Some 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. Will worm larvae and eggs die during winter?
2. What are the two key signs that indicate that blowflies might be resistant to flystrike preventative chemicals on your property?
3. By which application methods can diazinon be applied as a lice treatment?
4. What causes wasting in goats?
Worm larvae can survive through the winter despite cold, frosts and snow due to the protection from the pasture and soil. In fact, they die faster during warm weather than cold weather.
Worm eggs vary in the required “maximum daily temperature” they require for hatching:
Brown stomach worm >8°C, Black scour worm: T. colubriformis >15°C, T. vitrinus >12°C, Barber’s pole worm >18°C. If it is too cold, they will die within days to weeks.
Eggs will also need at least 10–15 mm rainfall to hatch and develop.
Diazinon is an organophosphate (OP) that has caused serious illness in many users in the past. It is now only permitted for use in Richards-design submersible cage dips or as the spray-on product, Eureka Gold®
It is illegal to use diazinon in any other cage dip, plunge dips, shower dips, automatic jetting races, or hand jetting.
Note: only one company in Australia has a permit for cage-dip Diazinon use: Dipping Dynamics (owners and designers of the Richards-design cage dips). All other operators (and other application methods) should be using either the alternate OP, temephos, or a different chemical group altogether.
Scour worms can cause weight loss, but not all goats that are losing weight, weak and lethargic are suffering from worms, or they may be suffering from worms as well as another disease condition.
Other conditions that can cause weight loss:
