Jawalkar, N.B., S.P. Zambare and M.I. Al Ghannoum. 2021. The Potency of Six Medicinal Plant Extracts Against the Stored Grain Insect Pest Sitophilus granarius L. Arab Journal of Plant Protection, 39(4): 323-328. https://doi.org/10.22268/AJPP-039.4.323328 This study was conducted on six medicinal plants viz., Vitex negundo (leaves), Xanthium strumarium, Caesalpinia bonduc, Mucuna pruriens, Moringa oleifera (seed kernels), Tagetes erecta (petals) for their bio-insecticidal activity. The powders of various parts of plants were extracted using the MARS6 microwave acid digestion system. Three different concentrations (20, 30, and 40%) of plant extracts were tested against granary weevil, Sitophilus granarius L. (Coleoptera: Curculionidae) for their bio-insecticidal activities under laboratory conditions. The results of statistical analysis showed a good performance of all plant extracts, especially at the high concentrations of the extracts, where they showed different levels of insect mortality and their developmental rate was also reduced leading to significant reduction in insect numbers. The mortality rate ranged was 0-100% with S. granarius adults (p < 0.01). There was significant correlation (R=1) between mortality rate and the concentration of plant extracts. However, the extract of Mucuna pruriens with solvents (Acetone + Petroleum Ether) showed the highest mortality rate of 100% at the three concentrations used (p < 0.01), whereas, the lowest average mortality of 43.3% (p < 0.01) was observed with Xanthium strumarium and Vitex negundo extracts with solvents (Methanol + n-Hexane) compared with 0% mortality in the control. All plant extracts have revealed insecticidal as well as propitious protective effect on grains, and it can be selected as effective control treatment after proper dose formulation to prevent weevil infestation in stored grains.

Hassan, H. M., Jiang, Z.-H., Asmussen, C., McDonald, E. and Qin, W. 2014. Antibacterial activity of northern Ontario medicinal plant extracts. Can. J. Plant Sci. 94: 417–424. In the present study, the antibacterial activity (in vitro) of the leaf and/or flower crude extracts of Anaphalis margaritacea (L.) Benth & Hook.f., Grindelia squarrosa (Pursh) Dunal, Apocynum androsaemifolium L., Arctostaphylos uva-ursi (L.) Spreng, Cornus canadensis L. and Xanthium strumarium L. medicinal plants was analyzed through the hole-plate diffusion, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) assays against Escherichia coli, Aeromonas caviae, Paenibacillus alvei, Micrococcus luteus, Mycobacterium avium subsp. avium and Bacillus cereus bacteria. In addition, the time-kill dynamic processes of these extracts against A. caviae, B. cereus, P. alvei, and M. luteus bacteria were also tested. The leaf and flower extracts of Anap. margaritacea and G. squarrosa possess significant antibacterial activity against all the bacteria tested, with inhibition of A. caviae, P. alvei and M. luteus within 1–12 h of incubation at MBC. Particularly, at higher concentrations of the Anap. margaritacea flower crude extract (2–3×MBC), inhibition of A. caviae, B. cereus, P. alvei, and M. luteus bacteria is achieved between 0.5 and 4 h of incubation. In addition, these extracts exhibit high inhibition diameters (majority > 18 mm) and low MIC and/or MBCs (majority=1.25 mg mL−1). In contrast, the leaf extracts of Arct. uva-ursi, X. strumarium, Apoc. androsaemifolium and C. canadensis plants demonstrate moderate to low activity. These results indicate that extracts from Anap. margaritacea and G. squarrosa could be a source of novel antimicrobial scaffolds, compounds or pharmacophores with implications in the pharmaceutical industry and medicine.

Pulse Beetle

Background: The bruchid Callosobruchus chinensis (L.) is one of the major store grain pest of pulses capable of attacking wide range of legumes viz., green gram, black gram, chick pea and pigeon pea and causes 50 per cent damage during storage within 3 to 4 months. The infestation starts in the field, but heavy damage is done in storage. Hence, the current study was aimed to evaluate the insecticidal, oviposition deterrent and antifeedant activity of certain plant extracts against pulse beetle, C. chinensis under storage condition.Methods: The aquous extracts (10%) of Vitex negundo, Pongamia glabra, Cassia angustifolia and Calotropis gigantea were evaluated against the pulse beetle, Callosobruchus chinensis Linn. were carried out at the Department of Agricultural Entomology, Imayam Institute of Agriculture and Technology, Thuraiyur during 2019-20. The commercial product Azadirachtin was kept as a check and the mortality rate was assessed every 24 Hours after treatment (HAT) for three days.Result: The mortality rate after 72HAT was 85.8-87.5% with V. negundo, followed by C. angustifolia (73.33-80.00%) and P. glabra (70.0-75.0%). Azadirachtin gave 100% mortality of the beetle. The oviposition deterrence percentage for pulse beetle, C. chinensis was found to be highest in Calotropis gigantea (37.66-68.16%) followed by Pongamia glabra (30.91-41.50) and Vitex negundo (7.58-46.75) per cent, respectively. The antifeedant activity for pulse beetle was found to be very high when treated with Azadirachtin where there was no food consumption. This was followed by V. negundo (0.1g) and C. angustifolia (0.2g).

The Mean

Different insect pests attack stored grain products during storage. T. castaneum are the most threatening pests of stored grains. Feeding of adults and larvae is stored grains. The extracts of Datura stramonium and Zingiber officinale prepared with acetone and Deltamethrin was applied. Five concentrations 0.01%, 0.02%, 0.03%, 0.04%, 0.05% were prepared with one controlled concentration of both the plants and the Deltamethrin. Treatments were applied on the filter paper check their possible lethal effects against T. castaneum. The data concerning mortality was recorded after time interval 24, 48 and 72 hours and analyzed statistically using ANOVA (analysis of variance) and comparison of means of treatment means was analyzed with the help of Tuckey’s honestly significant difference (THSD) test. The mean mortality of Tribolium castaneum were 90% after 72 hours by exposure of Deltamethrin. The mean values of % mortality caused by effect of Datura stramonium against T. castaneum was 52%. The mean values of % mortality caused by plant extract Zingiber officinale against T. castaneum was 41% after 72 hours. Results revealed that Deltamethrin is more effective than plant extracts. Datura stramonium is more effective than Zingiber officinale.
