Abstract:

The larva of the Hessian fly (Phytophaga destructor Say) has a perfect digestive tract similar to other fly larvae. It takes only liquid food and its mouth organs seem well fitted for taking food from the plant tissues. The oesophagus is very slender, the proventriculus well developed, joining the very large ventriculus with a typical oesophageal valve. The paired salivary glands consist of an enlarged basal part and a cylindrical distal portion. The single pair of well developed Malpighian vessels connect with the ilium immediately behind the ventriculus. The posterior portion of the ilium is much constricted and joins the expanded colon with a perfect valve. The larva appears to be well equipped physically to take food from the host wheat plants and a study of its digestive tract fails to explain why it is able to mature more successfully on one strain of wheat than on another.
