Gypcheck - The Gypsy Moth Nucleopolyhedrosis Virus Product
gypsy moth nucleopolyhedrosis virus
(NPV) is naturally ocurring and is the most common
cause of the decline of outbreak gypsy moth populations.
Since the late 1950's sceintists have been developing
the use of this virus as a biological pesticide.
In 1978, the product, "Gypchek" was registered by
the US Environmental Progection Agency
(EPA). A similar product,
"Disparvirus", was developed in Canada.
Gypchek is produced by growing caterpillars
on artificial diet, infecting individuals,
harvesting cadavers, and purifying the product.
This method, referred to as "in vivo" production,
is labor intensive and this is why application
of Gypchek is relatively expensive. Research is
currently underway which may some day allow for
"in-vitro" (cell culture) production. This could
result in substantially lower production costs.
