The aquatic vegetable Brasenia schreberi Gmel. (Nymphaeales: Cabombaceae), widely cultivated in China, faces severe challenges from pest disturbances. With a field investigation, G. birmanica occurred for several generations the mono-cultivation system. first visual peak on leaf surfaces appeared July, with eggs, larvae, pupae and adults all being recorded. highest number of flying were trapped August reverse to absence beetles leaves, followed by an extraordinary high eggs September. exhibited conspicuous aggregation distribution, severely chewed areas having abundance 21.6 times that non-chewed areas. Laboratory studies GC–MS two-choice tests revealed four volatiles significantly discrepant contents released chewed/intact leaves: cis-3-hexenyl acetate (917.33 ± 29.56 vs. 604.034 23.24 ng, intact), 2-phenylethyl isothiocyanate (595.37 28.42 356.00 13.44 ng), undecane (771.44 34.72 1003.28 47.88 ng) methyl salicylate (1079.84 49.39 532.11 18.23 ng); among them, could attract adults. Our study suggests can be threat mono-cultivated B. schreberi, whereas damaged leaves may sacrifice themselves attracting herbivore-induced volatile, thus protecting whole plant population disturbance.
