(Also known as: Neoseiulus californicus; Typhlodromus marinus; Typhlodromus mungeri; Neoseiulus californicus; Spider mite preditory mite) |
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement. These hazard alerts do not take account of usage patterns or exposure, thus do not represent risk.

|
An active predatory mite that feeds predominately on Tetranychidae mites at all development stages |
|
Tetranychidae pests including the red spider mite, two-spotted spider mite, tarsonemid mites and carmine mite |
|
Protected crops grown at elevated temperatures and some field crops where temperatures are high |

Adults are small and reddish-brown in colour. Eggs are oval and around 0.15mm in diameter. Mites pierce their prey and suck out to eat the thrips internal organs. |

Often supplied as units of 2,000 or more mites mixed with an inert carrier material such as vermiculite in 100 cm³ vials. Apply at a rate of 1-6 mites per m2 per week. |
|
The predatory mites are collected from leaves in a production system that rears the mites on plants such as legumes |
|
According to environmental studies, insect farming can produce as little as 1–5 kg CO₂e per kg of insect biomass, depending on species, feed type, and energy sources used. |
