ARTHROPODA Subphylum Hexapoda Protura, Springtails, Diplura, and Insects

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000). -
Abundance of Mycophagous Arthropods Present on Different Species of Fungi in Relation to Resource Abundance at Different Spatial Scales

Host selection, fungi, fungus-visiting arthropods, spatial scale Abstract. The abundance of Coleoptera, Diptera and Collembola on different species of fungi was investigated in relation to the size and abundance of fungal resources at different spatial scales; i.e., the size of the fungal fruiting body, the quality of resource in terms of number of conspecific sporophores growing within a radius of 50 cm, crowding of the clumps of fruiting bodies, and the quality of resource within a plot (20 m × 30 m). Multiple linear regression analyses showed that the influential spatial scale varied among the arthropod orders. The amount of resource at the scale of a clump made a significant contribution to the abundance of Coleoptera, and the fruiting body size significantly affected the abundance of Diptera on each fungal species. Collembolan abundance was sig- nificantly affected by the crowding of the clumps of fruiting bodies and the number of fruiting bodies per plot. These results suggest that the spatial distribution of fungal fruiting bodies may determine whether they are selected by arthropods visited.

Drosophila Suzukii

For current information, see the OSU Extension Catalog: https://catalog.extension.oregonstate.edu/em9026 Protecting Garden Fruits from Spotted Wing Drosophila Drosophila suzukii EM 9026 • April 2011 potted wing drosophila (Drosophila suzukii; SWD) is a new, invasive pest that attacks stone Sfruits and berries. This pest is native to Japan, where the first reports of this “vinegar fly” date to 1916, and has been established in Hawaii since the early 1980s, although no noticeable damage has been reported there. On the mainland United States, SWD was first discovered in the fall of 2008, maturing on raspberry and strawberry fruits in California. In 2009, SWD was reported in Oregon, Washington, Florida, and British Columbia, Canada. In 2010, SWD flies were caught in monitoring traps in Figure 1. Following the 2009 and 2010 growing seasons, Michigan, Utah, North Carolina, South Carolina, and spotted wing drosophila was known to be present in Benton, Clackamas, Columbia, Douglas, Hood River, Louisiana. In 2011, SWD was reported for the first Jackson, Josephine, Lane, Linn, Lincoln, Marion, time in Baja, Mexico. Multnomah, Polk, Wasco, Washington, Umatilla, and In Oregon, SWD has been confirmed in 17 coun- Yamhill counties. SWD presence was confirmed by ties (figure 1).

Given the rapid spread of SWD in Oregon and across the United States, it is reasonable to suspect that SWD is widespread, well established, and most likely present in additional counties and states. -

Abstract: The fruit fly, Drosophila melanogaster, has been used to understand fundamental principles of genetics and biology for over a century. Drosophila is now also considered an essential tool to study mechanisms underlying numerous human genetic diseases. In this review, we will discuss how flies can be used to deepen our knowledge of infectious disease mechanisms in vivo. Flies make effective and applicable models for studying host-pathogen interactions thanks to their highly con- served innate immune systems and cellular processes commonly hijacked by pathogens. Drosophila researchers also possess the most powerful, rapid, and versatile tools for genetic manipulation in multicellular organisms. This allows for robust experiments in which specific pathogenic proteins can be expressed either one at a time or in conjunction with each other to dissect the molecular functions of each virulent factor in a cell-type-specific manner. -

ABSTRACT Genome size varies across the tree of life, with no clear correlation to organismal complexity or KEYWORDS coding sequence, but with differences in non-coding regions. Phylogenetic methods have recently been Genome size incorporated to further disentangle this enigma, yet most of these studies have focused on widely diverged sex chromosome species. Few have compared patterns of genome size change in closely related species with known Drosophila structural differences in the genome. As a consequence, the relationship between genome size and phylogenetic differences in chromosome number or inter-sexual differences attributed to XY systems are largely comparative unstudied. We hypothesize that structural differences associated with chromosome number and X-Y methods chromosome differentiation, should result in differing rates and patterns of genome size change. In this study, we utilize the subgenera within the Drosophila to ask if patterns and rates of genome size change differ between closely related species with differences in chromosome numbers and states of the XY system. Genome sizes for males and females of 152 species are used to answer these questions (with 92 newly added or updated estimates). -

His parents, though not poor, were not wealthy either. They ran a small shop in Solingen. His paternal grandparents however owned an estate and hamlet with twenty houses. Adding to the rental income, Meigen’s grandfather was a farmer and a guild mastercutler in Solingen. Two years after Meigen was born his grandparents died and his parents moved to the family estate. This was already heavily indebted by the Seven Years' War, then bad crops and rash speculations forced sale and the family moved back to Solingen. Meigen attended the town school but only for a short time. Fortunately he had learned to read and write on his grandfather’s estate and he read widely at home as well as taking an interest in natural history. -
