release against the 3rd generation will continue within 7d after the second phase of
the previous stage, whereas in non-overlapping ones, it will began 25-28d after the
peak of the second generation relying on traps’ catches. This coincides to while one
week remains to peak of the third generation. The two additional releases will
continue every other week. Release areas of apple orchards covered by Tricocards
have been shown in Fig. 6.3.
