On August 22, 1933, while the members of the Montreal staff were inspecting a nursery in Montreal, P. Q., a small number of sawfly larvae was observed feeding on the mugho pine trees. These were submitted to Ottawa and were identified as the larvae of Diprion simile Htg. This was the second record of the appearance of this species in Canada; the first being a record from Oakville, Ont., in 1931. This insect had previously been studied in the Northeastern United States by Britton and Zappe (1917) and Middleton (1923).

Pine sawfly larvae, Neodiprion spp., are the most common defoliating insects of pine trees, Pinus spp., in Florida. Sawfly infestations can cause growth loss and mortality, especially when followed by secondary attack by bark and wood-boring beetles (Coleoptera: Buprestidae, Cerambycidae, Scolytidae,). Trees of all ages are susceptible to sawfly defoliation (Barnard and Dixon 1983, Coppel and Benjamin 1965). This document is EENY-317 (originally published as DPI Entomology Circular No. 258), one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

In this article, I explore how the social contract of schooling and the three functions of schooling (Noguera 2003)—to sort, to socialize, and to control— impact and constrain the freedom and agency of a group of young Black and Latinx men in one suburban school district that was experiencing sociodemographic shifts in the Northeastern United States. I use qualitative data to frame how the young men experience schooling, and I show how the local community context facilitates the institutionalization of discriminatory sorting processes and racially prejudiced norms. I also show how the young men are excessively controlled and monitored via zero tolerance disciplinary practices, which effectively constrains their humanity and capacity to freely exist in their school and which inadvertently strengthens the connective tissue between schools and prisons.
