“…The apple snail Pomacea canaliculata (often referred to as the golden apple snail in Southeast Asia) was introduced to Japan and many other countries in Southeast Asia in the early 1980s 4,5,10,14 . This fresh water snail from South America was initially introduced to Asia as a source of human food.…”

The apple snail Pomacea canaliculata becomes a much more serious pest in direct-sown rice fields than in transplanted fields. In south Japan, it represents an important constraint on the implementation of direct seeding. Described here are possible measures to control the snails and suggestions for its management in Japanese direct-sown rice fields. Crop rotation with upland crops is a practical way with the lowest extra cost. The apple snails were often not eradicated by growing an upland crop in the previous summer. However, snail densities always decreased below the control threshold in directsown fields (0.5 snails/m 2 ). Longer drainage period after sowing greatly reduced snail damage. Thus, draining fields for 10 to 20 days after sowing is a basic practice to control snails in direct seeding. Tillage and puddling have a function to crush snails and, thus, reduce snail densities. "Intensive tillage", in which a field with compacted hard soil is tilled shallow with faster cultivator rotation, achieved higher snail mortality. It is recommended to lower the risk of snail damage after unexpected heavy rain. An application of bait type metaldehyde showed enough control effects to avoid rice damage by snails even in heavy rain conditions. The stable effects seemed to be due to the active ingredient in the bait type which is dissolved slowly. Improving techniques for weeding and for draining fields effectively are necessary for better snail management in direct seeding.

“…The yield loss caused by GAS in rice was estimated varying from 5 % to 100 % depending on locality and the level of infestation in most Asian countries (Halwart, 1994;Naylor, 1996). In China, GAS was first introduced into Guangdong province in 1981and became a serious pest of rice since 1984 (Halwart, 1994). The first record for GAS infestation on rice and Zizania latifolia in Yuyao City of Zhejiang province was found in 2002, and became a serious pest in rice and Z. latifolia fields in 2004 (Pan et al, 2008).…”

The wild rice, Zizania latifolia Turcz, used to be one of the important aquatic vegetables cultivated in China. Recently, the golden apple snail -GAS (Pomacea canaliculata (Lamarck)) was found to be a major invasive pest attacking Z. latifolia. To control efficiently GAS, predation by the Chinese soft-shelled turtles (Pelodiscus sinensis) on GAS was evaluated in laboratory and field trials. P. sinensis had a strong predatory capacity and selectivity for GAS both in laboratory and field conditions. All the sizes of P. sinensis prefer to capture smaller snails. The optimum number of P. sinensis released in Z. latifolia field was dependent on the density of over-wintered GAS, and varied between 30 and 50 turtles per 666.7 m 2 . The number of GAS declined in the fields with turtles as compared to turtle-free field. A pattern of releasing P. sinensis in Z. latifolia fields was developed and widely adopted by farmers because of much more benefit besides biologically controlling GAS.

“…The snails were released uncontrolled to rivers, and they later spread into rice fields where they have become a serious threat to rice production, as they can consume an entire paddy field of young rice plants overnight. Consequentially, synthetic molluscicides (e.g., CuSO 4 , metaldehyde, and niclosamide) are widely used to control snail populations in rice fields 8 . These broad acting non-specific molluscicidal agents are however extremely toxic to non-target organisms, including humans and to the environment in addition to adding considerable costs to the farmers 9 .…”

A mixture of molluscicidal saponin compounds was isolated from a methanolic extract of seed meal of Camellia oleifera and tested against Pomacea canaliculata. The most potent saponin fraction showed an LC50 value of 0.66 ppm. This was then used as a marker for quantitative analysis of active molluscicidal compounds in commercial oilseed camellia meals on HPLC fractionation. The active saponin content was found to be 0.25-1.26% w/w. Methanol was the preferred extraction solvent for analysis of saponin compounds from oil-seed camellia meal. The effect of oil-seed camellia meal on P. canaliculata in a field experiment was determined for three doses: 12.50, 15.63, and 18.75 kg/ha in terms of numbers of dead snails. After one day, all treatments containing oil-seed camellia meal killed 100% of the snails in the sample compared with just 3.8% in the control without any chemical additive. No rice plant damage was detected from any treatments with oil-seed camellia meal, and the dry grain yield was comparable to that of niclosamide treatment. Thus oil-seed camellia meals may be a useful molluscicide for organic rice production.
