A good rain for Colorado Beetle. And
really rather amazing to think of their species in terms of their having
developed a resistance to so wide a range of pesticides.
Resistance to DDT was an early victory in their battle for
dominance over Potato and Eggplant crops. A Colorado Beetle has two
other enemies. One is a Beetle that eats Colorado Beetle eggs and
Colorado Beetle hatchlings. The other is a white fungus that also does
damage to Termite, White Fly, Thrips and Aphids, to name just a few.
This white fungus has no resistance to fungicide.
The white fungus is called Beauveria Bassiana.
Which is classic, because no one this side of a science museum can pronounce
or remember Beauveria Bassiana. The disease in insects Beauveria
Bassiana causes is called White Muscardine Disease. If you see a Grasshopper
corpse on a hot day and it looks frosted that's White Muscardine.
Which sounds like a wine, but which helps my memory not in the least.
I prefer "The White Pox of Insect." Which is distinct from "The White
Pox of Plants." The Beetle that feeds on the eggs and hatchlings of
Colorado Beetle, has shiny Eggplant black wing case, orange front parts and
black beady eyes. It's name is Lebia Grandis, which might be easier to
remember. It's a quick moving Beetle and it's about the size of a
Bomber Beetle, which is that brown Beetle that thinks beating it's head
against the electric light is an Olympic sport.
