Seasonal History

This bark-beetle is locally distributed over the forested areas of Quebec and Ontario, extending westward into Manitoba; in the United States, it has been recorded from Wisconsin and Michigan.The insect has been found breeding in fallen white pine and jack pine, and, within recent years, has also been recorded from red pine.

History Of

The pine engraver, Ips pini (Say), is one of the most common bark beetles found in pine and spruce in eastern Canada. Clemens (1916) studied its biology in New York State, and more recently, Reid (1955) reported the seasonal development of this beetle in Alberta. Prebble (1933) discussed the larval development at Fredericton, N.B., and I have listed the associates of this species found in red and white pine logging slash in western Quebec (Thomas, 1955). Leach, Orr and Christensen (1934) and Orr (1935) discussed the association of this bark beetle wit11 blue-staining fungi in red pine logs in Minnesota. Most of the observations reported in this paper concern the life history of I. pini in jack pine at Black Sturgeon Lake in northwestern Ontario from 1952 to 1960. Supplementary observations were also made on the seasonal development of this insect in red pine in southern Ontario in 1956 and 1957, and in white pine at Laniel, Quebec, in 1951.

AbstractMessa populifoliella (Townsend), long known in the United States but new in Canada, is univoltine and overwinters as a prepupa in the soil beneath the host tree. In New Brunswick the larvae mine the leaves of Populus eugenei Simon-Louis creating blotch mines. The various stages of the sawfly are described and pictured and six parasite species are named.

An American Language is a political history of the Spanish language in the United States. The nation has always been multilingual and the Spanish language in particular has remained as an important political issue into the present. After the U.S.-Mexican War, the Spanish language became a language of politics as Spanish speakers in the U.S. Southwest used it to build territorial and state governments. In the twentieth century, Spanish became a political language where speakers and those opposed to its use clashed over what Spanish's presence in the United States meant. This book recovers this story by using evidence that includes Spanish language newspapers, letters, state and territorial session laws, and federal archives to profile the struggle and resilience of Spanish speakers who advocated for their language rights as U.S. citizens. Comparing Spanish as a language of politics and as a political language across the Southwest and noncontiguous territories provides an opportunity to measure shifts in allegiance to the nation and exposes differing forms of nationalism. Language concessions and continued use of Spanish is a measure of power. Official language recognition by federal or state officials validates Spanish speakers' claims to US citizenship. The long history of policies relating to language in the United States provides a way to measure how U.S. visions of itself have shifted due to continuous migration from Latin America. Spanish-speaking U.S. citizens are crucial arbiters of Spanish language politics and their successes have broader implications on national policy and our understanding of Americans.

Background: Although considered a tropical disease, strongyloidiasis may be encountered in non-endemic regions, primarily amongst immigrants and travelers from endemic areas.  Chronic strongyloides infection may be under-detected owing to its non-specific cutaneous presentation and the low sensitivity of commonly used screening tools. Methods: 18 consecutive patients with serologic evidence of strongyloides infestation who presented to a single urban, academic dermatology clinic between September 2013 and October 2016 were retrospectively included.  Patient age, sex, country of origin, strongyloides serology titer, absolute eosinophil count, presenting cutaneous manifestations, and patient reported subjective outcome of pruritus after treatment were obtained via chart review.  Results: Of the 18 patients, all had non-specific pruritic dermatoses, 36% had documented eosinophila and none were originally from the United States. A majority reported subjective improvement in their symptoms after treatment. Conclusion:  Strongyloides infection and serologic testing should be considered in patients living in non-endemic regions presenting with pruritic dermatoses and with a history of exposure to an endemic area.Key Points:Chronic strongyloidiasis can be encountered in non-endemic areas and clinical manifestations are variableEosinophilia was not a reliable indicator of chronic infection in this case series Dermatologists should consider serologic testing for strongyloidiasis in patients with a history of exposure and unexplained pruritus
