Abstract

Evaluation of the entomopathogenic nematodes species ,
Steinrnmema rarum, Steinrnmema carpocapsae (Sc), Steinrnmema
spp (S6) and Heterorhabditis spp (HLs) against the prepupae and
pupae of Pegomya mixta, larvae and pupae of Lixus junci and
Hymenia recurvalis was carried out at 25 °C and 65% R.H.
Concentration 500 and 250 IJs/ ml were tested and the results
indicated that the mortality rate increased with increased dosage of
nematodes. The highest mortality was 62.5% for (S6) and (Sc)
against prepual stage of P. mixta at 250 IJs/ml, while it was
moderate mortality was for S. rarum and HLs. The highest
mortality of S. rarum was against pupal stage for some
concentrations and other treatments gave moderate mortality,
compared with the control. Also, the mortality percentages were
the same for all treatments against prepupal and pupal stages at
500 IJs/ml, except for (S6) treatment with 92.5%mortality at the
same concentration.
All nematode species tested gave complete mortality (100%)
for L. junci larvae when applied at either 500 or 250 IJs/ml.
