Schistosomiasis is a tropical disease caused by Schistosoma and occurs in 54 countries, mainly in South America, the Caribbean region, Africa and the eastern Mediterranean. Currently, 5 to 6 million Brazilian people are infected and 30,000 are under infection risk. Typical of poor regions, this disease is associated with the lack of basic sanitation and very frequently to the use of contaminated water in agriculture, housework and leisure. One of the most efficient methods of controlling the disease is application of molluscicides to eliminate or to reduce the population of the intermediate host snail Biomphalaria glabrata. Studies on molluscicidal activity of plant extracts have been stimulated by issues such as environmental preservation, high cost and recurrent resistance of snails to synthetic molluscicides. The aim of this study was to determine the molluscicide action of extracts from Piperaceae species on adult and embryonic stages of B. glabrata. Fifteen extracts from 13 Piperaceae species were obtained from stems, leaves and roots. Toxicity of extracts was evaluated against snails at two different concentrations (500 and 100 ppm) and those causing 100% mortality at 100 ppm concentration were selected to obtain the LC 90 (lethal concentration of 90% mortality). Piper aduncum, P. crassinervium, P. cuyabanum, P. diospyrifolium and P. hostmannianum gave 100% mortality of adult snails at concentrations ranging from 10 to 60 ppm. These extracts were also assayed on embryonic stages of B. glabrata and those from P. cuyabanum and P. hostmannianum showed 100% ovicidal action at 20 ppm.

“…It was introduced in Brazil with the purpose of fencing in gardens. It is popularly known as "Coroa de Cristo" (Crown of Thornes), "Coroa de Nossa Senhora" (Our Lady's crown), "Duas amigas" (Two friends), "Colchão de noiva" (Bride's mattress) and "Martírios" (Martyrs) (Pio Corrêa 1984) being one more plant among 360 to be tested for molluscicidal properties in Brazil (Jurberg et al 1989).…”

“…(Mott, 1987;Vasconcellos et al, 2003;Mello-Silva et al, 2007, 2010, 2011. According to Baptista et al (1994), and as noted by Kloos and McCullough (1987), Kuo (1987) and Jurberg et al (1989), it is estimated that 1426 plant species with molluscicidal properties have been analyzed to date. One of the most promising is the species Euphorbia splendens var.…”

The genus Physa are among the most common and widespread fresh-water snails and are frequently associated with the genus Lymnaea and Biomphalaria, typically occupying the same habitat and being hosts of trematodes that can cause disease in humans. Several studies have evaluated the control of snails through the use of plant-derived molluscicides; however, few such studies exist regarding the genus Physa. Determining the correct lethal doses of [latex of Euphorbia splendens] is important for the control of the Physa cubensis snail. In one experimental model, 150 snails from Jacarepaguá, Rio de Janeiro, RJ were used. After acclimatization for 72 hours, the snails were divided into groups of 10 and placed into beakers containing different doses, each at a temperature of 26±1ºC and a relative humidity of 80±10%. The results demonstrated LD 50 of 1.08 µL/L and LD 90 of 3.41 µL/L, without significant changes in the physical or chemical parameters of the solutions. We conclude that E. splendens latex had a significant effect on P. cubensis in the laboratory setting.
