	abstract = {The influence of temperature on the development and embryonation of Ascaris suum eggs was studied using coarse sand medium in an environmental chamber with 50\% humidity. The time required for development and embryonation of eggs was examined under 3 different temperature conditions, 5{\textcelsius}, 25{\textcelsius}, and 35{\textcelsius}. A. suum eggs did not develop over 1 month at the temperature of 5{\textcelsius}. However, other temperature conditions, 25{\textcelsius} and 35{\textcelsius}, induced egg development to the 8-cell-stage at days 5-6 after incubation. All eggs examined developed to the 8-cell stage at day 6 after incubation in the sand medium at 25{\textcelsius}. The higher temperature, 35{\textcelsius}, slightly accelerated the A. suum egg development compared to 25{\textcelsius}, and the development to the 8-cell stage occurred within day 5 after incubation. The formation of larvae in A. suum eggs at temperatures of 35{\textcelsius} and 25{\textcelsius} appeared at days 17 and 19 after incubation, respectively. These findings show that 35{\textcelsius} condition shortens the time for the development of A. suum eggs to the 8-cell-stage in comparison to 25{\textcelsius}, and suggest the possibility of accelerated transmission of this parasite, resulting from global warming and ecosystem changes.},
