Fecha de publicación: -- Fuente: WIPO "tomato" The invention is directed to yeast-microencapsulated larvicide compositions for controlling larval pest species in their immature stages before they emerge as adults. The larvicide composition can be used as a cost-effective and efficient method for controlling multiple larval pest species (e.g., Musca domestica, Aedes albopictus, Culicoides sonorensis). The larvicide compositions are made by encapsulating an active isoxazoline larvicide ingredient (e.g., fluralaner) with a yeast cell wall through microencapsulation. In one aspect, an encapsulation solution of active larvicide ingredient, yeast, and water is agitated, and a yeast-microencapsulated fluralaner pellet is separated from the encapsulation solution and is freeze-dried to obtain a dry, shelf-stable powdered larvicide composition that can be reconstituted with water and applied to aquatic or terrestrial larval development substrates in the same manner as other wettable powders or granulated insecticides.
