Nanoparticle Technology of Dodecenol As Active Components in © 2019 Subekti N, Et Al International Journal of VIBGYOR Nanoparticles and Nanotechnology Nanoparticle Technology of Dodecenol as Active Components in Cryptotermes Cynocephalus Control System Research Article: Open Access ISSN: 2631-5084 Niken Subekti1*, Ro’iyyatul Mar’ah1, Afrin Nur Aisyah1, Dina Fika Nada2 and Meidina Rahmawati2 1Biology Department, Universitas Negeri Semarang, Indonesia 2Chemistry Department, Universitas Negeri Semarang, Indonesia 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%.

This was in order to gauge the possibility of differentiating the species only on the basis of debris observation and analysis. Ten samples from six different geographical sources were analyzed and measured. Significant statistical differences were found between these two termite species in all measured parameters, and multivariate statistical models, able to predict species on the basis of dimensional measurements, were developed, with a degree of success higher than 75%. The most important dimensional differences were length and width, as well as the variable hexagonal shape of the cross-section of the detritic elements. The detritic elements of both species had a variable form of a hexagonal prism with slightly concave faces, and with pointed or rounded ends.

Yates III Department of Entomology, University of Hawaii, 3050 Maile Way, Honolulu, Hawaii 96822, USA Abstract: A termite survey of 18 coastal woodland localities on Oahu yielded five termite species including Neotermes connexus Snyder, Incisitermes immigrans (Snyder), Cryptotermes brevis (Walker), Cryptotermes cynocephalus Light, and Coptotermes formosanus Shiraki. The Indomalaysian and Australian species Cr. cynocephalus is reported in Hawaii for the first time and may have pest status there. The discovery of Cr. brevis colonies in a natural habitat is unprecedented and suggests that this popula- tion may either be related to prehistoric ancestors from the Neotropics or a new wood- land biotype which evolved from colonies introduced by humans. Keywords: termite, survey, Coptotermes, Incisitermes, Neotermes Introduction The termite fauna of the Hawaiian Islands was most recently reviewed by Bess (1970) who listed three species of drywood termites (Kalotermitidae) from Oahu including Neotermes connexus Snyder, Incisitermes immigrans (Snyder), and Cryptotermes brevis (Walker).
