Abstract

Leaf-mining Diptera, Liriomyza trifolii (Burgess) completed its life cycle from egg to adult in 14–21 days with a mean of 18.86 days on French bean. The egg, larva, pre-pupa, pupal and adult stages lasted for 4.85±0.67, 3.6±0.59, 0.21±0.17, 10.20±0.83 and 1.90±0.308 days, respectively. The percentage of pupation and adult emergence was 83.0 and 85.7, respectively. The average fecundity was 29 and the maximum number of eggs (15.8/female) was laid on the second day of captivity. The oviposition period lasted for 6 days. The sex-ration was (female: male) 1:0.69. The ratio of oviposition: feeding punctures was 1:6.93.
