Diamondback moth, Plutella xylostella
Around the world, diamondback moth (DBM) is a major threat to those
much loved vegetables, brassicas (cabbages, cauliflowers and other
related greens). It is attacked by the fungus, Zoopthora radicans,
but too late in the season to help growers.
In a novel approach,
the insects themselves will be used to spread the fungal spores
to other DBM earlier in the season than the natural outbreaks would
occur. Male moths, attracted to inoculation stations by pheromones
(sex attractants), will pick up the fungal spores and then spread
them through the DBM population.
has advantages over chemical insecticides, both in terms of environmental
and economic sustainability and avoidance of resistance problems.
This is particularly important because of the advantages that 'clean
and green' produce confers upon our export and domestic markets.
