AVANEX® unique endophyte technology may assist in reducing the number of birds on or near airfields. The alkaloids produced by the endophytes not only reduces the number of insects but can also reduce feeding of a number of bird species, including finches, gulls and wild Canada geese.

AVANEX® has been shown in trials to reduce insect numbers and as a result the area is less attractive to insect feeding birds. Figure 1 shows a significant reduction in insect numbers on the AVANEX® cultivars compared to grasses with wild type endophyte and grasses with no endophyte.

AVANEX® has also been shown to reduce bird populations through post digestion feedback. This is where birds that feed directly on the grass feel ill after feeding and learn to avoid the area.



At both Christchurch International Airport and Hamilton International Airport, AVANEX® grass showed reductions in bird presence.  For every bird spotted on AVANEX® plots, the exisiting vegatiaion had 19 times more birds present in Christchurch and 8 times more in Hamilton.

Canada geese and other bird species have also shown a significant avoidance of AVANEX® trial plots.

Selected AVANEX® plots also displayed decreased insect populations in comparison to both nil endophyte and wild type plots, highlighting the technology's diverse advantages.
