> One thing I thought might be useful to share with others is a collection
of “signs” that can give one shortcuts to identifying hive issues.
Hi Tony, the signs that you mentioned are all good--sorry that this
discussion got sidetracked by the OTC issue!
Here are some more, off the top of my head, in no particular order:
1. Inadequate flight at entrance compared to others.
2. Lack of returning pollen foragers; lack of pollen around brood.
3. Dead/dying/crawling bees in front of entrance.
4. Bees with deformed wings.
5. Mite counts by some means--after nutrition, this is most important.
6. Irregular brood pattern.
7. Dead/dying larvae/pupae.
8. Poor adult bee:brood ratio--first sign of impending colony collapse
(due to excessive loss of workers)
9. Sealed:open brood ratio of less than 50% suggests high larval mortality.
10. Amount of jelly around day-old larvae--this is best indicator of colony
nutritional state.
11. Colony not gaining weight consistent with other colonies in the apiary.
