An economical method of dispensing specific volumes of diet for Heliothis spp. larvae into multiple containers (compartments of disposable plastic trays or plastic cups) was devised. The system uses a tubing pump and an easily fabricated dispensing head. It can be used with other diets that contain fine particles and have low viscosity. The apparatus is easily taken apart for cleaning and sterilization. Repeatability of dispensing the diet was ± 1–2%; accuracy of dividing the diet into portions was ± 1–5%.
