| Abstract/Description: | Penetration and infectivity of eight native isolates of entomopathogenic nematodes (EPNs),Heterorhabditis sp.(IISR-EPN 01); Steinernema sp.(IISR-EPN 02); S. ramanai (IISR-EPN 03); S.carpocapsae (IISR-EPN 06), Oscheius gingeri (IISR-EPN 07) and Oscheius spp. (IISR-EPN 04, 05 and08) were evaluated against larvae of leaf feeder (LF) Lema sp.infesting turmeric. Among the testedEPNs, Steinernema sp.(IISR-EPN 02) and O. gingeri (IISR-EPN 07) were more pathogenic to LFlarva as they brought about 100% mortality to the insect within 48 h post exposure, followed byHeterorhabditis sp.(IISR-EPN 01) and Oscheius sp. (IISR-EPN 08) after 72 h of exposure. S. ramanai(IISR-EPN 03) and Oscheius spp. (IISR-EPN 04 and 05) took 96 and 120 h, respectively, to kill thetest insect. Lema sp. larvawas the most suitable host for multiplication of infective juveniles (IJs)of O. gingeri (IISR-EPN 07), which yielded 11, 480 IJs larva-1, followed by Steinernema sp.(IISR-EPN 02) (8, 658IJs larva-1) and S. carpocapsae (IISR-EPN 06) (6, 810 IJs larva-1), however,Heterorhabditis sp.(IISR-EPN 01) less multiplied. The maximum number of Steinernema sp. (IISR-EPN 02) IJs penetrated into test larva(17.5 IJs larva-1), followed by S. carpocapsae (IISR-EPN 06)(10.2 IJs larva-1) and the fewest (2.8 IJs larva-1) were of Oscheius sp. (IISR-EPN 08). The infectivityof the above EPNs against LF is being reported for the first time which opens up a new hope ofutilizing them in insect pest management in turmeric. |
