In New Brunswick, Ceruraphis eriophori (Wlk., 1848) and Neoceruraphis viburnicola (Gill., 1909) are readily found in spring and autumn on their Viburnum hosts. I have collected both species from the curled leaves of these primary hosts (C. eriophori from Viburnum lantana L. and V. opulus L. and N. viburnicola from V. opulus var. roseum L. and V. trilobum Marsh.) In Colorado, Palmer (1952) recorded borh species from V. opulus var. sterile (= V. opulus var. roseum).The known secondary host plants of C. eriophori in Europe are species of Carex, Eriophorum, Luzula, and Typha (Börner, 1952); in North America, Cyperus virens Michx. is the only one reported (Palmer, 1952). The secondary hosts of N. viburnicola have not been recorded (Palmer, 1952; Shaposhinkov, 1956), nor has the apterous viviparous female been described.

Alarodia nana (Möschler) (Lepidoptera, Limacodidae) is a major pest of Citrus in Jamaica. An outbreak of the larvae, the ‘ slug caterpillar ’, may result in severe defoliation. All stages are found on the foliage and are present throughtout the year; the adults are inactive by day and appear to be weak fliers.Earlier attempts to breed the insect in the laboratory had been unsuccessful, and, whereas attempts at control had indicated that malathion was effective against the larvae, reingestation had invariably taken place, well-grown larvae being found five weeks after treatment.In the present work, done in 1963–4, adults that emerged from field-collected cocoons held in wire-mesh cages over Citrus plants in the laboratory mated on the night of emergence and the females oviposited readily on the following night. A technique for rearing individual larvae and for measuring their head capsules is described. In the laboratory at a mean midday temperature of about 27°C., the incubation period of the eggs was 6–8 days, and the durations of the larval and pupal phases 25–42 and 14–19 days, respectively.Results of a search for secondary host-plants from which reinfestation might take place were negative. Observations of emergence in the laboratory of adults from cocoons collected just before and just after the application to an orchard of a low-volume malathion spray derived from a 57 per cent. emulsifiable concentrate by dilution at the rate of 1: 80 in water showed that many pupae had survived the application, and suggested that reinfestation might arise from moths emerging from such pupae.A field trial comprising two application of the low-volume spray of malathion was carried out; the second application, designed to destroy larvae derived from pupae that had survived the first application, was made after an interval of 312; weeks and was completely successcful.

Seasonal History

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.

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.

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.

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.

The 197 species (including 2 new species) of the Nearctic leafhopper genus Eratoneura are reviewed. Eratoneura betulae sp.n. from New Brunswick (Canada) and E. mcateei sp.n. from the central and northeastern USA are described as new. In addition, 123 new synonyms are recognized and a lectotype is designated for Typhlocyba hartii Gillette. A key is provided for identification of males. All known species are illustrated, and data on their distributions and host plants are summarized. All species of Eratoneura are native to temperate North America, where they feed and oviposit mainly on woody deciduous trees and shrubs

In the late 1970s, Brazilian peppertree, Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae), was targeted for classical biological control in Florida because its invasive properties (see Host Plants) are consistent with escape from natural enemies (Williams 1954), and there are no native Schinus spp. in North America. The lack of native close relatives should minimize the risk of damage to non-target plants from introduced biological control agents (Pemberton 2000). [...]
