Abstract

The first effort to conserve bats is to understand food preference factor. The aim of the research was to investigate type of plant species eaten by bats and the bats food preferences, including flower corolla, pollen type and pollen dimension. Method used in this study was identification of pollens eaten by the bats using pollen analysis. The study revealed that based on preferences, corolla factor affected bat species that fed on them. Male of Cynopterus titthaecheilus Temminck and male of Eonycteris spelaea Dobson were attracted to stellatus. Female of C. titthaecheilus was attracted to disk, while male of Cynopterus brachyotis Müller, male of Macroglossus sobrinus K. Andersen, and female of E. spelaea were attracted to papilionaceus, tubulosus, and stellatus. Female of Cynopterus minutus Miller and Cynopterus sphinx Vahl were attracted to campanulatus and inflorescences. Female of C. brachyotis was attracted to inflorescences and urceolatus. Pollen types affected bats species, male of C. titthaecheilus was attracted to suboblate. Male of C. brachyotis, male of M. Sobrinus, and female of E. spelaea were attracted to prolate spheroidal, while female of C. titthaecheilus was attracted to oblate. Male of C. brachyotis was attracted to peroblate and prolate, while male of M. sobrinus and female of C. minutus were attracted to perprolate. Female of C. minutus was attracted to perprolate and suboblate. Size of pollen gigantea and magna affected male of C. brachyotis, C. Titthaecheilus, and M. sobrinus; and female of E. spelaea while permagnae showed weak effect on bats.
