Although
we have not tested the effect of hydrogen cyanide on Euplectrus the
high concentration of cyanide released by ‘Florona’’ stargrass might
mediate the attraction of Euplectrus to the fall armyworm strains
fed on this grass. The results for the timing of oviposition seems
to indicate that Euplectrus female might be mildly repelled by
HIPV, since no clear preference was shown, when both strains were
feeding on this grass
