gum in powder and hydrated forms
A food-grade gum substance shows promise as a new tool for managing the invasive spotted-wing drosophila (Drosophila suzukii). The gum is an odoriferous concoction of a food-grade, plant-based powder (left), containing materials such as agar gel, cellulose, pectins, and fructose and glucose sugars, mixed with water into a jelly (right).
