Light Sense in Nematodes

Peter A. G. Wilson 1

1 Zoology Department, University of Edinburgh, Scotland

The stimulating effect of daylight on the oxygen uptake of the infective larvae of Haemonchus contortus and Nippostrongylus basiliensis, measured at constant temperature, provides the first proof of a dermal light sense in the Nematoda. Nippostrongylus larvae are less sensitive than those of Haemonchus and require very high light intensities before a significant effect can be detected.
