| description | BACKGROUND
The redbanded stink bug Piezodorus guildinii (Heteroptera: Pentatomidae) is one of the most important species affecting soybean crops in southern South America. Capillary gas chromatography coupled to mass spectrometry was used to characterize the epicuticular hydrocarbon profiles of field‐collected insects, and to identify differences in their composition between fifth‐instar nymphs and adults, males and females, and between bugs collected in insecticide‐treated and insecticide‐free soybean crops.
RESULTS
Straight chain saturated n‐C27 and n‐C29, and monomethyl and dimethyl chains of C31 and C33 were the most abundant compounds. A group of volatile hydrocarbons with n‐C13 and n‐C15 as the predominant compounds were also detected. The hydrocarbon pattern was different between nymphs and adults, either males or females. Heneicosene was almost exclusively detected in adult males and was the most important component to differentiate between both sexes, followed by tricosadiene. The total hydrocarbon amount was significantly higher in nymphs, males and females collected in insecticide‐treated fields compared with insects obtained from untreated fields.
CONCLUSION
Differences were found in the epicuticular hydrocarbon pattern among nymphs and adults, as well as sexual dimorphism in adult stink bugs. Interestingly, an alteration was also found in the hydrocarbon profile of insects collected in insecticide‐treated soybean crops and its relevance is discussed within a pest management context.
Capillary gas chromatography coupled to mass spectrometry was used to characterize the epicuticular hydrocarbon profile of field‐collected juvenile and adult Piezodorus guildinii, and to identify differences in its composition between nymphs, males and females, to detect sexual dimorphism, and between bugs collected in insecticide‐treated and insecticide‐free soybean crops, to detect changes in the epicuticular hydrocarbon pattern related to insecticide exposure.
