Embryonic development of Romanomermis communensis (Nematoda:Mermithidae) at different temperatures
Embryos of R. communensis completed their development to the late coil stage in 16.5 days at 20 °C, 22 days at 15 °C, and 32 days at 10 °C. Embryos failed to develop at 5 °C, although 10% did reach the two-cell stage by 32 days. About 5% of the eggs at 20 and 15 °C hatched after embryonation was com...

Summary: | Embryos of R. communensis completed their development to the late coil stage in 16.5 days at 20 °C, 22 days at 15 °C, and 32 days at 10 °C. Embryos failed to develop at 5 °C, although 10% did reach the two-cell stage by 32 days. About 5% of the eggs at 20 and 15 °C hatched after embryonation was completed. There was no further hatching during the 32-day period of observation. The nematode is probably univoltine in its natural habitat near Churchill, Manitoba. |
