Edible insect consumption called entomophagy is very important in ensuring food security especially in a developing country like Nigeria, but promotion of entomophagy after a long period of adoption of western diets demands a comprehensive inventory of edible insect consumption in the past. At present, there is little or no repository of document with comprehensive information on edible insects consumed in the south eastern states of Nigeria and methods of use is also scarce in literature. It becomes imperative to assess edible insect consumption in the region as a background for promotion of entomophagy in the area. The study used questionnaires and oral interviews to obtain information on types of edible insects consumed, season of harvest, cooking methods, local dishes with edible insects, people’s reaction to edible insect consumption, challenges of entomophagy business and ethno-cultural beliefs on edible insect consumption. Of the 2,000 individuals sampled, 56.4% were males, 43.6% females, with 22.4% children, 19.6% teenagers, 24.2% young adults, 16.6% older adults and 17.2% aged above 60 years of age. The result showed that seventeen insect species belonging to six orders were consumed and harvesting is mainly during the rains, though some recorded year round availability. Restricted seasonal availability and high collecting costs are among the reported barriers to edible insect consumption The most common cooking methods documented in the study were frying or roasting. Six traditional dishes were found to include edible insects. Four ethno-cultural beliefs on some edible insects were also documented. Edible insect farming is therefore recommended as a strategy to bridge the gap between insect protein supply and demand in the region.

Edible insects present unique opportunities for food and nutrition security in many African communities. However, the characteristics of habitats and spatial distribution of edible insects is not known and yet it is important for understanding their ecology, planning harvesting and conservation activities in the wild. The edible ground cricket (Henicus whellani) Chopard (Orthoptera: Stenopelmatidae) is an edible insect consumed in south eastern Zimbabwe with protein content >50% on dry matter basis but harvesting is largely random and opportunistic. The aim of this study was to apply the Maximum Entropy (MaxEnt) presence-only species distribution modelling approach to understand the factors influencing distribution of H. whellani and map the potential areas for harvesting and conservation of the species. Geographical locations of sites where H. whellani is currently present were obtained from field reports from communities. Seven geographical factors which are mean annual temperature, temperature seasonality, mean annual precipitation, seasonality of precipitation, soil type, elevation, vegetation density and land cover were used to run the model. The model showed a high prediction accuracy for H. whellani (AUC=0.86) indicating that the model can be used with confidence to predict distribution and potential habitats in S.E Zimbabwe. Results showed that soil type (46.7%) and vegetation density (17.5%) are the most important factors determining the distribution of H. whellani. The hotspots for H. whellani were identified and closely followed specific soil and vegetation gradients in the area. The model considered temperature (3.9%) and elevation (0.6%) as the least important factors in H. whellani distribution. The produced distributed maps can be used for planning efficient harvesting and conservation of this nutritious edible insect in Zimbabwe.

This paper examines current literature on edible insect consumption in western culture through an inductive lens, addressing environmental, nutritional, food security, anthropological and psychological aspects of the topic. Findings show that western aversion towards edible insects is deeply psychological and cultural, mostly ignoring the pleasure dimensions such as taste, texture and flavour. The nature of the problem appears to be predominantly social. Results suggest that a beneficial route of introducing edible insects into the western diet could be formed through a societal perspective. Tourism and hospitality can potentially play a big part in the edible insect development. For instance, food as a tourism product can attract visitors from different backgrounds whilst food consumption as a tourism experience subliminally promises an experience of novelty and potential newfound pleasure in food. Food as an integral part of various cultures and local heritages entails local dishes that can be considered ‘cultural artifacts’ and their consumption symbolises the consumption of ‘other’. Tourism experiences can expose an individual to lasting personal change, self-discovery and intellectual development. Hence, taking into consideration that acquiring new cultural knowledge increases openness to experience, it is possible that tourism could contribute to adopting the practice of insect consumption in the western cultural sphere.

Edible insects are important sources of nutrition, particularly in Africa, Asia, and Latin America. Recently, edible insects have gained considerable interest as a possible solution to global exhaustion of the food supply with population growth. However, little attention has been given to the adverse reactions caused by insect consumption. Here, we provide an overview of the food allergens in edible insects and offer insights for further studies. Most of the edible insect allergens identified to date are highly cross-reactive invertebrate pan-allergens such as tropomyosin and arginine kinase. Allergic reactions to these allergens may be cross-reactions resulting from sensitization to shellfish and/or house dust mites. No unique insect allergen specifically eliciting a food allergy has been described. Many of the edible insect allergens described thus far have counterpart allergens in cockroaches, which are an important cause of respiratory allergies, but it is questionable whether inhalant allergens can cause food allergies. Greater effort is needed to characterize the allergens that are unique to edible insects so that safe edible insects can be developed. The changes in insect proteins upon food processing or cooking should also be examined to enhance our understanding of edible insect food allergies.

