AWI provides Australian woolgrowers with tools for best practice lice control to minimise woolgrowers' costs and chemical use, and improve clip quality. In addition, AWI funds research into new lice diagnostic methods and environmentally-friendly lousicides.
Lice are estimated to cost the Australian sheep industry $125m per year, although this figure was mostly likely higher in the decade to 2010.
For many woolgrowers, lice control relies on a best practice approach to chemical choice and application to remove an infestation, and good flock management to prevent reinfestation. Woolgrowers at risk of reinfestation may elect to control lice each year.
The management of lice on-farm is underway against a backdrop of:
AWI is addressing these threats and attempting to lower the cost of louse control for woolgrowers in two ways:
AWI's LiceSense guide (PDF 1.0Mb) is a woolgrowers' guide to managing sheep lice in response to spreading lice infestations in all Australian states.
The LiceSense guide is a 'refresher' for lice management principles, which are:
The LiceSense guide does not cover all the details of lice management. Woolgrowers can also attend extra training days and seek further advice when planning lice protection and treatment for their sheep.
AWI invests in several projects addressing resistance development by lice and scrutiny of lice treatments, to provide a steady stream of new tools for lice management.
A fungal biological control that colonises and kills lice needs a new commercial partner to further develop a commercially viable product.
AWI is working with a commercial partner on research into a new class of treatments that blocks the ecdysone hormone in both sheep lice and blowflies.
A long term goal for AWI is to develop an on-farm test to detect lice that cannot be seen in wool partings on rubbing sheep. Accurate test results could avoid the need for unnecessary lice treatments off-shears, saving woolgrowers money, and reducing wool residues and the pressure for resistance development.
AWI is considering new research for a test after past investments failed to make a breakthrough.
ParaBoss is a suite of three products – LiceBoss, WormBoss and FlyBoss – developed to help sheep producers in the management of lice, worms and blowflies.
The LiceBoss, WormBoss and FlyBoss websites are sources of detailed management information and regional programs that will assist in managing the major parasite risks for sheep. The websites have been developed by expert panels of parasitologists and veterinarians from across Australia.
ParaBoss provides access to the three websites at www.paraboss.com.au.
Subscribe to ParaBoss News, the twice monthly free email newsletter with state outlooks on the current state of sheep parasites as well as feature articles and the quick quiz to test your knowledge of sheep parasites.

LiceBoss - for more information and to use a decision support tool to manage lice, visit LiceBoss which was developed by AWI and aligned with FlyBoss and WormBoss by the Sheep CRCto deliver integrated decision support tools for woolgrowers managing lice, flies and worms. LiceBoss offers specific information about all aspects of lice and their control and also useful decision tools on whether lice might be present, what products to use on different types of sheep and their residues and costs.Lice management advice - contact the primary industries/agriculture or related organisation in your state.
