Abstract:

The effect of temperature on mortality and time for larval development (considered as the expression of resistance) of a leaf miner, Liriomyza nunda Frick, in 17 tomato varieties and 19 chrysanthemum cultivars was compared with that of larvae in lima bean, the susceptible standard. Mortality in lima beans ranged from 8 to 16% at temperatures between 15.6 and 35.4, but the mortality was not consistent with the changes in temperature. Time for larval development on bean decreased as temperatures increased from 15.6 to 26, but little additional decrease occurred with temperature above 26. Mortality was highest in the 1st larval instar, intermediate in the 2nd instar, and least in the 3rd. At comparable temperatures, larval development was more rapid in bean than in tomato or chrysanthemum and was generally more rapid in tomato than in chrysanthemum. Also, mortality in tomato and chrysanthemum increased significantly with decreasing temperatures. With chrysanthemum, there was a correlation between the longer time for larval development and the higher larval mortalities in those cultivars considered resistant; none was observed with tomato varieties.
