“…and the values in % if given. * 3 The snails of the measurements of Fischbach et al [21] are separated in three different groups based on their shell diameter. Group 1 with 0.65-0.85 cm diameter, group 2 with 0.9-1.0 cm and group 3 with 1.0-1.25 cm.…”

“…Its life cycle can be annual or biennial, depending on its habitat [2]. In relation to the entire distribution range of the species, the snails studied here derived from a warmer (Mediterranean) habitat, and their life cycle is therefore most probably annual [3]. They hatch in winter and the young snails grow in spring until they reach their adult size by summer [4].…”

Metabolism, mainly driven by oxygen consumption, plays a key role in life, as it is one of the main ways to respond to extreme temperatures through internal processes. Theba pisana, a widespread Mediterranean land snail, is exposed to a wide range of ambient temperature. In this species the oxygen consumption was tested as a response variable by multiple regression modelling on the “explanatory” variables shell-free mass, temperature, and relative humidity. Our results show that the oxygen consumption of T. pisana can be well described (73.1%) by these three parameters. In the temperature range from 23 °C to 35 °C the oxygen consumption decreased with increasing temperature. Relative humidity, in the range of 67% to 100%, had the opposite effect: if it increases, oxygen consumption will increase as well. Metabolism is proportional to an individual’s mass to the power of the allometric scaling exponent α, which is between 0.62 and 0.77 in the mentioned temperature range. CT scans of shells and gravimetry revealed the shell-free mass to be calculated by multiplying the shell diameter to the third power by 0.2105. Data were compared to metabolic scaling exponents for other snails reported in the literature.

“…This species is widely distributed in various regions at Sharkia Governorate, Egypt. T. pisana is particularly dangerous due to its small size, capacity to survive long and explosive reproductive rates, which can result in up to 3,000 snails on a tree in less than five years (Cowie 2009, Deisler et al 2015. During one breeding season, T. pisana produced up to 4566 eggs / couple (Cowie, 1984;Baker, 1991).…”

Theba pisana is considered one of the most prevalent and dangerous land snails in the Mediterranean region especially in Egypt. Owing to their small sizes, climbing tendency, capability of producing hazardous effects on plants and, high reproductive rates, all these make difficulties of their effective control. The goal of the current study was to control this harmful snail by applying The Ovunhipita contraceptive pills. Three different concentrations of the drug (0.75, 1.5, and 3 µg/g) were tested on the reproductive biology, antioxidant enzymes and the histological structures of both hermaphroditic and digestive glands after 6 weeks of treatments using baits technique.Results indicated that egg masses laid / snail were decreased significantly (0.25, 0.15, and 0.15 egg mass/snail) after treatment with 0.75, 1.5 and 3 µg/g, respectively compared to control (1.65 egg mass/snail). Egg numbers /mass were significantly reduced to 56, 53, and 15.9 eggs/mass respectively compared to control (91.12 eggs/ mass). In addition, the number of eggs laid by snails, the rate of hatchability was significantly decreased with increasing concentration of the drug. The tested antioxidant enzymes (CAT, SOD, and MDA) activities were increased, while GST levels were decreased significantly compared to control. Histological investigations of treated snails for 6 weeks showed alterations in the normal structures of both ovotestis and digestive glands. The application of a monohormonal contraceptive drug is an environmentally safe method for controlling harmful land snails in spite of using chemical pesticides.

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.
