Aphids - Leaves my be discolored,
Curled, smaller in size, Also a sticky substance may be on the leave
A Much Larger view of Aphids on a leaf, Full Color
Wipe or Wash off the aphids, Q-tips dipped in alcohol will work also. Orthene will also work
As for the gnats, they are a very common problem.
They can come into your house on your clothes, on your pets, through windows, etc.
They can also in introduced from your soil/mix
Whiteflies - Tiny white winged insects, on the
underside of leaves,
Bump the plant and they will fly around. Leaves my be mottled and yellow
Wipe or wash off with 'Q-Tip' dipped in alcohol, 'Orthene' will also control whiteflies, and sticky traps might help.
Mealybugs - White cotton like insects under leaves and in corners of stems where they attach.
For a few mealybugs use a 'Q-Tip' dipped in alcohol and remove all the bugs.
Check your plants carefully to get them all.
Eggs sacs may be present under rims or bottom of the pots, so check here also.
Again, 'Orthene' will control Mealybugs

You can easily miss Soil Mealybugs, since they look alot like "perlite"
Always check for them when repotting
For Soil Mealybugs you will need to DRENCH the soil
If not the bug will simply move to an area of soil that did not get treated
Chemical controls for Soil Mealybugs include:
Marathon, Merit, Malathion, Cygon, Diazinon, Orthene, Schultz Insect Spray,
Marathon is my insecticide of choice for soil mealybugs.
I use about 1/8 teaspoon per 4" pot. Mix into the soil and water.
I always use it when I repot each African Violet.
Merit works well. Use the wettable powder and mix 1/8t to a gallon of water.
Then spray your plants. Merit is a systemic insecticide also.
Scales - Stems or Leaves are covered with a
cushion like mass,
or brown or reddish-grey 'BUMPS' Leaves may also turn yellow or drop.
You can try to pick these off, or treat with 'Orthene'
Spider Mites - Leaves are turning yellow.
There will be webbing over flower buds, between leaves or under leaves.
If you look close enough you can see these moving around.
Again 'ORTHENE' will help, Treat weekly so you kill the newly hatched eggs.
Springtails - Little specks swimming in your reservoirs.
Look for products containing diazinon, permethrin, bifenthrin, or cypermethrin, Malathion
and controlled by drying up their environment
