Resumen

Dear Sir,
Compatibility between Heterorhabditis bacteriophora Poinar strain HC1 and Lecanicillium lecanii (Zare and Gams) strain VERTICEN 01 was evaluated in Galleria mellonera Fabricius as key insect under laboratory conditions using a random design with four treatments. The treatments were the application of nematodes alone, nematodes + fungi, fungi alone, and G. mellonella last instar larvae without treatment as the: control. The evaluations were made each 24 hours during four days. A mortality of 100% was observed in G. mellonella when nematodes alone or nematodes + fungi were applied; whereas in the treatment control (without bio-regulators) and the treatment with L. lecanii, mortality reached only 3%. The effect of H. bacteriophora in G. mellonella showed the existence of
compatibility between this entomopathogenic nematode and L. lecanii. The treated G. mellonella larvae exhibited the typical symptoms of HC1 strain effect.
