Have you measured any resistance development by the mites by constant and frequent OA usage?

@beequipnz6442 10 месяцев назад

There have been no reports of any signs of varroa resistance to OA from any of our many beekeeper clients in NZ. We still get the same excellent mite drop with OAE strips in our hives now, as we did 4 years ago. Some scientists say that they don’t believe it is possible for the mites to get resistant to OA.

Does the OA build up in the wax over time or make the wax unusable as a secondary product (lip balms, candles, etc.) in any way?

@beequipnz6442 Год назад

We can find no evidence of OA building up in the beeswax. All honey has OA in it already so it is highly unlikely.

How much OA is left in the strips when removed and how do they handle water absorption from the air?

@beequipnz6442 Год назад

Hello Daniel, good questions. A key point to remember is that honeybees maintain the brood nest at 54 to 60% humidity and the temperature stays close to 34°C. The bees are very fussy about this. If the strips are placed in the brood nest correctly, then they are not exposed to excess moisture in the atmosphere. It is not a problem. If the strip is not in the brood nest and is exposed to atmospheric conditions, it can absorb water. We haven’t measured exactly how much OA is left in the strip at 7 or 8 weeks but what we do know is that most of the useable OA has been dispensed in the hive at that point.

Can use OA in summer? because all know mites is brood

@beequipnz6442 Год назад

The Oxalic strips work great in summer. They can be used any time of the year, if it is warm enough for the bees to have brood frames.

@neildavidson8097 Год назад

are the strips dry or wet when you put them in and do you notice a difference between the two

@beequipnz6442 Год назад

The strips are wet when soaked properly. But they shouldn’t be so wet that they dribble when picked up from the storage bin or rack. Each strip holds 23 grams of solution so there would be something wrong if it appeared dry. If the varroa mite levels are kept under control, bee mortality is very low when the wet strips are added.
