Systemic Effect of Dieldrin on the ‘Body Louse’ of Poultry

Abstract

SYSTEMIC administration of parasiticides has been the subject of sporadic research for several decades but has only recently gained prominence in veterinary thought. Successful results have been reported with Cimex lecticularis ^1,2, C. hemipterns ², Aedes aegypti ¹, Ornithodorus moubata ¹, Boophilus microplus ³, Hypoderma lineatum ^4,5, H. bovis ¹ and Haemotobia irritans ^6,7. All the foregoing insects suck blood, or come in close contact with the host's tissues or fluids. This communication describes experiments showing a powerful systemic effect against the biting louse of poultry, Eomenacanthus straminous, which has no such close contact with the host's tissues.
