Fallacis Neoseiulus
Description
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.
Neoseiulus fallacis can be used with the predatory mite Phytoseiulus persimilis and the predatory beetle Stethorus punctillum in a management strategy against spider mites.

Life cycle
- Neoseiulus fallacis has a life cycle of 7 to 9 days at 21 °C, or 3 days at 32 °C.
- Adults live from 14 to 62 days.
- N. Fallacis is active from 9 °C to 32 °C and needs humidity levels over 50%.
- Females lay 1-5 eggs per day, for a total of 26 to 60 eggs in their lifetime.
- A female will consume 2 to 16 spider mites per day
- Outside, adult females enter diapause when the days get shorter (less than 14 hours of light).
- Neoseiulus fallacis will not enter into diapause in greenhouses when temperatures are kept over 18 °C.
