AbstractThe preferred host of the cluster fly, Pollenia rudis Fab., in Ontario is reported to be the earthworm Eisenia rosea Sav. Periodic field digging revealed the immature stages of P. rudis feeding, or in close association with, E. rosea. In addition P. rudis was reared in the laboratory on E. rosea but could not be reared on any of the other species of earthworm found in the field.For the first time in North America the complete life history, along with each of the immature stages of P. rudis, is described. The differences between P. rudis from North America and those from France are indicated.Finally, the authors speculate that there are two strains, or species, of P. rudis in France: one is host-specific to the earthworm Allolobophora chlorotica Sav. and the other to E. rosea. Only the strain with E. rosea as its preferred host has as yet been reported from Canada.

This study provides new data on Dutch elm disease in the Czech Republic. <I>Ophiostoma novo-ulmi</I> is reported for the first time in the area of the Czech Republic, as well as both subspecies ssp. <I>novo-ulmi</I> (indigenous in the area of the Ukraine and Moldavia), and ssp. <I>Americana</I> indigenous in North America. The majority of the recorded strains belonged to <I>O. n.-u.</I> ssp. <I>novo-ulmi</I>, while <I>O. n.-u.</I> ssp. <I>Americana</I> and hybrids of these two subspecies were found less frequently. On the other hand, <I>Ophiostoma ulmi</I> was not found at all in the investigated samples. Identification on the subspecies level was performed by methods of molecular biology, i.e. PCR and RFLP of gene regions<I> cu</I> and <I>col1</I>.

The purpose of this paper is to present what is known at the present time concerning the life histories and habits of the Mesoveliidae, particularly those of three species of the genus Mesovelia Muls. found in North America. Studies on our most common species, Mesovelia mulsanti bisignata Uhler, were carried out in Michigan and Kansas, while biological notes on the other two species were taken in the region of Douglas Lake, Michigan, their only known habitat. Isolated rearings and life history studies of all three species were made at Lawrence, Kansas.

Conwentzia psociformis (Curt.) and Conwentzia pineticola End. differ as adults in only two characters, and since there are variable and intermediate forms occur, reliable determination is sometimes impossible. In the past, these two species have often been regarded as two forms of the same species.The immature stages of C. pineticola are, however, very different from those of C. psociformis and show that the two are distinct species and can readily be separated on larval characters. The larval stages and egg of C. pineticola are described for the first time, and an account of its life history given.The feeding habits of these two species are described, and mention is made of two other Coniopterygid species that occur in orchards.

An account is given of a series of experiments on the feeding habits of Cryptophagus acutangulus, Gyll. It was shown that this species will feed readily on a wide variety of fungi and will only rarely ingest other foods. It thrived when fed exclusively on Penicillium conidia. C. acutangulus is capable of the internal mechanical and external transmission of fungi. Approximately 15 per cent. of the Penicillium conidia germinate after passing through the alimentary canal, and these conidia are so affected that they have an enhanced germination rate. The larvae feed exclusively on the spores and hyphae of fungi.A complete life-history from egg to adult is given. The larvae and pupae are described for the first time, and a description of the adult is also given.

Tabulate Corals

Rugose and tabulate corals from the Lower Permian (Wolfcampian) part of the Bird Spring Group in Arrow Canyon, Arrow Canyon Range, Clark County, Nevada, comprise eight species in eight genera. Stylastraea rowetti n. sp. is the first unequivocal record of this genus west of Texas in North America. Heritschiella girtyi, the only endemic North American waagenophyllid genus and species, is recorded outside Kansas for the first time. Paraheritschioides stevensi formerly was known only from northern California. The other species also occur elsewhere in the Permian of Nevada and nearby. This southeast Nevada shelf area has the first known intermixture of corals from the Durhaminid Coral Province and subprovinces of far western North America and the Cyathaxonid Coral Province of middle and southwestern North America.

In August 2004, examination of powdery mildew-infected ‘Russet Burbank’ potato leaves from a furrow-irrigated field in Grant Co., WA, revealed two powdery mildew fungi, one referable to Erysiphe orontii and the other to Leveillula taurica (Lév.) G. Arnaud. Discovery of the two species sporulating together on diseased leaves is consistent with an observation made in the Middle East. This report documents, for the first time, L. taurica on potato in N. America and provides information on distinguishing it from E. orontii. Accepted for publication 9 December 2004.

First Time

Species of Chrysolampus are widely distributed in arid regions of western North America and parasitize tychiine weevils that infest the seed pods of legumes. Detailed host information is presented for the first time: Chrysolampus sisymbrii parasitizes Tychius tectus in Astragalus inflexus and Chrysolampus schwarzi parasitizes Tychius lineellus in Lupinus leucophyllus. Data are presented on phenology, sex ratio, mating and oviposition behaviour of adults, and behaviour and development of larvae and pupae. Ovipositional promiscuity (i.e., eggs are equally likely to be laid in pods infested or uninfested with weevil larvae) is documented in both species of Chrysolampus and discussed from a historical perspective. The immature stages of C. sisymbrii and C. schwarzi are described and illustrated using both light and scanning electron microscopy, and hypermetamorphic development is documented; the first-instar larva is morphologically distinct from the remaining larval instars. On the basis of both life history and morphology it is appropriate to refer to the first-instar larvae as planidia. The first-instar larva is sclerotized, mobile, and actively involved in host location and attack, and it is regarded as homologous to the planidia of the Eucharitidae and Perilampidae. Previous phylogenetic hypotheses regarding Chrysolampus, the Eucharitidae, and the Perilampidae are reevaluated and discussed in light of these new morphological, behavioural, and ecological data.

The morphology of larva and pupa, as well as larval mines of Elachista zonulae (Sruoga, 1992) are described and illustrated for the first time. Carex firma Host is reported as a new host plant ofthe species; previously only Carex sempervirens Vill. was known to be host plant of E. zonulae. Some information on life history of this elachistid moth is also provided. The mature larva is 4.5—5.5 mm long. Pupation takes place usually at base of leaf blade of the food plant. The species is univoltine and hibernates as young larva.

A new species of the genus Corythucha, C. bonaerensis n. sp., is described along with its egg and all immature stages. It was found in the province of Buenos Aires (Argentina) feeding on Quercus robur, its host plant. Comments on the life history of C. bonaerensis are provided together with photographs, and illustrations. The main differences with the other South American species, and other Corythucha species that feed on Quercus worldwide, are also discussed.
