Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Prevent spread of the small hive beetleOne replicated trial in the USA tested the effect of using mite-killing strips in commercial honey bee Apis mellifera transport packages, to reduce the spread of small hive beetle. More than half the beetles escaped the packages and were not killed by the strip.

One replicated controlled before-and-after trial attempted to eradicate European buff-tailed bumblebees Bombus terrestris from trial sites in Japan by catching and killing foraging bees. The treatment led to an increase in numbers of two native bumblebee species, but did not eradicate B. terrestris.

This treatment increased the use of the boxes by native bees.

One replicated controlled trial in South Korea found that Indian meal moth Plodia interpunctella in commercial bumblebee colonies can be controlled with the insect pathogen Bacillus thuringiensis (Bt) Aizawai strain, at a strength of 1 g Bt/litre of water.

'No evidence' for an action means we have not yet found any studies that directly and quantitatively tested this action during our systematic journal and report searches. Therefore we have been unable to assess whether or not the action is effective or has any harmful impacts. Please get in touch if you know of such a study for this action.

One trial in Japan showed that externally mounted nets and zipped, netted entrances can keep commercial bumblebees inside greenhouses as long as they are regularly checked and maintained.
