How Cultural Perceptions and Food Preparation Affect Westerners View of Insects as Food

There has been a recent push to encourage westerners to introduce insects into their diets. Traditional arguments that stress environmental and nutritional benefits have been largely unsuccessful. This not because people simply find insects distasteful; what people view as an acceptable food choice is culturally dependent, and foods made from novel and unfamiliar ingredients or tools are met with apprehension. What is less known is why insects are viewed as an unacceptable food source in western society. It has been suggested that westerners disgust towards insects is that insects are perceived of as contaminants and as vectors of disease. If westerners are unwilling to eat insects, or food prepared with insects because they are viewed as unhygienic, then we should expect individuals who are less concerned with hygiene to be more willing to eat insects, or food prepared with insects. When surveyed on their hygiene and their willingness to try food prepared using insects, participants that were less concerned with personal hygiene were more willing to eat food made with insects. In order to convince people to introduce insects into their diet one must know why people are so uneager to consume insects

Why are Americans against eating insects?

Some scientists are worried about food shortages in the future as the population grows, and food production is not growing fast enough to keep up (Tao and Li 2018). This has led many scientists to look at insects as potential replacements or supplements to current livestock because insects are much more efficient, cheap, and environmentally friendly to raise than traditional live stock and have more protein per mass (Hartmann and Siegrist 2017). However, the trouble is to get Americans and other Westerners to accept insects into their diet because they are the largest consumers of meat in the world, and to be able to do that we need to understand the Western aversion to eating insects. (Schuursman 2014) According to my research, the most likely factors that cause United States citizens to have an aversion to eating insects are because they see insects as pests to their crops, because insects look alien and scary to them, and, or because eating insects is not convenient, cheap, or socially accepted (Bellisle 2006). My study showed that there is a positive relationship between interest in trying insects and likelihood of buying them from the store, between not seeing insects as a pest and interest in trying insects, someone’s adventurousness and their openness to trying new foods, and the likelihood of eating insects if it was socially accepted and interest in trying insects. My results are important because they show that there are several identifiable factors that determine whether or not someone is interested in trying insects. This shows that by meeting these factors, we can get Westerners to at the very least try insects

Factors Affecting Capture Rates of Insect Taxa by Retail Electrocutors and Eliminators in Northern Lower Michigan

We compare the abundance and types of insects captured at several locations, with and without a chemical attractant and in varying weather conditions using two different devices advertised to kill biting insects. Using both an insect electrocutor that uses ultraviolet light as an attractant, with and without octenol as an added attractant, and an insect eliminator that uses carbon dioxide, heat and octenol as attractants, more non-biting than biting insects were captured. Numerous harmless and beneficial insects were killed with electrocutors. Although eliminators were more target-specific, they captured fewer insects overall compared to electrocutors. The numbers and types of insects captured also varied by location and temperature conditions. More insects were killed by electrocutors located next to a lake compared to those located in an inland forested area and more were killed at lower compared to higher heights above the ground. More insects were also killed by electrocutors on warmer than on cooler nights. More non-biting insects were killed with electrocutors baited with octenol than without octenol

Who's the pest? Imagining human–insect futures beyond antagonism

Joining the effort to reimagine our relationships with insects, the Wellcome Collection's ‘Who's the Pest?’ programme attempts to challenge the stigma of insects as ill-disposed ‘bugs’. The article reviews two events in the series, the workshop ‘Insects au gratin’ and the debate ‘Insects vs. humans’, and places them in the context of recent engagements with ‘pests’ in the public realm

January Collecting in Central Michigan

Excerpt: To the uninitiated reader, searching for adult insects in mid-winter might seem a fruitless task at best. Yet as the List of Michigan Insects and Related Arthropods takes shape, L\u27off-season collecting records are urgently needed by the compilers. Many species of insects thrive when we might wish to stay indoors; the Collembola are good examples, as are the species of Chionea (Diptera: Tipulidae), a genus of wingless crane-flies. We should like to know much more about the distribution of many hardy winter insects, and only increased collecting will enable this

Metapopulation Patterns of Iberian Butterflies Revealed by Fuzzy Logic

Metapopulation theory considers that the populations of many species are fragmented into patches connected by the migration of individuals through an interterritorial matrix. We applied fuzzy set theory and environmental favorability (F) functions to reveal the metapopulational structure of the 222 butterfly species in the Iberian Peninsula. We used the sets of contiguous grid cells with high favorability (F ≥ 0.8), to identify the favorable patches for each species. We superimposed the known occurrence data to reveal the occupied and empty favorable patches, as unoccupied patches are functional in a metapopulation dynamics analysis. We analyzed the connectivity between patches of each metapopulation by focusing on the territory of intermediate and low favorability for the species (F < 0.8). The friction that each cell opposes to the passage of individuals was computed as 1‐F. We used the r.cost function of QGIS to calculate the cost of reaching each cell from a favorable patch. The inverse of the cost was computed as connectivity. Only 126 species can be considered to have a metapopulation structure. These metapopulation structures are part of the dark biodiversity of butterflies because their identification is not evident from the observation of the occurrence data but was revealed using favorability functionsFunding for open access charge: Universidad de Málaga / CBU

Darkling beetles (Alphitobius diaperinus) and their larvae as potential vectors for the transfer of Campylobacter jejuni and Salmonella enterica serovar paratyphi B variant Java between successive broiler flocks

Broiler flocks often become infected with Campylobacter and Salmonella, and the exact contamination routes are still not fully understood. Insects like darkling beetles and their larvae may play a role in transfer of the pathogens between consecutive cycles. In this study, several groups of beetles and their larvae were artificially contaminated with a mixture of Salmonella enterica serovar Paratyphi B Variant Java and three C. jejuni strains and kept for different time intervals before they were fed to individually housed chicks. Most inoculated insects were positive for Salmonella and Campylobacter just before they were fed to the chicks. However, Campylobacter could not be isolated from insects that were kept for 1 week before they were used to mimic an empty week between rearing cycles. All broilers fed insects that were inoculated with pathogens on the day of feeding showed colonization with Campylobacter and Salmonella at levels of 50 to 100%. Transfer of both pathogens by groups of insects that were kept for 1 week before feeding to the chicks was also observed, but at lower levels. Naturally contaminated insects that were collected at a commercial broiler farm colonized broilers at low levels as well. In conclusion, the fact that Salmonella and Campylobacter can be transmitted via beetles and their larvae to flocks in successive rearing cycles indicates that there should be intensive control programs for exclusion of these insects from broiler houses

Abundance of Insects Inhabiting the Male Strobili of Red Pine

(excerpt) Southwood (1973) concluded that pollen feeding was probably the first step in the development of the phytophagous habit in insects, because pollen, compared with plant foliage, is rich in nutrients and low in sewndary defense substances. Surprisingly, little is known about insects that feed mainly on pollen. For example, in a bibliography of insects that feed on reproductive structures of North American conifers (Barcia and Merkel, 1972), less than three per cent of 719 references pertained to pollen feeders. This note reports on the kinds and abundance of insects found inhabiting clusters of fresh staminate or male strobili (MS) of 60- to 65-year-old red pine trees in two seed production areas (SPAs) in northern Minnesota
