californicus is a very commonly used predatory mite. It is often
referred to as the “Cali mite”. It will feed on two-spot spider
mites, carmine mites, and eriophyid mites. Alternatively it will feed on
pollen and other arthropods, keeping itself alive when there is a shortage
of prey to feed on. I like to think of is a more the “slow release” mite,
working at a consistent steady pace.
mite is active at temperatures from 55 F to 105 F. Another interesting
trait about the Cali mite is that if they run out of any food source, they
will cannibalize their young to stay alive. After they run out of food
and begin to starve, if a food source is then found, the females will then
“fatten” up and start to lay eggs again. When persimilis starve down,
they can not recover.
bodies are pear-shaped and ivory in color.
californicus mite feeds primarily on spider mites. Also they will
feed on broad mites, cyclamen mites, and pollen.
N. californicus does better in warm, humid conditions, with a minimum
RH of 50% and temperatures up to 38°C. Like all other arthropods, the time
to complete its life cycle varies with temperature. N. californicus can complete its life cycle in 1 to 2 weeks. An adult female, on average,
can lay 3 eggs per day.
