Abstract: The present invention relates to a biological control composition comprising at least arthropod biological control agents and astigmatid mite eggs. The invention also relates to the use of astigmatid mite eggs as a nutrient source for arthropod biological control agents. The invention also relates to a biological control composition comprising at least one population of arthropod biological control agents, a nutrient source comprising astigmatid mite eggs, and optionally, a support and/or dissemination substrate. Finally, the present invention further relates to a method for rearing arthropods from astigmatid mite eggs as a nutrient source.

Abstract: The invention relates to a novel aqueous suspension preparation comprising a water-suspended microparticulate calcite mineral with a particle diameter ?35 ?m, plant extract, and a surfactant that can shift the zeta potential of the water-suspended microparticulate calcite mineral into the negative range, and the use of this aqueous suspension preparation as a foliar fertilizer. The invention also relates to a foliar fertilizer comprising this aqueous suspension preparation.

Abstract: The present invention concerns a sprayable aqueous composition intended for feeding biological control agents comprising eggs from at least one arthropod species and one or more thickeners and/or gelling agents, and a method for preparing such a composition, the use of same as a nutrient source for biological control agents and for improving the effectiveness of biological control methods, and biological control methods.
