Plant‐Derived Substances Used Against Beetles–Pests of Stored Crops and Food–and Their Mode of Action: A Review

“…Wang et al. () presented a thesis that the essential oils of Citrus limonum and Allium sativum could serve as effective control agents of the darkling beetle, A. diaperinus . It was observed that the strongest fumigant activity appeared between 48 and 96 hr post‐treatment, when 6th instars larvae were treated.…”

Diuretic and antioxidant activities of the aqueous extract of leaves of Cassia occidentalis (Linn.) in rats

“…Extracts of this plant were reported antifungal, antiviral [9,10], antibacterial, anthelmintic [11,12], antispasmodic, analgesic, antipyretic, anti-inflammatory [13,14], and hepatoprotective properties in humans and experimental models [15,16]. Verma and colleagues (2010) showed the effect of ethanolic extract of C. occidentalis for the management of alloxan-induced diabetic rats [17,18], and Sreejith and colleagues reported anti-allergic, anti-inflammatory and anti-lipid peroxiding effects [19].…”

IMPACT OF EXTRACTS OF Azadirachta indica AND Datura inoxia ON THE ESTERASES AND PHOSPHATASES OF THREE STORED GRAINS INSECT PESTS OF ECONOMIC IMPORTANCE

“…Same findings by other biopesticides were also reported in numerous insect pests (Wanchun et al, 1999;Breuer et al, 2003;Nathan et al, 2008).Based on our results all the plants inhibit the AChE activity but initially at lower dilution levels inhibition was also lower and inhibition of AChE increases with increase in dilution rate. These studies are supported by Wang et al (2014), they checked four essential oils extracted from Citrus limonum, Litsea cubeba, Cinnamomum cassia and Allium sativum against Alphitobius diaperinus (Coleoptera: Tenebrionidae) pest of stored poultry feed. They reported that all essential oils reported significant inhibition of AChE activity, but essential oil of A. sativum forced maximum inhibition (>80%) of AChE activity, they also verified that with passage of time inhibition of AChE activity also increased.…”

“…Same procedure was followed for alkaline phosphatases (ALP) except 450µl Tris HCl (50mM, pH-8) was used in place of sodium acetate buffer. Enzyme inhibitions (%) of test enzymes were computed by the formula given by Wang et al (2014). Enzyme Inhibition ODb = Optical density of blank (control treatment), ODo = Optical density of treatments Statistical analyses: In all trials, separate ANOVA was performed for each insect against plant extract of Datura inoxia and Azadirachta indica.…”
