Anti-termite activities of Indonesia’s essential oils against invasive drywood termite for wood product protection

Abstract

The Indo-Malayan drywood termite, Cryptotermes cynocephalus (Light) (Kalotermitidae), is considered one of the most invasive drywood termites in the Southeast Asian region. Once infesting a timber, the colony of a drywood termite is very difficult to be controlled. Thus, the best way to mitigate a new infestation of a drywood termite is by applying chemical protection on wood. In recent years, particular attention has been given by researchers to develop and use organic termiticides, such as essential oils extracted from plants as active ingredients. The objective of the present study is to evaluate the repellency performance of several economically important essential oils from Indonesia, such as Clove (Eugenia caryophyllata), Cubeb Pepper (Piper cubeba L), and Lemon Grass (Cymbopogon winterianus Jowitt) against a drywood termite, C. cynocephalus. The test was performed by subjecting various concentrations of essential oil toward C. cynocephalus in the force-feeding test method. Sample weight-loss was evaluated after two weeks test. The results suggested that Clove oil has the highest repellence performance against C. cynocephalus, followed by Lemon Grass and Cubeb Pepper oils. The Termite mortality rate was also recorded to understand the toxicity performance of those essential oils.

Termiticidal and Biochemical Activity of Combinatorial Essential Oil Ingredients of <i>Tagetes erecta</i> on Indian White Termite <i>Odontotermes obesus</i>

“…Basic oils and ethanolic extricate from C. konishii, and their viable constituents, served as potential, eco-friendly termite-control agent [46]. Essential oils from Clove (Eugenia caryophyllata), Cubeb Pepper (Piper cubeba L), and Lemon Grass (Cymbopogon winterianus Jowitt) shows highest repellency performance against Cryptotermes cynocephalus (Kalotermitidae) [47]. Plant essential oils from Corymbia citriodora, Croton sonderianus, Cymbopogon martini, Lippia alba, L. Gracilis, L. Sidoides and Pogostemon cablin shows repellent activity on N. Corniger [48].…”

Anti-termite Activity of Tamanu Bark Extract (Calophyllum inophyllum L.)

“…Vittaya et al (2023) noted that the n-hexane extract obtained from C. inophyllum flowers comprises terpene compounds like monoterpenes, sesquiterpenes, and triterpenes. Several terpene compounds, including those from the monoterpene and sesquiterpene classes, have been reported to possess antitermite activity (Meisyara et al, 2021). Friedelan-3-one has been associated with various biological activities.…”

“…2). Rubberwood (Hevea brasiliensis) sample was used as a control (Ismayati et al 2011;Meisyara et al 2021;Tarmadi et al 2014). The forced-feeding test was conducted for 3 weeks and incubated under dark conditions at 28C and 70% humidity.…”

“…Sterilized CBP specimens were inserted into the jars aseptically and then incubated at room temperature for 12 weeks. Rubberwood block was used as a control (Ismayati et al 2011;Meisyara et al 2021;Tarmadi et al 2014). This test used nine replicates.…”
