. Bulletin - Massachusetts Agricultural Experiment Station. Agriculture -- Massachusetts. CRANBERRY FRUITWORM Fig. 39. Cranberries with worm holes, one closed with white silken curtain. Fig. 40. How the worms often work from one cranberry directly into another. Fig. 41. Cranberries shriveled to dry husks because of its work. 1923, and in the Grayland distiict about 1936 (D. J. Crowley and H. F. Bain). It is not found in Oregon. The worms infest in the wild the fruits of the mountain cranberry^S and swamp blueberry and are sometimes a considerable pest in cultivated fields of the latter. They commonly web together several berries of these plants and feed among them. They probably have still other food plants, for they eat dangleberries, black huckleberries, apples, and beach plums freely in confinement. Character of Injury The newly hatched larva almost always crawls over the surface of the cran- berry from its place of emergence at the blossom end and enters close to the stem or goes to find another berry. If, however, the berry is held with the blossom end up, the worm enters at that end. Its entrance is so small that it is barely visible to the unaided eye. It eats the seeds and usually more or less of the pulp and then leaves the berry to enter a second. One worm destroys from three to six berries, the number varying with their size. Most of the pulp is eaten in all ^ Vaccinium Vitis-Idaea L. var. minus Lodd. [53].
