title: Associative learning in egglaying site selection by apple maggot flies.
abstract: Evidence is presented demonstrating that associative learning during oviposition in Crataegus or apple hosts can significantly influence the propensity of apple maggot flies to accept or reject these hosts in future encounters. The data suggest that within resource patches of a given host type there may be an enhancement of foraging efficiency.
