The manual can be used in conjunction with the FlyBoss website (www.flyboss.org.au). There are a wide range of management and breeding options currently in use. Different combinations of the available tools will suit producers in different enterprises and regions with varying risk of flystrike incidence. The preferred combination of tools and strategies needs to fit current risks, markets and other farm operations but it is also important that producers continually review their plan to ensure that it can be effective and fits in well with the future demands as well. The manual includes coverage of management options, such as the strategic use of chemicals, shearing and crutching, breech modification, scouring and worm control, and breeding for breech strike resistance. licesense The liceSense manual is an update of the manual issued by AWI at the start of 2010. With the spread of resistance to some backliners and the removal of Diazinon as a sheep dipping agent, AWI is once again making available this handy guide on managing sheep lice. The manual can be used in conjunction with AWI’s liceBoss website (www.wool.com/liceboss). This liceSense guide is a refresher for lice management principles, which are: 1. Find lice early 2. Plan your flock protection 3. Know the costs and gains 4. Plan a successful treatment. Sheep lice are an insidious and costly pest so it is important to find them early. If you already have the 2010 version, you won’t need the new version.
