AbstractThe Pegomya hyoscyami species complex, which contains the economically important beet and spinach leaf-miners, is defined and taxonomically revised. Four distinct species are recognized by differences in the adult morphology of both sexes: Pegomya betae (Curtis), P. cunicularia (Rondani), P. exilis (Meigen), and P. hyoscyami (Panzer). A key for identification, diagnoses, figures of the male and female genitalia, and distribution records are provided. The nomenclature adopted here is a result of a critical review of 21 relevant species-group names. Five lectotypes are designated and four new synonymies are established; five names are considered nomina dubia and one is a nomen nudum. All four species occur in Europe, whilst only two are known from North America (betae, hyoscyami) and Japan (cunicularia, exilis).

Phyllonorycter Blancardella

AbstractThe life stages of Phyllonorycter blancardella (Fabr.) were monitored in an orchard at Guelph, Ontario in 1981 and 1982 and the results showed discrepancies with the previous concept of a trivoltine species occurring throughout its range in eastern North America. Sleeve cages were used to monitor the development of the second, mid-summer generation of leaf miners in a low-maintenance orchard at Guelph in 1982 and 1984 and 2 commercial orchards at Simcoe, Ontario in 1984. The flight period of the first-generation adults occurred over approximately a 6-week period. From eggs laid early in the flight period, a large proportion of the larvae developed quickly and emerged to give a second-generation adult flight. As the flight period continued, there was an increase in the number of progeny whose development was delayed in the early instars. These larvae did not pupate until late fall and overwintered as pupae. Of the second-generation larvae, about 70–90% at Guelph and 35% at Simcoe had a delayed development (summer diapause) and formed a large proportion of the overwintering population.

Fenusa Pusilla

Among the numerous insects attacking the leaves of birch in North America are Profenusa alumna (MacG.) and Fenusa pusilla (Lep.), both of which are leaf-miners belonging to the tribe Fenusini. Various attempts have been made to separate the known fenusine larvae, all of which are very similar (Yuasa, 1922; Ripper, 1931; Lorenz and Kraus, 1957; Lindquist, 1959), but the larval morphology of F. pusilla only has been described in detail (Friend, 1933; Daviault, 1937). In this paper the larval morphology of P. alumna is described from material collected some 60 miles north of Sault Ste. Marie, Ontario, in 1955.

AbstractA key is given to the 19 genera of Fenusini, and synonymies and discussions are given for each genus. The tribe Cacosyndiini is synonymized with Fenusini, and Afusa Malaise is a new synonym of Nefusa Ross. The larvae of Fenusini are leaf miners, and species are found throughout the northern hemisphere south to Burma and Nepal in Asia, and in southern South America. Several species have been accidentally introduced to areas outside their native ranges; at least 5 species are adventives in North America.
