Glyphonix bimarginatus (Figure 1) is a common click beetle pest of various economically important crops. The larvae of click beetles (Coleoptera: Elateridae) are elongated, wire-like and commonly known as wireworms. Wireworms are considered as subterranean economic pests during their larval stages in many parts of the world including the United States. The larvae of Glyphonix bimarginatus are commonly found with larvae of other click beetles in the field. Larvae of Glyphonix bimarginatus occurs in soil rich in organic matter and rarely in sandy soil. Young roots and germinating seeds are commonly fed upon by the larvae. This document describes its distribution, life cycle and biology, hosts, economic importance, and management. Also available on the Featured Creatures website at http://entomology.ifas.ufl.edu/creatures. https://edis.ifas.ufl.edu/in1233

The Common

I am asked to write for the Can. Ent. a paper on breeding butterflies, and on taking observations of the larval stages, and I comply with pleasure, hoping that what I shall say may be the means of inducing some collectors to cultivate this field. There are many local collections of butterflies in Canada and the United States, and a few general North American collections, more or less complete. But their owners are mostly satisfied with mere collecting and accumulating specimens of the imago. Very few know anything of the larval and other stages of the butterflies, unless of some of the common species. And where anything is known, very little is given to the world. Some collectors, however, have also been breeders of butterflies, sphinges and moths on a large scale. As for example, our friends, John Akhurst and Professor Julius E. Meyer, of Brooklyn, each of whom could fill a good-sized volume, if they would relate one half of what they know on these subjects. Such an one was the late William Newman, of Philadelphia, who lived to a good old age, and had spent his spare hours for many years in collecting and breeding lepidoptera. But none of these gentlemen have published a line that I am aware of, and the entomological world is not much the wiser for their private experience. So that practically here is a great field almost unworked.

HIV infection can occur at any time in the life cycle from the newborn period, through childhood and adolescence to adulthood, older age. The unique issues and special vulnerabilities involved with each aspect of the life cycle, from family planning to pregnancy and the newborn to older aged person with HIV, are addressed from the biopsychosocial standpoint. While some features of HIV illness are common to any age group, specific challenges arise at various stages of the life cycle, as well as different patterns of transmission, clinical course, and service needs. This chapter will consider such differences at various stages of the life cycle. At the beginning of the AIDS epidemic almost 30 years ago, infected blood products represented a common mode of transmission, with many children diagnosed with HIV infection after receiving transfusions for hemophilia and blood disorders. Because of current practices of screening blood products prior to transfusion, the face of neonatal and early-childhood HIV has changed considerably, to one of children who are infected mostly perinatally through vertical transmission, rather than through exposure to blood products. While the incidence of perinatally acquired infections is decreasing in areas of the world where there is access to HIV care and antiretroviral medication, some transmission of HIV from mother to child remains, both in the United States and throughout the world. In 2007, approximately 79 infants were born with HIV in the United States, compared with 330 in 1994 (CDC, 2007). The primary means of HIV infection of a newborn is vertical transmission during gestation, birth, or breastfeeding of an infant by an HIV-positive mother. It is strongly recommended that all pregnant women be screened for HIV infection as part of routine prenatal care. Such screening is not legally mandatory, however, and may not be performed without the mother’s consent. It is advantageous to obtain HIV testing as early as possible in the course of a pregnancy so that preparation can be made to reduce the risk of transmission to the infant. Without preventive care during gestation or delivery, the risk of transmission from mother to child is 15%–35% (Newell, 1991; Gabiano et al., 1992).

The world distributions of yellow starthistle (Centaurea solstitialis L. ♯ CENSO) and Russian knapweed (Centaurea repens L. ♯ CENRE) are mapped based on information from world regional floras. A survey of weed specialists and herbaria was made in the United States, and the extent of the infestations and economic importance of these weeds was determined for the 48 contiguous states. Yellow starthistle currently occurs in 209 counties in 23 states and has apparently increased in abundance since 1970. Russian knapweed was reported in 412 counties in 21 states and does not seem to be spreading. Both of these weedy plant species are of greater economic importance in the western United States than in the east.

