06¥M1410.Ellis.note There is evidence for a positive correlation between the level of Varroa desructor Anderson and Trueman infestation in a colony and the attrac- tiveness of the brood to the mites (Büchler, 1989, 1990). This correlation may be associated with actual increases in colony mite levels as suggested by the work of Fuchs (1992) who was able to con- firm a significant correlation between brood attrac- tiveness and colony mite increase and a positive correlation between brood attractiveness and fer- tility of the mites. Differences in brood attraction may be associated with race differences in bees (Büchler, 1989). The present study was designed to test if brood attraction also can be affected by the chemotherapeutic history of the brood. The agents tested in this experiment were Fumidil B® (fumagillin) and Terramycin® (oxytetracycline), two antibiotics widely used in apiculture. The methods are described schematically in Fig- ure 1. Four genetically distinct lines of honey bees were identified (one alleen oer line). Two of the four line were headed by free-mated queens (each from a different queen producer) while the other two were single-drone instrumentally inseminated queens. Each line was housed in a single story Langstroth colony. Each genetic line colony was treated with 2 strips of Apistan acaricide (fluvali- nate) for 2–4 weeks prior to the start of the experi- ment and fed sugar syrup until colonies had similar reserves of food. Four different (medicated) colonies were set up to receive test antibiotics. Each medicated colony was requeened with one of four free-mated, sister queens. These colonies were isolated from other colonies to minimie V. destructor drift and treated with Apistan for 24 days immediately prior to receiv- ing the antibiotics. Fumidil B was delivered in 1:1 sugar syrup and Terramycin was delivered in pow- dered sugar, both at mixture rates recommended by manufacturers. Each of the medicated colonies received one of the following treatment regimens: (1
