RESISTANCE TO DELTAMETHRIN IN BOOPHILUS MICROPLUS (CANESTRINI) (ACARINA: IXODIDAE) IN NEW CALEDONIA

Abstract

A strain (S) of Boophilus microplus collected from the east coast of New Caledonia was compared with a strain (R) from the west coast for resistance to deltamethrin. The R strain was significantly more resistant than strain S with a 5.7 fold resistance factor determined at the LD50 using the larval packet technique. This is the first report of synthetic pyrethroid resistance in B. microplus in New Caledonia. Copyright © 1992, Wiley Blackwell. All rights reserved
