The developmental rate of Liriomyza sativae Blanchard on the kidney bean, Phaseolus vulgaris, was determined under 6 constant laboratory temperatures (10, 15 , 20, 25, 27, and 30°C) and was compared with that of L. tnfolii. A degree-day model for predicting immature development was estimated from these data. Developmental times for immature stages of L. sativae were inversely proportional to temperature. Total developmental times for the immature stages varied from 12.7 days at 30 °C to 54.8 days at 15 °C, with larvae ceasing to develop at 10°C. Lower developmental thresholds estimated from linear regression equations between temperature and developmental rate, for the egg, larval, pupal, and total combined life stages were 8.15, 10.96, 11.68, and 11.14°C, respectively. Total effective temperatures estimated for the egg, larval, pupal, and total combined life stages were 54.02, 51.10, 122.79, and 223.70 degree-days, respectively. In general green house conditions, eclosion of L. sativae follows that of L. tnfolii by only 0.6-2.3 days. Our developmental estimates conflict with the results of some authors. Some possible reasons for disagreements are: physiological differences depending on the host plant, genetic differences as a result of long laboratory rearing. We indicate that these factors are closely associated to errors in this kind of study.
