Parasitoids comprise a speciose insect group, displaying a wide array of life history strategies. In the Pacific Northwest of the United States, the tephritid fruit fliesRhagoletis tabellaria(Fitch) andRhagoletis indifferensCurran infest red osier dogwood,Cornus sericeaL. (Cornaceae), and bitter cherry,Prunus emarginata(Douglas ex Hooker) Eaton (Rosaceae), respectively. The flies are parasitized by different braconid wasps at different life stages;Utetes tabellariae(Fischer) oviposits intoR.tabellariaeggs, whereasDiachasma muliebre(Muesebeck) oviposits intoR. indifferenslarvae feeding in cherries. BecauseRhagoletisonly have one major generation a year and the wasps attack temporally distinct fly life stages, we predicted that eclosion times ofU.tabellariaeshould more closely follow that of its host than the larval-attackingD.muliebre. As predicted,U.tabellariaeeclosed on average 6.0–12.5 d later thanR.tabellaria, whereasD.muliebreeclosed on average 32.1 d afterR.indifferens. Unexpectedly, however, longer chill duration differentially affected the systems; longer overwinters minimally influenced eclosion times ofR.tabellariaandU.tabellariae but caused earlier eclosion of bothR.indifferensandD.muliebre. Results imply that in temperate regions, diapause timing in braconid wasps evolves in response to both host life stage attacked and fly eclosion characteristics, possibly reflecting differential effects of winter on host plant fruiting phenology. Differences in phenological sensitivity of the lower host plant trophic level to variation in environmental conditions may have cascading effects, sequentially and differentially affecting eclosion times in higher frugivore (fly) and parasitoid (wasp) trophic levels.
