© 2020 Parlar Scientific Publications. All rights reserved.Rcpcllency of Glycyrrhiza glabra, Zingiber officinale, Raphanus sativus var. niger and Daucus carota var. atrorubens along with pcrmcthrin dusl againsl Sitophiliis granariiis was evaluated in the laboratory at 27 ± 1 °C and 65 ± 5 % RH. The herbals were applied as dusts, methanolic, cthanolic and aqueous extracts at the rate of 5.0, 10.0 and 20.0 x 104 ppm per 40 g of wheat grains, while the pcrmcthrin dust was applied at 0.055 x 104 ppm. Percentage rcpcllency was rccordcd at 1,6, 12 and 24 hours after treatment (HAT). All the herbals were found to have a repellent effect against Sitophilus granarius at all three concentrations. The highest (90.18 ± 2.83) rcpcllcncy among the herbal dusts was exhibited by 20.0 x 104 ppm of Glycyrrhiza glabra within 24 HAT. Methanolic root extracts were found to be more effective than the other formulations, causing total rcpcllcncy against the weevils at 20.0 x 1()4 ppm of all the herbals, while the activities of the aqueous extracts were the least repellent (45.49 ± 7.49 to 64.30 ± 1.50 %) after 24 hours of exposure. The repellent activities of the herbals decreased with increasing exposure periods for dusts and aqueous extracts and increased with increasing duration for methanolic and cthanolic root extracts. The results showed that the herbals were good repellent against Sitophiliis granarius and could serve as stored wheat grain protectants against wheat granary weevil infestation.
