Borassus flabellifer
The list of known hosts includes: "Areca catechu", "Arenga pinnata", "Borassus flabellifer", "Caryota maxima", "C. cumingii", "Cocos nucifera" (coconut palm), "Corypha gebanga", "C. elata", "Elaeis guineensis", "Livistona decipiens", "Metroxylon sagu", "Oreodoxa regia", "Phoenix canariensis", "P. dactylifera" (date palm), "P. sylvestris", "Sabal umbraculifera", "Trachycarpus fortunei", "Washingtonia" spp. Lab studies have reared the insect on diets of "Agave americana" and "Saccharum officinarum", but these findings have not been observed in the wild. There is evidence that the weevil prefers the 'Sukkary' cultivar of date palm to other cultivars.
