Any information on Round Headed Apple Tree borers (Saperda candida) and
nematodes?? Where does one get such nematodes?

Peach growers combat several insects that harm their crop, usually
using chemical pesticides to do so. Agricultural Research Service
(ARS) scientists in the Southeastern Fruit and Tree Nut Research
Laboratory in Byron, Ga., are seeking environmentally friendly
alternatives.
The scientists knew from lab studies that another peach pest, the
lesser peachtree borer, is also highly susceptible to S. carpocapsae.
But the researchers also realized that controlling the lesser peachtree
borer would be more difficult because they attack trees
aboveground--where the nematodes dry out and are less effective.
To deal with this problem, the researchers applied S. carpocapsae
nematodes to tree wounds and then covered the wounds with
moisture-holding bandages. In the first trial, 100 percent lesser
peachtree borer mortality was attained in five days.
