Spider Mite Biological Control:

The glasshouse spider mite or two spotted spider mite Tetranychus urticaeis is a common pest of protected crops with adult females laying up to 120 eggs in 3 weeks. Motile stages suck the contents out of plant cells and produce characteristic leaf damage of white or silvery speckled patches.

Almost all protected crops and soft fruit are vulnerable to infestation.

Phytoline p (Phytoseiulus persimilis)

Phytoseiulus adult feeding on two spotted spider mite <br/> (Photo: Holt Studios) Type: Small orange/ red predatory mite, has been used for over 45 years.

How it works: Predator actively hunts and attacks all stages of mites.

Species controlled: Tetranychus spp. (two spotted spider mite).

When to use:

Can be used on protected edible and ornamental crops as well as outdoor soft fruit. Cannot establish in the absence of spider mites (Tetranychus spp.) and performs best in warm, relatively humid conditions but may fail in hot, dry conditions.

Rates of use:

5 to 10 mites per m2. Some low humidity crops or indoor atria may require twice this rate.

Anderline aa (Amblyseius andersoni)

Type: Predatory mite.

How it works:

Predatory mite preys on eggs, larval and adult stages of a range of mite species including glasshouse spider mite, citrus mite, fruit tree spider mite, rust mite and thrips. Able to survive on pollen, fungal spores and plant sap in absence of prey and hence can be applied preventatively. Survives high and low temperature but low humidity limits development.

Species controlled: Glasshouse spider mite and other spider mite species.

When to use: Preventatively. The slow release sachets allow release overa 6 week period from a breeding colony.

Rates of use: One twin sachet per 1 m2
