Polymorphism and Divergence of Novel Gene Expression Patterns in Drosophila Melanogaster
HIGHLIGHTED ARTICLE | INVESTIGATION Polymorphism and Divergence of Novel Gene Expression Patterns in Drosophila melanogaster Julie M. Cridland,1 Alex C. Majane, Hayley K. Sheehy, and David J. Begun Department of Evolution and Ecology, University of California, Davis, California 95616 ABSTRACT Transcriptomes may evolve by multiple mechanisms, including the evolution of novel genes, the evolution of transcript abundance, and the evolution of cell, tissue, or organ expression patterns. Here, we focus on the last of these mechanisms in an investigation of tissue and organ shifts in gene expression in Drosophila melanogaster. In contrast to most investigations of expression evolution, we seek to provide a framework for understanding the mechanisms of novel expression patterns on a short population genetic timescale. To do so, we generated population samples of D. melanogaster transcriptomes from five tissues: accessory gland, testis, larval salivary gland, female head, and first-instar larva. We combined these data with comparable data from two outgroups to characterize gains and losses of expression, both polymorphic and fixed, in D. melanogaster. We observed a large number of gain- or loss-of-expression phenotypes, most of which were polymorphic within D. melanogaster. Several polymorphic, novel expression phenotypes were strongly influenced by segregating cis-acting variants. In support of previous literature on the evolution of novelties functioning in male reproduction, we observed many more novel expression phenotypes in the testis and accessory gland than in other tissues. Additionally, genes showing novel expression phenotypes tend to exhibit greater tissue-specific expression. Finally, in addition to qualitatively novel expression phenotypes, we identified genes exhibiting major quantitative expression divergence in the D. -
Overwintering Strategies of Insects in Northern Climates
Overwintering Strategies of Insects in Northern Climates Joe Nelsen Challenges in winter ● Small ectotherms ● Lack of insulation ● Food shortages (for both herbivores and predators) General strategies - energetic benefits/tradeoffs ● Diapause/dormancy ● Spatial avoidance (migration) Diapause ● Pause in development ○ various life stages ● Strategy for handling all kinds of environmental stressors ● Similar to hibernation in other animals ● Very beneficial for insects who employ this strategy - maximizes fitness ○ Conserving during the “off season” more energy for productive season Diapause - Goldenrod Gall Fly ● Egg laid in stalk of Goldenrod plant ○ Larvae hatch and stimulate gall formation ○ Larvae diapause over winter ○ Larvae pupates and adult emerges in spring ● Gall provides food and protection, but little insulation… ● Larvae produce cryoprotectants to depress freezing point, and nucleators to nucleate ice away from cells… ● Larvae can survive down to -35℃ Ice Nucleation in Gall Flies ● Employs two types of ice nucleators: ○ Fat body cells and calcium phosphate spherules - heterogeneous ice nucleation ● Calcium phosphate spherules ○ Small spheres of crystalline compound that line malpighian tubules of larvae, and nucleate ice in extracellular fluid of tubules ● Fat body cells = rare case of intracellular ice nucleation Calcium phosphate spherules (Mugnano, 1996) Supercooling in Gall Flies ● Gall Fly larvae supercool their tissues using - polyols (sugar alcohols) ○ Sorbitol and Glycerol - primary cryoprotectants ● Lower freezing point -

Anastrepha Ludens
