The quiz questions are taken from:
The online learning pages focus on the important topics within worms, flies and lice and offer two approaches to learning: structured reading and question and answer.
We also welcome suggested questions for the quiz, (either reply on the ParaBoss News email if you are subscribed or use Contact Us, at the bottom of the web page).

1. How long do infective larvae of worms live?
2. Are there particular paddocks or areas where flystrike occurs more often?
3. How can the development of resistance of lice to treatments be slowed?
Let's not forget those who are still in drought.
Infective larvae are relatively tough and can withstand dry, cold and moderately hot conditions. All populations of living things vary in their life expectancy and worms are no different; some larvae will die within days, but some will live to around a year or more. Generally, over 90% of larvae will be dead within 6 months under cooler conditions and as little as 3 months when temperatures are ideal (about 25–30°C). Under extremely hot, dry conditions larvae will be desiccated and can die in a few days to weeks of these conditions, explaining why worms are rarely a problem in the arid zone.
In general, paddocks that are more exposed to wind, with less ground cover, timber and wet spots, will have less flystrike risk , making them more suitable for high risk mobs of sheep, such as marked lambs, daggy sheep and lambing ewes.
