| 摘要： 本類水果生產期間之蟲害以東方果實蠅(Bactrocera dosalis (Hendel))及太平洋臀紋粉介殼蟲(Planococcus minor (Maskell))防除工作最為重要。因此尋找低毒性藥劑或非農藥防治資材是為可行之道。 本計畫擬針對現有東方果實蠅及粉介殼蟲田間防除技術，如誘引劑、食物誘餌、化學藥劑、套袋及田間衛生管理等，以嚴謹密度監測技術，搭配地理資訊系統(GIS)，田間作物相與生長季節，研擬ㄧ套番石榴區域性綜合蟲害管理規範。並建立粉介殼蟲周年性密度消長資訊，累積長期資料及其它小型害蟲資料，釐定此類害蟲在番石榴上之防治時機。Two pests of the oriental fruit fly (Bactrocera dosalis Hendel) and mealbug (Planococcus minor Maskell) seriously subjected to damage the production of guava fruits. It is urgently necessary to develop control fruit fly and mealbug. The project intends to address the existing field control techniques, such as attractants, food baits, pesticides, bagging and field sanitation, strictly detect pest densities with geographic information system (GIS), and include crop growing season. The object is to develop sets of area-wide integrated pest management for guava farms to decrease the cost of production and increase the value of product. |
