The effect of low temperatures on the development of eggs of Ascaris suum Goeze, 1782.

Eggs of A. suum were kept at -10 and -20 degrees C for 12 weeks and subsequently incubated in a thermostat at 28 degrees C. During the incubation, their development was checked every 5 days. It was found that storage at low temperatures slows down their development and reduces the number of eggs successfully completing their embryogenesis.
