Sex-Linked Transcription Factor Involved in a Shift of Sex-Pheromone Preference in the Silkmoth Bombyx Mori

What Do Insects Do for a Living?
4/19/15 What do insects do for a living? Insect Ecology Ground-dwelling: Where are they found and what are they doing? Common habits • Detritivores and saprophages • Rhizophagous insects • Predators and ground-nesting insects • Decaying wood • Coprophages • Necrophages • Fungivores 1 4/19/15 Predators & Ground-nesters Decaying Wood • Usually associated with fungi – What else is there? • Numerous taxa – Wood wasps, bark beetles, ambrosia beetles, scavenger beetles, silken fungus beetles, dance flies, termites, cockroaches. Associations with fungi • Most have specialized Sirex wood wasp structures for carrying fungal spores: mycangia. • Why are most attracted to forest fires?: pyrophilous. 2 4/19/15 Coprophages • What are these? • What are they feeding on? • Why is this such a good lifestyle? • First colonization usually dung flies. • ~45 independent origins of viviparity. Why? Coprophages • These can get to nuisance levels. • Dung dispersers therefore provide an important ecosystem service. • Almost always Scarabaeidae 3 4/19/15 Necrophages • Often a very similar lifestyle to coprophages. • Often very closely related. • Most other origins of viviparity here. Necrophages • Often distinct succession. • Very useful for forensic entomology. • Most initial colonizers are Diptera. • Later are Coleoptera (e.g. Silphidae). • Dried are more Coleoptera (e.g. Dermestidae) • Final stages are tineid larvae (keratin) Fungivores • The true decomposers are fungi. • There is a whole guild of insects that specialize on these. 4 4/19/15 Aquatic Insects • Insecta (even Hexapoda) are plesiomorphically terrestrial. • But there have been numerous colonizations of the freshwater aquatic environment. • Far fewer colonizations of marine aquatic environment. Hemimetabolous Aquatic Insects • Some lineages have almost* exclusively aquatic naiads. – Ephemeroptera – Odonata* – Plecoptera (the only aquatic Polyneoptera) • All of these have terrestrial adults. -
The Beetles Story
NATURE The Beetles story They outshine butterflies and moths in the world of insects and are a delight for their sheer variety—from the brilliantly coloured to the abysmally dull. But they have their uses, too, such as in museums, where flesh-eating beetles are used to clean off skeletons. Text & photographs by GEETHA IYER THE GIRAFFE WEEVIL (Cycnotrachelus flavotuberosus). Weevils are a type of beetle and they are a menace to crops. 67 FRONTLINE . MARCH 31, 2017 HOW was this watery planet we so much love born? Was it created by God or born off the Big Bang? While arguments swing between science and religion, several ancient cultures had different and interesting per- spectives on how the earth came to be. Their ideas about this planet stemmed from their observations of nature. People living in close prox- imity to nature develop a certain sen- sitivity towards living creatures. They have to protect themselves from many of these creatures and at the same time conserve the very envi- ronment that nurtures them. So there is constant observation and in- teraction with nature’s denizens, es- pecially insects, the most proliferate among all animal groups that stalk every step of their lives. The logic for creation thus revolves around differ- ent types of insects, especially the most abundant amongst them: bee- WATER BEETLE.

In recent years there have been numerous studies focused on the anticancer action of cantharidin and its derivatives. Despite the recent interest in blister beetles, cytogenetic and molecular studies in this group are scarce and most of them use only classical chromosome staining techniques. The main aim of our study was to provide new information in Citation: Ruiz-Torres, L.; Mora, P.; Meloidae. In this study, cytogenetic and molecular analyses were applied for the first time in the Ruiz-Mena, A.; Vela, J.; Mancebo, F.J.; family Meloidae. We applied fluorescence staining with DAPI and the position of ribosomal DNA in Montiel, E.E.; Palomeque, T.; Lorite, P. Hycleus scutellatus was mapped by FISH.

