The accumulation of cull potato piles is a concern because they take up space and harbor potato-associated pathogens. Black soldier fly, Hermetia illucens, larvae are an increasingly popular agent for converting organic wastes into ingredients for animal feeds. In this investigation, their ability to process cull potato waste was assessed. Potato tubers were suitable for
The Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae) is an insect defoliator of the potato, Solanum tuberosum L. This species thrives in agricultural environments because of its flexible and complex life history, as well as its ability to evolve insecticide resistance. As a result, it has become a widely distributed agricultural pest. Ledprona (trade
The Colorado potato beetle, Leptinotarsa decemlineata (Coleoptera: Chrysomelidae) is a destructive pest of the cultivated potato, Solanum tuberosum. Members of this species are well-suited to agricultural habitats because of a suite of physiological adaptations and their ability to evolve resistance to multiple insecticides. Recently, a novel double-stranded RNA (dsRNA) insecticide (Calantha, active ingredient ledprona) has
Bacillus cereus is a common and ubiquitous bacterium that can cause foodborne illnesses in humans and other animals. Common methods of contact between foodborne pathogens and their victims include exposure through contaminated food or food containment products. Using larvae of black soldier flies, Hermetia illucens, for biological conversion of wastes into components of animal feeds
Larvae of black soldier flies, Hermetia illucens, are increasingly used for biological conversion of animal and plant wastes into ingredients of animal feeds on an industrial scale. The presence of pathogenic microorganisms in harvested larvae may be a serious problem for wide-scale adoption of this technology. Fortunately, black soldier fly larvae may have some antimicrobial
The molecular and biochemical properties of two acetylcholinesterases (LdAChE1 and LdAChE2) from the Colorado potato beetle, Leptinotarsa decemlineata, were investigated in this study. Polyacrylamide gel electrophoresis in conjunction with western blotting with LdAChE1- or LdAChE2-specific antibodies suggested that LdAChE1 exists in a soluble form, whereas LdAChE2 exists in both soluble and amphiphilic forms with a
BACKGROUND: The Colorado potato beetle, Leptinotarsa decemlineata (Coleoptera: Chrysomelidae) is one of the most notorious pests of the potato, Solanum tuberosum. Potato beetles are capable of developing resistance to various insecticides in relatively few generations. Novel and effective means of controlling Colorado potato beetle populations are constantly required to protect potato crops and prevent loss
Biological conversion of agricultural wastes into animal feed ingredients using larvae of black soldier fly (Hermetia illucens) is a promising technology that improves the sustainability of agriculture. We designed and tested a prototype automated incubation system for producing black soldier fly larvae. The system consisted of six 50 L plastic bins enclosed on a ventilated
Colorado potato beetle (CPB, Leptinotarsa decemlineata) is a major pest of potato and other solanaceous vegetables in the Northern Hemisphere. The insect feeds on leaves and can completely defoliate crops. Because of the repeated use of single insecticide classes without rotating active ingredients, many chemicals are no longer effective in controlling CPB. Ledprona is a
