چکیده
The effect of clodinafop –propargyl against the mucus land snail, Helix aspersa, was studied under laboratory and field conditions during autumn 2020 season. Snails were exposed to serial concentrations clodinafop-propargyl for successive seven days using contact bait techniques. Median Lethal concentration (LC50) determined LC25 test compound examined on total protein alkaline phosphatase after treatment. In field, used poison evaluated 21 H. aspersa mango nursery trees at a reclaimed in Abu- Rwash, Giza Governorate, Egypt. (25.200 ppm) compared with methomyl (4.000 recommended by Ministry Agriculture Land Reclamation trials. effects 1, 3,7, 15, treatment both compounds. Based data LC50 6.750 ppm 8.250 method Moreover, caused reduction control. 90.7% snail population 75.0% Therefore, it be concluded that can as control programs combat snails

Evidence for genetic control of adult weight plasticity in the snail Helix aspersa.
Phenotypic plasticity and canalization are important topics in quantitative genetics and evolution. Both concepts are related to environmental sensitivity. The latter can be modeled using a model with genetically structured environmental variance. This work reports the results of a genetic analysis of adult weight in the snail Helix aspersa. Several models of heterogeneous variance are fitted u...
متن کاملHypometabolism, antioxidant defenses and free radical metabolism in the pulmonate land snail Helix aspersa.
The aim of this work was to evaluate the effect of a cycle of estivation and awakening on free radical metabolism in selected organs of the land snail Helix aspersa. Estivation for 20 days induced a 4.9- and 1.8-fold increase in selenium-dependent glutathione peroxidase activity (Se-GPX) and in total glutathione levels (GSH-eq), respectively, in hepatopancreas when compared to activity in activ...
متن کاملAssociative learning phenomena in the snail (Helix aspersa): conditioned inhibition.
Two experiments using garden snails (Helix aspersa) showed conditioned inhibition using both retardation and summation tests. Conditioned inhibition is a procedure by which a stimulus becomes a predictor of the absence of a relevant event--the unconditioned stimulus (US). Typically, conditioned inhibition consists of pairings between an initially neutral conditioned stimulus, CS(2), and an effe...
متن کاملSensory innervation of the ovotestis in the snail Helix aspersa.
Because oviposition in the land snail Helix aspersa is a metabolically expensive process coupled to a high fixed cost, one expects oviposition to occur only when the clutch size surpasses a minimum value at which the reproductive benefit exceeds the cost. We propose that neural innervation of the gonad allows H. aspersa to monitor oocyte production and ensure an adequate supply of gametes prior...
متن کاملUse of the Land Snail Helix aspersa as Sentinel Organism for Monitoring Ecotoxicologic Effects of Urban Pollution: An Integrated Approach
Atmospheric pollution from vehicular traffic is a matter of growing interest, often leading to temporary restrictions in urban areas. Although guidelines indicate limits for several parameters, the real toxicologic impacts remain largely unexplored in field conditions. In this study our aim was to validate an ecotoxicologic approach to evaluate both bioaccumulation and toxicologic effects cause...
