Bionomics of Rhagoletis pomonella1 in Crataegus2

The bionomics of the chiroptera

Bionomics of Culiseta particeps in southern California.

The distribution of Culiseta particeps (Adams) in California appears to be restricted in Califor-nia to the Pacific coastal areas and scattered patches in the Riverside and San Bernardino counties (Darsie and Ward 1981). However, Iit-tle information exists on the adult ecology and abundance of this species. Larvae have been found in marshes, margins of streams, residual pools in stream beds and...

Bionomics of the face fly, Musca autumnalis.

The face fly was introduced from the Palearctic region and spread across North America in 20 years after World War II. Adults feed on cattle and horses, and larvae develop in fresh cattle dung. Little genetic differentiation appears between European and North American populations and among regions within North America. After an autumnally initiated diapause, overwintered flies emerge in spring ...

Analysis of Body Measurements and Wing Shape to Discriminate Rhagoletis pomonella and Rhagoletis zephyria (Diptera: Tephritidae) in Washington State

Rhagoletis pomonella (Walsh) (Diptera: Tephritidae) is a quarantine pest of apple (Malus sp.) inWashington state that is almost identical morphologically to Rhagoletis zephyria Snow, a nonpest of apple. Historically, the longer ovipositor inR. pomonella has been used to separate it from R. zephyria, despite overlap in ovipositor lengths. Here, the objectives were to determinewhether use of mult...

Potential geographical distribution of Rhagoletis pomonella (Diptera: Tephritidae) in China

Apple maggot fly, Rhagoletis pomonella (Walsh) is a major pest causing considerable economic losses of fruits in North America. During the development of international trade, apple maggot fly has become a threat to Chinese agriculture. In this study, CLIMEX and ArcGIS were used to predict the potential geographical distribution of apple maggot fly in China. The parameters used in CLIMEX for app...
