It had previously been shown that blow-fly larvae fed on fatigued frog muscle grow to a larger size than controls fed on resting muscle. I have now demonstrated that the growth-stimulating substance is thermolabile and that it passes from the contracting muscle into the blood stream. It does not accumulate in the liver. The bacterial flora is equally dense on resting and on fatigued muscle on which fly larvae have fed.

Blow-fly larvae were fed on (1) resting, and (2) fatigued frog muscle. The larvae fed on fatigued muscle attained a body weight 9 per cent. greater than those fed on resting muscle, and the rate of their heart beat was increased by 14 per cent. The length of larval life and the oxygen consumption was the same in the two sets of larvae.

Stimulation Of

The uptake of 2-[3H]deoxyglucose, a non-metabolisable derivative of glucose, was studied in resting and contracting muscle. An isolated phrenic nerve/hemidiaphragm preparation of the mouse was used, and contractions of the muscle were elicited by electrical stimulation of the nerve. beta-Endorphin stimulated the uptake of 2-deoxyglucose in resting diaphragm muscle. The rate of uptake in the presence of the optimum concentration of beta-endorphin was similar to that in the presence of the optimum concentration of insulin over the short incubation period. beta-Endorphin also stimulated the uptake of 2-deoxyglucose in contracting muscle, but the optimum concentration of the peptide for this effect was three orders of magnitude lower than in resting muscle. The optimum concentration for insulin, however, was similar in resting and contracting muscle. An analogue of the C-terminal tetrapeptide of beta-endorphin also stimulated 2-deoxyglucose uptake, but this peptide was equally efficacious in resting and contracting muscle. It is suggested that beta-endorphin, which is released into the circulation during exercise, may have a hormonal action to increase the uptake of glucose during muscular activity. This peptide or its metabolites may be partly responsible for the insulin-independent uptake of glucose during exercise.

Black soldier fly, Hermetia illucens (L.) (Diptera: Stratiomyidae) can be used for recycling a wide variety of organic wastes. However, these wastes are also suitable for colonisation by pest fly species, including the blow fly Lucilia sericata (Meigen) (Diptera: Calliphoridae), and by pathogenic microorganisms. We tested effects of the presence of black soldier fly larvae (BSFL) on recruitment and retention of blow fly larvae, as well as on composition and dynamics of microbial communities in finfish-based substrates. Substrates inhabited by BSFL contained approximately one-tenth of the L. sericata pupae found in the control substrate even when BSFL were removed prior to the introduction of gravid L. sericata females. Furthermore, almost three-quarters of L. sericata released into substrates previously colonised by BSFL emigrated within 24 h, while no such emigration was detected for the control substrates. Unlike previous studies, bacterial community was heavily dominated by Gram-positive species. Overall bacterial abundance on BSFL substrates declined approximately two-fold compared to the control substrate, while fungal abundance increased. However, surviving microbial communities were still robust and diverse, and continued to be dominated by Gram-positive bacteria. On the other hand, Gram-negative Shigella sonnei, which is a common cause of diarrhoea in humans, was more than 200 times less abundant in BSFL substrates compared to the control throughout the experiment. Repellent and antibiotic properties observed in this study are advantageous for using BSFL in remediation of finfish wastes. However, additional treatment of remaining residue may still be necessary to eliminate all biological contamination.
