“…Several studies (Coleman, Dreyer, & MacDonald, 2011;Roda et al, 2018;Minnot, Jagroo, & Ramdwar, 2018) have demonstrated the use of traps for the control of the giant African snail. Albeit, concentrated sodium chloride solution has been used as an effective method for controlling snails by dehydration effects and drowning, the current study demonstrated the effectiveness of low quantities of calcium hydroxide and copper sulphate which can be used in potential snail traps.…”

This study evaluated the immobilization and mortality effects of selected wet and dry chemical treatments on the giant African snail. The chemical treatments used were 5 g and 10 g respectively of sodium chloride, calcium hydroxide and copper sulphate. Distilled water was used as a control in the wet phase evaluation of the study. In the first phase, each treatment was dissolved in 1000 ml of water. A total of ten (10) snails were submerged into each treatment and this was replicated ten (10) times. In the second phase of the study, 5 g and 10 g respectively of each dry treatment was evenly sprinkled over ten (10) snails within a confined area. This was replicated ten (10) times. It was concluded that the submergence effects of the wet treatment resulted in 100 percent immobilization and mortality for both the calcium hydroxide and copper sulphate treatment at six (6) hours post submergence. The dry treatments had no effect on immobilization and mortality up to six (6) hours post treatment. There was no treatment effect of sodium chloride for both the wet and dry treatments. The study concludes that low cost solutions such as calcium hydroxide can have an effect on the immobilization of the giant African snail. This finding can enable the development of trap designs which could eliminate the one-way door design and enable multiple entrances. Although both calcium hydroxide and copper sulphate solutions were effective for the immobilization and death of the snails, calcium hydroxide is the recommended option given its low toxicological profile when compared to copper sulphate.

“…Food, agricultural waste products, and food grade essences have been tested with varying levels of effectiveness as attractants for GAS [10, 13, 15, 23–25]. Unlike food products, the chemical composition of synthetic lures remains consistent and does not rot, in contrast to aging food baits, which can attract ovipositing flies and vermin.…”

Synthetic chemical lures mimicking pheromones or food attractants are essential tools in eradication programs for invasive species. However, their uses in programs aiming to control or eradicate terrestrial gastropods are largely unexplored. The goal of this study was to find a synthetic attractant that could aid in the eradication or management of the giant African snail (Lissachatina fulica). Field studies in Hawaii showed that a commercial papaya-flavored oil attracted snails. Analysis of the odor profile of the oil identified a total of 22 chemicals, which comprised > 98% of the volatile compounds emitted by the oil. A synthetic blend was reconstructed that mirrored the release rates of the papaya oil odors. In laboratory and field bioassays, the reconstructed blend, applied to cotton wicks as water and canola oil or water and mineral emulsions, attracted more snails than the water and oil emulsion control wicks. Field studies in Hawaii and Florida showed that the reconstructed blend in an oil emulsion was not attractive to non-target species such as butterflies or bees. The snails were attracted from distances > 1 m and entered traps baited with the attractant emulsion. When tested in the South Florida giant African snail eradication program, direct ground application of the reconstructed papaya-flavored oil emulsion increased the number of snails killed by over 87% compared to water emulsion controls. Integrating tactics using the synthetic papaya oil attractant into control measures should increase the effectiveness of eradication and management programs.
