Some activity, 50 mg of ETB
caused formation of
larval–pupal
intermediates after the
fourth instar
Some activity, induction of
precocious
metamorphosis seems to
correlate with
prolongation of the larval
developmental period in
the third instar
Precocenes Short-term activity seems to
be effective and long-term
activity shows that
damage to CA is
irreversible
Activity can be inhibited by
stimultaneous application
of methoprene
