Calatayud, P.A., Auger, J., Thibout, E., Rousset, S., Caicedo, A.M., Calatayud, S., Buschmann, H., Guillaud, J., Mandon, N., & Bellotti, A.C. 2001 Identification and synthesis of a kairomone mediating host location by two parasitoid species of the cassava mealybug Phenacoccus herreni.. Journal of Chemical Ecology 27(11): 2203-2217.

Notes: Two encyrtid species, Acerophagus coccois and Aenasius vexans, parasitoids of the cassava mealybug Phenacoccus herreni use a contact kairomone from the body surface of their host as a host-location stimulant. The kairomone was synthesized and identified as O-caffeoylserine based on a combination of chromatographic methods. The synthetic compound was determined to be active.
