ABSTRACT:
Laboratory studies were undertaken to evaluate the role of environmental factors on the development of free-living stages of the cat hookwormAncylostoma tubaeforme. An index of development calculated from the proportion of eggs that developed to the infective stage and the reciprocal of the development period, has suggested that the absence of high temperatures (26–30C) would significantly affect the L3 population in contaminated soils.There were, however, no significant differences in the size and lipid content of L3 that had developed at the different temperatures.
