“…Those larvae that were able to emerge into pupae could be due to level of internal resistance threshold developed by the pupae that survive. Thus, high mortality rate recorded by this extract could be due to the presence of monoterpenes listed above, which are hydrocarbons present in the extract that inhibits the developmental stages of insects (Peerzada, 1997;Azevedo et al, 2001;Miller et al, 2002).…”

“…H. suaveolens belongs to the family Laminaeceae and is a native of tropical America, but it is widespread in tropical Africa, Asia and Australia. It grows under a wide variety of soil and climate, mainly in warm area (Peerzada, 1997). Fresh stands of the species are found throughout the year at very high densities on old farmlands and along roadsides, particularly during the rainy season.…”

“…Citrus oil has a fresh odour and oil consistency and therefore has the potential for much wider use as larvicides against mosquito larvae. Moreover, H. suaveolens is known to be used for traditional medicine for treatment of various illnesses and the essential oil possess insecticidal and larvicidal properties (Peerzada, 1997). The present work was therefore, aimed at comparing the toxicity effects of Bush tea leaves and Orange peels oil extracts on the larvae of Ae.…”

Abstract:The ethanolic extracts of the orange peel (Citrus sinensis) and bush tea leaves (Hyptis suaveolens) were compared for their toxicity effect on the larvae of the yellow fever mosquito Aedes aegypti collected from disused tyres beside College of Natural Sciences building University of Agriculture, Abeokuta, Nigeria. Eight graded concentrations, 0.9ppm, 0.8ppm, 0.7ppm, 0.6ppm, 0.5ppm, 0.4ppm, 0.3ppm and 0.2ppm of both plant extracts were tested on the larvae. The mean lethal dose LD10, was 0.15 ppm for C. sinensis, 0.01 for H. suaveolens, while LD50 for C. sinensis was 0.4ppm, H.suaveolens 0.60ppm and LD90 for C. sinensis was 0.9ppm and H.suaveolens was 1.45ppm. LD10 for the control 0.65ppm, LD50 0.9ppm and LD90 2.0 ppm. The extract of C. sinensis peel caused higher mortality rate at concentrations 0.8ppm (95%) and 0.3ppm (90%) of the larvae while the extract of H. suaveolens caused high mortality rate on the larvae at concentrations of 0.9ppm (80%) and 0.3ppm (80%). Significant differences were observed between untreated and treated larvae (exposed to either of the extract) at the various concentrations (P< 0.05).

.A., and Onyali I.O., 2017, The larvicidal and repellent effect of bush mint plant (Hyptis suaveolens) and hairy sicklepod (Senna hirsuta) extracts against the larvae and adult of Culex quinquefasciatus, Journal of Mosquito Research, 7(8): 59-69 (doi: 10.5376/jmr.2017.07.0008) Abstract The efficacy of hexane leaf extracts of Hyptissuaveolens and Senna hirsuta as a larvicide and repellent against the 4 th instar larvae and adult of Culexquinquefasciatus was investigated. Extraction was done using Soxhlet apparatus. Twenty fourth instar larvae of Culexquinquefasciatus were exposed to various concentrations (5%, 10%, 15%, 20%, 30% and control) and observed over 3 hours for mortality. Repellency against the adult mosquito was investigated on five human volunteers who did not use any lotion, soap or perfume on the arm. The experiment was carried out during the day in a dark shade. Percentage repellence was recorded every 10minutes for a period of 1 hour. Lethal concentration 50% (LC 50 ) which is the concentration required to kill half the members of the tested population after 3 hours of exposure was used to assess the larval mortality. Result indicated the combined extract with LC 50 6% gave a higher mortality than the individual extract of Hyptis suaveolens (LC 50 6.4%) and Senna hirsuta (LC 50 7.5%). Similarly, repellence was highest in the combined extract with 75% repellency than in the extracts of Hyptis suaveolens (70%) and Senna hirsuta (50%). The result observed in the study was analyzed using Analysis of Variance. There was a significant difference from the use of individual extracts (P< 0.05). From the result of the study, it was deduced that the efficacy of the treatments increased with an increasing exposure time and concentration. The findings of the study revealed the efficacy of hexane leaf extracts of Hyptis suaveolens and Senna hirsuta as good larvicide and repellent against Culex quinquefasciatus especially in the synergistic state.

“…The plant is native to Tropical America, but is now spread all over the world, especially in the tropical area. 1 The genus Hyptis has been found to possess significant pharmacological activities, including tumorigenic, antifertility, mycotoxic and phototoxic activities. 1 H. suaveolens has also been reported recently to possess insecticidal activity.…”

The essential oils of the leaves of Hyptis suaveolens (L.) Poit collected from two different sources were isolated by hydrodistillation. The oils were analysed by GC and GC-MS; 36 constituents were identified in the oil of sample collected from the campus of Lagos State University (LASU), while 33 constituents were identified in the oil of sample from Obafemi Awolowo University (OAU). α α α α α-Pinene (13.6%), sabinene (13.2%), p-cymene (11.7%), terpinen-4-ol (9.8%) and terpinolene (6.3%) were the major monoterpenes in the LASU oil sample, while sabinene (30.0%), terpinen-4-ol (11.4%), terpinolene (5.6%), 1,8-cineole (5.2%), β β β β β-pinene (4.4%) and α α α α α-terpinene (4.2%) were the main monoterpenes in the OAU oil sample. β β β β β-caryophyllene (5.1-5.9%) and trans-α α α α α-bergamotene (1.6-5.2%) represented the major sesquiterpenes in both oils.
