Six Inch Petri dishes and How to use them.
|Stack of petri dishes with cocoons inside a manual defrost fridge.|
|A thermometer is an important tool to make sure the temperature
is right for keeping cocoons under hibernating conditions.
In late Jan temperature is lowered to between 2-4C or 35-39F
|Always keep a container of water inside the fridge.
This is an easy way to make sure that humidity is above 60%.
|Label each petri dish.|
|In a manual defrost fridge, there is a freezer compartment
that will require defrosting each year.
|In spring, the occasional male will emerge even
though temperatures are low.
|For spring emergence, cocoons can be placed into Starter
cottages or Emergence Cottages. These can be temporarily
stored in the fridge, until weather conditions are reasonable.
|Store cocoons inside Petri dishes that may contain parasitic wasps.
Place on kitchen counter in spring. If any bees emerge
they can be released. Parasitic wasps can be destroyed by freezing .
