Aphid help for Steve
<Picture>
Description:
Clusters of pear-shaped green or black or purple etc. insects with long
antennae in front and 2 short "tailpipes" at the rear are found on tender
shoots and branch tips of plants. Some have wings. Empty white skins are
noticeable amongst the insects. They pierce and suck sap out of the plants
causing them to discolour, wilt or deform. Aphids can't metabolize all the
sugar and will secrete "honey-dew" which attracts Ants. A black fungus
("Sooty Mold") may grow on this "honey-dew. Some Aphids cause galls (on
Spruce), others cover themselves with white or grey wax (Woolly Aphids).
Life cycle:
Aphids overwinter as eggs. In Spring newly hatched insects are all female.
These will give birth continuously to live nymphs as many as 10 per day.
When crowded out some will develop wings and fly off to "greener pastures".
In the Fall when temperatures go down some males are produced. These mate
with females who lay eggs on plants and trees for overwintering.

Solutions
------------------------------------------------------------------------
Prevention:
Garlic, Chives, Anise, Coriander, Nasturtiums and Petunias will repel
Aphids. If Nasturtiums do attract Aphids then the soil may be too acid and
should be "sweetened" by adding lime.
Mint may discourage Ants as these insects will "farm" Aphids and protect
them from predators.
Anticipation:
Dormant Oil in the Winter will kill overwintering eggs on trees and shrubs.
Physical Control:
Water will wash Aphids off the plants. They will not crawl back on by
themselves but Ants will carry them and put them back.
Sticky barriers around the stems will help prevent this.
Remay cloth will prevent flying Aphids from landing.
------------------------------------------------------------------------
Biological Control:
Lady Beetles and their larvae will eat Aphids, as many as 2400 in their
lifespan. Green Lacewings (devour up to 100 per day), Aphid- Midges (orange
larvae), Spiders, Assassin Bugs and SoldierBeetles are also beneficial.
Chalcid and Braconid Wasps lay their eggs on Aphids, that hatch into larvae
who tunnel into their host.
------------------------------------------------------------------------
Later's:
Latox Systemic for Ornamental Trees and Shrubs, especially Roses. Mix 6 mL
in 1 L of water (1 tsp/quart) and spray plants and both sides of leaves
thoroughly.
Diazinon Insect Spray and Malathion 50 are good controls on Vegetables and
Fruit Trees.
Rotenone Dust contains a natural (botanical) insecticide and can be dusted
on vegetables up to 1 day before harvest.
Rose Dust, Rose & Flower Insect Killer and Tomato & Vegetable Insect Killer
are all Ready-To-Use and contain pyrethrum (also a botanical insecticide).
For House Plants use House Plant Insect Killer, or House Plant Bug Killer
indoors.

When using pesticides always read the entire label on the container and
follow the directions.