Abstract Although research has demonstrated the positive nutritional value and environmental benefits associated with edible insect consumption, several factors challenge the growth and development of the edible insect industry for human consumption in the US and Canada. Cultural and psychological factors account for much of the aversion US and Canadian consumers display. The absence of specific regulation also constitutes a structural barrier to more widespread production and sale of edible insects. Compared to the US, the European Union has a more developed edible insect industry and has enacted legislation that removes some of the barriers. As consumer awareness of the putative health benefits of edible insects increases, more comprehensive regulations may emerge to keep pace with the growth of this industry. Overall, a multi-disciplinary approach that addresses both benefits and barriers to consumption is needed to facilitate a robust market for edible insects in the US and Canada.

All over the world, a large proportion of the population consume insects as part of their diet. In Western countries, however, the consumption of insects is perceived as a negative phenomenon. The consumption of insects worldwide can be considered in two ways: on the one hand, as a source of protein in countries affected by hunger, while, on the other, as an alternative protein in highly-developed regions, in response to the need for implementing policies of sustainable development. This review focused on both the regulations concerning the production and marketing of insects in Europe and the characteristics of edible insects that are most likely to establish a presence on the European market. The paper indicates numerous advantages of the consumption of insects, not only as a valuable source of protein but also as a raw material rich in valuable fatty acids, vitamins, and mineral salts. Attention was paid to the functional properties of proteins derived from insects, and to the possibility for using them in the production of functional food. The study also addresses the hazards which undoubtedly contribute to the mistrust and lowered acceptance of European consumers and points to the potential gaps in the knowledge concerning the breeding conditions, raw material processing and health safety. This set of analyzed data allows us to look optimistically at the possibilities for the development of edible insect-based foods, particularly in Europe.

Abstract Why do modern states recruit legionnaires—foreigners who are neither citizens nor subjects of the country whose military they serve? Rather than exclusively enlist citizens for soldiers, for the past two centuries states have mobilized legionnaires to help wage offensives, project power abroad, and suppress dissent. A supply-and-demand argument explains why states recruit these troops, framing the choice to mobilize legionnaires as a function of political factors that constrain the government's leeway to recruit domestically and its perceptions about the territorial threats it faces externally. A multimethod approach evaluates these claims, first by examining an original dataset of legionnaire recruitment from 1815 to 2020, then by employing congruence tests across World War II participants, and finally by conducting a detailed review of a hard test case for the argument—Nazi Germany. The prevalence of states’ recruitment of legionnaires calls for a reevaluation of existing narratives about the development of modern militaries and provides new insights into how states balance among the competing imperatives of identity, norms, and security. Legionnaire recruitment also underscores the need to recalibrate existing methods of calculating net assessments and preparing for strategic surprise. Far from being bound to a state's citizenry or borders, the theory and evidence show how governments use legionnaires to buttress their military power and to engineer rapid changes in the quality and quantity of the soldiers that they field.

Dr. Feldstein has produced an essay of extraordinary clarity for the lay reader. He bravely tackles the incredibly complex issue of hospital economics. He analyzes the course of hospital cost inflation during the past 20 years and attempts to define the underlying causes. Unlike many economists he does not fall into the trap of comparing hospitals with other industries nor does he try to apply the simplistic laws of supply and demand as they apply to the manufacturer of goods.

Ancient Times

The custom and culture of entomophagy in China has been preserved since ancient times, with a history going back at least 3,000 years. Presently, more than 300 species of insects with edible value have been taxonomically classified in China. These insect species belong to the orders Lepidoptera, Coleoptera, Hymenoptera, Orthoptera, Hemiptera, Isoptera, Odonata, Megaloptera, Ephemeroptera, Diptera and Blattaria, with a majority of these species belonging to Lepidoptera, Coleoptera and Hymenoptera. The most common include silkworm, tussah, Italian honeybee, oriental honeybee, mealworm, wasps, bamboo worm, locust, cicada, diving beetle and black ant. Since 2010, the number of patent applications for these edible insects has increased rapidly, indicating that the development and utilisation of edible insects in China is ongoing. The use of common edible insects primarily involves direct consumption of the insect body. In addition to fresh insects, frozen, canned and dried insects are also sold on the market. Derived extract products, such as protein, oil, chitin and insect health foods remain in the early research and experiment stages, and the current production scale is small. Bees, silkworm, mealworm and oriental migratory locust come from artificial farming, as farming techniques for these insects are well-developed. Although wasps, sand-crawling insects, bean hawkmoths and bamboo worms have been artificially cultured, the necessary technologies are underdeveloped. The majority of edible insects generally accepted by the public are still primarily collected from nature. In view of the current situation of utilisation, some suggestions have been put forward to strengthen the investigation and evaluation of edible insect resources, and research to focus on utilisation methods and artificial rearing technology in China.
