“…For example, deep-water rice is rarely affected by pests other than stem borers (Catling, 1992). However, deep-water rice is severely hampered in regions where apple snails have been introduced (Horgan et al, 2014b). Because deep-water rice is produced in environmentally vulnerable areas, it constitutes an important habitat for wildlife including fish, amphibians, reptiles and birds (Catling, 1992).…”

“…Several recent surveys of rice farmers in Asia also indicate a high level of pesticide use and little recourse to alternative pest control methods (Rejesus et al, 2012;Qiao et al, 2012;Abdollahzadeh et al, 2015). Paradoxically, the trend towards an increasing availability of chemical pesticides has not resulted in the expected lower pest and weed incidences, but to area-wide problems of resistant weeds (Powles and Shaner, 2001), sustained outbreaks of planthoppers and leaf folders (Crambidae) (Sprangenberg et al, 2015;Chintalapati et al, 2016), unstable management of snails (Horgan et al, 2014b) and worrisome consequences for environmental and human health (Pingali and Roger, 1995;Qiao et al, 2012), often without clear yield responses to chemical inputs (Pingali and Gerpacio, 1997;Sprangenberg et al, 2015).…”

“…These studies have focused not only on a range of insecticides, but also on molluscicides, fungicides and herbicides that increase herbivore fitness (e.g. Grigarick et al, 1990;Wu et al, 2001;Wang et al, 2005;Assam et al, 2009;Xin et al, 2012;Horgan et al, 2014b).…”

“…In fields treated with molluscicides in tropical Asia, surviving apple snails can grow rapidly, due to reduced intraspecific competition, representing a more serious threat to developing rice plants than untreated rice plots that have high-density snail populations but smaller individuals (Horgan, 2017). Farmer surveys in Ecuador have indicated that fields treated with molluscicides may also have a greater propensity for insect damage (Horgan et al, 2014b).…”

“…In some riceproducing regions, rice farmers adopt crop management practices specifically aimed at conserving wetland birds (Elphick and Oring 2003;Elphick et al 2010). The diversity of birds and their beneficial activities can be promoted by enhancing structural diversity in rice fields [i.e., providing perches or setting aside habitat for kites (Horgan et al 2014) or providing nest boxes for owls (Hafidzi and Na'im 2000)]. Because HDVPs also increased the structural diversity of rice fields, we predicted that bird abundance and activities would be promoted by this form of ecological engineering.…”

This study examines the potential for ecological engineering to enhance the beneficial ecosystem services provided by birds in tropical rice fields. Bird activities were monitored at six sites in the Philippines with high-diversity vegetation patches (HDVPs) established as an ecological engineering approach to restore ecosystem services. Adjacent plots of conventional rice were monitored as controls. Predatory birds (shrikes, Lanius spp., grassbirds, Megalurus palustris, and kingfishers, Halcyon spp.) were more active in the ecological engineering fields where they foraged for arthropods and snails among the rice plants. Pied trillers, Lalage nigra, and yellow vented bulbuls, Pycnonotus goiavier, foraged more in the HDVPs than in rice. These birds mainly responded to the availability of bamboo for perching in the HDVPs, although patch vegetation beneath the bamboo was also used for perching by some species. Aerial hunters such as swallows, Hirundo spp., avoided HDVPs likely because the tall vegetation and bamboo stakes represented an obstacle for their flight. Small changes in the design of HDVPs could avoid any negative effects on foraging by swallows and swifts. The results indicate that ecological engineering of rice paddies can have multiple benefits for farmers and the environment, including improved nutrition for farming communities, the creation of habitat for wildlife, and the enhancement of regulatory ecosystem services provided by insectivorous and snail-eating birds.

A native bird as a predator for the invasive apple snail, a novel rice field invader in Europe

1. Since 2009 the apple snail Pomacea maculata has become a new invader of Oryza sativa (rice) fields and wetlands in Europe, only invading the Ebro Delta (northeastern Spain) thus far. It is considered a highly invasive and damaging species, resulting in large economic losses worldwide.2. Despite the severe impact of the invasive apple snail on both cultivated and natural wetlands, it has become an abundant potential resource for native avian predators.3. In this study, stable isotope analysis was used to assess the consumption of the apple snail by the glossy ibis Plegadis falcinellus in the Ebro Delta. 4.The results indicate the importance of the apple snail in the diet of this native bird. In particular, isotopic results indicated that apple snails and freshwater coleopterans were the main prey in the diet of glossy ibis chicks, accounting for 26-40% of their diet. Thus, this native bird species could potentially help in the biological control of this invasive snail, but is not expected to eradicate it. 5. Although the spread of this pest in rice fields and wetlands is not desirable, we predict that the apple snail will follow a path similar to other invasive species, such as the red swamp crayfish Procambarus clarkii, in establishing itself as part of the wetland food web.
