Sixteen species of helminths (five cestodes, eight nematodes, and three trematodes) were found during examination of 215 moose from Alberta. Different helminth faunas occurred in moose from the major population in the west and north, and from isolated populations in central (Elk Island National Park) and southeastern (Cypress Hills Provincial Park) Alberta; only Moniezia sp., Taenia hydatigena, and Nematodirella longispiculata were found in all three populations. Thysanosoma actinioides, Protostrongylus macrotis, Setaria labiatopapillosa, Fascioloides magna, and Zygocotyle lunata were found in only one of the three populations; their presence was most likely due to cohabitation by moose and other infected vertebrates. The presence of wolves probably accounted for the high prevalence of Echinococcus granulosus, T. hydatigena, and Taenia krabbei in the west and north, while coyotes were of local importance in maintenance of E. granulosus and T. hydatigena in the park populations. Wehrdikmansia cervipedis was not found in park populations probably because of absence or scarcity of the intermediate host. Moniezia expansa, P. macrotis, S. labiatopapillosa, and Z. lunata are reported for the first time from moose in North America.

The European, or Essex skipper, Thymelicus (= Adopaea) lineola (Ochs.), was accidentally introduced into North America at London, Ontario, sometime before 1910 (Saunders, 1916). The history of its subsequent spread through southern Ontario and adjoining parts of Michigan and Ohio was reviewed by Pengelly (1961), who received the first report of extensive damage to hay and pasture crops by this insect in Ontario from the Markdale area of Grey County in 1956. A survey in 1958 (Pengelly, 1961) showed that the skipper “appeared to be present throughout the southern part of the province except for the Bruce peninsula and possibly the Windsor area. The northeasterly boundary appeared to he along a line from Midland, south around the west side of Lake Simcoe, east to Lindsay and south to Whitby.” The present author collected T. lineola larvae from the Belleville area for the first time in 1959.

ABSTRACT The distribution of the callitrichids inhabiting the Tapajós-Xingu interfluvium is still poorly understood, probably because of the limited number of studies in this remote region. Mico emiliae is a callitrichid endemic to Brazil, occurring between the Jamanxim and Teles Pires rivers, and Serra do Cachimbo in the west and Iriri River in the east, in the states of Pará and Mato Grosso. However, its current distribution is still uncertain. After ca. 430-km surveys in Serra do Pardo National Park, we successfully confirmed the occurrence of this species for the first time approximately 180 km east of its previously known eastern limit in Pará. Our records expand the distribution of M. emiliae to the left bank of the Xingu River, increasing the known extent of its occurrence by 83%.

Ninety-eight wolves and 75 coyotes from the forested regions of Alberta were examined for helminths. Fourteen species (2 trematodes, 8 cestodes, and 4 nematodes) were recovered from wolves, with a mean of 2.6 and a maximum of 6 species per wolf; 18 species (3 trematodes, 8 cestodes, and 7 nematodes) were recovered from coyotes, with a mean of 2.0 and a maximum of 6 species per coyote. Helminths common in wolves were Taenia hydatigena (79% of the wolves infected), Echinococcus granulosus (72%), Taenia krabbei (52%), Toxascaris leonina (14%), and Taenia pisiformis (13%), Toxascaris leonina (52%), Alaria americana (33%), Taenia pisiformis (31%), Uncinaria stenocephala (16%), and Filaroides osleri (15%) were common in coyotes. Metorchis conjunctus, Taenia omissa, and T. taeniaeformis appear to be new records for wolves and M. conjunctus, Taenia twitchelli, Diphyllobothrium sp., and Capillaria aerophila appear to be new for coyotes.High indexes of similarity (and comparable indexes of diversity) suggest that the helminth faunas of wolves in various regions of North America are basically similar. This similarity is probably due to similar food habits of wolves from various regions.The helminth fauna of coyotes appears to vary extensively in diversity and in species between the regions studied. The fauna from the coyotes from the area around Lac la Biche, Alberta, differed markedly from that of the other samples, with a generally richer fauna of different species, more equitably distributed. The helminths, particularly the cestodes, from coyotes from Minnesota and from Banff National Park were as similar to those of wolves as they were to those of coyotes from other areas. These features may be due to the food habits of the host coyotes.

