The braconid Diachasmimorpha longicaudata rainforest (locally known as “Las Yungas forest”) (Ashmead) is a fly native to the (Cabrera 1976). Climate is defined as temperate- Indo-Pacific region, which has been widely dis- hot humid with a summer rainy season (Dec seminated into America via Hawaii (Ovruski et through Mar), winter dry season, and annual al. 2000). It was used in augmentative release rainfall varies from 259 to 1,947 mm.
