“…Umumnya tiga spesies rayap dari genus Coptotermes yang sering ditemukan sebagai hama pada perkebunan kelapa sawit di lahan gambut adalah C. curvignathus, C. borneensis, dan C. sepangensis. Spesies C. curvignathus teridentifikasi sebagai hama utama yang sangat agresif dalam merusak jaringan hidup pada tanaman sawit (Yii et al, 2016).…”

The termite Coptotermes curvignathus is an important pest in oil palm plantations and environmentally friendly control measures are needed. The fungus Aspergillus spp. has potential as a biocontrol agent against the termite C. curvignathus. The purpose of this study aimed to obtain Aspergillus spp. which are virulent against C. curvignathus. Aspergillus spp. isolates used in this study were collected from termite nests in the primary forest at Suaq Balimbing Research Station, Gunung Leuser National Park, Sumatra. This study used an experimental method with a completely randomized design (CRD). Two isolates of Aspergillus spp. each 105 conidia/mL were applied to worker caste termites. The results of the virulence assay showed that isolate Aspergillus sp. 1 had the highest causing 82.13% mortality of C.curvignathus and with an LT50 value of 4.18 days.

“…Meanwhile, Rhinotermidae was the second largest family after Formicidae. Formicidae and termites are two groups of soil fauna that dominantly inhibit peat soil [36][37][38]. Formicidae are a group of insects that is commonly distributed alm ost in everyplace and have characteristics to adapt in varies types of peat soil [6] .…”

Most studies mentioned that Acacia crassicarpa belongs to invasive species that could threat the native biodiversity. To respond that issue, we conducted a study that covers the understory and soil macrofauna diversity of three native tree species, namely mahang (Macaranga pruinosa), skubung (Macaranga gigantea) and geronggang (Cratoxylum arborescens) and an exotic species namely krassikarpa in a drained peatland in Pelalawan, Riau. The observation of understory vegetation under each studied species was undertaken by using 2 x 1 m plots. Furthermore, the structure of macrofauna was observed by pitfall trap methods. Results revealed that there were two fern species namely Neprolephis biserrata and Stenochlaena palustris that dominated the understory vegetation in namely mahang (Macaranga pruinosa), skubung (Macaranga gigantea) and geronggang (Cratoxylum arborescens). The diversity index in vegetation structure among those four tree species was insignificantly varied. Moreover, the percentage of understory coverage under A. crassicarpa was significantly higher than that under all native tree species. On the other hand, Formicidae and Rhinotermitidae were dominant in skubung and krassikarpa. Meanwhile, Formicidae and Blattidae were high in mahang and geronggang. Furthermore, diversity index of macrofauna were significantly low at krassikarpas`s understory compare to other three native species. This study suggested that the introduction of krassikarpa affect the biodiversity.

“…However, the results of further analysis using Tukey pairwise comparisons between the exposure periods and weight loss revealed that the weight loss obtained from each exposure period was relatively indifferent at the 5% significance level. Yii et al (2016) stated that termite feeding preference is significantly affected by the sizes of bait, and that the consumption of rubber wood sawdust is 4 times higher than the block form. The value of the pin penetration depth moved upwards along with increases in the exposure period (Table 2).…”

The pattern of termite infestation was investigated in structural lumber, light Red Meranti (Shorea spp.), using a minimally destructive technique. The relationship between the visual inspection and the pin penetration approach in predicting the basic properties of wood was determined, and a pin penetration distribution value was mapped into a contour map based on the Kriging interpolation technique. Small wood block samples were exposed to reared subterranean termites Coptotermes curvignathus Holmgren (Isoptera: Rhinotermitidae). The characteristics of termite infestation and the changes in the physical-mechanical properties were investigated. The residual surface area of the samples was evaluated using Pilodyn®. The characteristics of the termite galleries found on small wood block samples were as follows: 1) the termite galleries varied in length, or 2) the galleries consisted of long flat tunnels in a longitudinal direction, clean, not decayed, and contained no soil residue. The weight loss percentage from this study exhibited a similar trend with the pin penetration depth, which was directly proportional to the exposure period. The pin penetration result from Pilodyn® generated distribution map that was represented the conditions and basic mechanical properties of the samples. Pilodyn® can be used a complement for visual inspection in in-situ assessment.
