The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), (Hemiptera: Miridae) is considered the most damaging pest of cotton (Gossypium hirsutum L.) in the mid-southern United States, although it is established throughout the United States, southern Canada, and northern Mexico. The introduction of transgenic crops for the control of moths in the Heliothine complex and eradication of the boll weevil, Anthonomus grandis, from much of the United States led to greatly reduced pesticide use in cotton fields, which allowed L. lineolaris to emerge as a new primary pest of cotton in the mid-southern United States. Since the publication of a review by Layton (2000) on damage caused by Lygus lineolaris, many new studies have been published on the changes in host range, population dynamics, sampling methods and thresholds, cultural practices, sex pheromones and attractant blends, novel pesticides and insecticide resistance mechanisms, olfactory and feeding behaviors, introduction of biological control agents, host-plant resistance mechanisms, and new molecular and genetic tools for integrated pest management of Lygus species in cotton and other important crops. Here, we review and discuss the latest developments in L. lineolaris research in the last two decades.

Texas Revolution

Between 1820 and 1827 approximately 1,800 U.S. citizens immigrated to northern Mexico as part of that country’s empresario program, in which the federal government granted foreigners land if they promised to develop and secure the region. Historians have long argued that these settlers, traditionally seen as the vanguard of Manifest Destiny, were attracted to Mexico for its cheap land and rich natural resources. Such interpretations have lent a tone of inevitability to events like the Texas Revolution. This article argues that the early members of these groups were attracted to Mexico for chiefly political reasons. At a time when the United States appeared to be turning away from its commitment to a weak federal government, Mexico was establishing itself on a constitution that insured local sovereignty and autonomy. Thus, the Texas Revolution was far from the result of two irreconcilable peoples and cultures. Moreover, the role that these settlers played in the United States’ acquisition of not just Texas, but ultimately half of Mexico’s national territory, was more paradoxical than inevitable.

AbstractMembers of the genusNeoechinorhynchusStiles & Hassall, 1905 are endoparasites of freshwater fishes, brackish water fishes, and freshwater turtles distributed worldwide. In North America, 33 species have been described. One of the most widely distributed species in the eastern United States and Canada isNeoechinorhynchus (Neoechinorhynchus) cylindratus,a common acanthocephalan that infects centrarchid fishes. In the current study, adult specimens ofN. (N) cylindratuswere collected from largemouth bass (Micropterus salmoides) from the Purificación River in northern Mexico. In the same freshwater system, two additional congeneric species (Neoechinorhynchus (Neoechinorhynchus) emyditoidesandNeoechinorhynchus (Neoechinorhynchus) panucensis) were collected and analysed. Sequences of the large subunit, internal transcribed spacers ITS1 and ITS2, 5.8S from nuclear DNA, and sequences of the cytochromecoxidase subunit I (cox1) from mitochondrial DNA were generated and aligned with other sequences obtained from GenBank. Maximum likelihood and Bayesian inference analyses inferred for each dataset showed thatN. (N) panucensis,N. (N) emyditoidesandN. (N) cylindratuswere nested within several clades, indicating that these species do not share a common ancestor. Our phylogenies also revealed that the genusNeoechinorhynchusis paraphyletic, requiring further taxonomic revision using phylogenetic systematics and re-examination of morphological and ecological data. The presence of severalN. (N) cylindratusadults in northern Mexico allowed us to typify this species for the first time using a combination of morphological and molecular characteristics. The current record shows a wide distribution range ofN. (N) cylindratusacross Canada, the United States and Mexico in the Nearctic region.

Northwestern Mexico

The semiarid expanses of northern Mexico have long been a haven for drug trafficking and shipment into the southwestern United States. During the past 3 decades, a more specialized and dedicated drug industry has used the long U.S.-Mexican border to move illicit narcotics. Northern Mexico is not a heavily indigenous zone, and yet some native populations have been adversely affected by this recent industry, and not just a few have taken a role in it. Two states in northern Mexico that still have indigenous peoples are Sonora and Chihuahua. Both of these semiarid states are more sparsely populated than the rest of Mexico, yet both share a long, expansive border with the United States. Thus, neither state has escaped the activities of the drug industry, and some of the major drug cartels are located in this region (figure 8.1), the largest in urban areas such as Ciudad Juarez in the state of Chihuahua and Culiacán in the state of Sinaloa. Although these urban areas are the economic and logistical centers of two large cartels, an aspect frequently ignored in the literature, and certainly in policy circles, is the variety of scales of production in this industry. Aside from these giant cartels, drug cultivation, production, and transportation are also common at lesser scales, and the difficulties and dangers associated with drug production and trafficking extend to these small farmers. Small plots of marijuana (Cannabis sativa) and poppies (Papaver somniferum) dot the northern Mexican landscape, especially in the foothills and high peaks of the Sierra Madre. Most of the poppy production lies further south, in the states of Michoacan, Guerrero, and Oaxaca. Marijuana (Cannabis) is by far the more common of the two illicit crops grown in Mexico, partly because of its longer history of cultivation in the country’s mountainous regions and partly because of its greater ease of integration into agriculture. Poppy fields are a lot harder to hide, both from neighbors and from more interested authorities. Marijuana is also more easily intercropped with more common agricultural crops. Intercropping is the practice of growing two or more crops in the same field or parcel of land, and it is common when farmers need to maximize total output per unit of area (Wilken 1987: 248). I have seen marijuana integrated with corn, bean, squash, sunflower, and tomato plants.

Abstract A newly discovered ammonite faunule from the Padern region of the southern Corbières in southern France includes representatives of typical northwest European Upper Turonian species Subprionocyclus cf. neptuni (Geinitz, 1850) and Lewesiceras cf. woodi Wright 1979, tethyan/ northwestern Pacific species Phyllopachyceras cf. ezoense (Yokoyama, 1890), Anagaudryceras involvulum (Stoliczka, 1865) and, Desmoceras (Pseudouhligella) sp., together with Coilopoceras inflatum Cobban and Hook, 1980, a species previously known only from New Mexico in the United States, where it is regarded as Middle Turonian. The faunule occurs above one with Romaniceras (R.) mexicanum Jones, 1938 and Coilopoceras springeri Hyatt, 1903, also originally described from New Mexico and northern Mexico, and recently described from the Uchaux massif in Vaucluse in southern France. The records suggest that the base of the Upper Turonian may be drawn at different, higher level in the United States Western Interior than in Europe. The coming together of these mixed faunal elements may be a result of high sea levels, and changing oceanic circulation patterns.
