BioSwirski – The Product

  • Amblyseius swirskii is packed in a 1 liter container with 50 000 predators. Mites are mixed with bran, along with their food, the prey mite, Carpoglyphus lactis. The prey mites do not survive on the plant and are harmless to the crop.
  • The material can be sprinkled from the container over the crop or applied by specially designed distribution boxes that are hung on the plant. The former application method is good for horizontal crops whereas the latter is more effective in vertical crops.
  • If necessary, BioSwirski can be stored for 24 hours at a temperature of 10-15°C from the time of arrival until release, but it should never be frozen, nor left exposed to direct sunlight.
  • BioSwirski is compatible with selective conventional chemicals (according to the list of compatible chemicals provided by BioBee)


  • Prior to release, the container should be rotated gently while in a horizontal position to allow proper mixing of the predatory mites in the bran carrier.
  • Application of BioSwirski should be carried out either early in the morning or late in the afternoon, under relatively mild temperatures.
  • During application, the containers should be taken from shipment package one by one and the predators should be released immediately.
  • In crops where Amblyseius swirskii can feed on pollen, such as sweet pepper, BioSwirski can be introduced preventively before the appearance of the target pests, upon presence of the first flowers. The release rate depends upon the nature of the crop, the ecosystem (e.g. open field or greenhouse) and the rate of pest infestation. Temperatures of 21-27°C and high humidity (above 60%) will enhance predator activity and ensure its success.
  • Where pollen is not available for the predators, Amblyseius swirskii should be introduced upon the first appearance of the target pests.
