General description

Tiny wasps which lay their eggs into moth eggs. The wasp larva develops into a fully formed wasp inside the moth egg. So, a wasp emerges from a moth egg instead of a caterpillar.

Supplied in capsules each yielding 1,000+ wasps.

Place capsules in a grid fashion through the crops when moths are laying eggs.

Will vary greatly depending on the situation and aim of release - inoculative or inundative.

60 to 180 capsules per hectare depending on pest pressure.
