The development of the asparagus miner (Ophiomyia simplex Loew; Diptera: Agromyzidae) in temperate zones: a degree-day model.

摘要: BACKGROUND: The asparagus miner is a putative vector of Fusarium spp., which have been implicated in globally declining production. Growers currently apply broad-spectrum insecticides for the miner, but lack management guidelines adequately controlling pest. Our aims were (1) to determine lower developmental threshold (2) develop and validate degree-day model describing its phenology, (3) create time budget help guide growers’ decisions. RESULTS: We found that was 12.1 ◦ C, phenology could be reliably predicted over course two-year study. Predictions from match well withpreviouslypublishedinformationonthebionomicsoftheasparagusminer,butfitbetterforsamplingdatacollectedfrom midwestern eastern United States than Kingdom. life cycle likely requires between 1500 2000 degree-days complete; longest requirement pupal stagen CONCLUSION: This study provides tools targeted by offering may used predict stages north-eastern States. c � 2013 Society Chemical Industry Supportinginformationmaybefoundintheonlineversionofthisarticle.
