Apple Orchard

Atractotomus mali (Meyer-Dür, 1843) (Hemiptera: Miridae) is a zoophytophagous insect associated with orchards in Europe and North America. In Canada, it has previously been reported in apple (Malus domestica Borkh) orchards in several provinces, but mainly in Nova Scotia, where it induced more damage on fruit than predatory effects. During the summer of 2014, we collected 33 specimens in an apple orchard in Magog (QC, Canada), using a tapping method. This study constitutes the first record of A. mali in Quebec.

AbstractSphaerularia bombi Dufour is an internal nematode parasite of bumble bee queens in North America and Europe. Infection functionally castrates the bee. Here we document the prevalence and intensity of S. bombi infections in seven species of Bombus and three species of Psithyrus on Cape Breton Island, Nova Scotia, Canada. We found dramatic variation in prevalences among Bombus spp., and some evidence that prevalence increased as the nesting season progressed. Also, we report S. bombi in the bumble bee nest parasite Psithyrus insularis (Smith), the first record for the genus in North America.

The introduced European weed scentless chamomile, Matricaria perforata Mérat (Asteraceae), is a target for biological control in Canada (Peschken and Sawchyn 1993). As part of this project, the fauna on scentless chamomile in Canada has been investigated (Woo et al. 1991). In 1990, a total of 25 adult Apion weevils were dissected out of 115 flower heads collected at two locations in Antigonish County, Nova Scotia, on 23 August and 4 September. These were identified by D.E. Bright as Apion hookeri Kirby, 1808 (Coleoptera: Curculionidae). The weevil had not been recorded previously in North America.

Here we present the first records of Denheyernaxoides from North America: D. americanus, collected from coniferous litter, soil, and moss in Nova Scotia, Canada. These new records significantly expand the known distribution of the species. Denheyernaxoides americanus is redescribed to include Canadian specimens and to rectify discrepancies in the species’ description identified during examination of the holotype. The deutonymph of D. americanus is also described. Sequences, representing a 658 bp region of the mitochondrial cytochrome c oxidase subunit I (COI), were obtained from representative specimens collected in Canada. Comparison of these sequences with those from the Barcode of Life database (BOLD) suggests that a second species of Denheyernaxoides may occur in British Columbia, Canada. A revised key to world species of Denheyernaxoides is provided.

Hebard (1915) and J. W. H. Rehn (1939 and 1939a) listed species of Orthoptera from Newfoundland but neither author reported any species of Gryllidae. Walker (1915) did not list any members of this family as inhabiting the Magdalen Islands.The first record of a cricket from Newfoundland was by Ander (1960) who recorded two immature females from Shoal Harbour, July 27, 1951. He somewhat doubtfully assigned these specimens to Nemobius fasciatus (DeGeer), stating: “I suppose that the specimens belong to the species Nemobius fasciatus (Degeer), widely distributed in North America, which is common in Nova Scotia (Piers 1918). The specimens agree very well with the description of fasciatus in Morse (1920) and Blatchley (1920), and as it is the only Nemobius known from Nova Scotia I have good reasons to suppose that the larvae belong to the species mentioned.”

