Temporal Dynamics and Electronic Nose Detection of Stink Bug-Induced Volatile Emissions from Cotton Bolls

Table 3

Accuracy of E-nose training sets used to identify 10 unexposed bolls (control) and 10 bolls exposed to Nezara viridula collected during a 96 hr feeding trial.

Time	Treatment	Correct^a	Incorrect^b	Identification accuracy
24 hr	N. viridula	5	5	50%
	Control	7	3	70%
48 hr	N. viridula	4	6	40%
	Control	9	1	90%
72 hr	N. viridula	9	1	90%
	Control	10	0	100%
96 hr	N. viridula	8	2	80%
	Control	10	0	100%

^aClassification includes total number of bolls correctly identified by E-nose (damaged or control).
^bClassification includes total number of bolls incorrectly identified by E-nose (false, confused, unknown).
