AbstractWe report for the first time the occurrence of the well-known Eurasian and north African parasitoidCotesia vanessae(Reinhard) (Hymenoptera: Braconidae) in North America. Specimens were reared fromChrysodeixis chalcites(Esper) andTrichoplusia ni(Hübner) (Lepidoptera: Noctuidae) recovered from several locations in southwestern Ontario, Canada, and detected by DNA sequencing from oneAutographa californica(Speyer) (Lepidoptera: Noctuidae) in southern Alberta, Canada.

Abstract We evaluated the host suitability and related traits of Trichoplusia ni Hübner (Lepidoptera: Noctuidae) and Chrysodeixis chalcites Esper (Lepidoptera: Noctuidae), which is nonnative in North America, for the native parasitoids Campoletis sonorensis Cameron (Hymenoptera: Ichneumonidae) and Copidosoma floridanum Ashmead (Hymenoptera: Encyrtidae), and the nonnative parasitoid Cotesia vanessae Reinhard (Hymenoptera: Braconidae). For the larval parasitoid C. sonorensis and C. vanessae trials, three-day-old larvae of both hosts were used, whereas one-day-old eggs of both hosts were used for the egg–larval parasitoid C. floridanum trial. For suitability parameters on each host exposed separately to each of the three parasitoid species, we measured parasitoid emergence (parasitoid success), parasitoids that did not emerge (parasitoid cocoon mortality), the proportion of male offspring (parasitoid sex ratio), hosts that developed into moths (host success), hosts that died without developing into moths or producing a parasitoid (host mortality), parasitoids emerging from cocoon masses (brood size), and the developmental times of parasitoids and hosts. For C. sonorensis, the native host and the nonnative host were found to be similarly suitable. For C. vanessae, the native host was more suitable than the nonnative host. For C. floridanum, the native host was suitable, whereas the nonnative host was not; however, sublethal effects on both the native and nonnative hosts were observed. The differential suitability of the hosts observed in this study contributes to the understanding of this measure as a dynamic factor in the expansion of parasitoids into novel host species.

AbstractA total of 19 helminth species (1 trematode, 11 cestodes, 7 nematodes) were collected from 45 vagrant shrews, Sorex vagrans (Mammalia, Soricidae), in western Montana, USA. One trematode (Brachylaima sp.), 2 cestodes (Paruterina candelabraria, Staphylocystoides longi), and 6 nematodes (Baruscapillaria rauschi, Eucoleus oesophagicola, Longistriata meylani, Paracrenosoma sp., Parastrongyloides winchesi, Pseudophysaloptera formosana) are reported for the first time from this host. Baruscapillaria rauschi n. comb. is proposed for Capillaria rauschi Read, 1949. This is the first record of merocercoids of P. candelabraria from a shrew, and the first report of the genus Paracrenosoma in North America.

Extensive Damage

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.

Akebia quinata (chocolate-vine, five-leaf akebia) is grown as a perennial ornamental vine in North America. Five collections were made from A. quinata plants in western Washington with symptoms of powdery mildew caused by Microsphaera akebiae Sawada. This report documents the presence of this fungus in North America for the first time, describes and illustrates this fungus and the disease it causes, and reviews the taxonomy and identification of the fungus. Accepted for publication 24 February 2004. Published 16 March 2004.

Lercaritubus problematicus Flügel, Senowbari-Daryan, and Di Stefano, 1990, a problematic organism, was initially described from Lower and Middle Permian rocks of Sicily, was subsequently recognized in Upper Permian reefs of Oman and reefal limestones of the Tethyan realm. It is here described for the first time from North America, from the Middle Permian reefoidal Upper Capitan Limestone of the Guadalupe Mountains in New Mexico. Lercaritubus problematicus has a stratigraphic range of Lower to Upper Permian and occurs widely in Permian tropical reef deposits.
