“…The study indicated that PPRC-44BC and PPRC-27J isolates showed promising results causing lower median lethal time (LT 50 ). The lifecycle study indicated that the average longevity, for the female and male bugs was 187±7.8 and 135±10 days, respectively [27]. PPRC-44BC and PPRC-27J isolates showed complete mortality after 18 th and 21 st days of isolates application, respectively.…”

Antestia bug (Antestiopsis intricata) is the major coffee insect pest affecting coffee productions in Ethiopia.Therefore, the study was carried out to evaluate entomopathogenic fungi based management options for antestia bug control. The efficacy test of entomopathogenic fungi was done under laboratory condition in Jimma Agricultural Research Center, Entomology and Pathology laboratories. The entomopathogenic fungi isolates were brought from Haramaya University and Ambo Agricultural Research Center. Seven isolates of Beauvaria bassiana (DLCO-12, APPRC-0247, DLCO-90, DLCO-56, DLCO-76, PPRC-44BC, and PPRC-27J) and four isolates of Metarhizium ansopliae (PPRC-51, DLCO23A, DLCO-91 and PPRC-02BC) species were tested for germination. Completely Randomized Design with three replications and probit analysis were used for data analysis by using SAS, GenStat and Microsoft excel. Eight isolates: APPRC 0247, DLCO 90, DLCO 56, DLCO 76, PPRC-44BC, PPRC-27J, PPRC-51 and PPRC-02BC which recorded higher germination were used for pathogenicity test against antestia bugs. All the tested isolates killed antestia bugs but their levels of efficacy differ across exposure time. Among tested isolates, PPRC-44BC and PPRC-27J registered complete mortality against antestia bugs and lower median lethal time, LT 50 (9.98 and 10.98 days, respectively). As a result these were taken as promising isolates and used for further isolates rate test. PPRC-44BC and PPRC-27J isolates applied at 1x10 8 conidia ml -1 killed all the tested antestia bugs in shorter exposure time. Even though PPRC-44BC and PPRC-27J isolates showed promising results under laboratory conditions, it needs further investigations on its formulation and under field conditions. Isolations of biocontrols from natural coffee growing areas and the effect of biocontrols against natural enemies should be studied.

“…Essential oils are well-known for their bioactivities, e.g., antimicrobial and antioxidant, and have long been used in different traditional medicine systems as well as in modern medicine, cosmetics, and pharmaceutical products [ 29 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 ]. Their applications as an insecticidal, larvicidal, nematocidal, pesticidal, phytotoxic, and insect-repellent agents are also well-documented [ 93 , 94 , 95 , 96 , 97 , 98 , 99 , 100 , 101 , 102 , 103 , 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 , 114 , 115 , 116 ]. Ruta essential oils found their way into various traditional medicinal products, and a significant body of literature could establish their bioactivities and medicinal potential [ 4 ].…”

“…Plant essential oils are known to have insecticidal properties and have been employed in ecologically-friendly agricultural operations, including the control of pest insects of stored agricultural products [ 103 ]. Ruta essential oils are no exception and have been shown to possess insecticidal activity against various insect species, and have been proposed as natural and eco-friendly insecticides with the potential for replacing harmful conventional insecticides.…”

“…The essential oil of the aerial parts of R. chalepensis exhibited significant insecticidal activity against three major pests, coffee berry borer (also known as coffee borer beetle; Hypothenemus hampei ; 82.5% mortality in 24 h), antestia bug ( Antestiopsis sp. ; 87.5% in 24 h), and maize weevil ( Sitophilus zeamais ; 73.5% in 24 h) [ 103 ]. Similar insecticidal activity of this essential oil, having 2-undecanone as the major component, was observed against two flour beetles, Tribolium castaneum and T. confusum in the contact toxicity assay, and the LD 50 value was determined as being 0.09–0.13 μL/cm 2 [ 32 ].…”

Ruta Essential Oils: Composition and Bioactivities

et al. 2021

View full text Add to dashboard Cite

Ruta L. is a typical genus of the citrus family, Rutaceae Juss. and comprises ca. 40 different species, mainly distributed in the Mediterranean region. Ruta species have long been used in traditional medicines as an abortifacient and emmenagogue and for the treatment of lung diseases and microbial infections. The genus Ruta is rich in essential oils, which predominantly contain aliphatic ketones, e.g., 2-undecanone and 2-nonanone, but lack any significant amounts of terpenes. Three Ruta species, Ruta chalepensis L., Ruta graveolens L., and Ruta montana L., have been extensively studied for the composition of their essential oils and several bioactivities, revealing their potential medicinal and agrochemical applications. This review provides a systematic evaluation and critical appraisal of publications available in the literature on the composition and bioactivities of the essential oils obtained from Ruta species and includes a brief outlook of the potential applications of nanotechnology and chitosan-based products of Ruta essential oils.

Larvicidal and repellent activity of essential oils from wild and cultivated Ruta chalepensis L. (Rutaceae) against Aedes albopictus Skuse (Diptera: Culicidae), an arbovirus vector

Rutaceae are widely recognized for their toxic and repellent activity exerted against mosquitoes. In our research, the essential oils extracted from fresh leaves of wild and cultivated plants of Ruta chalepensis L. (Rutaceae) were evaluated for larvicidal and repellent activity against the Asian tiger mosquito, Aedes albopictus Skuse (Diptera: Culicidae), currently the most invasive mosquito worldwide. In this research, gas chromatography and gas chromatography-mass spectrometry analyses of the essential oils from wild and cultivated plants showed only quantitative differences, in particular relatively to the amounts of ketone derivatives, while the qualitative profile evidenced a similar chemical composition. Both essential oils from wild and cultivated R. chalepensis plants were able to exert a very good toxic activity against A. albopictus larvae (wild plants, LC(50) = 35.66 ppm; cultivated plants, LC(50) = 33.18 ppm), and mortality was dosage dependent. These data are the first evidence of the toxicity of R. chalepensis against mosquitoes. Furthermore, the R. chalepensis essential oil from wild plants was an effective repellent against A. albopictus, also at lower dosages: RD(50) was 0.000215 μL/cm(2) of skin, while RD(90) was 0.007613 μL/cm(2). Our results clearly evidenced that the larvicidal and repellent activity of R. chalepensis essential oil could be used for the development of new and safer products against the Asian tiger mosquito.
