Insecticidal activities and repellent effects of methylcinnamate and essential oils from Alpinia galangal against nymphs and adults of Metcalfa pruinosa
Journal of Applied Biological Chemistry
Metcalfa pruinosa is a pest causing widespread problems to many crops in Korea. This pest infects fruit crops especially, persimmon and grapes. We tested the possibility of M. pruinosa management using essential oils of Alpina galangal and methylcinnamate which were extracted from A. galangal by steam distillation method. The use of essential oil showed a mortality rate of 10.0 and 23.3% for adults and nymphs, respectively. While the use of methylcinnamate resulted to a mortality rate of 40.0%doi:10.3839/jabc.2018.041 fatcat:liib5yadxrah3bzm7qsgdtwzgi
