Abstract

Contact and repellent toxicities of essential oil from Cnidium monnieri (L.) Cuss. (Apiales: Apiaceae) fruit on adults of Lasioderma serricorne (Fabricius) (Coleoptera: Anobiidae), and its ability to protect stored tobacco leaves from adult L. serricorne infestation were investigated. Essential oil from C. monnieri fruit had potent contact and repellent toxicities against adults of L. serricorne, and the contact and repellent activity increased significantly with increasing exposure time and dose. The greatest corrected mortality of contact toxicity bioassays killed 85.1% at 0.24 µl/cm2 at 72 hours of exposure. The greatest mean percentage repellency in repellent toxicity bioassays killed 93.5% of class V at 0.16 µl/cm2 at 48 hours of exposure. Essential oil of C. monnieri fruit substantially protected packaged flue-cured tobacco leaves from adult L. serricorne infestation. The number of L. serricorne was zero in flue-cured tobacco leaves packaged in kraft paper bags coated with essential oil of C. monnieri fruit at 0.04 µl/cm2 at 45 days. The results suggest that essential oil of C. monnieri fruit is a promising alternative to commonly used insecticides to control L. serricorne.

Se investigó el efecto por contacto y la repelencia del aceite esencial de frutos de Cnidium monnieri (L.) Cuss. (Apiales: Apiaceae) en adultos de Lasioderma serricorne (Fabricius) (Coleoptera: Anobiidae), así como la posibilidad de proteger hojas de tabaco almacenadas. El aceite esencial tuvo alta toxicidad y repelencia y ambas cualidades incrementaron al aumentar la dosis y el tiempo de exposición. La mayor mortalidad corregida y toxicidad por contacto fue 85.1% con 0.24 µl/cm2 y 72 horas de exposición. La mayor repelencia mató 93.5% de la clase V a 0.16 µl/cm2 y 48 h de exposición. El aceite esencial protegió el tabaco curado de la infestación de adultos de L. serricorne. El número de L. serricorne en hojas de tabaco curado en bolsas fue cero con la concentración de 0.04 µl/cm2 a los 45 días, lo que representa una alternativa a los insecticidas que se usan para el control de la plaga.
