Fig. 4From: Ethyl formate and phosphine fumigations on the two-spotted spider mite, Tetranychus urticae and their biochemical responsesMALDI-TOF MS/MS chromatograms of lipids of Tetranychus urticae adults after ethyl formate (EF) and phosphine (PH3) fumigation. a Control group; b EF-treated group; c PH3-treated group. d Indicates two major peaks as 815.46 and 859.54 m/z, which are differently produced according to fumigant treatments. e Shows PCA analysis on peaks in the chromatogram with the fumigant treatmentBack to article page
