 Bad Mites: Two Spotted Spider Mites

 

 

Spider Mites are one of the most persistent pests for the indoor gardener.

 

 

Mites are tiny (about the size of a period {.}), and crawl on the underside of the plant’s foliage.

 

 

These mites are yellow, tan or clear in colour and have two black spots on each side.

 

 
Spider mite damage starts as yellow specks on the leaves causing yellow mottling . . . killing the leaves.

 

 
As the spider mite colony grows, webbing is present along the center vein on the underside of the leaves and in the new growth of the plant.

 

 
Mites use the webbing to crawl from plant to plant.

 

 
Bad Mites like it HOT and DRY.

 

 

Good Mites: Phytoseiulus persimilis

-
One of the fastest acting predatory spider mites.

-
It consumes 20 young and 7 adult two spotted spider mites a day!!!

-
Females are 0.5mm in size, red or orange in colour and pear shaped.

-
Males and young (nymphs) are much smaller in size and lighter in colour.

-
P. persimilis produces NO WEBBING.

-
Good Mites like it COOL and HUMID, optimal temperature is 20-30 degrees F (70-80 degrees C) and humidity of 70-80%.

-
At 24 degrees C (75 degrees F), good bugs will out breed bad bugs 2:1, but not at 30 degrees C (85 degrees F), it is the opposite.

-
Lower room temperatures to 24-27 degrees C (75-85 degrees F) and increase humidity; Bad bugs like it HOT and DRY!!!

-
Move fans off plants; it creates dry areas, aim the fans at walls or ceiling to get better air circulation.

-
Clean away all webbing with a soap spray and damp cloth.

Release of Predatory Mites:

-
Controlling bad mites with good mites will “INCREASE YOUR YEILD!!!”

-
Predatory mites are environmentally friendly and can be used up to the day of harvest.

-
IMPORTANT: Good bugs are eating the bad bugs so order enough:

If you have WEBBING: Release 10,000 P. persimilis.

To MAINTAIN: Release 2,000-10,000 P. persimilis as needed.

PREDATORS
Often the safest way to get rid of insects is to introduce predators. These predator insects eat or otherwise destroy the unwanted pests without affecting your plants. Once the pest population has been eliminated the predators die too because they have nothing left to feed upon. This process is now used by a majority of commercial greenhouse vegetable growers.

 

We offer a wide variety of preditor insects. Here are examples of some common insect pests and an efficient biological solution:
PESTS:
Fungus Gnat
Spider Mite
Whitefly
Aphid
or Sciarid Fly
Thrips

BIOLOGICAL SOLUTION:
Persimilis
Encarsia
Aphidoletes
Hypoasis
Cucumeris & Orius
Other predators are available upon request.

Fungus Gnats
I am Not a Fruit Fly or a Mosquito!!!
Do You Have Fungus Gnats?
Do you see small fruit fly-like insects flying around your plants/soil/cubes?
Are you over watering your plants or using a hydroponic system?
Do you find small worms in the soil/cubes of your plants?
YES, You Have Fungus Gnats!!!
Bad Bugs: Fungus Gnats
-
Fungus Gnats are small grey insects that look similar to fruit flies or mosquitoes, but are not. They are usually seen coming out of the very moist soil. Fungus gnats do not rest on the leaves of plants.
-
The adults live a very short time and do not feed, only mate. The females lay eggs in the upper part of the soil and these eggs hatch in 4 days.
-
The larvae are small white worms with brown heads and live in the first 1-2 inches of soil, or on roots they feed on roots of seedlings and eventually burrow in to the stems and leaves of the plants. The plants will begin to wilt when the damage is serious.
-
The adults can be trapped on yellow sticky cards. Lay the yellow sticky cards across your pots or as close as possible to the cubes.
Good Guys:
-
Nems – Steinernema feltiae (Beneficial Nematodes)
-
Best product to control fungus gnats and black vine weevil; NEMS.
-
Nems actively seek out the fungus gnat larvae in the soil/cubes and kill them.
-
The nematodes are applied to soil/cubes/rockwool/stone that is very wet with temperatures that are above 10 degrees C (50 degrees F). Nematodes are never added to the reservoir.
-
The nematodes are mixed with water and poured directly on the soil/cubes of the plants. They can be applied using ordinary spraying equipment or watering can.
Hypoaspis miles:
-
A small brown predatory mite that feeds on soil larvae and insects such as FUNGUS GNATS, springtails, THRIP LARVAE.
-
These mites survive for 7 weeks without prey
Helpful Hints:
-
Use NEMS and HYPOASPIS together for fastest and most effective control and don’t forget the yellow sticky cards to catch egg laying adults.
What is Available for Fungus Gnats:
-
Guardian and Lawn Guardian – beneficial nematodes good for deep containers.
-
Scanmask or Hortscan – Beneficial nematodes used in cold conditions (10 degrees
C/50 degrees F).

Insecticidal sprays are the lady bugs’ biggest enemy.

 Precautions / Release Information:

Do not release lady bugs to plants that have been recently sprayed with an insecticide. Spray plants down with water and allow most of water to fall off before releasing lady bugs.
Lady bugs can be stored up to two weeks in a refrigerator or cold area.
Lady bugs should only be released after the risk of frost has been established. It is also recommended that lady bugs are released in the evening or early morning, never in midday sun.
