Description

Mite Predator


A general predator for many different mite pests. Survives well when pest densities are low.



Neoseiulus(= Amblyseius) fallacis is an excellent general predator mite for control of many different types of mites in warm, moderately humid environments. Particularly recommended for spider mites on roses and vegetable crops in greenhouses, N. fallacis can also help suppress cyclamen mites in strawberry fields and broad mite in greenhouses. N. fallacis has been found to be more effective than N. californicus in northern climates on Mint, Hops and Strawberries. It can also be effective in orchards against the European red mite and the two-spotted spider mite, as it tolerates higher temperatures and lower humidities than P. persimilis.

Appearance:


Adults are pear-shaped and slightly smaller than the European red mite adult. They are white until they feed after which they take on the coloration of their prey (usually red or brown). The eggs are pear shaped, almost transparent, but slightly larger than the round European red mite eggs. The nymphs are also transparent and difficult to see without a microscope. Of the five N. fallacis life stages, only the 1st nymphal stage is six legged. All other post-egg stages have eight legs. If you are unsure about the specific pest insect(s) you are dealing with, take a look at our Quick Pest Reference Guide.

Life Cycle:


Mated adult females may overwinter in plant crevices or other protected areas if prey is available in the fall. Females enter diapause in response to shortened day lengths (<14 hours). They emerge as early as bloom, but in reduced numbers due to heavy winter mortality. N. fallacis increases in number rapidly and adults become numerous by July or August. They live about 20 days and lay an average of 40-60 eggs. Eggs are laid along the ribs of the undersides of leaves. Warmer or cooler conditions accelerate or slow down reproduction/feeding respectively, so take that into account when planning a Biological Control program.

Relative Effectiveness:


Because N. fallacis is a voracious consumer of mites and because its population increases quickly in relation to its prey, it can overtake an expanding pest population. It develops into the adult stage in about one third the time required by other mite predators. Additionally, they will feed on pollen in the presence of a reduced prey population. N. fallacis will actively control mite populations at temperatures above 64°F and prefers moderate to warm conditions with a relative humidity of 50% or higher. For this reason, N. fallacis mite predators work extremely well to control mites in greenhouses. Suggested for tomatoes, roses and other vegetable crops.

Release Rates:


Some crops, including tomatoes & other highly resinous crops, require higher release rates.


Comments:


Spring releases are typical, but fall releases should be considered depending on the pest insect population being controlled. They are effective in a preventive capacity. Please call us for recommendations if you plan on applying predatory mites to a large area or multiple sites.
