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.

Total Body

In larval and pupal stages of several insect species the changes in total body metabolism appear to be inversely proportional to the course of ecdysteroid titres. The largest peaks of ecdysteroid occur exactly at the time of the lowest metabolic rates. These relationships are consequences of the developmental programming; ecdysteroid has no direct antimetabolic action. The problem of ecdysteroid-metabolic interactions has been discussed in relation to possible homeostatic function of ecdysteroids in insect development.

Target Sites

Calcium (Ca2+) homeostasis is vital for insect development and metabolism, and the endoplasmic reticulum (ER) is a major intracellular reservoir for Ca2+. The inositol 1,4,5- triphosphate receptor (IP3R) and ryanodine receptor (RyR) are large homotetrameric channels associated with the ER and serve as two major actors in ER-derived Ca2+ supply. Most of the knowledge on these receptors derives from mammalian systems that possess three genes for each receptor. These studies have inspired work on synonymous receptors in insects, which encode a single IP3R and RyR. In the current review, we focus on a fundamental, common question: “why do insect cells possess two Ca2+ channel receptors in the ER?”. Through a comparative approach, this review covers the discovery of RyRs and IP3Rs, examines their structures/functions, the pathways that they interact with, and their potential as target sites in pest control. Although insects RyRs and IP3Rs share structural similarities, they are phylogenetically distinct, have their own structural organization, regulatory mechanisms, and expression patterns, which explains their functional distinction. Nevertheless, both have great potential as target sites in pest control, with RyRs currently being targeted by commercial insecticide, the diamides.

Biotype B

Whiteflies are phytophagous insects, whose nymphs and adults suck the phloem sap, causing direct damage due to host plant weakness. In tomato (Lycopersicon spp.) crops, they are important vectors of limiting fitoviruses. The objective of this study was to determine the effects of Lycopersicon spp. genotypes on Bemisia tabaci (Gennadius, 1889) biotype B development under greenhouse conditions. The evaluated genotypes were LA462 (L. peruvianum), LA716 (L. pennellii), LA1584 (L. pimpinellifolium), LA1609 (L. peruvianum), LA1739 (L. hirsutum), P25 (L. esculentum), PI134417 (L. hirsutum f. glabratum) and Santa Clara (L. esculentum). LA716 was non-preferred for oviposition by the whitefly, which suggests an antixenotic effect. LA1584 showed an antibiotic resistance because nymphal survival was reduced and nymphal developmental time was increased. Antixenotic resistance was observed in LA1739 and PI134417, based on a reduction of oviposition. PI134417 also reduced nymphal survival, which suggests an antibiotic effect, but LA1739 was suitable for insect development. LA1609 was highly preferred for oviposition, however it reduced insect survival. P25 and Santa Clara (L. esculentum) were highly preferred for oviposition.
