FOWLES Wines in Avenel has partnered with University of New England (UNE) for a ground-breaking study of insect-eating micro-bats as vineyard pest control, which could ultimately save Australia’s wine industry $50 million per annum, according to Fowles.
The joint study is investigating whether the micro-bats are consuming pests in the vineyard at the same rate as in cotton farms, with the potential to increase the use of natural resources in the broader wine industry.
“Every day, the bats can consume 30 to 100 per cent of their body mass," Fowles Wines owner Matt Fowles said.
"A colony of 100 bats, weighing 10 grams each, could remove up to one kilo of insects every night.
“There are 16 species of insect-eating bats in Victoria, including four endangered species, but we don’t know how many of them are living and foraging in the vineyards.
"What we do know is that where the bats populate and can echolocate is where the vines and fruit thrive most.”
Dr Heidi Kolkert and Dr Zenon Czenze from UNE have installed sound recording devices in the Fowles vineyards to better understand the different bat species living there, their insect feeding habits, and the role they play to maintain biodiversity in the local ecosystem.
"In the first year of the 'Bats and Wine' initiative our preliminary results suggest that bats play a vital role in controlling agricultural pests within NSW vineyard ecosystems,” Dr Czenze said.
“This current project with Fowles represents a leap forward — the most comprehensive study yet — aimed at unravelling bat diversity and their ecosystem contributions within vineyards.”
Along with the ‘Bats and Wine’ initiative, the researchers also completed a fauna survey for a more holistic understanding of wildlife at Fowles Wine and the greater region.
In another initiative aimed at harnessing the power of nature, Fowles has also partnered with Euroa Arboretum to establish insectariums – which double as ‘seed orchards’ – comprising diverse native flowering shrubs and trees across their vineyards and farmland.
“The insectariums are planted to attract diverse predator and pollinator insect life, adding diversity of native plants in and around the vines and ensuring a natural balance,” Mr Fowles said.
“The insectariums will also allow the Euroa Arboretum to collect seed to ensure they can regenerate native plant life on the property, or further afield, which is vital in regional Victoria where bushfires are a large threat to many plant species.
“In addition, the insectariums provide shelter and nesting space for birds and provide stepping stones for wildlife movement.
“We are literally inviting insects into our vineyard, which is the very different to traditional practices for growing vines.
"We are encouraging the natural occurrences that mother nature provides.”
Fowles has also welcomed beehives to its vineyards where the bees can work their magic on the vines and cover crops, helping ensure the vines can thrive and produce the grapes that enhance the flavour in every glass.
