HAIRWORM PARASITES.^ Hairworm parasites of the codling moth (PL I, figs. 5, 6) were found at Greenwood, Keyser, and French Creek, being abundant m the second-brood larvae at the latter place m 1911. These parasites were within the bodies of the codling-moth larvae at the time collections. Fig. 23.—Itopledis marginatus, a parasite of the codling moth. Enlarged. (Original.) were made from the bands and usually issued from their hosts 10 days or 2 weeks after the larvae were placed in the rearing j ars. Occasionally dead larvae, surrounded by a mass of dead hairworms, were found under the bands, and in a few cases the hairworms were found within apples borne by the banded trees. It was evident that mfestation occurred at an early stage in the larval development and that all infested indi- viduals died as full-grown larvae. Most of the parasitized larvae died within 10 days after being placed in the rearing jars. The hairworms v»^ere from 2J to 5 inches in length, and three or four were frequently observed to inhabit one larva. In leaving the host they passed through the anal opening or broke through the 3 Mcrmis sp. Material was referred to Dr. B. H. Ransom, of the Bureau of Animal Industry, Init as the specimens were all immature, they could not be determined Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
