Abstract

Twenty-one species of fleas, seven of which are considered true ground squirrel fleas, were collected by various means from Spermophilus richardsonii (Sabine), S. tridecemlineatus (Mitchell), and S. franklinii (Sabine) in Manitoba. Opisocrostis tuberculatus tuberculatus (Baker), O. labis (Jordan and Rothschild), Neopsylla inopina Rothschild, and Rhadinopsylla fraterna (Baker) are ground squirrel fleas reported from Manitoba for the first time. These, in addition to Oropsylla rupestris (Jordan) and Thrassis bacchi bacchi (Rothschild), were restricted to the southwestern region of the province, but Opisocrostis bruneri (Baker) was collected throughout the range of the ground squirrels, irrespective of location. Fourteen species collected were considered accidental on ground squirrels, one of which, Tamiophila grandis (Rothschild) (an eastern chipmunk parasite), was recorded for the first time in the province.

Résumé

Au Manitoba, on a prélevé par diverses techniques sur Spermophilus richardsonii (Sabine), S. tridecemlineatus (Mitchell) et S. franklinii (Sabine) vingt-et-une espèces de puces, dont sept sont considérées comme de véritables puces des spermophiles. Les puces Opisocrostis tuberculatus tuberculatus (Baker), O. labis (Jordan et Rothschild), Neopsylla inopina Rothschild et Rhadinopsylla fraterna (Baker) sont rapportées pour la première fois au Manitoba. Ces dernières, ainsi que Oropsylla rupestris (Jordan) et Thrassis bacchi bacchi (Rothschild) ne sont présentes que dans la partie sud-ouest de la province, alors que Opisocrostis bruneri (Baker) se retrouve dans toute l’aire de distribution des spermophiles. Parmi les espèces de puces trouvées, 14 sont considérées comme accidentelles, notamment Tamiophila grandis (Rothschild) (un parasite du tamias) qui est mentionné pour la première fois dans cette province.
