You may have experience with two and four footed livestock but how about livestock with six or no legs?

Larval and adult black soldier fly.

Composting farm and food wastes has become increasingly important to management of small farms. However, some food wastes are difficult or impossible to process using hot compost or vermicomposting techniques. Arthropod based composting using black soldier flies is an attractive option because the flies can process high oil and protein sources that worms cannot. In addition black soldier flies make a great feed source for fish and foul and common composting systems incorporate "self harvesting.'

Thrips, fungus gnats and other soil borne pests are a consistent problem in greenhouse, hoop house and some open field agriculture crops. Thrips are especially challenging to manage due to their rapid development of insecticide resistance. Augmentative biological control provides a good alternative to insecticides when available. Entomopathogenic nematodes and predators like D. coriaria are two biological control organisms with a track record of use for Integrated Pest Management (IPM) of a variety of soil insects including thrips. Sourcing these natural enemies can be challenging, so learning to rear your own can make them a more feasible pest management option.
