The obliquebanded leafroller, Choristoneura rosaceana (Harris), is one of the major arthropod pests of apple in the United States. In 1999 and 2000, a survey of the obliquebanded leafroller parasitoid complex in commercially managed apple orchards in Michigan's two largest fruit production regions was conducted to determine the species present and their importance to obliquebanded leafroller po...

1. When an invasive species first colonizes an area, there is an interval before any host-specific natural enemies arrive at the new location. Population densities of newly invading species are low, and the spatial and temporal interactions between spreading invasive species and specific natural enemies that follow are poorly understood. 2. We measured infection rates of two introduced host-spe...

The New World and largely Neotropical genus Peckia Robineau-Desvoidy, 1830 is revised with a key to all species. Peckia is considered a senior synonym of Guanoxipha Lehrer, 2012, n. syn. and of Sarcodexia Townsend, 1892, n. syn., the first one under Squamatodes Curran and the latter maintained as a valid subgenus, which here is redefined giving the new generic combinations Peckia (Sarcodexia) l...
