Extract

Nippostrongylus brasiliensis of either sex, 216 h old, were injected directly in the intestinal lumen of 10-week-old laparotomized male rats in the duodenum or near the ileocaecal valve and their position ascertained 24 h later. Males migrated anteriad farther when females were placed in the duodenum than when they were alone or when 32P tagged males were in the duodenum. Females migrated anteriad similarly when they were alone or when males were in the duodenum or when 32 P tagged females were injected in the duodenum. The findings are consistent with the idea that females attract males anteriad at a distance.
