History Of

The black cutworm, Agrotis ipsilon (Hufnagel), is of major economic importance in many areas of the world. In recent years, adequate methods for assessing the toxicity of insecticides to the black cutworm have been developed (Begg and Harris, 1958; Begg et al., in preparation; Harris and Mazurek, 1961). However, with the exception of the works by Crumb (1929) and Satterthwait (1933), less research has been devoted to the life history of this insect.

Harmful Insect

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.

The life history of the tobacco flea beetle, Epitrix hirtipennis (Melsheimer) (= Epitrix parvula Fab.) was studied under the controlled conditions of 27 ± 2.8°C, 80 ± 6% and a 14L:10D photophase. Eggs matured in ca. 4 days, the larval stage, including 3 instars, developed in 13 days, prepupal development took 3 days and the pupal stage lasted approximately 5 days. There was a 24 day interval between oviposition and adult emergence. Females laid 3.1 eggs/day with a 13 day period between adult emergence and first oviposition. The mean number of total eggs/female was 138.6 ± 14.7. Female oviposition continued until a few days before death and adult longevity was approximately 70 days. A visual means of distinguishing between male and female beetles was also developed.

Abstract This article explores the life history of Sam, a queer and transgender youth of color who contests standardized futures in secondary schools. Sam's school life is rife with expectations that seek to confine Sam and their way of being in the world. In response to their school life, Sam forwards new ways of thinking of the future that rely on remaining present, contesting identity politics and questioning the contours of humanity.

The World

The hide beetle, Dermestes maculatus Degeer, is a cosmopolitan insect which each year causes considerable losses to stored products throughout the world. The economic importance of this species is due especially to the habit which the mature larvae have of boring into many commodities in order to pupate. However, the larvae and adults also feed on and thus damage a wide variety of substances with a high protein content (4), e.g., bones, carcasses, skins and hides of all kinds, etc.

Tales of God’s Friends: Islamic Hagiography in Translation, an anthologythat honors Sufis from every corner of the Muslim world, provides an easilyaccessible overview of Sufism’s history and the particularities of individualSufi experiences that helped spread Islam throughout the world. A valuablecontribution to the contemporary literature of Sufi studies, this volume alsooffers an excellent overview of the Sufi path and philosophy as well as classictexts of Islamic mysticism. The wide-ranging and eclectic collection of sources is a particular strength, and manuscripts have been edited with referencesto several authors who knew the life history of these Sufis.The book contains twenty illustrations; a preface; six parts (divided intotwenty-seven chapters); an appendix and a glossary; notes about the contributors;an index of names; an index of concepts, themes, places, and booktitles; and a Qur’an index. The editor claims that it is the first truly globalEnglish-language anthology of Islamic hagiography, both historically andgeographically – it is translated from seventeen languages of origin, with thehelp of two dozen Islamic scholars specializing in broad spectrum of languages(pp. xi-xiv) ...

From no part of the world have we of late years derived more additions to the Geological Record than from North America. Besides important additions to the earliest pages of that record, the rich collections made by the United States Surveyors, both of fauna and flora, from the Cretaceous, Eocene, and Miocene deposits, have thrown much light upon the life history of the Earth; and it is even contended that they have bridged over the interval which, notwithstanding the Maestricht beds, the Pisolitic, and the Faxoe Limestones, still remains sharply marked between the Cretaceous and Tertiary formations of Europe so far as they have yet been examined.

Comprehensive Study

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.

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.