Oral Presentations
ORAL PRESENTATIONS Listed in programme order Technical analysis of archaeological Andean painted textiles Rebecca Summerour1*, Jennifer Giaccai2, Keats Webb3, Chika Mori2, Nicole Little3 1National Museum of the American Indian, Smithsonian Institution (NMAI) 2Freer Gallery of Art and Arthur M. Sackler Gallery, Smithsonian Institution (FSG) 3Museum Conservation Institute, Smithsonian Institution (MCI) 1*[email protected] This project investigates materials and manufacturing techniques used to create twenty-one archaeological painted Andean textiles in the collection of the National Museum of the American Indian, Smithsonian Institution (NMAI). The textiles are attributed to Peru but have minimal provenience. Research and consultations with Andean textile scholars helped identify the cultural attributions for most of the textiles as Chancay and Chimu Capac or Ancón. Characterization of the colorants in these textiles is revealing previously undocumented materials and artistic processes used by ancient Andean textile artists. The project is conducted as part of an Andrew W. Mellon Postgraduate Fellowship in Textile Conservation at the NMAI. The textiles in the study are plain-woven cotton fabrics with colorants applied to one side. The colorants, which include pinks, reds, oranges, browns, blues, and black, appear to be paints that were applied in a paste form, distinguishing them from immersion dyes. The paints are embedded in the fibers on one side of the fabrics and most appear matte, suggesting they contain minimal or no binder. Some of the brown colors, most prominent as outlines in the Chancay-style fragments, appear thick and shiny in some areas. It is possible that these lines are a resist material used to prevent colorants from bleeding into adjacent design elements. -
State-Of-The-Art on Use of Insects As Animal Feed
State-of-the-art on use of insects as animal feed Harinder P.S. Makkar1, Gilles Tran2, Valérie Heuzé2 and Philippe Ankers1 1 Animal Production and Health Division, FAO, Rome 2 Association Française de Zootechnie, Paris, France Full reference of the paper: Animal Feed Science and Technology, Volume 197, November 2014, pages 1-33 Link: http://www.animalfeedscience.com/article/S0377-8401(14)00232-6/abstract http://dx.doi.org/10.1016/j.anifeedsci.2014.07.008 Abstract A 60-70% increase in consumption of animal products is expected by 2050. This increase in the consumption will demand enormous resources, the feed being the most challenging because of the limited availability of natural resources, ongoing climatic changes and food-feed-fuel competition. The costs of conventional feed resources such as soymeal and fishmeal are very high and moreover their availability in the future will be limited. Insect rearing could be a part of the solutions. Although some studies have been conducted on evaluation of insects, insect larvae or insect meals as an ingredient in the diets of some animal species, this field is in infancy. Here we collate, synthesize and discuss the available information on five major insect species studied with respect to evaluation of their products as animal feed. The nutritional quality of black soldier fly larvae, the house fly maggots, mealworm, locusts- grasshoppers-crickets, and silkworm meal and their use as a replacement of soymeal and fishmeal in the diets of poultry, pigs, fish species and ruminants are discussed. The crude protein contents of these alternate resources are high: 42 to 63% and so are the lipid contents (up to 36% oil), which could possibly be extracted and used for various applications including biodiesel production. -

The Importance of Ecological Memory for Trophic Rewilding As an Ecosystem Restoration Approach

However, the suitability of novel restoration concepts such as trophic rewilding is still under discussion given fragmentary empirical data and limited theory development. Here, we develop a theoretical framework that integrates the concept of ‘ecological memory’ into trophic rewilding. The ecological memory of an ecosystem is defined as an ecosystem’s accumulated abiotic and biotic material and information legacies from past dynamics. By summarising existing knowledge about the ecological effects of megafauna extinction and rewilding across a large range of spatial and temporal scales, we identify two key drivers of ecosystem responses to trophic rewilding: (i) impact potential of (re)introduced megafauna, and (ii) ecological memory characterising the focal ecosystem. The impact potential of (re)introduced megafauna species can be estimated from species properties such as lifetime per capita engineering capacity, population density, home range size and niche overlap with resident species. -
