The study was conducted to assess the effect of Zingiber officinale and Carica papaya extract on the egg hatchability of the golden apple snail, Pomacea canaliculata. This is a freshwater snail that is considered a pest in agriculture as well as natural ecosystems. In combating the population of the aforementioned pest, this study evaluates the use of plant extracts such as biomolluscicides to control the production of new hatchlings from the clusters of eggs. The egg clusters were exposed to different concentrations of Z. officinale ethanolic extract and C. papaya methanolic extracts (25 ppm, 50 ppm, 100 ppm) using the direct single spraying method. Observation was made for a maximum of 30 days. The time taken for the eggs to hatch and the number of eggs successfully hatched were measured to reflect the potential of both extracts in affecting egg hatchability. The finding shows that the eggs hatch later when exposed to increasing concentrations (25 to 100 ppm) of Z. officinale extract. The number of eggs successfully hatched was significantly decreased from 86% to 9% after exposure to 25 ppm and above. Meanwhile, the extract of C. papaya did not show any significant effect on both parameters for egg hatchability of P. canaliculata, regardless of the increase in concentration from 25 to 100 ppm. Our findings reveal that the extract of Z. officinale contains higher molluscicidal activity than the extract of C. papaya. Therefore, it has the potential to be commercialized as a biomolluscicide to control the population of golden apple snails specifically at the egg stage.

Abstract P. maculata is a freshwater snail native to a wide geographical area in South America from the Rio de la Plata in Argentina and Uruguay to the Amazon in Brazil. It is commonly confused with any number of similar large apple snails, including the well-known invasive golden apple snail Pomacea canaliculata (listed among '100 of the world's worst invasive species'). Both species have been introduced to South-East and East Asia, although for many years they were not distinguished and the Asian introductions were widely identified as "golden apple snails" and the name P. canaliculata was applied to them. Due to the confusion in species identification, the history of introduction of P. maculata remains somewhat uncertain as does its invasiveness and pest potential. Much of the literature is confounded, for example, the snails illustrated by Cowie (2002) as P. canaliculata are in fact P. maculata. The majority of invasive populations in Asia appear to be P. canaliculata, often not mixed with P. maculata (Hayes et al., 2008; Tran et al., 2008) and the pest potential of P. canaliculata in such cases is clear. However, much less has been written about the invasiveness and pest potential of 'P. maculata'.

This study was conducted to investigate the molluscicidal activity of four different Ipomoea batatas (I. batatas) leaf extracts (hexane, chloroform, methanol, and aqueous extracts) against Pomacea canaliculata (P. canaliculata) and screen the phytochemical compounds of I. batatas leaf extracts. The golden apple snails (size range: 20–40 mm) were exposed to three concentrations (1000, 5000, and 10,000 ppm) of each extract (hexane, chloroform, methanol, and aqueous extracts). The efficacy of the I. batatas extracts was laboratory-tested by submerging the P. canaliculata into paddy-filled water mixed with the extracts and the mortality was observed every 24 hrs for 3 days. The presence of phytochemical compounds such as terpenoids, flavonoids, saponins, tannins, alkaloids, and glycosides were tested. For all extracts, the results showed a positive relationship between the concentration and the golden apple snail mortality, suggesting that all extracts have molluscicidal properties. The study showed more than 50% mortality rate of P. canaliculata after 72 hrs for each treatment. Chloroform and methanol I. batatas leaf extracts at 10,000 ppm showed 100% mortality after 72 hrs due to the presence of saponin. Saponin causes the death of the snails by disturbing their feeding and growth and blocking their breathing process. For further research, it is suggested to conduct the study under field trials in the search for a natural and environment-friendly molluscicide.

<em>The golden apple snail, (Pomaceae canaliculata Lamarck) is a freshwater snail having been widely distributed thoughout Indonesia since its introduction from South America.&nbsp; This snail has been a serious rice pest problem in Prafi district because it damages young rice seedling.&nbsp; The present research was carried out to study the population density of the snail at four different habitats in Prafi district of Manokwari.&nbsp; The data collection was taken place in the villages of Prafi Mulya, Aimasi, Desay and Udapi Hilir during one month period.&nbsp; Result of the present research indicated that the population density of the golden apple snail found in the observed four different habitats in Prafi district which were irrigation canal, river, paddy field and pod were&nbsp; 0.38, 8.17, 24.75 and 33.79 ind/m<sup>2</sup>, respectively.</em>

Abstract P. canaliculata is a freshwater snail native to parts of Argentina and Uruguay. The distribution of P. canaliculata has been steadily increasing since its introduction to Asia, primarily as a human food resource but perhaps also by the aquarium trade, beginning around 1979 or 1980 (Mochida, 1991; Halwart, 1994a; Cowie, 2002; Joshi and Sebastian, 2006). Once introduced to an area, it spreads rapidly through bodies of water such as canals and rivers and during floods. It feeds on aquatic plants and can devastate rice (in South-east Asia), taro (in Hawaii) and other aquatic or semi-aquatic crops. It may out-compete native apple snails (Halwart, 1994a; Warren, 1997), prey on native fauna (Wood et al., 2005, 2006) and alter natural ecosystem function (Carlsson et al. 2004a). It is also an important vector of various parasites including the nematode Angiostrongyulus cantonensis, which causes human eosinophillic meningitis (Lv et al., 2011; Yang et al., 2013).It is listed among '100 of the world's worst invasive species' (Lowe et al., 2000). In the United States its transport between states is restricted (Gaston, 2006), as is its transport between islands in the Hawaiian archipelago (Tamaru et al., 2006). It is listed as a quarantine pest in Malaysia (Yahaya et al., 2006) and in Japan. Australia has strong quarantine restrictions and is particularly concerned about P. canaliculata (Cowie, 2005).

Pomacea canaliculata (known as invasive apple snail) is a freshwater snail native to South America that was introduced into many countries (including Asia and North America) as a food source or for organic farming systems. However, it has invaded freshwater ecosystems and become a serious agricultural pest in paddy fields. Water temperature is an important factor determining behavior and successful establishment in new areas. We examined the behavioral responses of P. canaliculata with water temperature changes from 25 °C to 30 °C, 20 °C, and 15 °C by quantifying changes in nine behaviors. At the acclimated temperature (25 °C), the mobility of P. canaliculata was low during the day, but high at night. Clinging behavior increased as the water temperature decreased from 25 °C to 20 °C or 15 °C. Conversely, ventilation and food consumption increased when the water temperature increased from 25 °C to 30 °C. A self-organizing map (an unsupervised artificial neural network) was used to classify the behavioral patterns into seven clusters at different water temperatures. These results suggest that the activity levels or certain behaviors of P. canaliculata vary with the water temperature conditions. Understanding the thermal biology of P. canaliculata may be crucial for managing this invasive snail.
