Natural parasitism of leafminer Liriomyza trifolii (Burgess) in jalapeno pepper in northern Sinaloa, Mexico.

摘要

Parasitoids of L. trifolii on Capsicum annuum were studied in 3 municipalities (Guasave, Ahome and El Fuerte) in Sinaloa, Mexico, from September 2008 to April 2009. Twenty-nine samples were collected weekly during the autumn-winter season. A total of 142 parasitoid specimens were obtained from the 3 plots. The specimens belonged to the following taxa: Opius dissitus (17.0%), Opius sp. (30.9%), Closterocerus cinctipennis (34.5%), Neochrysocharis sp. (17.0%), and a species under Figitidae (0.7%). O. dissitus is a new record for Mexico. The Neochrysocharis sp. was dominant in all plots during the first month, but its incidence decreased to nearly zero after the second week of January. The other 3 species were present throughout crop development, increasing in abundance until December.Digital Object Identifier http://dx.doi.org/10.3958/059.035.0409
