Die berüchtigte Afrikanisierten oder so genannte "Killer bees" gegenüber den Vereinigten Staaten sind die Migration über Mittelamerika.

The notorious Africanized or so called "killer bees" are migrating toward the United States via Central America. "This bee, while not as aggressive as some reports would suggest, is a source of concern as its presence in the United States could impose economic hardships on our bee- keepers, " says Erickson. "This is because, with it, will come a new bee disease, caused by a Varroa mite, and undesirable behavior problems associated with honey production and crop polUnation." If the mongrels do reach the United States, perhaps the natural interbreed- ing with new lines of gentler bees could reduce their threat to the beekeeping industry, says Erickson. And advances in the use of AI in closed bee populations could enable establishment of African-gene-free germplasm reservoirs for restocking apiaries that may be despoiled. If research shows the closed population approach to bee breeding produces high quahty queens, Erickson says the methodology would be such that any bee breeder could conduct a selection program. Moreover, their improved bees may be kept for many years to come. leffers DAVID, NOT DICK I happened to see your June 1982 issue of CRANBERRIES and wish to inform you that your offices have made an error. On page 8 there is a photo of a small boy looking out of the window of a Model T dump truck and you have him named as Dick Johnson. It is not Dick Johnson, but rather myself, l^avid Johnson.

Solon and Carl Johnson were brothers, Solon having passed away a few years ago. In any event, I thought I would inform your magazine of the error. If the error is corrected in any future editions of your magazine, 14 I would appreciate a copy o
