International working conference on stored product protection
Se adjunta el abstract de la comunicación oral. Como se puede ver está directamente relacionado con el proyecto de investigación en el que participa la solicitante. El objetivo de la asistencia al congreso es divulgar algunos resultados obtenidos: por ejemplo que si combinamos el "vacio a baja presión" con "monoterpenoides" se puede reducir el tiempo requerido para matar a las plagas de cereal en almacén.
Además se aprovechará el congreso para que tenga lugar una reunión de proyecto.
Abstract
Monoterpeniods as well as low pressure simulating vacuum, when applied alone have been demonstrated to cause mortality of stored-product insect pests. The current report explored the possibility of integrating these two control methods in the management of stored-product insects. The insects used for this study were the adults of the red flour beetle, Tribolium castaneum, and diapausing larvae of the Indianmeal moth, Plodia interpunctella.
The monoterpenoids investigated were E-anethole, estragole, S-carvone, linalool, L-fenchone, geraniol, γ-terpinene and DL-camphor. Exposure of the insects to all the monoterpenoids alone, with the exception of camphor, at a concentration of 66.7µL/1L of volume required more than 48 h to generate 100% mortality at 28.0 ± 0.8°C. However, exposure of the insects to camphor alone generated 100% mortality with 1 h exposure.
Exposure of the insects to low pressure at 32.5 mm Hg generated 100% mortality in beetles with 24h exposure and in the diapausing P. interpunctella larvae with 48 h exposure. However, combination of the monoterpeniods with low pressure reduced exposure periods required to generate 100% mortality in both diapausing larvae of P. interpunctella and the adult beetles of T. castaneum to 12 h. In all cases T. castaneum showed signs of weakness faster than diapausing P. interpunctella larvae.
