- Executive summary:
Cyhalothrin has been evaluated for its ability to induce micronuc1eated polychromatic erythrocytes in the bone marrow of C57BL/6JfCD-l/Alpk mice. Cyhalothrin was given as a single oral dose to groups of five male mice at dose levels of 13.5 or 21.6mg/kg and to groups of five female mice at dose levels of 15.5 or 24.8mg/kg; these being 50% and 80% of the median lethal dose as determined over a four day period. Bone marrow samples were taken for analysis 24, 48 and 72 hours after dosing.
An examination of the incidence of micronucleated polychromatic erythrocytes showed a negative response for cyhalothrin at both of the dose levels tested. The positive control substance, cyclophosphamide dosed at 65mg/kg, gave significantly increased frequencies of micronucleatect polychromatic erythrocytes at the 24 hour sampling time, thus demonstrating the sensitivity of the test system to a known clastagen.
It is therefore concluded that cyhalothrin is not clastagenic in this assay.