EPPO Datasheet: Anastrepha ludens Last updated: 2021-01-08 IDENTITY Preferred name: Anastrepha ludens Authority: (Loew) Taxonomic position: Animalia: Arthropoda: Hexapoda: Insecta: Diptera: Tephritidae Other scientific names: Acrotoxa ludens Loew, Anastrepha lathana Stone, Trypeta ludens (Loew) Common names: Mexican fruit fly view more common names online... EPPO Categorization: A1 list view more categorizations online... more photos... EU Categorization: A1 Quarantine pest (Annex II A) EPPO Code: ANSTLU Notes on taxonomy and nomenclature This species was first described in 1873 by Loew as Trypeta ludens. The current combination was proposed by Wulp (1900). The name Anastrepha lathana Stone is considered a synonym. Name, host plant, and distribution data for this species and other fruit flies are available under Fruit Fly Databases on the USDA Compendium of Fruit Fly Host Information. HOSTS Mango (Mangifera indica) and various species of Citrus, especially grapefruit and oranges, are the most important commercial hosts (Hernandez-Ortiz, 1992) of A. ludens. Peach (Prunus persica) and various other fruit crops are attacked less frequently, but more than 40 plant species are reported as at least occasional field hosts of this polyphagous pest (Norrbom, 2004). Thomas (2004) provides an example of A. ludens adaptive capability to infest new host plants, describing the discovery of the introduced manzano pepper (Capsicum pubescens) as an unexpected new host in Mexico. Nearly all of the commercial hosts of A. ludens are exotic. Baker et al. (1944) considered Casimiroa greggii (Rutaceae) to be the only native wild host, although three other Casimiroa spp. (Jirón et al., 1988) and several other wild native plants could also have been original hosts. -
Diccionario Campesino Hondureño Jeffery W. Bentley1 Prólogo Como
Diccionario campesino hondureño Jeffery W. Bentley1 Prólogo Los campesinos tienen un vocabulario enorme, del cual este diccionario documenta una parte. Los campesinos llevan una vida verbal, con poca influencia de medios visuales como el periódico, el cine y la televisión. Tienen un vocabulario grande, a pesar de que muchos de ellos no saben leer ni escribir. El conversar y escuchar la radio son fuentes importantes de información y diversión. En el campo se estima mucho una conversación con gracia. Mucha gente de la ciudad cree que los campesinos usan palabras inventadas por ellos mismos. Sin embargo, la mayoría son palabras antiguas, con raíces en idiomas viejos, como latín o náhuat. Los campesinos saben muchas palabras que los capitalinos no saben, pero que sí se encuentran en el Diccionario de la Lengua Española de la Real Academia. Sin embargo, el español rural hondureño es un idioma moderno, actualizado, que sigue cambiando para servir los intereses de un pueblo en cambio. Pretendemos aquí lograr tres metas. La primera es ayudar a la comunicación con el pueblo rural. En segundo, esperamos documentar en parte el mundo conceptual de la gente de las aldeas, mostrando que sus palabras son claves para conceptos complicados, profundos, con definiciones concretas. Las palabras muestran las categorías conceptuales de la gente. La tercera meta es que por medio de una presentación formal, brindar el prestigio y respeto que merece el hablar del pueblo rural de Honduras. Empecé a escribir el diccionario con un enfoque de dialecto: pensaba que los campesinos por ser un grupo social tenían su propio hablar. -
Papaya Fruit Fly, Toxotrypana Curvicauda Gerstaecker
EENY-021 Papaya Fruit Fly (suggested common name), Toxotrypana curvicauda Gerstaecker (Insecta: Diptera: Tephritidae)1 H. L. Selman, J. B. Heppner, and T. R. Fasulo2 Introduction Venezuela). In the United States, the fly is found in south- ern Texas and southern Florida. The papaya fruit fly, Toxotrypana curvicauda Gerstaecker, is the principal insect pest of papaya (Carica papaya L.) throughout the tropical and subtropical areas of the New World. The insect was introduced into Florida in 1905, most likely from the West Indies on papaya shipments. It first became established in the Florida Keys and Miami, then spread throughout the state wherever papayas are grown. Papaya fruit fly larvae and adults have been found in Florida in every month of the year. Although originally considered to be monophagous, infesting only wild and cultivated papaya, the insect has also been reported on mango and milkweed in Florida, and other plant species in Mexico.

