TLDR
Examination of experimental studies on ecological aspects of the relationship between H. diminuta and tenebrionid beetles reveals strong relationships across host species and strains between prevalence and intensity of infection, efficiency of cysticercoid production and exposure conditions, and variance in abundance orintensity of infection relative to their respective means.Abstract:
The cestode Hymenolepis diminuta (Cyclophyllidea) uses a variety of insects as its intermediate host, where ingestion of eggs results in development in the hemocoel of a cysticercoid that is infective to a rat definitive host. Species in 2 genera, Tenebrio and Tribolium (Coleoptera: Tenebrionidae) have been used extensively as laboratory intermediate hosts. This review examines experimental studies on ecological aspects of the relationship between H. diminuta and tenebrionid beetles, including the acquisition and establishment of the parasite, host effects on the parasite, and parasite effects on the host. A meta-analysis of infection results from the literature revealed strong relationships across host species and strains between (1) prevalence and intensity of infection, (2) efficiency of cysticercoid production and exposure conditions, and (3) variance in abundance or intensity of infection relative to their respective means. The underlying mechanisms producing these patterns remain elusive....read more

Health Hazards Associated with Arthropod Infestation of Stored Products
TL;DR: Insects may actively or passively contribute to the spread of microorganisms, increasing product contamination, and they may host bacteria that have developed antibiotic resistance, contributing to their spread in food.

Sustainable farming of the mealworm Tenebrio molitor for the production of food and feed.
TL;DR: The mass rearing of the mealworm Tenebrio molitor is reviewed, focusing on challenges such as the contamination of food/feed products with bacteria from the insect gut and the risk of rapidly spreading pathogens and parasites.

Lessons from genome skimming of arthropod-preserving ethanol

TL;DR: Comparison of diversity profiles of microbiota in specimen and ethanol samples showed that ‘closed association’ (internal tissue) bacterial species tend to be more abundant in DNA extracted from the specimens, while ‘open association” symbionts were enriched in the preservative fluid.

Mass spectrometry analysis of the excretory-secretory (E-S) products of the model cestode Hymenolepis diminut a reveals their immunogenic properties and the presence of new E-S proteins in cestodes.

TL;DR: This is the first study identifying E-S-proteins in adult tapeworms, thus providing information for better understanding host-parasite interrelationships, and may point out potential targets for vaccines or drug discovery studies, as among the proteins observed in the study are those known to be antigens.

TL;DR: Be Beetles treated with a broad-spectrum antibiotic exhibited significantly reduced parasite establishment compared with the untreated control group, indicating that the host microbiome may greatly influence hatching of eggs and subsequent establishment of H. diminuta larvae.

TL;DR: That lexity is an inherent and avoidable outcome of natural systems is a major theme of this book and I have little doubt that it will help improve countless diverse, human agendas.

Patterns of macroparasite abundance and aggregation in wildlife populations: a quantitative review
D J Shaw,Andrew P. Dobson +1 more
TL;DR: Using a relatively new technique for parasitological infection data - tree-based models, as well as traditional linear models - a number of the parasitic infections was found to be associated with systematically lower or higher parasite burdens.

TL;DR: Hilary Hurd uses examples of parasitized insects and trematode infections of snails to consider the evolutionary significance of this response to infection in host fecundity reduction.

Physiological and behavioural interactions between parasites and invertebrate hosts.
TL;DR: In this article, a host-parasite association succeeds only if the host survives long enough to enable the parasite to complete the particular phase of its life cycle and if a host population is able to persist in time.

On satiation curves
TL;DR: It is demonstrated that for a laboratory rat feeding in a Skinner box the most satisfactory description of this curve is a negative exponential with three parameters, predicted both by causal theories of satiation involving negative feedback, and by a functional explanation using optimality theory.
