During the summer of 2003, foliar symptoms including chlorotic spots and chlorotic mottling were observed on Hibiscus rosa-sinensis and H. syriacus plants in and around Las Cruces, NM. Detection of Hibiscus latent Fort Pierce virus (HLFPV) in numerous samples suggests that it may be widely distributed in New Mexico, as is the case in Florida and Thailand. Movement of ornamental plants could increase the geographic distribution of HLFPV. This represents the first report of HLFPV in the western United States. Accepted for publication 22 November 2004. Published 5 January 2005.

Species of Aphelinoidea Girault known to parasitize eggs of the beet leafhopper, Circulifer tenellus (Baker), in California were studied using both morphological and molecular characters. These include two introduced species (from Iran and Turkmenistan) as well as two indigenous species, A. zarehi n. sp. and A. roja n. sp. Earlier studies had identified the indigenous Aphelinoidea in California and other arid western states as A. plutella Girault, but we did not find putative A. plutella in our surveys of parasitoids of beet leafhopper eggs in California. We conclude that the earlier studies misidentified other indigenous species as A. plutella, and that at least some of these misidentifications were actually A. zarehi, one of the two new species described herein. A key to Aphelinoidea species known to parasitize beet leafhopper eggs in California is given. The key also includes A. plutella whose hosts are not known and for which we have no evidence as occurring in the western United States. DNA sequences support the separation of the four Aphelinoidea species reared from beet leafhopper eggs in California. Cross-mating tests also failed to show interbreeding between the taxa. Data are presented on developmental times of the two introduced species of Aphelinoidea.

Coherence of place often exists alongside irregularities in time in cycles, and chapter three turns to cycles linked by temporal markers. Ray Bradbury’s The Martian Chronicles (1950) follows a linear chronology and describes the exploration, conquest, and repopulation of Mars by humans. Conversely, Louise Erdrich’s Love Medicine (1984) jumps back and forth across time to narrate the lives of interconnected families in the western United States. Bradbury’s cycle invokes a confluence of historical forces—time as value-laden, work as a calling, and travel as necessitating standardized time—and contextualizes them in relation to anxieties about the space race. Erdrich’s cycle invokes broader, oppositional conceptions of time—as recursive and arbitrary and as causal and meaningful—to depict time as implicated in an entire system of measurement that made possible the destruction and exploitation of the Chippewa people. Both volumes understand the United States to be preoccupied with imperialist impulses. Even as they critique such projects, they also point to the tenacity with which individuals encounter these systems, and they do so by creating “interstitial temporalities,” which allow them to navigate time at the crossroads of language and culture.
