Insects have potential as a novel source of protein in feed and food production in Europe, provided they can be used safely. To date, limited information is available on the safety of insects, and toxic elements are one of the potential hazards of concern. Therefore, we aimed to investigate the potential accumulation of cadmium, lead and arsenic in larvae of two insect species, Tenebrio molitor...

Abstract In the context of black soldier fly (BSF) rearing, often residues from production — mainly faeces but also undigested substrate are addressed as frass in a broader sense. As BSF is expanding, valorization organic fertilizer gaining importance. However, contrast to established fertilizers, little known on properties and variation this by-product, which essential for assessing possible a...

Background. The double haul is a unique feature of single-handed fly casting and is used in both fly fishing and fly casting competition. The movement behaviour during the double haul has not been investigated in previous research. Objectives. Describe the coordination of the rod and line hauling movements during distance fly casting. Methods. Elite fly casters performed distance castin...

Effect of Temperature on the Breeding Black Soldier Fly Larvae in Vitro for Basic Health-oriented Research

Objective To investigate the importance of the type of dry fly (artificial floating fly) in catching trout (brown and rainbow) in an English chalkstream. Setting River Kennet, Berkshire. Design Five anglers on five separate occasions spent five hours using a randomly allocated fly from a sample of five types. Participants Five anglers of considerable but varying experience, determination, and o...

Abstract Purpose Objective of this study is the valorisation mass rearing waste fruit flies from sterile insect technique facilities by black soldier into high quality and quantity products as a sustainable utilisation concept. Methods Different ratios medfly in hen feed were used for solder fly (BSF) larvae. The growth rate survival determined. Moreover, gains determined bioconversion rates as...

This note presents an alternative method for bioassays using black fly larvae, with which we intend to provide a simpler but effective tool for accessing data on larvicide efficacy.
