Dry wood termites attack is one of the problems that cause huge losses in timber construction. One way to solve this problem is by preserving wood, with synthetic chemicals or natural ingredients. The purpose of this preliminary research was to determine the effect of ironwood powder extract as a natural wood preservative. Preservation methods conducted were cold immersion at normal temperature (± 25°C) and hot immersion at 80°C. Variations in the concentration are 5%, 10%, 15%, and 20%. Variation of immersion time are 1, 2, and 3 days for the cold immersion and 0.5; 1; 2; 3 hours for the hot immersion. Results show that mortality data and the degree of attack of dry wood termites. The results showed that the mortality of the dry wood termites increased 4−6%. However, no difference was found on the degree of attacks between preserved and control wood.

“…The list of active substances is not closed, because Regulation EU 528/2012 provides the opportunity to conduct scientific research in the selection of new active substances with high fungicidal effectiveness and a guaranteed level of toxicological and eco-toxicological safety. Bearing in mind the safety in the use of biocides, research is being carried out to assess the fungicidal activity of substances of natural origin, such as plant extracts, alkaloids, essential oils, but also substances produced by microorganisms (Kundzewicz and Ważny 1994;Cofta et al 2014;Adedeji et al 2017). Many substances of natural origin in fact have fungicidal activity, which was confirmed from in vitro tests (Barbero-López et al 2018).…”

The results of the post-culture fungicidal medium from Trichoderma viride Pers. and Alternaria alternata (Fr.) Keissl. mold fungi and Acetobacter xylinum bacteria were studied relative to selected fungi belonging to Basidiomycetes, which cause wood decay. The obtained results confirmed that post-culture liquids derived from the cultivation of various microorganisms might have a differentiated fungicidal effect on wood-decaying fungi. The lowest concentration of fluid from A. xylinum culture added to the growth medium of the studied fungi that completely inhibited the growth was 5mL/100mL.The fungicidal effect of the liquid from the mold fungus culture on the tested wood-decaying fungi turned out to be definitely low. Trametes versicolor (L.) Lloyd proved to be the most sensitive species. Pleurotus cornucopiae (Paulet) Rolland showed complete resistance to the liquid added to the growth medium, derived from mold fungi. The A. xylinum bacterial culture-fluid may be subject to further analysis as a natural biocide in protecting wood against wood-decaying fungi.

“…Bioactive compounds from different plants that are cheaper, target-specific, biodegradable and non-toxic to humans can be used to replace synthetic insecticides [11]. Plant-derived biocides are naturally occurring compounds in roots, leaves, heartwood and bark, where they act as a defensive agent against xylophagous insects [12]. Termiticidal compounds like 2-methyl-9,10-anthracenedione, 1-methyl-3,4-dihydroisoquinoline and squalene have been reported to be present in the heartwood of Tectona grandis [8].…”

The subterranean termites Odontotermes obesus and Heterotermes indicola are highly infesting wood pests that cause economic losses that cost billions of dollars throughout the world -especially in tropical and subtropical regions. It is highly significant to formulate insecticides from plant-based chemicals rather than synthetic ones. The eight plant species resistant to termites were selected for screening as anti-termite phytochemicals. Extracts from different parts of the plants were collected by using ethanol solvents in different ratios. These extracts were evaluated for their toxicity against termites and their gut flagellates at subsequent concentrations in the range of 100-2000 ppm to find LC 50. Although the plants tested were found to be effective, extract from Grevillea robusta showed maximum mortality and reduced termite survival rate to 94% (LC 50 = 1391.01) and 90% (LC 50 = 1607.95) of O. obesus and H. indicola respectively. This extract also reduced the survival rate of hindgut flagellates of H. indicola up to 95% with an LC 50 value of 502.64 ppm. The extract of Grevillea robusta was characterized by UV-Vis spectroscopy, FTIR and GC-MS analysis. Two absorption peaks were recorded by UV-Vis spectroscopy at 208.94 and 282.97nm having absorption of 2.33 and 0.811 respectively. FTIR analysis confirmed the presence of amines, alcohols, alkanes, nitriles, aldehydes, ether and halo compounds. GC-MS analysis revealed the presence of 15 phytochemicals with a high percentage of Coumarin (30.64%), 7-hydroxy, Methyl hexofuranoside (27.63%) and 9,12,15-Octadecatrienoic acid *No-choice bioassay [20] was designed to evaluate the toxic potential of plant extract against two species of termites: O. obesus and H. indicola. Whatman (Z,Z,Z) (8.97%). The natural phytochemicals from G. robusta having termiticidal and protozocidal potential being eco-friendly can replace synthetic pesticides for termite control.