Larvae of the nematode Salvelinema walkeri (Ekbaum, 1935) and metacercariae of the trematode Crepidostomum metoecus (Braun, 1900) are recorded for the first time from the amphipod Ramellogammarus vancouverensis Bousfield, 1979 (Amphipoda: Gammaridae).The infected amphipods were collected from De Mamiel Creek, southwestern Vancouver Island, British Columbia. Brief descriptions are given of both parasites, which as adults live in salmonid fishes. This report provides the first record of an intermediate host for S. walkeri, a swim-bladder parasite of salmonids of the Pacific region of North America, and of an intermediate host of a Crepidostomum species in the Pacific region of Canada.

ArgumentAt the beginning of the twentieth century, the Russian mathematician Andrey A. Markov extended the laws of the calculus of probability to trials that were dependent on each other, purely theoretically. In two articles from 1913, which are presented here in English translation, he applied his theory for the first time to empirical material, namely text. After a presentation of Markov's methods, results, and possible inspirations, the introduction investigates the dissemination of his ideas to Western Europe and North America in detail. The experimental application of his method to various types of text finally determines its scope.

The west coast of North America record of the shallow-marine stromboid gastropod genusRimellaAgassiz, 1841 is restudied for the first time in 90 years. This genus comprises a small group of Paleogene gastropods characterized by having an ornamented fusiform shell, a posterior canal ascending the spire, and simple (non-flared) outer lip.Rimella, whose familial ranking has been inconsistent, is placed here in family Rostellariidae Gabb, 1868, subfamily Rimellinae Stewart, 1927.EctinochilusCossmann, 1889;MacilentosClark and Palmer, 1923;VaderosClark and Palmer, 1923; andCowlitziaClark and Palmer, 1923 are recognized here as junior synonyms ofRimella. Four species are recognized from the west coast of North America: early to middle EoceneRimella macilentaWhite, 1889; early EoceneRimella oregonensisTurner, 1938; middle to late EoceneRimella supraplicata(Gabb, 1864) new combination, of whichRostellaria canaliferGabb, 1864,Cowlitizia washingtonensisClark and Palmer, 1923, andCowlitzia problematicaHanna, 1927 are recognized here as junior synonyms; and late EoceneRimella elongataWeaver, 1912.Rimellawas a warm-water gastropod whose earliest known record is of early Paleocene (Danian) age in Pakistan. Other than the west coast of North America,Rimellais found in Eocene strata in western Europe, Turkey, Egypt, Pakistan, southeastern United States, Panama, Peru, and, to a lesser degree, in Trinidad, Columbia, Java, and New Zealand. Global cooling near the end of the Eocene greatly diminished the genus. Its youngest known occurrences are of early Oligocene age in Germany, Italy, England, and Peru.

Drosophila suzukii (Diptera, Drosophilidae) is an exotic species, endemic to Asia and currently a pest to small and stone fruits in several countries of North America and Europe. It was detected in 2013 for the first time in South America, in the south of Brazil. Unlike most drosophilids, this species deserves special attention, because the females are capable of oviposit inside healthy fruits, rendering their sale and export prohibited. Despite the confirmed existence of this species in different states of Brazil, this insect is yet been to be given the pest status. Nevertheless, the mere presence of this species is enough to cause concern to producers of small fruits and to justify further investigation for it’s control, especially chemical control for a possible change in status. Therefore, the goal of this work was to evaluate, in laboratory, mortality of D. suzukii adults and ovicidal effect when exposed to different insecticides registered for species of the Tephritidae and Agromyzidae families in different cultures. The insecticides deltamethrin, dimethoate, spinosad, fenitrothion, phosmet, malathion, methidathion, and zeta-cypermethrin resulted in mortality to 100 % of the subjects three days after the treatment (DAT). Regarding the effects over eggs, it was  established that the insecticides fenitrothion, malathion, and methidathion deemed 100 % of the eggs not viable, followed by phosmet and diflubenzuron, which also caused elevated reduction in the eclosion of larvae two DAT.
