Neoseiulus (Amblyseius) fallacis is a native North America predatory mite, used to supress pest mites such as two-spotted spider mites, spruce spider mites, European red mites, cyclamen (or strawberry) mites and broad mites in fruit, ornamental and market garden crops.
Adults are pear-shaped, 0.5 mm long, with long legs. They can vary in colour from cream to orange-beige. The immature stages are generally a semi-transparent cream colour. The eggs are oval and 0.33 mm in diameter (double the size of a two-spotted spider mite egg).
Neoseiulus fallacis has excellent dispersal abilities and can withstand the cold and heat (active between 9 °C and 32 °C). This predatory mite can survive when pest populations drop to low levels. Fallacis is easily establishes itself throughout outside crops.
|Preventive in greenhouses||2||per m2||weekly or bi-weekly||as needed|
|Curative light in greenhouses||5||per m2||weekly or bi-weekly||as needed|
|Spider mites in field||2||per m2||once||year|
|Broad mites in field||5||per m2||once||year|
Leaf morphology (smooth surface, presence of hair, etc.) influence the effectiveness of predatory mites.
