Mite composition comprising a predatory mite and immobilized prey contacted with a fungus reducing agent and methods and uses related to the use of said composition

摘要

The present invention in general relates to the field of biological crop protection by use of predatory mites. More particularly the present invention relates to a mite composition comprising a predatory mite and a prey. Such a mite composition is suitable for rearing the predatory mite and/or for crop protection using the predatory mite. The prey in the composition comprises individuals of at least one Astigmatid mite species, wherein at least a fraction of the Astigmatid individuals is immobilized. The composition is characterized in that immobilized Astigmatid individuals are contacted with a fungus reducing agent.

主权项

1. Mite composition comprising:
a population of individuals of a predatory mite species, preferably a predatory mite species selected from Mesostigmatid mite species or Prostigmatid mite species; a food source for the predatory individuals comprising individuals of at least one Astigmatid mite species, wherein at least a fraction of the Astigmatid individuals is immobilized; optionally a food substance suitable for Astigmatid individuals; and optionally a carrier for the individuals of the mite species; wherein immobilized Astigmatid individuals, and optionally the optional food source for Astigmatid individuals, are contacted with a fungus reducing agent comprising a fungus reducing mite population selected from a mycophagous mite species or an antifungal exudates producing mite species, said fungus reducing mite population preferably being selected from Astigmatid species.
