Sex attractant for the banana moth, Opogona sacchari Bojer (Lepidoptera: Tineidae): provisional identification and field evaluation

Abstract

(E, Z)-2,13-octadecadienal has been identified as an attractant for O. sacchari males and can be used as a monitoring lure of populations of this moth.

Identification and field and laboratory tests of the sex pheromone of Cerconota anonella Sepp. (Lepidoptera: Oecophoridae)

“…Butler and McDonough (1981) found that the half-life of various moth pheromones loaded onto natural rubber septa (as used in the present study) increased significantly with the increasing number of carbon atoms in the molecule. In a study testing a C 18 aldehyde as a sex attractant for the banana moth, Opogona sacchari Bojer, the authors surmised that the bulk of 2E,13Z-18:Ald was not released from the septa during 2 weeks of field studies (Jang et al 2010). The ternary mixture tested here (9Z-18: Ac, 9Z-18:Ald and 9Z-18:OH) therefore was not likely to have evaporated during the 1-week period in which our field tests were performed.…”

Impact and management of Opogona sacchari (Bojer, 1856) (Lepidoptera: Tineidae) in a display glasshouse in the United Kingdom

“…To achieve these objectives, several pheromone traps have been installed across the tropical glasshouse (Figure 5) and the other two climatic zones to monitor for the presence of the moth. The sex pheromone is used to monitor numbers of adult male moths, but may also provide some level of control through mating disruption (Jang et al., 2010). Unlike the light traps, the pheromone traps do not need to be removed during the opening hours of the glasshouse, which has reduced potential disruption to visitors and the workload for staff.…”

Selection of Trichogramma species as potential natural enemies for the control of Opogona sacchari (Bojer)

“…It attacks all parts of the plant except for the roots and leaves (Davis and Peña, 1990). The larva penetrates the fruit and forms galleries, reducing its commercial value (Jang et al, 2010). O. sacchari is polyphagous and has been reported to attack coffee, pineapple, papaya, bamboo, corn, sugarcane, stored tubers, and ornamental plants .…”
