Ultimate Objective

Chemical pesticides used against insect pests of stored food have adverse effects on both health and the environment. So, the present study aims to evaluate the insect repulsive and insecticidal power of Ruta chalepensis L. essential oil (EO) from the region of Oulmes (Central plateau of Morocco); the ultimate objective is to develop a biological and ecological control strategy against pests. Thus, the EO obtained by hydrodistillation from the aerial parts of Ruta chalepensis L. was identified by GC-MS; its repellent and fumigant toxicity effects on adults of Tribolium castaneum Herbst were, respectively, investigated by the preferential area method on a filter paper and the inhalation test. The insecticide power was estimated by determining the percentage of mortality as a function of the duration of exposure and concentration of the EO. The essential oil obtained is characterized by the dominance of 2-undecanone (64.35%), piperonyl piperazine (11.9%), 2-decanaone (5.12%), 2-dodecanone (4.52%), decipidone (3.9%,) and 2-tridecanone (2.36%). This EO is endowed with a very repulsive power belonging to class V, which is strongly due to its majority compound 2-undecanone. The dose 0.038 μl/ml gave a repellent power of 100% after 15 min. The tests also revealed a considerable insecticidal effect, which reached 100% after 48 hours at a dose of 0.62 μl/ml. The calculation of the lethal dose causing 50% mortality (LD50) and the lethal times after which there is 50% mortality (LT50) allowed deducing that the insecticidal effect of Ruta chalepensis L. is time- and dose-dependent. Hence, the effectiveness of Ruta chalepensis L. EO attests that it can constitute a healthy alternative to fight against Tribolium castaneum Herbst.

The insecticidal potential of the Saharan plant Cotula cinerea, was evaluated on two insect species namely Aphis fabae and Tribolium castaneum by topical application (contact toxicity) and repellency test. A crude ethanolic extract of aerial part of the plant was prepared and tested in the laboratory on adults of both species. For contact toxicity, five doses were tested on each of the two species 1.56, 3.12, 6.25, 12.5 and 25 mg/ml for A. fabae and 25, 50, 250, 350 and 500 µg/insect for T. castaneum. The repellency of the extract was studied at the dose 500 μg/insect for T. castaneum and 25 µg/ml for A. fabae. Results showed that the repellency of the extract increased with exposure time and the highest rates were observed after 4 h of exposure (72.33 ± 22% for T. castaneum and 87 ± 3.6% for A. fabae). For insecticidal activity, at the highest doses (25 mg/ml and 500 µg/ml), 100% mortality is obtained 72 h after treatment for A. fabae and after 48 h for T. castaneum. The extract of this plant was found to be more toxic against T. castaneum adults. LD50 calculated 24 h after treatment for the two species is estimated at 1.7 mg/ml for A. fabae and at 30.3 µg/insect for T. castaneum. The extract of this plant inhibited the activity of acetylcholinesterase (AChE) in both insect species. This result suggests that this plant has a neurotoxic effect on A. fabae and T. castaneum. The results of phytochemical study showed that the plant is mainly rich in flavonoids, gallic tannins, alkaloids, saponosides and glucosides. The insecticidal effect obtained in this study could be due to the synergetic action of all constituents of the extract. Results suggest the possibility of using the extracts of this plant in integrated pest management to replace the chemical insecticides.

Essential oils extracted from leaves and fruits of Schinus areira (Anacardiaceae) were tested for their repellent, toxic and feeding deterrent properties against Tribolium castaneum (Coleoptera: Tenebrionidae) larvae and adults. A topical application assay was employed for the contact toxicity study and filter paper impregnation for the fumigant assay. A treated diet was also used to evaluate the repellent activity and a flour disk bioassay for the feeding deterrent action and nutritional index alteration. The essential oil of the leaves contained mainly monoterpenoids, with α-phellandrene, 3-carene and camphene predominant, whereas that from the fruits contained mainly α-phellandrene, 3-carene and β-myrcene. The leaf essential oil showed repellent effects, whereas that from the fruit was an attractant. Both oils produced mortality against larvae in topical and fumigant bioassays, but fumigant toxicity was not found against adults. Moreover, both essential oils produced some alterations in nutritional index. These results show that the essential oils from S. areira could be applicable to the management of populations of Tribolium castaneum.