Alguns estudos evidenciam que condições climáticas são fatores relevantes no padrão de nidificação de várias espécies de vespas solitárias. O presente estudo avaliou o padrão de nidificação da vespa Monobia angulosa Saussure (Vespidae: Eumeninae) no pólo agrícola Mucugê-Ibicoara, Chapada Diamantina, Bahia, durante período de seca prolongada, bem como, a descrição do ninho natural da espécie como o primeiro registro de ninho de M. angulosa construído em ninho abandonado da abelha Xylocopa (Neoxylocopa) cearensis Ducke (Apidae: Xylocopinae). Para o registro e descrição do ninho natural, um único ninho de M. angulosa foi estudado em um pomar de maçã (Malus domestica Borkh). Para o estudo do padrão de nidificação foi utilizada a técnica de ninhos armadilha, sendo amostrados 25 pontos ao longo do pólo agrícola, com as armadilhas postas em remanescentes de vegetação nativa. Cada ponto amostral apresentou uma distância mínima de 4 km do ponto mais próximo. Emergiram em laboratório um total de 19 fêmeas e 23 machos de um total de 19 ninhos fundados, com a emergência dos machos precedendo as das fêmeas. O ninho natural, ao contrário dos ninhos armadilha que foram dispostos horizontalmente, foi construído em série linear vertical sendo utilizada, como substrato, uma estaca de madeira. As nidificações se concentraram nos meses quentes, entre fevereiro e abril de 2012, porém com baixa precipitação, evidenciando influência no padrão de nidificação da espécie, indicando uma rápida resposta às alterações climáticas. Nesting Pattern of Monobia angulosa Saussure (Vespidae) During Prolonged dry Season in the Chapada Diamantina, Bahia, with Notes on Nesting in Old Carpenter-Bee Borings Xylocopa cearensis Ducke (Apidae) Abstract. Weather can be treated as an important factor in the nesting pattern of several solitary wasps species. Nesting pattern of wasp Monobia angulosa Saussure (Vespidae: Eumeninae) was accessed in present study in the agricultural area of Mucugê-Ibicoara, Chapada Diamantina, Bahia, during an extended period of dry season. In here we also presented the first record of a natural nest in pre-existing cavities prior used by Xylocopa (Neoxylocopa) cearensis Ducke (Apidae: Xylocopinae). For a description of the M. angulosa’s natural nest a single nest found in apple orchard (Malus domestica Borkh) was used. For the nesting pattern study we used the trap nests technique with 25 points along the agricultural sampled area; traps were placed in remaining native vegetation. Each sample point was at least 4 km apart. Emerged in the laboratory a total of 19 females and 23 males for a total of 19 established nests, males emerged prior females. Unlike the horizontal trap nests, the natural one was built in vertical linear series and a wooden stake was used as a substrate. Nesting concentrated in the warmer months, between February and April, 2012, with very low precipitation, evidencing influence on nesting pattern of this species, probably due fast response to climatic changes.

A fragment of a right dentary with one postcanine tooth from the Upper Triassic (Rhaetian) Scots Bay Member of the McCoy Brook Formation at Wasson Bluff, Nova Scotia, Canada, represents the first record of the tritylodontid cynodont Oligokyphus from the early Mesozoic of eastern North America. In addition, three dissociated postcranial bones from the same horizon and locality are referable to derived cynodont therapsids. One of these elements, a nearly complete right humerus, can be assigned to Tritylodontidae. Two other bones, an ulna and incomplete ischium, belong to indeterminate derived cynodonts but show no features allowing more precise taxonomic identification. The presence of Oligokyphus in the McCoy Brook Formation provides additional evidence for the remarkably wide geographic distribution of many latest Triassic and Early Jurassic continental tetrapods.

AbstractOzognathus cornutus (LeConte, 1859) (Coleoptera: Ptinidae: Ernobiinae), species native to North America, is a saproxylophagous species and is known to feed on decaying tissues within conspicuous galls and on vegetal decaying organic material such as dried fruits or small wood shavings and insect excrements in galleries made by other woodboring species. A few years after the first record in 2011, its naturalization in Italy is here reported. The insect was found as successor in galls of Psectrosema tamaricis (Diptera Cecidomyiidae), Plagiotrochus gallaeramulorum, Andricus multiplicatus and Synophrus politus (Hymenoptera Cynipidae). The galls seem to have played an important ecological role in speeding up the naturalization process. The lowest proportion of galls used by O. cornutus was recorded for P. tamaricis (23%), the only host belonging to Cecidomyiidae, while the percentages recorded for the other host species, all Cynipidae forming galls on oaks, were higher: 43.6%, 61.1% and 76.9% in A multiplicatus, S. politus and P. gallaeramulorum, respectively. Although O. cornutus is able to exploit other substrates like dried fruits and vegetables, for which it could represent a potential pest, it prefers to live as a successor in woody and conspicuous galls, which thus can represent a sort of natural barrier limiting the possible damages to other substrates.
