“…This underscores the importance of H. suaveolens as a mosquitocidal and an insecticidal plant in the communities visited in Southwestern Nigeria. This is in consonant with reported repellent and insecticidal activities of H. suaveolens leaf essential oil against four stored-grain coleopteran pests [68]. Also, Chromolaena odorata, Nicotiana tabacum, Ocimum gratissimum and Xylopia aethiopica, each had the UMi of 0.167.…”

Ipomoea reniformis Chaos is claimed in Indian traditional medical practice to be useful in the treatment of epilepsy and neurological disorders. In the present study, pretreatment effect of methanolic extract of Ipomoea reniformis on epilepsy and psychosis was evaluated in rodents using standard procedures. Besides evaluating epileptic and behavioral parameters, neurotransmitters such as Gamma-Amino Butyric Acid (GABA) in epilepsy and in psychosis dopamine, noradrenaline and serotonin contents in the rodent brain were estimated. The extract pretreatment reduced maximal electro shock; Isoniazid (INH) and Pentylenetetrazole (PTZ) induced seizures and also significantly inhibited the attenuation of brain GABA levels by INH and PTZ in mice. These results suggested that the observed beneficial effect in epilepsy may be by enhancing the GABAergic system. The test drug also inhibited the apomorphine induced climbing and stereotyped behavior and showed significantly reduced levels of brain dopamine, noradrenaline and serotonin which may be due to blocking of central dopaminergic, noradrenergic and serotonergic pathways or by enhancing the GABAergic system. The results obtained in present study suggest that the title plant possesses antiepileptic and antipsychotic activities in rodents.

“…In this study, Lavender EO had the highest toxicity activity for rice weevils with 100% mortality effect at 6 mg/cm 2 at 12 and 48 h exposure time, in addition to the basil EO also had the highest mortality percentage 100% at 6 mg/cm 2 at 12 h, this result was in agreed with [ 53 ], who reported the toxicity effect of basil, fennel, and geranium EOs against S. oryzae and C. maculatus through assessment of repellence and progeny production. Quick repellence activity in this study was highest for basil EO that recorded 61.2% for 0.75 mg/cm 2 after 1 h against adult S. oryzae where repellence reached 82% after 5 h, theses result like results of [ 54 ], that reported repellence against S. oryzae after 1 h was 91.1%.…”

The risk of using synthetic insecticides to the environment, human health, and the emergence of new genera of pests resistant to that kind of drugs, have led to attention in natural compounds. The present study aimed at evaluating the insecticidal activity of 0.25–6 mg/cm2 of basil (Ocimum basilicum), black seeds (Nigella sativa), and lavender (Lavandula angustifolia) essential oils (EOs) against one of the major stored product pests, Sitophilus oryzae (L.). This was done by assessing mortality and repellent percentage assay in the adult stage, as well as analysing up and down-regulated genes associated with toxicity effect of selected EOs. The three studied EOs showed a toxic effect on S. oryzae; where O. basilicum and L. angustifolia EOs explicated 100% mortality at 6mg/cm2 after 48 and 24 h, respectively. The highest repellence activity was recorded for O. basilicum EO at 0.75 mg/cm2 with value 82.3% after exposure time 5 h. In the highest dose (6 mg/cm2), the maximum up-regulated expression level of detoxification DEGs genes (CL1294 and CL 8) and cytochrome p45o gene (CYP4Q4) in Lavandula angustifolia EOs exhibited 8.32, 6.08, and 3.75 fold changes, respectively, as compared with 4.76 fold at 10 ppm malathion and 1.02 fold change in acetone control.

ObjectiveThe aim of the study was to check whether Carum carvi L. essential oil and L-carvone act on Sitophilus oryzae L. as repellents and/or insecticides, in what concentrations and after what time. ResultsCaraway essential oil and L-carvone the highest repellency showed not in the highest concentrations used in the tests (1%), but in lower concentrations, respectively 0.5% and 0.1%. Caraway essential oil in all used concentrations showed repellent effects on S. oryzae. The highest repellency (60-98%) caused caraway essential oil in concentration 0.5% after 1, 2, 3, 4 and 5 h of the research. The highest repellence of L-carvone (16-100%) resulted in concentration 0.1%. The highest mortality of S. oryzae caused 0.5% caraway essential oil.
