1. Caste‐biased locomotor activities in isolated termites

Author:
Hiroyuki Shimoji; Nobuaki Mizumoto; Kohei Oguchi; Shigeto Dobata
Source:
Physiological entomology 2020 v.45 no.1 pp. 50-59
ISSN:
0307-6962
Subject:
Hodotermopsis sjostedti; labor; locomotion; morphometry; multivariate analysis; reproductives; social behavior; social insects
Abstract:
... Eusocial insects are characterized by a well‐developed division of labour among castes. Although the successful division of labour should stem from behavioural differentiation depending on caste identity, caste‐specific intrinsic behavioural characteristics might be masked by social interactions within colonies. The present study explores caste‐specific intrinsic locomotive activities of termites ...

Abstract:
... In the present study, the lipid composition from male and female Hylobius abietis is analyzed pre‐ and post‐infection with Beauveria bassiana. The compounds are analyzed by gas chromatography‐mass spectrometry. In the lipids of males and females fatty acids, fatty acid methyl esters, alcohols, amino acids and other organic compounds are identified. The lipids of males and females after B. bassiana ...

Mamestra configurata; Trichoplusia ni; adults; alpha-linolenic acid; aquatic ecosystems; biomass; crops; docosahexaenoic acid; eicosapentaenoic acid; experimental diets; fatty acid composition; genetic engineering; herbivores; insect pests; linoleic acid; nutritional intervention; omega-3 fatty acids; plant pests; vegetable oil
Abstract:
... The long‐chain omega‐3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are prevalent in aquatic ecosystems and are not part of the natural diet of herbivorous, terrestrial insects, which generally consume alpha‐linolenic acid (ALA) and linoleic acid (LNA). However, recent advances in genetic engineering have lead to the development of terrestrial crops that express the novel ...

Calliphora vicina; Lucilia sericata; adults; body size; carrion insects; ecosystems; insect larvae; insect physiology; instars; life history; models; predators; pupae; rearing; survival rate; temperature; Central European region
Abstract:
... The present study focuses on trade‐offs between the development rates and their life‐history traits of feeding larvae. Indeed, quick growth is considered to be vital for necrophagous insects such as larvae because they are part of a rapidly changing ecosystem and at the mercy of many predators. However, excessively quick growth can have a negative effect on other life‐history traits (e.g. survivor ...

Abstract:
... Chemical trails of the hosts (footprints) are important cues for the host searching behaviour of egg parasitoids of the family Scelionidae. The present study aims to determine the influence of the footprints of three neotropical stink bugs (Euchistus heros, Dichelops melacanthus and Nezara viridula) on the foraging behaviour of two parasitoids, Trissolcus basalis and Telenomus podisi, as well as a ...

Solenopsis invicta; biotic factors; environmental factors; fire ants; food availability; foraging; gene expression; genes; habitats; models; polyphenism; reverse transcriptase polymerase chain reaction; temperature
Abstract:
... The behavioural plasticity and adaptability of some insects, allowing them to adapt to diverse habitats, is strongly associated with foraging genes (for). The role of the foraging gene is closely related to insect polyphenism and some abiotic and biotic factors. The red imported fire ant Solenopsis invicta Buren (Hymenoptera: Formicidae) has successfully expanded its global range and is considered ...

Mantodea; aminopeptidases; beta-glucosidase; carnivores; cell walls; chitinase; developmental stages; diet; digestive enzymes; enzyme activity; herbivores; insects; midgut; molting; secretion
Abstract:
... In all developmental stages, the phasmid Peruphasma schultei (Conle & Hennemann, 2005) is an obligate herbivore, whereas the mantid Hierodula membranacea (Burmeister, 1838) is an obligatory carnivore. In P. schultei, the luminal activity of all enzymes is approxximately 50% in the crop and 50% in the midgut, which corresponds to the approximate 50 : 50 ratio of volumes of these two regions. These ...

Subject:
Nematoda; Odontotaenius disjunctus; energy; energy requirements; hosts; insects; oxygen consumption; parasites; parasitism; pathogens; tissue repair
Abstract:
... The rigours of the daily lives of insects sometimes lead to minor injuries and wounds, which must be healed to avoid entry of pathogens and to resume normal function. Such healing requires energy, which must be diverted from other bodily reserves. What happens if energy reserves are already low, as would occur in individuals coping with internal parasites? This question is addressed in the presemt ...

Abstract:
... It is widely accepted that male age can influence female mating preference and subsequent fitness consequences in many polyandrous species, yet this is seldom investigated in monandrous species. In the present study, we use the monandrous pine moth Dendrolimus punctatus to examine the effects of male age on female mating preference and future reproductive potential. In multiple male trials, when p ...

circadian clocks; cold treatment; latitude; midges; monitoring; oxygen consumption; photoperiod; seasonal variation; summer; temperature; winter; Antarctic region
Abstract:
... Seasonal progression is tracked in most animals by changes in daylength, thus allowing reliable synchrony with abundant food and favourable developmental conditions. In polar regions, daylength varies extensively, fluctuating at the highest latitudes from persistent light to persistent dark. The Antarctic midge Belgica antarctica has a narrow seasonal window in which to feed and develop, and previ ...
