Volatile constituents of male and female boll weevils and their frass
Journal of Insect Physiology, 1974Abstract The volatile constituents of male and female boll weevils, Anthonomus grandis , and their frass were analysed by GLC-MS. The 4 previously identified components of the male pheromone were present only in the male volatile oil (3·9%) and in the male frass volatile oil (38·9%).

Fertilizer efficiency and induced chitinase activity of frass versus frass biochar amended to soil
Insect production of “black soldier fly” (BSF) larvae is an efficient and sustainable method to convert residual biomass into useful products. A byproduct from insect production, consisting of larval excrement, residual feed and larval exoskeletons, known as “frass,” contains essential macro- and micronutrients ...openaire +1 more source
