摘要：

A description is given of the effect of alternation of temperature on the emergence of larvae from cysts of the potato-root eelworm. Both potato-root diffusate and anhydrotetronic acid have been used as hatching stimulants. When the temperature is alternated between 25 and 15 degrees C. there is a significant increase in the number of larvae emerging. The effects of using pre-warmed as opposed to cold diffusate on cysts of different ages and of renewing the diffusate twice a week instead of once a week are also examined. A maximum has been found in the response-concentration curve when cysts are stimulated by anhydrotetronic acid.
