Insects and their uses in a cold country: Finland
Victor Benno MEYER-ROCHOW 한국곤충학회 2008 Entomological Research Vol.38 No.-
Northern European countries, despite their geographic location and climatic conditions, have a considerable number of insect species. To date 20 532 species of insects are known from Finland. Honeybees were introduced to Finland in the 18th century. The total number of hives in the country today is 50 000, with each producing an annual 30–40 kg of honey. A considerable amount of research is carried out on bees in Finland by beekeepers and scientists and the Finnish Beekeeper Association publishes its own journal by the name of Mehiläinen for approximately 3300 subscribers. Insects also play important roles in the education and school curricula of Finnish children with insect boxes containing preserved specimens, identification keys and information on general biology available for classes. Some butterflies get framed and hung on walls, serving as room decorations. Insects also feature as motifs on Finnish t-shirts. Forensic entomology was pioneered in Finland and numerous university departments (zoology, entomology, ecology, physiology, biophysics, pharmacology and genetics) as well as museums are engaged in research on insects. Monitoring climate change, insects in Finland (especially Lepidoptera) are highly suitable because of the many years of recorded distributions and abundances of species. Finally, the large amount of idioms in the Finnish language, making reference to insects, testifies to the intimate connection between the Finnish people and the insects of their country.

Out of 26 students (11 male, 15 female) that were blindfolded and held their noses, 14 correctly identified the taste of insects when given pieces of cheese, dried fish, beondaegi (commercially available Korean Bombyx mori silkworm pupae), inago (commercially available Japanese Oxya yezoensis grasshoppers) and white bread to taste. Eight identified one of the food insects and four failed to detect any. Of 11 students given a choice between beondaegi, inago and hachinoko (larval wasps of Vespula flaviceps) most students preferred the inago grasshoppers, three ranked the commercially available hachinoko first and one gave the top position to the beondaegi silkworm pupae. It is concluded that insects, per se, are not terribly easy to identify by taste alone. Given the well documented aversion of especially people of western cultural backgrounds to insects in food, our results suggest that insects processed into flour or pastes have a greater chance to be accepted by the consumer (as they cannot easily be identified by taste alone) than food that displays insect images on its packing. Highlights: For the first time taste tests were carried out to determine whether blindfolded participants who were unable to smell could identify edible insects by taste alone. 46% failed.

The lepidopteran family of the Epipyropidae contains currently 32 known species of moths with larvae that are parasitic on plant and leafhoppers as well as cicadas. This paper focuses on behavioural aspects of the final instar of the cicada parasite Epipomponia nawai (Dyer 1904) on the cicada Hyalessa maculaticollis (de Motschulsky 1866) and represents only the second report of the species from South Korea. This species is a new host for E. nawai in Korea, since in the past it had only been reported once from Meimuna opalifera and Oncotympana fuscata in Korea. Molecular relationships between specimens of E. nawai collected in China, Japan, and Korea were analysed. The Chinese haplotypes fell into two groups: one clearly related to the Korean haplotype, but the other tightly affiliated with the Japanese haplotype. The findings suggest two routes for the occurrence of E. nawai in mainland China. Once the host cicada was dead or too weak to move, the caterpillar crawled away from it, seeking a place to pupate. Very little is known about parasitic Lepidoptera and therefore any information on host species or behavioural aspects is of importance.

Icefish Adaptations to Climate Change on the South Georgia Island Shelf (Sub-Antarctic)
Ryszard Traczyk,Victor Benno Meyer-Rochow,Robert M. Hughes 한국해양과학기술원 2020 Ocean science journal Vol.55 No.2
Icefish populations continue to decline. Historical as well as current over-exploitations of stocks aggravated by climate change are frequently seen as responsible for the decline. However, natural oscillations in Antarctic fish and krill populations associated with natural climatic fluctuations, co-occurring with fisheries exploitation hinder determining the reasons for the population changes and the extent that long-term climate change may play in it. Based on data collected from South Shetland and South Orkney Islands (2956 fish stations) and South Georgia Island (2460 fish stations) covering a period from 1976 to 2017 we sought to relate decreases in krill and icefish populations to predator-prey interactions coupled with global warming influences. Our results show that the situation is complex and that many factors, e.g., competition between different icefish species, food choice and availability, and growth parameters, need to be considered. Pseudochaenichthys georgianus and Chaenocephalus aceratus biomasses, for example, oscillate in opposite directions and the two species differ with regard to the ranges they occupy in cold and warm water years. This reduces their competition for food, so that their combined biomasses oscillate little with thermal changes.

