Predatory Mite, Neoseiulus (Amblyseius) californicus

Product Options

Product Details

Predatory Mite, Neoseiulus californicus is a very effective in controlling different species of pests mites especially twospotted spider mite, Tetranychus urticae that cause a serious damage to many economically important crops grown both in the greenhouses and fields. Adults of predatory Mite, Neoseiulus californicus are clear-white in color whereas their larvae are translucent in color. Females of Neoseiulus californicus generally lay 40-45 oval shaped eggs among the colonies of pest mites. These eggs hatch into tiny larvae with six legs. These larvae develop through two developmental stages that termed as protonymphal and deutonymphal stages. Both these immature nymphal stages resemble to their parents. The males of predatory Mite, Neoseiulus californicus are smaller than the females.

+ Key factors for Predatory Mite, Neoseiulus californicus effectiveness
  • Neoseiulus californicus are natural predators of pest mites.
  • Both adult and nymphs of this predatory mite feed voraciously on all the stages of pest mites.
  • Females of this predatory mite feed on over 5 eggs of pest mites per day.
  • Neoseiulus californicus are very effective against pest mites and they can complete several generations when the temperature is above 16°C (60°F) and the relative humidity between 40-60%.
  • Neoseiulus californicus are commercially available and can be released in the pest mite infested crops.
+ How Neoseiulus californicus mites work in the greenhouses or fields
  • Neoseiulus californicus are known to feed voraciously on their hosts including spider mites.
  • After application in the greenhouses or fields, predatory Neoseiulus californicus mite starts munching on their host mites.
  • Each adult mite can consume 5 eggs of pest mites per day.
  • These mites also consume spider mites, one of the most important pests greenhouse and field crops.
  • While feeding, mites develop and reproduce rapidly.
  • Under favorable environmental conditions and if there is enough food around, these mite can recycle continuously (do not need to apply again and again) and help to keep the pest population under economic threshold level.
+ Predatory mite, Neoseiulus californicus feeds on following stages pest mites
  • Eggs of pest mites.
  • Nymphs and adults of pest mites.
+ How many predatory mites, Neoseiulus californicus should be release for the effective control of pest mites
  • 4-5 predatory mites/square feet (0.1 sq. meter) area bi-weekly, 2-3 times.
  • 5,000 to 25,000 predatory mites/acre, bi-weekly, 2-3 times.
+ When and how predatory mites, Neoseiulus californicus should be released
  • As a preventive control measure these mites should be released before the incidence of pest mites
  • As a curative measure these predatory mites should be released after you start noticing presence of pest mites on the plants.
  • Release Neoseiulus californicus mites when temperature is between 16-29°C (60-85°F) and the relative humidity is between 40-60%.
  • Release the adults of predatory mites opening vials and sprinkling them on plant leaves.
+ Why you need them
  • they can reduce the crop damage by feeding on crop pests responsible for the damage
  • they can munch on different stages of their hosts including eggs
  • they are able to actively search for their hosts and feed on them
  • they can reproduce and continue their life cycle on the foliage after first application
  • they are commercially available and easy to apply in the greenhouses or fields
+ Why predatory mites are safer than traditional pesticides
  • they do not damage plants
  • can be used and applied around children and pets
  • do not cause any harm to the personnel involved in their production and application
  • food products are safe to handle and eat when they are treated with mites
  • they do not harm humans, animals and pollute the environment
