Abstract

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.
