Jonathan, you are not the only orchard to experience severe apple maggot
damage this past season. I don't believe any consensus has been arrived at
as to when or how. In some cases it has been felt to have been early
damage. In others it has mainly impacted later varieties such as Cortland,
Red Del, etc. In others use of pyrethroids has been implicated or heavy
rain wash-off.

The timing to kill Apple Maggot is when the adult flies are present in the
orchard flying around and feeding but prior to oviposition. There is
currently no pupacide on the market and if there was we would be applying
it with a ground sprayer to the orchard floor, not an airblast rig to the
tree canopy.

I would think that because apple maggot over winter on the ground that
reduction of amount applied per acre in theory would result in a less
than proper amount of active material applied to control the pest.
The small to large house would not be as important as the fact that each
was on a one acre lot. Just my opinion and experience.
