The tiny invasive snail is called the rosy wolf snail (Euglandina rosea). It is native to Florida and the Caribbean, but it has been introduced to many other parts of the world, including Latin America. The rosy wolf snail preys on other snails, including the giant African land snail (Achatina fulica), which is a major pest of coffee plants. The giant African land snail can cause extensive damage to coffee plantations, and it can also transmit diseases to humans. The rosy wolf snail has been shown to be effective in controlling the giant African land snail, and it has therefore been used as a biological control agent in Latin America.

Studies have shown that the rosy wolf snail can reduce the abundance of the giant African land snail by up to 90%. This has led to increased coffee yields and reduced economic losses for coffee farmers in Latin America. The rosy wolf snail has also been shown to be a sustainable biological control agent, as it is able to maintain its population size and control the giant African land snail population over time.

The introduction of the rosy wolf snail to Latin America has been a successful example of biological control. It has helped to reduce the damage caused by the giant African land snail, and it has improved the livelihoods of coffee farmers.
