摘要
The insect populations of a botanicals warehouse in north-central Florida were studied to gain a better understanding of insect problems associated with stored botanicals and to identify measures that could be taken to mitigate the problems. The warehouse contained either dried saw palmetto berries, Serenoa repens (Bartram) Small, or dried passion-flower (maypop) vines, Passiflora incarnata (L.), depending on the season. Insect populations were monitored intermittently for one year using arrays of moth and beetle traps. Capture rate, relative abundance, and spatial distribution of different species were examined over time. The six most abundant species in order of abundance were: Cadra cautella (Walker), Lasioderma serricorne (F.), Oryzaephilus mercator (Fauvel), Typhaea stercorea(L.), Plodia interpunctella (Hubner), and Tribolium castaneum (Herbst). All of these appear capable of infesting saw palmetto, but the major pests were C. cautella and L. serricorne. Oryzaephilus mercator and P. interpunetella were also important, but T. castaneum and T. stereorea were minor. Passion-flower was a less suitable host than saw palmetto for all of the species except T. stercorea. Nevertheless, all of the six species infesting saw palmetto except O. mercator were captured in numbers sufficient to indicate that they were also capable of infesting passionflower. Lasioderma serricorne was the major pest. Spatial analysis of trap captures revealed that the insect distributions changed as different botanicals were brought in, removed, or redistributed in the storage area. Potential measures to mitigate insect problems in stored botanicals are discussed, including spatial targeting of insect control and sanitation efforts. Published by Elsevier Science Ltd.
