The alfalfa leafcutting bee, Megachile rotundata (Fab.), is a domesticated pollinator important for alfalfa seed production in western Canada. Populations of M. rotundata are highly susceptible to chalkbrood, a disease caused by the fungus Ascosphaera aggregata Skou. The disease has caused high mortalities in M. rotundata populations in the northwestern United States since 1972. It was found in Manitoba in 1982, Alberta in 1983, and Saskatchewan in 1984 (Richards 1985). In subsequent surveys, A. aggregata has been detected only sporadically and at low levels of infection in Saskatchewan M. rotundata populations (Goerzen 1991). A previously reported observation of A. aggregata in the native leafcutting bee M. relativa Cresson (Goerzen et al. 1990) indicated that the disease is present in native leafcutting bee species which commonly immigrate into alfalfa leafcutting bee nest material.

Do So

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.
