The susceptibility of worker honey bees, Apis mellifera L., as a function of age, to infestation by tracheal mites, Acarapis woodi Rennie, was investigated. Bees <24 h old were infested most frequently, and the frequency of infestation declined precipitously thereafter. Bees >4 days old were rarely infested in colonies during active brood rearing. Only 2 of 255 bees >8 days old, and 1 of 246 bees >16 days old, became infested. Most of the eggs found in bees>3 weeks old apparently were produced by the progeny of the original infestation.
