“…Moreover, the elevation in lactate as a result of an increase in enzyme activity clearly shows metabolic disturbance. This confirms a previous report that demonstrated inhibition of LDH in fourth‐instar larvae of Spodoptera littoralis 48 h after treatment with a lethal concentration of EMB 68 …”

BACKGROUND The white garden snail, Theba pisana, is distributed worldwide and is a serious molluscan pest of different crops. Emamectin benzoate (EMB) ‘an avermectin derivative’ is a novel biorational agent and highly effective pesticide. This study focused on the lethal and in vivo sublethal toxic effect of EMB on the energy reserves (glycogen, lipids and proteins), total energy reserves and activities of glutathione S‐transferase (GST), γ‐glutamyl transferase (γ‐GT), lactate dehydrogenase (LDH), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in the hepatopancreas of T. pisana for up to 7 days of exposure. RESULTS The median lethal dose (LD50) at 48 h of EMB treatment was 5.34 μg g−1 body weight (b.w.). Sublethal doses of 1.07 and 3.20 μg g−1 b.w. (i.e., 20% and 60% of the LD50) led to significant dose‐ and time‐dependent decreases in glycogen and lipids; these doses increased the total protein level. Overall, the tested sublethal doses significantly decreased the total energy reserves. Moreover, GST and γ‐GT activities were elevated, whereas the activities of AST and ALT were inhibited in the exposed snails. A decrease in LDH activity after 1 and 3 days of exposure and an increase after 7 days of exposure were seen in snails treated with EMB. CONCLUSION EMB exerted lethal toxicity on T. pisana and consequently caused changes in energy reserve levels and enzyme activities in the animal. © 2022 Society of Chemical Industry.

High population densities of Monacha cartusiana were observed to cause perdition of various economic crops at Sharkia Governorate. The present study was carried out control this harmful pest using ethanolic Ginger extract as a natural and environmentally safe molluscicide.Toxicological tests revealed that low concentration (20%) of ethanolic Ginger extract caused 10 % mortalityof cloversnails after one day of exposure and 66.7% mortalityafter28 days. The highest mortality percentage (90 %) was recorded after 28 days of treatment with40% Ginger extract. Biochemical investigations showed thatLC 25 (7.04%) Ginger extract elevated ALT, AST, α & β esterases andphenoloxidase levels of treated snails compared to control.Histological inspections of the digestive gland and ovotestis of snails exposed to LC 25 Ginger extract revealed that the digestive tubules showedvarious tubularanomalies, inflammatory hemocytes infiltration, excessive luminal secretionsand appearanceof necrotic areas. Acini of ovotestis weredeformedand comprised misshapen eggs and distorted sperms.TEM investigations showed cellular malformations in the digestive gland of treated snails including; severely disrupted microvilli, ruptured cell membranes, fractured RER and mitochondrial pyknosis.
