Table 1 The mean of accumulated mortality percentage of the 2nd instar larvae of FAW at 10 days after application of the EPNs Heterorhabditis indica isolate AUT 13.2 and Steinernema siamkayai isolate APL12.3 in the laboratory condition

Larval stage	Concentrations of EPNs (IJs/ml)	EPNs
		H. indica AUT 13.2	S. siamkayai APL 12.3
		Mean (%)	Mean (%)
2nd instar	Control (distilled water)	0.0a	0.0a
	50 IJs/ml	27.5b	17.5b
	100 IJs/ml	42.5c	27.5c
	150 IJs/ml	55.0d	35.0d
	200 IJs/ml	65.0e	47.5e
	250 IJs/ml	82.5f	65.0f
	300 IJs/ml	80.01f	67.5f

The means in each column followed by a common letter are not significantly different by the Duncan multiple range tests at 5% level
