Accounts of how long bumblebees live, do vary between species and studies.For example, Bombus terricola workers were observed to be 13.2 days on average – around 2 weeks. But in other studies, workers were observed to live for up to 41.3 days – about 6 weeks. It is believed that workers engaged in nest duties live longer than bumblebee workers whose main duty is foraging. These bumblebees are of course more prone to predator attack, and are also exposed to varying weather conditions. It is not unusual to find a bedraggled looking bumblebee needing to rest and revive itself having been caught in a shower.
RELEASE INSTRUCTIONS: Place the hives preferably evenly distributed along the south-side of the main path in the greenhouse in order to have the maximum shade from the crop in summer. The best position is on a horizontal platform (avoid inclination else sugar solution may leak). Before opening the flight hole, allow the colonies to calm down minimum half hour after placing on final position. Whenever possible, open flight hole when vents are closed to prevent loss of workers.
Natupol performs best at ambient temperatures of 10-30°C/50-86°F.It may be necessary to provide extra shade (e.g. with styrofoam). The sugar solution that is provided with the hive is generally sufficient for the entire life of the colony. Secure the hive so that ants cannot enter it, f.e with a barrier of grease or insect glue. Also avoid contact between plants and hive, since this can also be a way for ants to reach the hive. If pollination is required during a longer period, regularly place new hives in the greenhouse.
