The sunflower maggot is native to North America. It has been recorded from Maine and New Brunswick through Quebec to Alberta and California and as far south as New Mexico and Florida. It was collected by Criddle at Aweme, near Treesbank, Manitoba, in 1905 and is known to have been present in cultivated sunflowers in southern Manitoba since 1944. Heavy infestations have occurred since 1948.

AbstractBetulaphis quadrituberculata (Kalt.) is an inconspicuous leaf-feeding aphid on birches in North America and Europe, now recorded on Betula papyrifera Marsh and B. alleghaniensis Britt. in the Province of New Brunswick. Some aspects of its morphology are described in order to complement the incomplete accounts already in the literature. The viviparae are seasonally polymorphic in size and color.In New Brunswick the aphid has an annual monoecious holocycle comprising up to 10 generations. The seasonal history and habits of the various morphs are described. The insect disperses mainly by the flight activity of the stem-mothers in spring, but in succeeding generations almost all individuals are apterous and rather sedentary in habit. Data on rate of development and fecundity are presented and briefly discussed as factors contributing to the seasonal population pattern.

A parasitic nematode, Howardula aptini (Sharga 1932) Wachek, 1955, is reported for the first time in North America, and is a parasite of two serious blueberry thrips. Parasitized thrips probably do not produce eggs as the ovarial tissue is greatly reduced by the nematode and dissections failed to reveal eggs in infected individuals. Parasitism varied and was 71% in one sample. Introduction of the nematode into unparasitized populations is feasible. Previously unknown details of the morphology and life history of the nematode are described and illustrated.

The wharf borer, Nacerdes melanura (L.) (Fig. I), is widely distributed throughout the world. It has been recorded in England, New Zealand, Denmark, Germany. Siberia, Japan, and the Bahama Islands (Balch 1937). Walker (1936) reported N. melanura from Syria, Shanghai, Korea, Japan, South Africa, Brazil, Argentina, Costa Rica, and the United States. In the United States, it has been found in most coastal states, and also in Michigan, Indiana, Missouri, Kansas, and New Mexico. In Canada, it is known to occur in Newfoundland, Nova Scotia, New Brunswick, Quebec, Ontario, Manitoba, and British Columbia. The life history of the wharf borer in Canada has been outlined in detail by Balch (1937) and Spencer (1957).

AbstractPineus pineoides was found for the first time in North America in New Brunswick in 1948, on red spruce, Picea rubens Sarg. It is the first known species of Adelgidae in North America to complete its life cycle on spruce without producing galls or winged forms. The life history is compared with that in Europe. The first-instar nymph and the adult of the summer generation are described and compared with those from Europe.

Arthropleurids Were terrestrial, millipede-like arthropods, The genus Arthropleura Jordan from the Upper Carboniferous reached an enormous size of 2 m or more in length (Hahn et al., 1986), Occurrences are rare and the chronologie and paleogeographic distribution of Arthropleura coincides with the tropical Euramerican floral belt of the Carboniferous (Rolfe , 1969), The Carboniferous was a time of high atmospheric O2 levels (35%) compared to the current 21%, which may have favored the development of large terrestrial arthropods of this time (Dudley, 1998; Graham et al., 1997; Berner, 2001) . Body fossils of Arthropleura range from the Visean to Early Permian (Rolfe, 1969; Schneider and Barthel, 1997), while trackways have been reported from the Visean (Pearson, 1992) to Stephanian (Langiaux and Sotty, 1977; Castro, 1997; Fig. 1). Arthropleura fragments have been described from Ohio, Pennsylvania, Illinois, and Nova Scotia. Only four Arthropleura trackway sites have been described from North America (New Mexico, Kansas, Nova Scotia, and New Brunswick ). Trackways provide information about size and locomotion that is not discernable from fragmentary body fossils .
