Grasshoppers have two main digestive glands. Salivary Gland and Gastric Cica
1. Salivary Glands: A pair of compound leaf-like salivary glands are present on either side of the alimentary canal crop. Saliva is secreted from salivary glands. Saliva participates in food digestion.
2. Gastric sica: At the junction of gizzard and mesenteron there are 7-8 hepatic sica. Their inner mouth is open to the postural canal and the outer mouth is closed. Acid is secreted from the gastric sac. Nutritious foods aid in digestion. Dr. Siddiq Publications
