Abstract: A method for producing microcrystalline cellulose by the steps of subjecting a cellulose source material to steam explosion treatment, extracting the steam treated cellulosic material to remove hemicellulose and lignin, and recovering microcrystalline cellulose that is substantially colloidal in particle size and essentially free of fibrous cellulose.

Abstract: A method of treating a population of social insects includes applying topically to the insect a composition comprising a carrier and an active ingredient. The composition provides a coating that adheres to the insect and is groomable and ingestible by other insects to distribute the active ingredient within the population. In accordance with a preferred embodiment, the composition includes sulfluramid as an active ingredient and an air dryable resin as a carrier. A trap for collection of insects controls temperature within the trap to promote recruitment and also drive the insects to a collection area where they may be treated.
