Research Papers: Effect of Temperature on Development and Reproduction of Globodera solanacearum

Abstract

The rate of development, size of cysts, and number of eggs and larvae in cysts of Globodera solanacearum varied with different soil temperatures. The life cycle was completed in 33 days at 27 C, 38 days at 32 C, 43 days at 21 C, and more than 48 days at 15 C. Cyst size and number of eggs and larvae therein were greatest at 27 C. Both cyst size and numbers of eggs and larvae decreased at temperatures above and below 27 C, but reduction in number of eggs and larvae per cyst greatly exceeded reduction in cyst size at 15 and 32 C.