Essential oils of plants with insecticidal properties have been considered as replacements for synthetic chemical pesticides to combat and control insect pests. The chemical composition of the essential oil from dried seeds of Zanthoxylum limonella Alston was determined by the Gas Chromatograph-Mass Spectrometry technique. Insecticidal activity was investigated on Tribolium castaneum Herbst using impregnated filter paper with six concentrations of essential oil at 0, 1, 2, 3, 4, and 5% for adults and larvae mortality tests, and 0, 2, 4, 6, 8 and 10% for egg mortality. All experiments were performed under completely randomized design (CRD) with four replications at 30±5°C and 70±5% relative humidity in 16:8 hours light/dark cycle. A total of 83 components were identified. The principal compounds in the essential oil of Z. limonella were beta-pinene (19.65%), 9-octadecanone (18.80%), D-limonene (9.76%), alpha-fenchene (8.48%), p-mentha-1,5,8-triene (7.16%), 1,8-cineole (6.88%), gamma-terpinene (5.46%), terpinen-4-ol (3.81%), linalool (2.73%), alpha-thujene (1.34%), decanal (1.32%), alpha-phellandrene (1.20%) and linalyl propionate (1.13%). Insecticidal activity presented that 5% of essential oil had the highest effect against T. castaneum at 120 h for adults and 48 h for larvae, while 10% of essential oil at 14 days obtained 100% mortality against eggs of T. castaneum. Results indicated that the essential oil of Z. limonella from dried seeds showed potential for use in the control of T. castaneum

Ovicidal Effect

Context: The essential oils are being tried as potential candidates for pest and disease management. Several essential oils of botanical origin have been reported for their repellant, toxic and developmental inhibitory activities. The ovicidal effect of essential oil is probably the major factor in the suppression of the development of adults from treated eggs.Objectives: To investigate the ovicidal effect of vapours of five essential oils viz., cardamom (Elletaria cardamomum L.), cinnamon (Cinnamomum zeylanicum Blume), clove (Sygium aromaticum L. Merrill. et. Perry), Eucalyptus spp. and neem (Azadirectica indica A. juss) against the eggs of red flour beetle, Tribolium castaneum (Herbst).Materials and Methods: Ten eggs (24 h old) of T. castaneum were placed in each petridish with wheat flour as food medium and without flour medium and then the petridish were kept inside 650 ml jars with screwed lids. Aliquots of 0.5 ml of each dose of essential oils were applied on filter paper attached to the lower side of the lids. The exposure periods were 24, 48, 72 and 96 h, respectively. After treatment periods, petridishes were taken out of the jars and the final mortality counts were made after 11 days. Mortality data were subjected to probit analysis. Results: The oils had high-fumigant activity against eggs and toxicity progressively increased with increase in exposure time and concentration. At the highest concentration of 5.769 mg/l air and exposure period of 24 h, cinnamon oil achieved 100% mortality in flour and without flour media. The vapours of essential oils from cardamom and clove resulted in 100% mortality of the eggs. Neem oil achieved mortalities as high as 51.66 and 50% mortality at the highest concentration and exposure period in with-flour and without flour medium respectively. At a concentration of 5.769 mg/ l air cardamom oil, the LT90 values were 50.80 and 62.78 h for with-flour and without flour medium respectively.Conclusion: The essential oils of cinnamon and clove, proved to be promising as control agents against stored-product insects, especially T. castaneum.Key words: Essential oil; Fumigant toxicity; Ovicidal activity; Tribolium castaneumDOI: 10.3329/jbs.v17i0.7102J. bio-sci. 17: 57-62, 2009

The insecticidal effects of the insecticide based on the mixture of porous starch and fennel essential oil was investigated. Its insecticidal activity and its mortality on adults of Tribolium confusum were evaluated. Moreover, the production methods used in the evaluation was studied. Fennel essential oil was put into the porous starch with glycerin and ethyl acrylate. Non-woven was chosen as the substrate, and ethyl acrylate as adhesives. Then the new insecticide was made. According to the fumigant toxicity and persistent of the new insecticide, the insecticidal effect of the insecticide was analyzed. Tribolium confusum mortality was dose dependant and after 4-day exposure the insecticide was more toxic than the pure fennel essential oil. There was, however, a highly significant loss of toxicity after 24 and 48 h following treated with essential oil and insecticide, respectively. The fennel essential oil evoked moderated repellent action and high fumigant toxicity (LD50 = 0.030μL/cm3) against adults of Tribolium confusum.

