title: Determination of poultry feed-through insecticide activity in an in vivo anticoccidial assay.
abstract: The ability of an in vivo anticoccidial assay to identify potential feed-through insecticides was demonstrated using first-instar Lucilia sericata on droppings from chicks fed medicated diets. Cyromazine, a commercially available feed-through insect growth regulator, ivermectin, diflubenzuron, fipronil, permethrin, and 2 experimental compounds were effective in varying degrees in killing L. sericata larvae. Eleven coccidiostats were effective against the protozoan parasites (Eimeria spp.) at commercially used levels, whereas they were ineffective against Lucilia larvae.
