Nanoparticle Technology of Dodecenol as Active Components in Cryptotermes Cynocephalus Control System

Abstract

Cryptotermes cynocephalus is one of the Kalotermitidae species. In Indonesia, this species is known as wood-destroying pest. Damages incurred economic losses up to billions of rupiah per year. One of the technologies that can be used for controlling is nanotechnology of dodecenol pheromones. This study aims to analyze the effectiveness of nanoparticle pheromone dodecenol from Body Extract (BE) and Sternal Gland Extract (SGE) for controlling Cryptotermes cynocephalus through termite feeding preference and analysis of chemical components of both. Both extracts were analyzed using GC-MS then tested bios assay Y to compare its effect on feeding behavior of termites. BE was then used as a main material to produce nanoparticle gel. The food-preference test was conducted using Petri dish assay and endurance test based on Indonesian National Standard 2006. Petridis assay and endurance test in this research used 6 treatment of dodecenol nanoparticle concentration (0%, 5%, 10%, 15%, 20%, and 25%) and 3 repetitions. The GC-MS chromatogram results show that in the termite extract there are dodecenol compounds. Bioassay Y test showed that there was a difference between BE and SGE effect on termite adaptation and termite (P < 0.05). The bioassay choice test of Y shows that there is a difference in the effect of BE with SGE on the behavior of termites. BE is more influential than SGE with a significance level of 5%. Petridis assay shows that nanoparticle 10% maximally increases termite preference to pine wood sample indicated by mass loss 13.856%.
