Three out of seven -- dead in October. Central Louisiana. Had Apistan in for six weeks following the crop in July; took it out around the first of September, weighed the colonies, and gave the light ones heavy sugar syrup in top feeders. All hives had robber screens on them, were in good tight condition, and the feeders didn't leak. Nevertheless, robbing started as soon as we fed them. The fights were stand-offs for a week or so, but eventually three of the colonies were overwhelmed, including the most productive hive in the yard. The surviving colonies are now honey-blocked (or were until we pulled some frames to give to the new replacement colonies). The victims were, I think, destroyed simply by the raiders, without the help of mites. The feeding was probably the cause, I reckon, although I have done fall-feeding for years without significant raiding. Not next fall, though. Incidentally, we have had another non-winter, are well into spring, and are already seven inches behind our average rainfall at this point. We finished last year ten inches behind for the whole year. Despite the dry weather, the bees averaged 100 pounds per colony, including two trapped swarms. Walter Weller
