Effects of Citrullus colocynthis agglutinin on intermediary metabolism of Ectomyelois ceratoniae Zeller (Lepidoptera: Pyralidae)

Effects of Teucrium polium L. (Lamiaceae) essential oil and α-pinene on the detoxifying- and intermediary engaged enzymes of Ephestia kuehniella Zeller, 1879 (Lep.: Pyralidae)

“…Citrullus colocynthis (L.) Schrad agglutinin caused significantly lower activity of aldolase in the fourth instar larvae of Ectomyelois ceratoniae (Zeller, 1839) (Lep. : Pyralidae) after 48 h of post-treatment (Ramzi et al, 2014). In addition, Selin-Rani et al (2016) demonstrated that methanol extract of Alangium salvifolium (L.f.) Wangerin caused lower activity of LDH in the larvae of Spodoptera litura (F., 1775) (Lep.…”

“…Our results showed that activity of γ-GT increased in the treated larvae by Tp EO and α-pinene. In transamination cycle of insects, γ-glutamyl transferase (γ-GT) plays an important role in synthesizing glutathione and detoxifying xenobiotic compounds (Ramzi et al, 2014). Increased activity of γ-GT following treatments by EOs can be due to removal of these compounds in the hemolymph of larvae as other reports (Ramzi et al, 2014;Shahriari et al, 2017b).…”

“…: Noctuidae) have shown similar changes in phosphatases activities after treatments by botanical pesticides (Senthil- Nathan, 2006;Zibaee & Bandani, 2010;Hasheminia et al, 2011;Mojarab-Mahboubkar & Sendi, 2016). The higher activity of phosphatase suggests potential involvement in the detoxification and metabolize of toxic compounds (Hasheminia et al, 2011;Shahriari et al, 2017b) so that any decrease in phosphatase activities of treated larvae with botanical insecticides may refer to changes in physiological balance in the midgut of insects causing lower dephosphorylation of phosphate groups for energy production (Senthil- Nathan, 2006;Ramzi et al, 2014;.…”

Changes in immune responses of Helicoverpa armigera Hübner followed by feeding on Knotgrass, Polygonum persicaria agglutinin

“…Decrease in plasmatocytes number was reported by Sharma et al () by 24–72 hr after treatment with A. calamus essential oils in Spodoptera littoralis . Some studies have reported that plant lectins cause cytotoxicity through apoptosis process by activation of caspase enzymes (Rahimi et al, ; Ramzi et al, ; Shahidi‐Noghabi et al, ; Sprawka et al, ). Apoptosis process and autophagy in insect cell lines such as hemocytes following azadirachtin have been reported by Shu et al ().…”

“…Sadeghi, Smagghe, Jurado‐Jacome, Peumans, and van Damme () showed that Transgenic tobacco plants expressing leek agglutinin decreased larval and pupal weight, retarded immature development, and increased mortality rate in Spodoptera littoralis Boisduval (Lepidoptera: Noctuidae). Ramzi, Sahragard, and Zibaee () reported that Citrullus colocynthis agglutinin significantly reduced ecological performance of Ectomyelois ceratoniae Zeller (Lepidoptera: Pyralidae) through discrepancies in intermediary metabolism of larvae. Rahimi, Hajizadeh, Zibaee, and Jalali Sendi (a, b) demonstrated that Polygonum persicaria lectin not only reduced nutritional performance and life table parameters but also induced antioxidative stress in Helicoverpa armigera Hübner (Lepidoptera: Noctuidae).…”