How in the Antarctic icefish, generally, and Pseudochaenichthys georgianus, in particular, otoliths increase in size and build new material as the fish ages and passes through different life phases is largely unexplored. Morphometric details of 3418 otoliths of Ps. georgianus from S. Georgia and 318 from S. Shetland, were processed and proportions of the amounts of collagen and aragonite removed by EDTA were determined for different age groups. Microstructural investigations showed that characteristics of the 3-dimensinal collagen net are the reason for the radial direction and orientation of the aragonite needles of approximately 1.0 µm in length in larval and 2.3 µm in length in adult specimens. Earlier generated increment layers from the primordial centre (PC) in the dorsal direction restrict those of the secondary centre (SC), causing new growth layer accretion in different directions. In the otoliths of larval Ps. georgianus, aragonite layers are 0.89 µm wide while in juveniles and adults they measure 1.45–2.86 µm. Otoliths change from a sphere shape in the larvae to a longish object of irregular outline in the older stages. It is tentaively suggested that the observed otolith shape differences at distinct growth stages are due to physical effects related to swimming speeds at particular water depths and locations. To confirm that otoliths, apart from being useful for age analyses, could also serve to establish correlations between developmental stage and the oceanic environment the fish spend time in, further analyses using additional species and state-of-the-art methods like µCT imaging to evaluate otolith volumes and shapes are required.

A re-assessment of the age structure of the population of the Antarctic icefish Pseudochaenichthys georgianus based on body length data covering the years 1976−2009 and including larvae and postlarvae collected in 1989 and 1990 allowed us to define age groups 0, I, and II as containing fish with respective body lengths of 6−9 cm, 15−27 cm and 27−39 cm. Age at maturity (first spawning) was found to occur in age group III at body lengths that have been falling from 50.1 cm in 1979 to 45.4 cm in 1992. Considering postlarvae together with adult fish, the v. Bertalanffy growth curve parameters were determined as L∞ = 60.62 cm, k = 0.4, t0 = 0.25. Although the reasons for a maturity at shorter body lengths is not fully understood a host of environmental factors like increasing water temperatures and possibly changes in currents, interspecific competition, food availability, etc. are likely to be involved. Global warming (and not primarily overfishing) is likely to have been responsible for the disappearance of larger fish in the surface waters of South Georgia since 1977, for virtually all commercial fishing stopped in the early 1990s. On the other hand, the appearance of numerous younger spawning individuals suggests that larvae do survive in the colder deeper water below 200 m. The biomass of Ps. georgianus oscillates with a 4-year periodicity in contrast to that of the coexisting icefish Chaenocephalus aceratus: the former with a lower biomass in warm years and a higher one in cold years. The biomass of the third species of icefish in the region, i.e. Champsocephalus gunnari, also oscillates, but with a longer periodicity than that involved in the biology of the other two and its biomass increases in contrast to the other two species. The result is that the biomass all three species considered together is rather stable.

Despite the consumption of bee brood in several parts of the world, particularly in the tropical areas, the practice has received comparatively little attention. We have reviewed all the available information on the nutrient composition and functional properties of different developmental stages of honey bee workers belonging to different species and subspecies. Noticing the competent nutrient composition of, in particular, honey bee brood, pupae, and prepupae, we suggest that they could be a potential source of human nutrition as well as animal feed. Moreover, drone brood is an ideal candidate for use as a food or as food ingredient. However, to analyze the functional properties of different honey bee species remains a task for further analysis.

We explored the indigenous local knowledge associated with the use of snails by Baiga people in Baihar tehsil of Balaghat district in central India through interview with a semi-structured questionnaire. Results revealed that Baiga people widely accept snails of 3-5 morpho-groups belonging to Ampullariidae, and Viviparidae family as food. Besides, use of snail as therapeutic agents for ailments like body ache, joint pain, digestion, weakness of bones etc. were found common. Hand-picking of snails from the wild environments as well as agriculture field was the primary way of harvesting edible snails. We advocate the development of a farming system for the continuous supply of snails as a food resource, advancement of scientific investigation of functional properties of them, economic progress of the region and therefore the overall sustainability.
