“…The estimate of total Cerambycidae richness suggested by the species accumulation curve may be relevant only to the subset of species that would be caught by Malaise trapping as adults, in a forest habitat, at ground level. This suggestion is given some support by comparison with the species collected by Waqa-Sakiti et al (2014) on Viti Levu by rearing from rotting timber. Although there is some uncertainty due to both studies collecting new/undescribed species, of the eighteen Cerambycidae types obtained in the previous study at least eight were not recorded by Malaise trapping in the current study, and 11 (61%) were not captured during the three Malaise trapping events on Viti Levu.…”

The study by Waqa-Sakiti et al (2014) also highlighted seasonal differences in species occurrence and relative abundance. Although sampling in the current study was active over most months of the year, there was no single location that was studied continuously over a 12 month period to give a higher chance of recording species with narrow adult flight periods (Tikoca et al 2016b).…”

“…Lingafelter (2007) has since described two new species of the genus Distenia from Fiji, whilst Waqa and Lingafelter (2009) reviewed the tribe Callidiopini and Waqa-Sakiti et al (2015) reviewed the genus Ceresium. In terms of ecology of the group, Waqa-Sakiti et al (2014) reported information on the species of trees used as hosts by 18 species of Cerambycidae on Viti Levu by rearing larvae from timber baits. Fiji has a high level of endemic species for the Family Cerambycidae with an estimate of 88% endemism (Dillon and Dillon 1952).…”

Long-horn beetles (Family: Cerambycidae) in Fiji consist of 124 described species within 45 genera, of which 110 (88.7%) species are considered endemic. Despite their conservation value, ecological significance and cultural importance, little scientific research has been conducted on the taxonomy or ecology of Cerambycidae in Fiji. This biogeographical study surveyed Cerambycidae by Malaise trapping on ten Fijian Islands. A total of 438 individuals and 44 species of Cerambycidae were recorded. Thirty three of the species collected are endemic to Fiji; three other species are native and eight species are new records for Fiji and/or new species. Twenty seven species were recorded from only one island and 20 species were recorded only as singletons. There was an expected significant relationship between the number of species collected on an island and the number of sampling events. The highest number of species, 23, was recorded on the largest island, Viti Levu, followed by Gau with 13 species and Vanua Levu and Kadavu with 12 species each. There was a positive relationship between species richness and island size but this was lost if the effect of sample number was taken into account. The results indicate that the species-area relationship may hold for Fijian Cerambycidae, but additional collecting events, over more of the annual cycle, and involving multiple collecting methods may be required to fully catalogue the current Fijian fauna.

Some species have been found in Schima woods i.e., Psephactus scabripennis, Ceresium signaticolle, Xylotrechus ogasawarensis, Chlorophorus boninensis, and C. kobayashii (Sugiura et al 2008); and in Agathis woods i.e., Sormida cinerea (Waqa-Sakiti et al 2014). 8 The highest diversity of longhorn beetles was found in the natural forest, followed in order by the pine forest, the mixed forest, the Schima forest, and the Agathis forest.…”

“…Different species of longhorn beetle will choose different species of tree or shrub (Sakenin et al 2011). Some species of longhorn beetle live only in specific host plants, while other species can inhabit a variety of plants (Waqa-Sakiti et al 2014). The longhorn beetle's life depends on the presence of trees, and it can therefore be used as an indicator of the condition of a forest (Ohsawa 2010;Noerdjito 2011;Lachat et al 2012).…”

Gunung Walat Educational Forest is located at an altitude of 500-700 m asl and has a variety of forest types. This research investigated the diversity and abundance of longhorn beetles found in several types of plantation forest. The beetles were collected using Artocarpus traps in September and October 2014. Sixteen species of longhorn beetle were found; these belonged to 7 tribes and 12 genera. The highest diversity and evenness of longhorn beetles were found in the natural forest (H=1.80, E=0.75) and the lowest of both measures in the Agathis forest (H=0.556, E=0.232). The highest similarity index (0.75) was found between the natural forest and the pine forest. Five of the species found, i.e. Sybra binotata, Sybra fuscotriangularis, Ropica strandi, Acalolepta rusticatrix, and Pterolophia melanura were highly abundant. Two of these, R. strandi and S. fuscotriangularis, as well as 4 other species found, Cleptometopus montanus, Myagrus javanicus, Notomulciber notatus, and Exocentrus artocarpi, are only found in Java. Finding Ropica marmorata was the first such record of this species on the island of Java.

Host specificity and association of Cerambycidae with the physical characteristics of the wood of trees in a tropical dry forest

et al. 2023

Few studies test the host specificity of tropical dry forest cerambycids, in this study, we examined the host preferences of the cerambycids of a tropical dry forest in central Mexico and the association of cerambycid richness and abundance with the physical characteristics of the wood of their host plants. Branch segments of 81 species of woody plants were cut and left exposed to allow cerambycids oviposition, and the branches were collected and placed in emergence chambers. We measured the density, decomposition rate, and volume of wood for each branch segment. Fifty‐seven species of cerambycids emerged. We categorized the cerambycids by the degree of host specificity: 23% were generalists, 14% were specialists, and for 63% of the data were insufficient to determine specificity. For the first time we report, for the tropical dry forest, preference patterns between Cerambycidae (subfamilies and species) and their host plants (families and species). Physical characteristics of wood, such as density and decomposition rate, were strongly related to the presence of cerambycids. Cerambycidae in this forest use wood resources that decompose at an intermediate rate and are relatively soft. The cerambycids were most often generalists, and specific cerambycid/tree species associations were rare, but close commensal relationships were found at the level of subfamilies and plant families. Cerambycid richness and abundance depend on the type of host, medium decomposed woods, and the great abundance of each individual host in the area.
