The apple maggot fly, Rhagoletis pomonella (Walsh 1867) (Diptera: Tephritidae), is an economically important pest of apples (Malus domesica Borkh.) (Rosaceae) throughout much of the United States. The fly is endemic to the eastern U.S., where its primary host plants are several species of native hawthorns (Crataegus spp.) (Rosaceae). About 150 years ago the fly shifted to apples in the Northeast. More recently, the fly has been introduced to the western U.S. outside of its native range. In the state of Colorado, R. pomonella attacks the fruits of a number of different native and introduced hawthorn species, but is generally absent from apples. While orchards in apple growing regions are closely monitored, backyard and non-commercial apples often go largely unexamined. Here, we report results from a survey of non-commercial apples at 16 locations in eight counties across Colorado. We document the discovery of one R. pomonella infestation of apple at low density in Boulder, Colorado in close proximity to highly attacked, introduced downy hawthorn (C. mollis Scheele) in a residential neighborhood. Our finding represents the first confirmed infestation of apple in the state in 25 years. We discuss the implication of our findings for apple maggot management.

A new braconid, Macrocentrus delhiensis sp. nov., is described and illustrated from New Delhi, India. Specimens were collected on weeds near a mango orchard. Including this new species, seven species of Macrocentrus Curtis 1833 are known from India.

The genus Geovelia Zimmermann 1984, previously known from Nepal and Myanmar (Burma), is recorded for the first time from Yunnan, China. A new species G. hispida sp. nov. is described. Digital photographs, a diagnosis, and line illustrations of abdominal segment VIII and the male paramere are provided to assist in the identification of this new species. A distribution map for all species in the genus is provided, along with a key to all the known species.

An annotated list of Nevada Trichoptera and related literature with information on unpublished new records is provided. A total of 137 Trichoptera species are now known from Nevada. Four genera, without confirmed species, and 76 species are newly reported. One species, Ecclisomyia simulata Banks 1920, is resurrected from synonymy.

A new species of the genus Megaselia, M. apifurtiva sp. nov., is described and illustrated. The species was collected from nest of Apis laboriosa Smith 1871 (Hymenoptera: Apidae).
