Results from controlled inoculation experiments show that conifers of six genera (Abies, Larix, Picea, Pinus, Psendotsuga, and Tsuga) are susceptible to the poplar (Populus) rusts of western Canada. Twenty-one new host records are established. It is suggested that Melampsora albertensis Arth. be reduced to synonymy with M. medusae Thüm., because they appear to be indistinguishable from each other in morphology, life history, host range, and host reaction.

Taenia mustelae Gmelin, 1790 (= T. tenuicollis Rudolphi, 1819) is proposed as the valid name for the small-hooked cestode from European brown weasel, and Taenia martis (Zeder, 1803) n. comb. (= T. intermedia Rudolphi, 1810) is proposed for the large-hooked cestode from European marten. T. mustelae adults were found naturally in the short-tailed weasel, Mustela erminea, and T. martis adults in the pine marten, Martes americana in North America; the latter constitutes a new host record. Larvae were recovered from 10 species of rodents of which Citellus franklinii, Eutamias minimus, Marmota monax, Tamias striatus, Synaptomys cooperi, and Zapus hudsonius are new host records. Experimental infections produced by feeding T. mustelae eggs were followed in eight species of rodents. In one animal mature scoleces occurred as early as 26 days after eggs were fed, yet no fully developed scoleces were present even after 104 days in another animal in the same feeding. Such feedings of eggs produced multiscolex larvae (up to 26 scoleces), or multiscolex and uniscolex larvae simultaneously, but never uniscolex larvae exclusively, although these were found occasionally in nature. Normal, fully developed scoleces were present on larvae 318 days old. Growth of T. mustelae larvae in Peromyscus maniculatus and the host reaction is described in detail. Multiscolex larvae from a natural infection fed to a mink produced adult T. mustelae.

AbstractHymenopterous parasitoids of filth flies (Diptera: Muscidae) were surveyed during 2 years on dairy farms in Ontario and Quebec near Ottawa, Ontario, using freeze-killed sentinel house fly (Musca domestica L.) pupae and naturally occurring fly pupae collected on site. Musca domestica and Stomoxys calcitrans (L.) (stable fly) represented 98.3% of the natural fly hosts from which parasitoids emerged. Muscidifurax raptor Girault et Saunders, Nasonia vitripennis Walker, Pachycrepoideus vindemiae (Rondani), Spalangia cameroni Perkins, S. nigra Latreille, Trichomalopsis viridescens (Walsh), and Urolepis rufipes (Ashmead) (Pteromalidae) were recovered from both sentinel and natural fly pupae. Another eight species, S. drosophilae Ashmead, S. endius Walker, S. haematobiae Ashmead, S. nigroaenea Curtis, S. subpunctata Förster, Trichomalopsis dubia (Ashmead) (Pteromalidae), Aphaereta pallipes (Say) (Braconidae), and Phygadeuon ?fumator Gravenhörst (Ichneumonidae), were recovered only from natural pupae. Over the 2 years, M. raptor comprised 90.7% of emerged parasitoids from sentinel pupae but only 17.0% of emerged parasitoids from natural pupae. From natural pupae, S. cameroni, S. nigra, and S. nigroaenea collectively comprised 60.3% of emerged parasitoids; P. ?fumator comprised 13.5% and the remaining nine species 9.2%. The recoveries of S. endius and S. nigroaenea represent new distribution records for Canada, and several new host records are identified based on structure of the host fly puparium. The parasitoid fauna is compared with that known for western Canada, and recommendations are made for both regions concerning potential natural enemy enhancement for filth fly control.

AbstractThe poplar and willow borer, Cryptorhynchus lapathi (L.), known to be present in British Columbia since 1923, primarily attacks species of Salix L. (Salicaceae) and Populus L. (Salicaceae). Larvae bore into stems, causing them to break easily. The impact of the weevil has been rising in recent years because of the increasing importance of poplar and willow from both economic and ecological perspectives. We conducted a study at 45 locations in British Columbia to determine host use among native Salix spp. and the between- and within-tree dynamics of C. lapathi. There were 11 new host records, but the incidence of attack was similar among species. Attacked trees were larger in general and had more dead wood and stems, more adventitious branches per stem, more total breaks per stem, and more naturally caused breaks per stem than their attack-free neighbours. Breaks caused by C. lapathi tended to be slightly larger in diameter and lower on the stem than naturally caused breaks. Bases of stems were preferentially attacked, and C. lapathi selected large stems in which to oviposit. As large attack-free trees become less abundant, weevils apparently start to attack small-diameter stems. Although C. lapathi is adversely affecting the health of willows in British Columbia, there is no evidence that any Salix species is threatened by weevil-caused extinction.

New Host Records

The prevalence of Sarcocystis in 930 birds of 58 species from western Canada is reported. All birds were examined for macroscopic cysts, and tissue from 916 birds was also examined histologically for microscopic cysts. Different prevalences were obtained for several species, and nine new host records are reported. Histological examination of muscle revealed Sarcocystis in many birds which would have otherwise been reported uninfected because only microscopic cysts were present. The prevalence of Sarcocystis in some anatids in Alberta was significantly different from two other surveys. Different migratory routes and overwintering g rounds in each of the studies are suggested as explanations for these findings. Several unsuccessful attempts to complete the life cycle using dogs, coyotes, mink, ferrets, cats, kittens, and rats are reported. The failure to establish infection in any of these carnivores with the macroscopic cysts from ducks is considered supporting evidence for the hypothesis that this parasite is transmitted by another host in another area.

A new species, Glyptapanteles hypermnestrae Gupta and Pereira, is described from Maharashtra, India, and comparedwith closely allied species. This new species was bred from parasitized larvae of Elymnias hypermnestra (Linnaeus) (Lep-idoptera: Nymphalidae). In addition to this, two hymenopteran parasitoids, Apanteles folia Nixon (Braconidae: Microgas-trinae) and Brachymeria indica (Krausse) (Chalcididae), are for first time reported parasitizing larvae of Arhopalaamantes (Hewitson) (Lepidoptera: Lycaenidae) and pupae of Pareronia valeria (Cramer) (Lepidoptera: Pieridae) respectively.
