By October 6, this field ae been little injured, and such injury 
as had. occurred was caused by a few Anticarsia la rvae, the Heliothis 
caterpillars having slnost disappeared. _ while Trichozramma, with the 
help of Orius, had thus afforded a practically conpicte control of 
Heliothis in this 100-acre field, and although Trichogremma attacked 
the anticarsia eges, it is sup eee ess to explain the reason for control 
in this particular field, as other smaller and larger fields were 
largely or wholly destroyed by | both Tol otiae and Anticars ia larvae 
dice in association, or by anticarsia larvae alone. The most probable 
reason for this lack ae general control was in gruat flights of Anticarsia 
moths into the area, which deposited eggs in such abundance that the 
parasite did not mai ti ply fast enough to effect control.
