The present invention in general relates to the field of biological crop protection by use of phytoseiid predatory mites. More particularly the present invention relates to a system for releasing a phytoseiid predatory mite in a crop and novel uses of host mites in such phytoseiid predatory mite releasing system. The phytoseiid predatory mite releasing system according to the invention and the uses according to the invention are characterised by the selection a host mite species having an intrinsic growth rate (r) of &#x3c;0.28.

predatory mite releasing system and method for production

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 onemite species, wherein at least a fraction of theindividuals is immobilized. The composition is characterized in that immobilizedindividuals are contacted with a fungus reducing agent.

Phytoseiid predatory mite releasing system and method for production

The present invention relates to a novel mite composition comprising a population of a phytoseiid predatory mite species and a factitious host population comprising a species selected from the Glycyphagidae, which may be employed for rearing said phytoseiid predatory mite species or for releasing the phytoseiid predatory mite species in a crop. According to further aspects the invention relates to a method for rearing a phytoseiid predatory mite species, to the use of the mite composition and to a method for biological pest control in a crop, which employ the mite composition.
