CREATING A NATIVE VEGETATION INSECTARIUM
Putting research into practice with an on-farm trial site
This project is supported by the PPWCMA, through funding
from the Australian Government’s National Landcare Programme

The multiple benefits of having native vegetation on your farm
• Shelterbelt• Habitat and food source for insects- (insectariums, beetle
banks, insect corridors)• Biodiversity values (consider offsets in planning applications)• Meet obligations in Environmental Assurance programs• Bush Food production- income diversification

Linking productive farming with natural resource management
• Working out what native vegetation provides food and habitat for beneficial insects and of this list of plants, what is indigenous vegetation to the property???
• = good biodiversity and productive outcomes
• Here is how I went about it for my trial site

IntraMaps: Local Councils with this functionality:http://mapsolutions.com.au/intramaps/intramaps-public.aspx
Contact your Shire council and ask what mapping capabilities they have to create a property map with an EVC plant list
EVC- Ecological Vegetation Class- benchmarking characteristics which describe plants and ecological functions of that EVC

CUSTOMISED SITE PLANTING GUIDE
Using the EVC list you have for the property, start to highlight plants you know are highly beneficial in an insectarium:
Sweet bursaria, wallaby grass, prickly tea-tree are the three HERO plants
What else is on your list that matches your planting space/layout and will provide nectar and pollen?
Shelterbelt- Upper and Middle story flowering plantsInsectary plants- HERO plants and similar ones found in your EVC. Make sure
there is diversity in your strata layers and include groundcovers.The customised list for Fieldberberry Farm is available at:
http://www.ppwcma.vic.gov.au/news/publications/NB: this is specific to this farm and is a GUIDE only.

Look for plants which you have seen featured in the research as appropriate insectarium species
Quite a few relevant EVC’s have bush foods, you just need to know what you are looking for
Plant a mix of EVC plants depending on the layout of your insectarium
The more plant diversity and layers, the better the habitat for diverse beneficial insects

Your insectarium layout can be any design you like• Grasses under vine or inter-row, end of row strainer posts• Surrounding a dam• Land class zoned unsuitable for production• Garden beds• Headlands, buffers and re-vegetated shelterbelts
It’s about insect corridors and connectivity to native vegetation

Is it working?• Spring in Victoria hasn’t been kind if you want to monitor insects!
10 sticky traps, one week (7 days) each month Sept-Jan3 pit fall traps in the main insectary planting, one week each month Sept-JanMonitoring for increases in abundance and diversity of beneficial insects over next 2 years, longer if my RLF project is re-funded!

Is it working?• Spring in Victoria hasn’t been kind if you want to monitor insects!
• However, 7 weeks after planting, some native plants were already flowering and spiders moving in to the insectary

Sent in for analysis. Interestingly, the newly planted insectary had much more diverse insects on the traps than the other areas being monitored. Main insect present is probably a hover fly (also called A flower fly) which is nectar feeding. It then lays eggs close to aphid infestations, when the larvae hatch, they feed on the aphids.

In summary• Find out what mapping capabilities your local council has available and map the
Ecological Vegetation Classes for your property
• Obtain the corresponding local EVC plant list
• Highlight any flowing plants that will provide nectar, pollen and/or shelter as habitat for predatory insects
• Check if you have any or all of the 3 HERO plants! Or similar species
• Decide on where you might plant insectary plants and where you can achieve multi-purpose (shelterbelt, planning offset, diversified income- cut flowers, bush foods etc)
• Monitor through sticky traps and/or observations
• Record the benefits- less pest problems, reduced pesticides, niche income etc
