Abstract: Entomopathogenic nematodes, viz.<b style=""> </b><i style="">Steinernema glaseri, S. siamkayai </i>and <i style="">Heterorhabditis indica </i>were formulated in alginate gel capsules and tested <i style="">in vitro </i>at two temperatures (5ºC and 25ºC) for their storage and infectivity against rice meal moth larva, <i style="">Corcyra cephalonica </i>Stainton<i style="">. </i>The nematode<i style=""> S. glaseri </i>survived longer up to 24 weeks and 100 per cent survival was observed up to 4 weeks at 5°C. However, their infectivity was 100 per cent up to 4 weeks at 5°C. It was followed by <i style="">S. siamkayai </i>which survived up to 22 weeks at 5°C and 14 weeks at 25°C. <i style="">H. indica </i>revealed 100 per cent infectivity up to 2 weeks at 5°C and 25°C.
