Exposure to different constant temperatures (12, 17, 22, 27 or 32°C) during the entire life-span of femaleLysiphlebia mirzaivariously affected its longevity, life-table parameters, developmental rate, and mortality of developmental stages of the progeny. The parasitoid develops much faster at 32°C than 12°C. Lower threshold temperature for the development (t1) was 3.02°C and predicted time-to-adult 339.93 degree days. Higher percent mortality occurred at 32°C and 12°C than at 22°C. The adult survived much longer (17 days) at the lower extreme temperature than at the higher one. However, net fecundity (daughters/female) and total fecundity rates (progeny/female) were lowest at 12°C. The female produced the highest number of daughters (163.8) and progeny (242.6) at 22°C. Life-table parameters were temperature dependent; rmwas greater than 0.3 at ≥ 22°C. The results reveal an optimum range of temperatures at whichL. mirzaiperforms well. Most of the life- table parameters vary little between 17 and 27°C, thus, the parasitoid may be adapted for a wide range of temperatures and thus well suited for biocontrol of the cereal aphidRhopalosiphum maidis, in areas where temperatures vary within this range, as in the plains of north India.
