title: Oviposition stimulants in the coccoid cuticular waxes ofAphytis yanonensis De Bach & Rosen.
abstract: Aphytis yanonensis De Bach & Rosen, a parasitic wasp of the arrowhead scale,Unaspis yanonensis (Kuwana), was introduced to Japan to controlU. yanonensis. A. yanonensis recognizes a host insect by antennal contact and deposits eggs on the insect body underneath the scale. Ovipositional behavior is induced by perceiving the cuticular wax of the host insect,U. yanonensis, and other coccoids. Chemical composition of the cuticular wax was analyzed and oviposition stimulants were isolated following a bioassay usingA. yanonensis.
