An important principle of
Integrated Pest Management (IPM)
is to adjust the level of control to suit the level of
infestation. Low mite levels need no action;
intermediate levels may require some moderate
intervention; high mite levels require more urgent and
effective action.
In context, light control means using
varroacides or biotechnical
methods that have a relatively low
efficacy and therefore have a fairly limited effect on
the mite population. Effective control means using
varroacides or biotechnical methods that are very
effective and greatly reduce the mite population.
A Guide To
When Control Is Required
Slowing mite
population growth
Employ
methods that slow down the growth of the Varroa
population in your colonies, such as drone brood
removal and the use of open mesh floors. These will have
a less dramatic effect than other controls, but will
delay the point when the infestation reaches a damaging
level and so allow you to treat a little later or use a
less efficacious varroacide.
