INSECTS THRIVE ON GM 'PEST-KILLING' CROPS

Jim Webster

my broad statement was preceded by the word "most"

try google using "beneficial insects" "pesticide application" "effects on"

Any integrated pest management user knows that pesticides and
beneficial insects are not very compatible. Of course, some pesticides
are less toxic to some particular beneficial insects. But it is not
difficult to understand that beneficial insects get the triple wammy
of pesticide effect, lack of available insects to prey or to parasite and
the little prey the find is poisoned.
