The life cycles of the leaf miners, Liriol1lyza trifolii (Burgess) and Liriomyza sativae (Blanchard), were studied in a growth chamber (Temp, 25 ± 1 deg C; R.H. 75 ± 5%; L/D 12 hL/12 hD and 3000 - 4000 LUX) at CIRAD, Montpellier, France. The host plant used was haricot bean (Phaseolus vulgaris). The egg incubation period of both species lasted for two days. Highly significant differences (P 0.0l) were recorded between the number of feeding punctures caused by L. trifolii and L. sativae. Differences between the larval periods and number of emerging adults were not significant. Upon hatching, during 1996, the number of larvae of L. trifolii was significantly higher than that of L. sativae, but the total life span of L. sativae was significantly longer than that of L. trifolii
