“…The control papers were impregnated with aqueous plant extract, TiO 2 solution (positive control), and synthesized TiO 2 NPs. The dose-response data were subjected to probit analysis to determine the LC 50 value for 24 h exposure under constant climatic conditions (25°C; 12 h/12 h, L/D) as per the method of Nyamador et al (2010).…”

Titanium dioxide nanoparticles (TiO2 NPs) are considered to be among the best photocatalytic materials due to their long-term thermodynamic stability, strong oxidizing power, and relative non-toxicity. Nano-preparations with TiO2 NPs are currently under investigation as novel treatments for acne vulgaris, recurrent condyloma acuminata, atopic dermatitis, hyperpigmented skin lesions, and other non-dermatologic diseases. The present study was to investigate the acaricidal and larvicidal activity of synthesized TiO2 NPs utilizing leaf aqueous extract of Mangifera indica L. (Anacardiaceae) against hematophagous parasites. The anti-parasitic activity of TiO2 NPs against the larvae of Rhipicephalus (Boophilus) microplus, Hyalomma anatolicum anatolicum and Haemaphysalis bispinosa (Acari: Ixodidae), fourth instar larvae of Anopheles subpictus, and Culex quinquefasciatus (Diptera: Culicidae) were assessed. The green synthesized TiO2 NPs were analyzed by UV-Vis, FTIR, X-ray diffraction (XRD), AFM, SEM, and TEM. The XRD analysis of synthesized TiO2 NPs revealed the dominant peak at 2θ value of 27.81 which matched the 110 crystallographic plane of the rutile structure indicating the crystal structure. The FTIR spectra exhibited a prominent peak at 3,448 cm(-1) and showed OH stretching due to the alcoholic group, and the OH group may act as a capping agent. The SEM images of TiO2 NPs displayed spherical, oval in shape, individual, and some in aggregates. Characterization of the synthesized TiO2 NPs using AFM offered three-dimensional visualization and uneven surface morphology. The TEM micrograph showed agglomerates, round and slight elongation with an average size of 30 ± 5 nm. The maximum efficacy was observed in synthesized TiO2 NPs against the larvae of R. microplus, Hyalomma anatolicum anatolicum, Haemaphysalis bispinosa, A. subpictus, and Culex quinquefasciatus with LC50 value of 28.56, 33.17, 23.81, 5.84, and 4.34 mg/L, respectively. In the present study, a novel, simple, and eco-friendly approach has been suggested to control blood-feeding parasites.

The present investigation was aimed to analyse the chemical composition of essential oil isolated from Heracleum persicum Desf. ex Fischer and assess its lethal and sub-lethal effects against Tribolium castaneum (Herbst). Essential oil from hydro-distilled seeds of H. persicum was analyzed by gas chromatography-mass spectrometry (GC-MS), and hexyl butyrate (50.58%), octyl acetate (9.80%) and hexyl hexanoate (8.75%) were found as principal constituents. Repellent activity, contact and fumigant toxicity and antifeedant effects of this oil were assessed against the adults of T. castaneum. The essential oil strongly repelled T. castaneum adults even at the lowest concentration (0.035 μL cm -2 ). Complete repellency (100%) occurred when the highest concentration (0.212 μL cm -2 ) was applied for 8 h. T. castaneum was very susceptible to H. persicum oil at both contact and fumigant bioassays. In the fumigant toxicity, essential oil killed the larvae, pupae and adults and significantly decreased larvae emerged from treated eggs. LC 10 to LC 40 values of fumigation adult's bioassay as sub-lethal concentrations were used to evaluate the antifeedant effects. H. persicum essential oil has significant antifeedant effects on T. castaneum adults and decrease of feeding happened when oil concentrations increased. The results of the present study indicate that essential oil of H. persicum, with wide bio-effects on T. castaneum, is a source of biologically active agents which may potentially prove to be efficient insecticides.Additional key words: essential oils; Heracleum persicum; toxicity; repellent; antifeedant.* Corresponding author: asgar.ebadollahi@gmail.com Received: 12-07-14.

“…These botanicals were reported as effective grain protectants when tested alone or in combination with natural products such as diatomaceous earth (Athanassiou et al 2004(Athanassiou et al , 2005Kavallieratos et al 2007). Such compounds may act as contact insecticides (Ho et al 1995;Nenaah 2010;Saroukolai et al 2010), fumigants (Rice and Coats 1994;Shaaya et al 1997;Liu and Ho 1999;Kéita et al 2001;Ilboudo et al 2010), repellents (Saim and Meloan 1986;Papachristos and Stamopoulos 2002;Wang et al 2006), and antifeedants Liu and Ho 1999) and may affect certain parameters disrupting the growth rate, life span, and reproductive potential of insect pests (Stamopoulos 1991;Regnault-Roger and Hamraoi 1994;Nyamador et al 2010). Traditionally, plant materials have played an important role in the protection of grains against insect infestation in Africa since ancient times.…”

Powders and essential oils were prepared from the aerial parts of Cinnamomum camphora, Ocimum basilicum, Chenopodium ambrosioides, and seeds of Pimpinella anisum. Their adulticidal activities and effects on the F 1 progeny of Trogoderma granarium (Everts) and Tribolium castaneum (Herbst) were evaluated. The chemical composition of the plant oils were identified by gas chromatography (GC) and GC/mass spectrometry (MS). All of the tested botanicals showed insecticidal activities against the test insects in a dose-dependent manner with T. granarium was more susceptible to the tested plant products than T. castaneum. At a concentration of 5 g kg -1 , many of the plant powders caused 100% mortality of both insects after 14 days of exposure. The powders of C. camphora, O. basilicum, and C. ambrosioides were effective against T. granarium, while that of C. ambrosioides caused 100% adult mortality of T. castaneum under the same assays conditions. A dose of 1.50 ml cm -2 of the oils of C. camphora and O. basilicum completely controlled T. granarium, while 100% mortality of T. castaneum adults was recorded with P. anisum oil. A significant and/or complete reduction (100% inhibition) of the F 1 progeny of both insects was obtained as a result of parental exposure to the tested botanicals, especially at the highest doses applied. Botanicals under investigation showed a considerable grain protecting activity against the tested insect species and could be included in integrated pest management (IPM) strategies.