Found in a single locality (Parszowice) in Lower Silesia, this species was recorded in a garden on Bryonia alba. Notes on the identification, biology and remarks on the general distribution and origin of the northern populations of this species are given. Colour photographs of the habitus and live specimens are also provided. Key words: Goniglossum wiedemanni, Carpomyini, species new for Poland, Lower Silesia, general distribution, Bryonia alba. INTRODUCTION Species from the family Tephritidae, the larvae of which develop in fruit, belong to the subfamilies Dacinae and Trypetinae. They occur most numerously in regions with a tropical or subtropical climate, where they pose a serious economic problem: in some areas they give rise to crop losses worth many millions of dollars. In central Europe, there are only a few species whose larvae feed on fruit; they belong exclusively to the tribes Carpomyini and Trypetini from the subfamily Trypetinae. -

Concluding Remarks Acknowledgments Glossary Bibliography Biographical Sketch Summary In this chapter we describe the current state of tropical insect chemical ecology in Latin America with the aim of stimulating the use of this important tool for future generations of technicians and professionals workers in insect pest management. Sex pheromones of tropical insectsUNESCO that have been identified to– date EOLSS are mainly used for detection and population monitoring. Another strategy termed mating disruption, has been used in the control of the tomato pinworm, Keiferia lycopersicella, and the Guatemalan potato moth, Tecia solanivora. Research into other semiochemicals such as kairomones in tropical insects SAMPLErevealed evidence of their presence CHAPTERS in coleopterans. However, additional studies are necessary in order to confirm these laboratory results. In fruit flies, the isolation of potential attractants (kairomone) from Spondias mombin for Anastrepha obliqua was reported recently. The use of semiochemicals to control insect pests is advantageous in that it is safe for humans and the environment. The extensive use of these kinds of technologies could be very important in reducing the use of pesticides with the consequent reduction in the level of contamination caused by these products around the world. -

Pondero que depois de um esclarecedor início de século, durante o qual muitas descobertas significativas foram feitas sobre a história natural desses insetos, pouco progresso tem sido observado em muitas áreas de pesquisas e manejo de moscas-das-frutas na América Latina durante os últimos 50 anos. Isso tem sido causado em parte pela escassez de estudos sob condições naturais, bem com pela abordagem reducionista utilizada no estudo desses insetos maravilhosos, considerando as espécies individualmente, ou apenas as espécies-praga. Para interromper esse círculo vicioso, proponho que demos mais atenção à história natural das espécies, independente de sua importância econômica, ampliemos o escopo e o período de tempo de nossos estudos, fortaleçamos os fundamentos teóricos e ecológicos das pesquisas com moscas-das-frutas na América Latina e enfatizemos o enfoque comparativo sempre que possível. -
Flies) Benjamin Kongyeli Badii
Chapter Phylogeny and Functional Morphology of Diptera (Flies) Benjamin Kongyeli Badii Abstract The order Diptera includes all true flies. Members of this order are the most ecologically diverse and probably have a greater economic impact on humans than any other group of insects. The application of explicit methods of phylogenetic and morphological analysis has revealed weaknesses in the traditional classification of dipteran insects, but little progress has been made to achieve a robust, stable clas- sification that reflects evolutionary relationships and morphological adaptations for a more precise understanding of their developmental biology and behavioral ecol- ogy. The current status of Diptera phylogenetics is reviewed in this chapter. Also, key aspects of the morphology of the different life stages of the flies, particularly characters useful for taxonomic purposes and for an understanding of the group’s biology have been described with an emphasis on newer contributions and progress in understanding this important group of insects. Keywords: Tephritoidea, Diptera flies, Nematocera, Brachycera metamorphosis, larva 1. Introduction Phylogeny refers to the evolutionary history of a taxonomic group of organisms. Phylogeny is essential in understanding the biodiversity, genetics, evolution, and ecology among groups of organisms [1, 2]. Functional morphology involves the study of the relationships between the structure of an organism and the function of the various parts of an organism. The old adage “form follows function” is a guiding principle of functional morphology. It helps in understanding the ways in which body structures can be used to produce a wide variety of different behaviors, including moving, feeding, fighting, and reproducing. It thus, integrates concepts from physiology, evolution, anatomy and development, and synthesizes the diverse ways that biological and physical factors interact in the lives of organisms [3].
