There are tiny
superheroes that protect our tomato crop from destructive insect
pests. They are insects themselves, but rather than attacking
our precious crop of delicious organic tomatoes, they feed on
destructive insects.
In the photo on the
right you can see Dave Chapman, the owner and head grower at the farm,
inspecting the plants.
The little white card
hanging on the branch near his head contains the eggs of whiteflies (nasty
little bugs that can suck the life out of tomato plants). However,
these eggs have been parasitized by
Encarsia
Formosa (tiny little wasp-like insects that are our warriors in
our battle against the bad guys). The Encarsia fly around and
"sting" the whitefly eggs and lay their own inside. Pretty
soon, after devouring the larva inside, the young Encarsia pops out of
the whitefly egg and heads out to find non-parasitized eggs that
whiteflies lay on the underside of the leaves. And so the cycle
begins again until they run out of whitefly eggs.
We purchase these
Encarsia cards from companies that specialize in breeding and
producing methods of introducing these insects into the greenhouse
environment. Beneficial insects like Encarsia are very
expensive, but they are one of the most vital contributors to organic
growing because they act as a viable alternative to the chemical
pesticides that are all to commonly used in conventional greenhouse
growing. So, the next time you are enjoying a delicious Long
Wind Farm organic tomato, you can know that it is completely pure and
free of chemical contamination, and the Encarsia and all his little
friends are one of the reasons why.
