Is the alternating mowing of orchard alleys an option to promote # owerbugs on pears?

In a trial conducted in three pear orchards under
organic and two under integrated pest management
during the 2016 season, no e1 ects
of alternating versus complete mowing of alleys
every 14 to 21 days on the population density
of ; owerbugs (Anthocoris spp.) was observed.
These and other bene< cial organisms were
already present at su= cient numbers to act as
antagonists of pear leaf suckers (Cacopsylla pyri)
during the development of second-generation
nymphs after ; owering. Therefore the use of
non-harmful insecticides during the 2016 season
is likely to have been more important than the
alternating mowing of alleys. Only long-term
studies can show whether this is a general trend
in Northern Germany.
