Protein, fat, ash and mineral content were determined for the preprocessed, well prepared and spoiled bugs. The proximate composition and minerals of the insects were determined using standard methods. One Way Analysis of Variance (ANOVA) was used in analyzing data. They were found to contain 30-36% protein; 51-53% fat and 1-1.5% ash respectively. Spoiled bugs contained the lowest protein content of 30.76±0.98% and highest amount of magnesium of 120±2.2 mg/100g while the preprocessed and well processed contained 110±2.5 mg/100g and 112±2.4 mg/100g respectively. Phosphorous was the most abundant in all forms with a value of 570-575 mg/100g. Calcium levels for all the three forms showed an overall mean of 85-89 mg/100g. -

Abstract This study investigated the consumption of ed ible insects in Nxaraga, Sehithwa and Shorobe villages of the North West district of Botswana. Information was gathered using a structured questionnaire which was administered to 60 respondents across the three villages and also through direct observation. A total of six insect species were identified belonging to six families and four orders (i.e., Coleoptera, Isoptera, Lepidoptera and Orthoptera) with t he two most consumed orders being Lepidoptera and Coleoptera. Carebara vidua F. Smith (33.3%) was the most consumed followed by Sternocera orissa Buq. (21.7%), Agrius convolvuli L. (15.0%), Oryctes boas Fabr.(13.3%), Imbrasia belina Westwood (10.0%) and Lo custa migratoria (6.7%). The study revealed that insects were abundant during and/or immediately after the rainy season. This implies that insects can be harvested and preserved during the time of abundan ce to maximize their utilization in meeting the human protein needs. The common methods of collecting insects were hand picking, trapping and digging. Insects were prepared for consumption by boiling, frying or roasting. -

Chapter 15. Central and Eastern Africa: Overview
Chapter 15 Chapter 15 CENTRAL AND EASTERN AFRICA: OVERVIEW The region as treated here is comprised mainly of Angola, Cameroon, Central African Republic, Congo (Brazzaville), Congo (Kinshasa) (formerly Zaire), Kenya, Malawi, Tanzania, Uganda, and Zambia. The wide variety of insects eaten includes at least 163 species, 121 genera, 34 families and 10 orders. Of this group the specific identity is known for 128 species, only the generic identity for another 21, only the family identity of another 12 and only the order identity of one. Gomez et al (1961) estimated that insects furnished 10% of the animal proteins produced annually in Congo (Kinshasa). Yet, in this region, as in others, insect use has been greatly under-reported and under-studied. Until recently, for example, the specific identity was known for fewer than twenty species of insects used in Congo (Kinshasa), but, in a careful study confined only to caterpillars and only to the southern part of the country, Malaisse and Parent (1980) distinguished 35 species of caterpillars used as food. The extent of insect use throughout the region is probably similar to that in Congo (Kinshasa) and Zambia, the best-studied countries. Research is needed. Caterpillars and termites are the most widely marketed insects in the region, but many others are also important from the food standpoint, nutritionally, economically or ecologically. As stated by this author (DeFoliart 1989): "One can't help but wonder what the ecological and nutritional maps of Africa might look like today if more effort had been directed toward developing some of these caterpillar, termite, and other food insect resources." The inclusion of food insects in the Africa-wide Exhibition on Indigenous Food Technologies held in Nairobi, Kenya, in 1995 is indicative of the resurgence of interest in this resource by the scientific community of the continent. -
Insects for Human Consumption
Chapter 18 Insects for Human Consumption Marianne Shockley1 and Aaron T. Dossey2 1Department of Entomology, University of Georgia, Athens, GA, USA, 2All Things Bugs, Gainesville, FL, USA 18.1. INTRODUCTION The utilization of insects as a sustainable and secure source of animal-based food for the human diet has continued to increase in popularity in recent years (Ash et al., 2010; Crabbe, 2012; Dossey, 2013; Dzamba, 2010; FAO, 2008; Gahukar, 2011; Katayama et al., 2008; Nonaka, 2009; Premalatha et al., 2011; Ramos- Elorduy, 2009; Smith, 2012; Srivastava et al., 2009; van Huis, 2013; van Huis et al., 2013; Vantomme et al., 2012; Vogel, 2010; Yen, 2009a, b). Throughout the world, a large portion of the human population consumes insects as a regular part of their diet (Fig. 18.1). Thousands of edible species have been identified (Bukkens, 1997; Bukkens and Paoletti, 2005; DeFoliart, 1999; Ramos-Elorduy, 2009). However, in regions of the world where Western cultures dominate, such as North America and Europe, and in developing countries heavily influenced by Western culture, mass media have negatively influenced the public’s percep- tion of insects by creating or reinforcing fears and phobias (Kellert, 1993; Looy and Wood, 2006). Nonetheless, the potentially substantial benefits of farming and utilizing insects as a primary dietary component, particularly to supplement or replace foods and food ingredients made from vertebrate livestock, are gain- ing increased attention even in Europe and the United States. Thus, we present this chapter to -

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 Mcguire Center for Lepidoptera and Biodiversity
Supplemental Information All specimens used within this study are housed in: the McGuire Center for Lepidoptera and Biodiversity (MGCL) at the Florida Museum of Natural History, Gainesville, USA (FLMNH); the University of Maryland, College Park, USA (UMD); the Muséum national d’Histoire naturelle in Paris, France (MNHN); and the Australian National Insect Collection in Canberra, Australia (ANIC). Methods DNA extraction protocol of dried museum specimens (detailed instructions) Prior to tissue sampling, dried (pinned or papered) specimens were assigned MGCL barcodes, photographed, and their labels digitized. Abdomens were then removed using sterile forceps, cleaned with 100% ethanol between each sample, and the remaining specimens were returned to their respective trays within the MGCL collections. Abdomens were placed in 1.5 mL microcentrifuge tubes with the apex of the abdomen in the conical end of the tube. For larger abdomens, 5 mL microcentrifuge tubes or larger were utilized. A solution of proteinase K (Qiagen Cat #19133) and genomic lysis buffer (OmniPrep Genomic DNA Extraction Kit) in a 1:50 ratio was added to each abdomen containing tube, sufficient to cover the abdomen (typically either 300 µL or 500 µL) - similar to the concept used in Hundsdoerfer & Kitching (1). Ratios of 1:10 and 1:25 were utilized for low quality or rare specimens. Low quality specimens were defined as having little visible tissue inside of the abdomen, mold/fungi growth, or smell of bacterial decay. Samples were incubated overnight (12-18 hours) in a dry air oven at 56°C. Importantly, we also adjusted the ratio depending on the tissue type, i.e., increasing the ratio for particularly large or egg-containing abdomens. -
