Key messages

One replicated controlled trial showed that excluding ants from solitary nests of the endemic Australian bee Exonuera nigrescens increased production of offspring.

 

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. In a replicated controlled trial in Cobboboonee State Forest, Victoria, Australia, 50 single female nests of the endemic allodapine bee Exonuera nigrescens were protected from ants using two plastic cups and the sticky barrier Tanglefoot (Zammit et al. 2008). Fifty control nests were not protected. The nests, made in old flowering stems of the grass tree Xanthorrhoea, were set out in groups of four, one protected and one unprotected. Protected nests were more productive, with an average of 3.6 young per adult female, compared to 1.6 young per adult female in control nests.