Notwithstanding the undoubted economic importance of the Tabanidae, which is second only to that of the Culicidae among blood-sucking insects, our information concerning the habits and life-histories of Canadian species is very meagre indeed. What knowledge we possess has been chiefly derived from the studies made by entomologists of the United States, who have discussed among others some of the species that occur on both sides of the international boundary. Of the species dealt with in the present paper, Hart (1896, p. 227) observed oviposition by Chrysops moerens, Walk., in Illinois, and a description of the egg was given. This brief account was supplemented by Hine (1906, p. 36) in Ohio, who published a detailed description of the process of oviposition of the same species and was, moreover, successful in rearing Tabanus lasiophthalmus, Macq., from the egg to the adult—the first time that this had been accomplished for a Tabanid species. Jones & Bradley (1923, p. 310), working in Louisiana, discovered in the course of their investigations on the Tabanidae a single larva of T. reinwardtii, Wied., from which an adult was reared, but no description of the larva was offered. Webb & Wells (1924) published an account of the partial life-cycle of T. phaenops, O.S., including descriptions of the early stages, as well as of T. insuetus, O.S., in which all stages other than the egg were obtained and described.

Background. Nearly all of the research on sex differences in mass media utilization has been based on samples from the United States and a few other Western countries. Aim. The present study examines sex differences in mass media utilization in four Asian countries (Japan, Malaysia, South Korea, and Singapore). Methods. College students self-reported the frequency with which they accessed the following five mass media outlets: television dramas, televised news and documentaries, music, newspapers and magazines, and the Internet. Results. Two significant sex differences were found when participants from the four countries were considered as a whole: Women watched television dramas more than did men; and in Japan, female students listened to music more than did their male counterparts. Limitations. A wider array of mass media outlets could have been explored. Conclusions. Findings were largely consistent with results from studies conducted elsewhere in the world, particularly regarding sex differences in television drama viewing. A neurohormonal evolutionary explanation is offered for the basic findings.

Sandra Ramos (b. 1969) is one of the few artists to reflect critically on both sides of the Cuban di-lemma, fully embodying the etymological origins of the word in ancient Greek: di-, meaning twice, and lemma, denoting a form of argument involving a choice between equally unfavorable alternatives. Throughout her works she shines a light on the dilemmas faced by Cubans whether in Cuba or the United States, underlining the bad personal and political choices people face in both countries. During the hard 1990s, while still in Havana, the artist focused on the traumatic one-way journey into exile by thousands, as well as the experience of profound abandonment experienced by those who were left behind on the island. Today she lives in Miami and operates a studio there as well as one in Havana. Her initial disorientation in the USA has morphed into an acerbic representation and critique of the current administration and a deep concern with the environmental collapse we face. A buffoonlike Trumpito has joined el Bobo de Abela and Liborio in her gallery of comic characters derived from the rich Cuban graphic arts tradition where she was formed. While Cuba is now represented as a rotten cake with menacing flies hovering over it ready to pounce, a bombastic Trumpito marches across the world stage, trampling everything underfoot, a dollar sign for a face.

From the Baltic to the South China Sea, newly assertive authoritarian states sense an opportunity to resurrect old empires or build new ones at America's expense. Hoping that U.S. decline is real, nations such as Russia, Iran, and China are testing Washington's resolve by targeting vulnerable allies at the frontiers of American power. This book explains why the United States needs a new grand strategy that uses strong frontier alliance networks to raise the costs of military aggression in the new century. The book describes the aggressive methods which rival nations are using to test American power in strategically critical regions throughout the world. It shows how rising and revisionist powers are putting pressure on our frontier allies—countries like Poland, Israel, and Taiwan—to gauge our leaders' commitment to upholding the American-led global order. To cope with these dangerous dynamics, nervous U.S. allies are diversifying their national-security “menu cards” by beefing up their militaries or even aligning with their aggressors. The book reveals how numerous would-be great powers use an arsenal of asymmetric techniques to probe and sift American strength across several regions simultaneously, and how rivals and allies alike are learning from America's management of increasingly interlinked global crises to hone effective strategies of their own. The book demonstrates why the United States must strengthen the international order that has provided greater benefits to the world than any in history.

Every child has a right to an education. In the United States, the issue is not necessarily about access to a school but access to a quality education. With strict compulsory education laws, more than 50 million students enrolled in primary and secondary schools, and billions of dollars spent annually on public and private education, American children surely have access to buildings and classrooms. However, because of a complex and competitive system of shared policymaking among national, state, and local governments, not all schools are created equal nor are equal education opportunities available for the poor, minorities, and underprivileged. One manifestation of this inequity is the lack of qualified teachers in many urban and rural schools to teach certain subjects such as science, mathematics, and technology. The purpose of this article is to describe a partnership model between two major institutions (The American Museum of Natural History and The City University of New York) and the program designed to improve the way teachers are trained and children are taught and introduced to the world of science. These two institutions have partnered on various projects over the years to expand educational opportunity especially in the teaching of science. One of the more successful projects is Seminars on Science (SoS), an online teacher education and professional development program, that connects teachers across the United States and around the world to cutting-edge research and provides them with powerful classroom resources. This article provides the institutional perspectives, the challenges and the strategies that fostered this partnership.
