't get too hot in the sun, such as a
  white PVC end cap. Leave it out for a night or
  two, then quickly lift the container and examine
  the potato. If you have symphylans in your soil,
  the potato should be crawling with the tiny white
  creatures.