<p>The lesser grain borer [<em>Rhyzopertha dominica</em> (Fabricius, 1792)] and the red flour beetle [<em>Tribolium castaneum</em> (Herbst, 1797)] are among the cosmopolitan damaging pests on several stored-products. The overuse of chemical pesticides in the control of such pests caused several side-effects including environmental contaminations, human health problems, and insect pests' resistance. In this circumstance, researchers have focused on safe and effective alternatives to chemical pesticides. In the present study, the insecticidal efficiency of essential oil extracted from the summer savory (<em>Satureja hortensis</em> L.) was assessed on the <em>R. dominica </em>and<em> T. castaneum</em> adults. The chemical profile of essential oil was evaluated through a gas chromatography-mass spectrometer, in which estragole, β-ocimene and d-limonene were the main components. The essential oil had considerable fumigant toxicity on insect pests. The mortality of insects was dependent on the essential oil concentration and exposure time. Probit analysis indicated that <em>R. dominica</em> with low LC<sub>50</sub> values (Lethal Concentration to kill 50 % of tested insects) was more susceptible than <em>T. castaneum</em>. Accordingly, <em>S. hortensis</em> essential oil with a high level of phenylpropanoid and terpenic compounds can be recommended as an efficient and natural alternative to the detrimental chemicals in the management of<em> R. dominica </em>and<em> T. castaneum</em>.</p>

The essential oil obtained from Citrus wilsonii Tanaka leaves with hydrodistillation was investigated by GC and GC-MS. The main components of the essential oil were identified to be citronellol (16.94%), nerol acetate (10.35%), ?-terpinen (9.85%), citronellal (9.36%) and ?-pinene (6.72%). Among them, the four active constituents, predicted with a bioactivity-test, were isolated and identified as citronellol, ?-terpinene, nerol (neryl) acetate and ?-pinene. It was found that the essential oil of C. wilsonii leaves and isolated compounds possessed fumigant and contact toxicity against Tribolium castaneum adults. The essential oil and ?-terpinen showed strong fumigant toxicity against T. castaneum (LC50 = 8.18 and 4.09 mg L-1). Repellency of the crude oil and active compounds was also determined. Citronellol, neryl acetate and ?-pinene were strongly repellent (100%, 86% and 92%, respectively, at 78.63 nL cm-2, after 2 h treatment) against T. castaneum. The essential oil and citronellol exhibited the same level of repellency compared with the positive control, DEET. The results indicate that the essential oil of C. wilsonii leaves and its active compounds had the potential to be developed as natural fumigants, insecticides and repellents for control of T. castaneum.

AbstractAttempts have been made in recent years to reduce the use of synthetic pesticides and seek alternative and innovative methods for pest control. We conducted a study on the chemical composition ofEucalyptus occidentalisessential oil and investigated the fumigant, contact and repellent effects againstTribolium castaneum(Herbst) (Col: Tenebrionidae) andRhyzopertha dominica(F.) (Col: Bostrichidae). The major components were τ-cadinol (17.20), 1,8-cineol (15.5%), α-cadinol (14%) and α-pinene (9.21%). The contact toxicity experiment showed that the oil was more toxic toR. dominica(LD50value 0.82 μL/cm) than toT. castaneum(LD50value 0.99 μL/cm) and showed the same fumigant toxicity for both insects according to the 95% confidence limit of LC50. The repellency againstT. castaneumwas more than forR. dominicaand increased from 14 to 75% forR. dominicaand 22 to 78% forT. castaneumafter 2 h. These results suggest thatE. occidentalisessential oil is a potential candidate for use as a natural repellent and insecticide for stored-product insect pests.
