In: Egyptian Journal of Biological Pest Control 2007.v.17(1)Summary: Steinernema carpocapsae strain All and Heterorhabditis bacterionphora strain HP88, Dipel-2X (Bacillus thuringiensis subsp. kurstaki) and peppermint oil (Mentha piperita) were assayed for the control of Sesamia crellea Led. tested under laboratory and field conditions. The efficacy of S. carpocapsae was a concentration dependent. The lower concentrations (25 and 50 IJs/ml) had no effect within one day; while they showed mortality percentages between 60.0 and 73.3 % after two days. Th., higher concentration levels (100,200 and 400 Us/ml) caused mortality percentages ranged between 20.0 and 33.3 % within one day.
