Application Number:	11/793,578
Patent Claims:	1. A mite composition comprising: a rearing population of the phytoseiid predatory mite species Amblyseius Swirskii, a factitious host population comprising at least one Astigmatid mite species, and optionally a carrier for individuals of said populations; wherein the Astigmatid mite is selected from the group consisting of: i) Carpoglyphidae, ii) Pyroglyphidae, and iii) Glyciophagidae. 2. The composition according to claim 1, the composition further comprising a food substance suitable for said factitious host population. 3. The composition according to claim 1, wherein the factitious host population is a rearing population. 4. The composition according to claim 1, wherein the number of individuals of the phytoseiid predatory mite species relative to the number of individuals of the factitious host is from about 100:1 to 1:20. 5. The composition according to claim 1, wherein the mite is a Carpoglyphidae and is a member of the genus Carpoglyphus. 6. The composition according to claim 5, wherein the mite is Carpoglyphus lactis. 7. The composition according to claim 5, wherein the mite is Pyroglyphidae and is a member of a genus selected from the group consisting of Dermatophagoides, Euroglyphus and Pyroglyphus. 8. The composition according to claim 7, wherein the mite is selected from the group consisting of Dermatophagoides farinae; Euroglyphus longior; Euroglyphus maynei; and Pyroglyphus africanus. 9. The composition according to claim 1, wherein the mite is a Glyciphagidae and is a member of a genus selected from the group consisting of Glycyphagus and Lepidoglyphus. 10. The composition according to claim 9, wherein the mite is selected from the group consisting of: Glyciphagus destructor, Glyciphagus domesticus; and Lepidoglyphus destructor. 11. A method for rearing the phytoseiid predatory mite species Amblyseius Swirskii, the method comprising: providing a composition according to claim 1, and allowing individuals of said phytoseiid predatory mite to prey on individuals of said factitious host population. 12. A method according to claim 11, wherein the composition is maintained at 18-35.degree. C. and/or 60-95% relative humidity. 13. A method according to claim 11, wherein said composition comprises a carrier and a suitable food substance and the factitious host population is maintained as a three-dimensional culture on the carrier. 14. A method for biological pest control in a crop, the method comprising providing a composition according to claim 1 to said crop. 15. A method according to claim 14, wherein the pest is selected from white flies, thrips, spider mites and tarsonemid mites. 16. The method according to claim 15, wherein the pest is white flies and is selected from the group consisting of Trialeurodes vaporariorum and Bemisia tabaci. 17. The method according to claim 15, wherein the pest is tarsonemid mites. 18. A method according to claim 14, wherein the composition is provided in a rearing system by placing said rearing system in the vicinity of a number of crop plants. 19. A method according to claim 14, wherein the crop is selected from the group consisting of peppers (Capsicum annuum), eggplants (Solarium melogena), Curcubits (Cucurbitaceae) (Cucumis sativa), melons (Cucumis melo), watermelons (Citrullus lanatus); strawberries (Fragaria.times.ananassa), raspberries (Rubus ideaus), roses, gerberas, chrysanthemums and Citrus species. 20. A method according to claim 14, wherein the composition is provided by applying an amount of said composition in the vicinity of a number of crop plants. 21. A method according to claim 20, wherein the amount is from 1-10 ml. 22. The method according to claim 14, wherein the pest is thrips and is selected from the group consisting of Thrips tabaci and Frankliniella spp. 23. The method according to claim 14, wherein the pest is spider mites. 24. A rearing system for rearing the phytoseiid predatory mite Amblyseius swirskii, which system comprises a container holding the composition according to claim 1. 25. A rearing system according to claim 24, wherein said container comprises an exit for at least one mobile life stage of the phytoseiid mite. 26. A rearing system according to claim 25, wherein said exit is suitable for providing a sustained release of said at least one mobile life stage.
