الملخص EN

The potential use of Mediterranean flour moth Ephestia kuehniella larvae for the rearing and propagation of some entomopathogenic nematode isolates collected from Damascus province soils was investigated.

Four nematode isolates were used: VH11 (Heterorhabditisindica), PHA and DKH9 of Heterorhabditis sp.

and RST of Steinernema sp.

These isolates were used in five concentrations (1000, 500, 250, 100, 50 infective individuals/ml).

The results showed that Ephestia kuehniella was very sensitive to nematode infection, and the entomopathogenic nematode life cycle in it was shorter than that in larvae of wax moth.

The quantitative production was identified as the number of nematodes in a fixed weight (0.02g) of insect host.

The average production of wax larvae ranged between 10 and 15 thousand individuals in wax moth larva, and 36-57 thousands in Ephestia kuehniella.

The flour moth larvae significantly produced more infective individuals than larvae of wax moth.
