Bat houses help rice farmers in Spain

checking a bat houseWe would like to highlight a recent study of exceptional importance to all who care about conserving bats. As one who has long promoted the potential benefits of attracting bats to artificial roosts, Merlin is especially pleased with the publication of a recent multi-year study documenting the successful attraction of thousands of bats to small, inexpensive bat houses, leading to well documented reduction of rice pests below threshold levels that require use of chemical pesticides.

The study titled, Pest control service provided by bats in Mediterranean rice paddies, appeared in the journal Mammalian Biology and is available for free download at researchgate.net.

The researchers report that properly located bat houses were readily occupied by soprano pipistrelle bats (Pipistrellus pygmaeus), and that as numbers increased damage from rice borer moths (Chilo supressalis) fell sufficiently to eliminate further need for chemical pesticides. They additionally note that the cost of putting up bat houses was 6-8 times less than that of relying on chemical treatments. These authors also provide an invaluable summary of current knowledge of bat values to agriculture. There are numerous opportunities to expand on this pioneering research which is urgently needed. We deeply appreciate the help of Adrià López-Baucells and Oriol Massana Valeriano in providing outstanding photographic documentation of this project.
