7.8.4. Feeding a solid test substance to groups of adult workers caged in the laboratory

Test substances can also be provided orally to a group of caged workers in a solid form, such as in 95% (weight/weight) sucrose paste (section 7.2.1.3). See section 7.8.3. for a discussion on feeding a group of workers in a single cage. Ensure the solid test substance is well mixed and homogeneous, and perform a pre-trial to determine how much sucrose paste is required.
