Induced volatiles in the interaction between soybean (Glycine max) and the Mexican soybean weevil (Rhyssomatus nigerrimus)

Abstract The present study analyzed the volatile compounds emitted by Glycine max (cv. FT-Cristalina-RCH) soybean plants: healthy plants and damaged mechanically or Mexican weevil Rhyssomatus nigerrimus. SPME method was used to compare profile of in four different conditions. G. infested R. nigerrimus qualitatively quantitatively from that plants. Emission 59 detected treatments. Of these compounds, 19 were identified comparison Kovats index, mass spectrum retention times with those synthetic standards. An increase concentration volatiles (Z)-3-hexenyl acetate compound 1-octen-3-ol observed when damaged. mostly produced plant during infestation male female 1-octen-3-ol, 6-methyl-5-hepten-2-one, (E)-?-ocimene, salicylaldehyde, unknown 10, linalool, methyl salicylate, (Z)-8-dodecenyl (ester 5), ketone 2 geranyl acetone. Behavioral effects insect-plant interaction their conspecifics are discussed.
