A single compound that elicited an electrophysiological response from conspecific male antennae was isolated from volatiles emitted by adult females of the aerial root mealybug, Pseudococcus baliteus. Mass spectrometry and nuclear resonance spectroscopy analyses, as well as enantioselective syntheses, revealed the structure to be 2-((S)-1,2,2-trimethyl-3-cyclopentenyl)-2-oxoethyl (S)-2-methylbutyrate. This ester, which is a hitherto-unknown monoterpene with an α-hydroxyketone moiety, displayed attractiveness to adult males and was concluded to be the P. baliteus sex pheromone.

气生根粉虱(Pseudococcus baliteus)的性信息素:含有α-羟基酮部分的独特单萜
从气生根粉虱(Peseudococcus baliteus)成年雌性释放的挥发物中分离出一种从同种雄性触角引起电生理反应的单一化合物。质谱和核共振光谱分析以及对映选择性合成显示该结构为2-((S)-1,2,2-三甲基-3-环戊烯基)-2-氧代乙基(S)-2-甲基丁酸酯。此酯,其是迄今未知的单萜与α羟基酮部分,显示吸引力成年男性和得出的结论是P。黄褐斑性信息素。
