Item type:Publication, Adulticidal activities of Cymbopogon citratus (Stapf.) and Eucalyptus globulus (Labill.) essential oils and of their synergistic combinations against Aedes aegypti (L.), Aedes albopictus (Skuse), and Musca domestica (L.)(2020-06-01); Sittichok, SirawutThe knockdown and adulticidal activities of individual Cymbopogon citratus and Eucalyptus globulus essential oils (EOs) and their combinations were evaluated against three medical insect pests (Aedes aegypti, Aedes albopictus, and Musca domestica) using a WHO susceptibility test. The knockdown and adulticidal activities against the three medical insect pests of combinations of C. citratus and E. globulus EOs were higher than those of individual EOs alone. Combinations of 7.5% C. citratus + 7.5% E. globulus EOs and 10% C. citratus + 10% E. globulus EOs exhibited the highest efficacy against females of the three species with 100% knockdown and mortality rates at 1 and 24 h after exposure, respectively. Their adulticidal activities were equivalent to that of 10% w/v cypermethrin. In contrast, 70% v/v ethyl alcohol negative control was not effective at all. The combinations of EOs showed a synergistic effect, i.e., their adulticidal activity was improved by 0.2 to 100%, with increased knockdown and mortality rates, compared to individual EOs. The highest synergistic effect on effective knockdown and adulticidal activities against females of the three species was achieved by a combination of 2.5% C. citratus + 2.5% E. globulus EOs, with 36.6 to 100% knockdown rate increase and 33.5 to 98.9% mortality rate increase. This study demonstrates that all tested combinations of C. citratus and E. globulus EOs were effective adulticidal agents against females of Ae. aegypti, Ae. albopictus, and M. domestica and have a high potential for development into a botanical insecticide for controlling populations of Aedes mosquitoes and houseflies. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Insecticidal synergy of essential oils from Cymbopogon citratus (Stapf.), Myristica fragrans (Houtt.), and Illicium verum Hook. f. and their major active constituents(2021-06-01); Sittichok, SirawutThis study attempted to find safe and effective green insecticidal agents against Musca domestica L., which is a major public health pest in tropical and subtropical countries that have already developed resistance to synthetic pesticides. Plant essential oil-based insecticides are new, effective, and eco-friendly alternatives. Today, they are a housefly control method of choice. The study evaluated the insecticidal effect against M. domestica adults of essential oils (EOs) from Cymbopogon citratus (Stapf.), Illicium verum Hook. f., and Myristica fragrans (Houtt.) as well as their major active chemical constituents. Formulations of these individual and combined compounds were evaluated to see whether they were synergistic against M. domestica. Chemical compositions of these EOs were also analyzed by GC–MS. The major constituent of C. citratus was found to be geranial (45.4 %); that of I. verum was trans-anethole (94.0 %), and that of M. fragrans was α-pinene (21.6 %). Formulation CB3 (0.5 % I. verum EO + 0.5 % geranial) exhibited the highest synergistic effect (SI = 0.04), with 100 % knockdown and mortality rates, a 50 % knockdown time (KT<inf>50</inf>) of 4.0 min, and a 50 % lethal time (LT<inf>50</inf>) of 6.0 min. CB3 was more effective than 1% w/v cypermethrin, followed by CB5 (0.5 % M. fragrans EO + 0.5 % geranial), CB7 (0.5 % α-pinene + 0.5 % geranial), and CB8 (0.5 % geranial + 0.5 % trans-anethole). To conclude, some formulations of combined C. citratus, I. verum, and M. fragrans were strongly synergistic against M. domestica and more effective than cypermethrin. Moreover, since they have been long used as natural food ingredients and in traditional medicine, they are also safe for humans, non-target organisms, and the environment. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Binary Mixtures of Essential Oils: Potent Housefly Adulticides That Are Safe Against Non-Target Species(2025-08-01); ; Murata, KouheiIn this study, we investigated the insecticidal potential of Eucalyptus globulus Labill. and Cymbopogon citratus Stapf essential oils (EOs), both alone and in synergistic blends with their primary active compounds, against adult houseflies (Musca domestica L.). Toxicity assessments were also conducted on non-target organisms—dwarf honeybees (Apis florea Fabricius) and guppies (Poecilia reticulata Peters)—to evaluate environmental safety. All binary EO mixtures demonstrated superior efficacy compared to individual EOs and the synthetic pyrethroid α-cypermethrin (1% positive control). The most potent formulation, combining 2.5% (v/v) geranial with 2.5% (v/v) E. globulus EO, exhibited a synergistic effect, achieving complete fly mortality (LT<inf>50</inf>: 0.06 h). This mixture’s mortality index significantly exceeded those of single-component formulations, with a mortality index of 0.22, confirming greater toxicity to flies than α-cypermethrin. Importantly, all the tested EOs and their blends were non-toxic to honeybees and guppies; in comparison, α-cypermethrin caused significant harm. These findings highlight the 2.5% (v/v) geranial + 2.5% (v/v) E. globulus EO blend as a highly effective and environmentally friendly alternative to conventional insecticides. Further research is recommended to optimize its formulation for practical use in sustainable fly management. - Some of the metrics are blocked by yourconsent settings
