AbstractThe antler moth, Cerapteryx graminis (L.), first discovered in Newfoundland in 1966, has now successfully established itself over an area of approximately 60 km in the greater St. John’s area and surrounding localities. It has become a pest of limited economic importance in hay and pasture fields, and lawns. Black light traps, operated at Mt. Pearl and Kilbride during 1966–1978, were used to monitor population build-up. Notes on the life history of the antler moth in Newfoundland, with some comparisons with that in Great Britain and Europe, are provided. Natural controls are also discussed.

In the case of any harmful insect of economic importance, in order to war against it, or apply remedial measures at all intelligently, a knowledge of the life-history of the pest is necessary. This proposition will, I think, meet with such ready acceptance as to render proof unnecessary, but I might in illustration mention two cases which came under my own observation, where in the one case a knowledge of the round of life of the attacking insect saved a whole forest, and in the other proved of great importance.

A number of species of this genus of Encyrtid parasites are known to be, and others are suspected to be, secondary parasites ; but apparently the complete life-history has not been observed in any one case. As the genus has an almost world-wide distribution and is doubtless of considerable economic importance, the following observations made in Southern California in part of 1935 and 1936 are recorded.

AbstractA crown-boring noctuid, Amphipoea interoceanica (Smith), has suddenly become a serious pest of commercial strawberries in Manitoba. Eggs are laid in August on dead strawberry leaves and hatch in early May. Young larvae feed in the leaf stalks; older larvae bore in the crowns and kill the plants. There are six instars, pupation occurs in late July and adults emerge in August. The plants are first attacked in the second year of growth and by the fifth year the entire crop may be lost.

Reproduction in the Pseudococcidae is usually regarded as being predominantly, if not exclusively, bisexual, though Ferris (1950) has pointed out that within the family as defined by him males are known for only a small percentage of the species described to date. Detailed biological observations have been restricted to those members of considerable economic importance and in regard to reproductive habits there are few specific references in the literature. Hough (1922) in his account of the life history of the clover root mealybug Chnaurococcus trifolli (Forbes) Ferris, stated that no males were seen throughout the period of the observations. James (1937) made a comprehensive study of the reproduction of Planococcus citri (Risso) Ferris, Pseudococcus maritimus (Ehrh) Ferris, P. gahani Green, P. adonidum (Linn.) Ferris, and Trionymus peregrinus Green, and found that parthenogenesis did not occur in any of these species. This confirmed conclusions of earlier workers with Pl. citri (Schrader 1923, Sutherland 1932), and with P. gahani and Phenacoccus gossypii Twns & Ckll. (Basinger 1934). However, Myers (1932) reported parthenogenesis in some of his experiments with Pl. citri but his procedure of isolating females from the cultures after the second moult is clearly open to criticism.

AbstractA history of the changes in nomenclature within the genus Spodoptera is outlined. A key to the imagines of the eight species occurring in Africa and the Near East is presented, together with keys to the larvae and pupae of most of these species, including all those of economic importance in this region, as well as brief notes for identifying the eggs of six species. For each species, a separate account is given of its taxonomic features and affinities, general world and more detailed African distribution, as well as host-plants, including those of economic importance, and its vernacular names. The subspecies Spodoptera leucophlebia malagasy Viette, recorded only from the Malagasy Republic, has been raised to full specific status, and should now be known as Spodoptera malagasy Viette, stat. n.
