Amblyseius californicus - Release Instructions

Whats in the CaliLiv Tube?

Predator: Amblyseius californicus  –  The population is an active mite culture that includes all life stages.

Carrier: Bran or vermiculite – added so application is more even

Food: Prey mite –  included as a food source for the predatory mites to promote establishment.

How to release A. californicus:

  • For best results, release as soon as receiving shipment. Application should be during mild temperatures (early morning or late afternoon).
  • Gently rotate the tube to evenly mix the mites in the carrying material.
  • Sprinkle on top of plant canopy or place in bio boxes hung on the plant. Focus in hot spot areas.
  • Avoid chemical pesticides (organic or synthetic) before and after release.
  • Avoid top watering or washing plants

Can you store A. californicus?

We recommend releasing the predators immediately upon arrival.

If storage is necessary A. californicus can be stored for 1 day at room temperature in a dark, humid place (RH 60% or more). Avoid any contact with direct sunlight.

WARNING: Storing predatory mites accumulates Co2 overtime, always store in a well-ventilated place.

How to check the quality of the mites?

Due to colder temps during shipment predatory mites tends to huddle in the middle of the tube. If at first you don’t see any movement, allow the shipment to come to room temperature before conducting a quality check.

To check gently rotate the tube to evenly mix the mites. Pour a small sample on a white piece of paper and you’ll see fast moving mites crawling from the pile. You may need a 10x lens to see the mites.

How to promote establishment?

Temp and humidity: Californicus prefers a warm and humid environment (20°C - 30°C and over 70% RH). Californicus can survive lower humidity conditions in comparison to other predatory mites but still requires high humidity in order to breed.

Supplementary food: feeder mites, bug feed

How to spot A. californicus after releasing?

Californicus is tiny with an oblong shape and whitish pink in color. To spot californicus after releasing in the crop check the under leaves (near the veins and hairs) with a 10x lense to find its eggs. To measure effectiveness, mark the hot spots of spider mites and routinely monitor the population of the pest. Some good signs are reduced chlorotic spots and damaged webbings.
