Summary of mean treatment dosages, costs, uptake times and changes in galled to total leaf area and insecticide residues recovered from leaf tissues in Erythrina sandwicensis at Pu’u-o-kali, Maui, HI, U.S.

Treatment	DBH^{^z}	Dose	Cost	Uptake	% Galled/Total Leaf Area (cm²)		PPM^{^y} (35 d) (13 mo)
Treatment	(cm)	(mL)	(per tree)	Time (min)	(0 d)	(394 d)	(35 d)	(13 mo)
Emamectin	42.8a	172a	$45	16.7a	3.39a	13.56a	0.63	ND^{^x}
Imidacloprid	41.2a	131b	$46	21.6a	1.79a	2.95b	7.67	23.34
Untreated	45.6a	N/A	N/A	N/A	1.98a	11.07a	0.00	0.00

↵^zMeans followed by the same letter in a column are not statistically different, n=19-20 trees per treatment.
↵^yValues are uncorrected for percent efficiency of chemical extraction.
↵^xMinimum detectable limit = 0.01 PPM.
