During a study on the importance of spiders as predators of the cabbage butterfly Artogeia rapae L. (Lepidoptera: Pieridae) in cultivated cruciferous fields in Quebec, 209 specimens (114 were immatures riding on the back of a female) of Trochosa ruricola (DeGeer) (Lycosidae), 21 specimens of Ostearius melanopygius (O. Pickard-Cambridge) (Linyphiidae), and one specimen of Dictyna decaprini Kaston (Dictynidae) were found by pitfall traps and aspirator at L'Acadie, Quebec (45°20'N, 73°20'W) in cabbage, Brussels sprouts, and broccoli plots. This is the first record of these species in Canada.

Pyramica epinotalisis an arboreal dacetine ant previously known only from Brazil, Costa Rica, Ecuador, and southern Mexico. Here we report the first records ofP. epinotalisfor the United States. Collections were made in three parishes across southern Louisiana in cypress-tupelo swamps using floating pitfall traps placed in floating vegetation and arboreal pitfall traps placed on trunks and limbs of three wetland tree species. One additional specimen of this species was collected in Highlands County, Florida. Based on collections of specimens in Louisiana, including multiple dealate females at different localities,P. epinotalisappears to be well established in this state. We discuss the design and implementation of modified arboreal pitfall traps that were instrumental in this discovery.

Rhagomys rufescens is a rare, arboreal sigmodontine rodent endemic to the Brazilian Atlantic Forest biome. This species is known from eight localities in Brazil. Here we present a new report based on four individuals of this species registered in Serra do Ouro Branco, municipality of Ouro Branco (Minas Gerais, Brazil). One juvenile male, one adult male and two juvenile females were captured in pitfall traps during the rainy season, in a study of small mammal ecology. This is the first record for the Espinhaço Mountain range and the northernmost report for the species in this state, 85 km northeast of the last registered location.

Cimex adjunctus Barber was collected with pitfall traps and by hand in Santee Caves, South Carolina, USA. Santee Caves contain a maternity colony of Myotis austroriparius (Rhoads), the Southeastern Myotis bat. Cimex adjunctus was found only in the maternity chamber. My collection represents the first record of C. adjunctus in association with M. austroriparius. The sex ratio in the C. adjunctus population collected was 1:1 with 128 males, 128 females, and 755 nymphs. Predators of C. adjunctus in the cave environment included three spiders (Azilia affinis Chamberlin, Eidmannella pallida (Emerton), and Gaucelmus augustinus Keyserling). The pathogenic fungus Aspergillus sp. killed C. adjunctus in the cave and laboratory. The mite Histiostoma sp. was phoretic on C. adjunctus. Cimex adjunctus also fed on human blood and elicited an immune response after initial exposure.

This study provides the first record of Mycetophylax simplex (Emery, 1888) for Uruguay and extends the known distribution of this species south  in South America. Mycetophylax simplex is currently the only species of the genus that occurs in Uruguay. Workers and queens were captured with pitfall traps in a sandy beach on east coast of Uruguay. Data and figures of M. simplex for the recognition of the species and map of distribution are presented.

Utilizando armadilhas pitfall, registra-se pela primeira vez quatro operárias da formiga quenquém cisco-da-Amazônia Acromyrmex hystrix (Latreille) (Formicidae: Myrmicinae) em uma caverna no estado do Maranhão, região nordeste do Brasil. Entretanto, não se pode inferir nenhuma informação adicional sobre a freqüência dessa espécie na região, uma vez que, o registro foi acidental. A região onde os indivíduos foram encontrados se encontra na divisa do Maranhão com Tocantins e sugere-se que essa espécie também esteja distribuída nesse estado. First Record of the Quenquém cisco-da-Amazônia Acromyrmex hystrix (Latreille) (Formicidae: Myrmicinae) for Maranhão State, Brazil Abstract. It is recorded, for the first time, using pitfall traps, four workers of ant “quenquém-cisco-da-Amazônia”, Acromyrmex hystrix (Latreille) (Formicidae: Myrmicinae) in a cave at state of Maranhão, northeastern Brazil. However, we could not imply any additional information about the abundance of this species in the region once that this record was accidental. The region where the individuals were found is placed at border of state of Maranhão and state of Tocantins suggesting that this species also occurs in this state.

During a study on the parasitoids of the imported cabbageworm, Artogeia rapae (L.) (Lepidoptera: Pieridae), undertaken in 1993 and 1994, we recovered Cotesia rubecula (Marshall) (Hymenoptera: Braconidae) for the first time in Quebec, Canada. Samples were taken from pesticide-free plots of cabbage, broccoli, and Brussels sprouts located at Ste-Clotilde (45°09′N, 73°41′W) and L'Acadie, Quebec (45°18′N, 73°21′W), as described by Godin and Boivin (1998). In addition, survival of diapausing C. rubecula was evaluated after a 5-month incubation at 4°C (Godin 1997). Both A. rapae and C. rubecula are introduced species and originate most likely from Europe (Richards 1940). Artogeia rapae was discovered in 1860 in Quebec (Harcourt 1963), and C. rubecula was first reported in 1963 in British Columbia (Wilkinson 1966).

A survey of the scorpion fauna of the Island of Fernando de Noronha, Pernambuco (Brazil), was carried out in October 2005. Methods included active collecting and pitfall traps in several areas of the island under different degrees of human-caused alteration. Forty four scorpions, belonging to two species were collected: Isometrus maculatus (DeGeer, 1778), previously listed for the Island, and Tityus stigmurus (Thorell, 1877), here recorded for the first time. This species was probably introduced via cargo shipments from the continent and offers risk to the local population due to the gravity of the accidents.
