Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Eradicate existing populations of invasive non-native speciesOne replicated trial in Louisiana, USA, demonstrated that colonies of invasive Africanized honey bees Apis mellifera can be killed by providing insecticide (acephate)-laced syrup for 30 minutes. 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.

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.

Another study of the same system found evidence that corridors were used by some bird species more than clearcuts between patches, although corridors near cut forest were not used more than those near uncut stands.
