Insectivorous bat populations, adversely impacted by white-nose syndrome and wind turbines, may be worth billions of dollars to North American agriculture. White-nose syndrome (WNS) and the increased development of wind-power facilities are threatening populations of insectivorous bats in North America. Bats are voracious predators of nocturnal insects, including many crop and forest pests. We present here analyses suggesting that loss of bats in North America could lead to agricultural losses… 
On Estimating the Economic Value of Insectivorous Bats: Prospects and Priorities for Biologists
Bats are among the most economically important nondomesticated mammals in the world. They are well-known pollinators and seed dispersers, but crop pest suppression is probably the most valuable
Bats initiate vital agroecological interactions in corn
It is shown that bats exert sufficient pressure on crop pests to suppress larval densities and damage in this cosmopolitan crop, and it is estimated that the suppression of herbivory by insectivorous bats is worth more than 1 billion USD globally on this crop alone.
Ecological and Economic Importance of Bats (Order Chiroptera)
Bat populations appear to be declining presumably in response to human induced environmental stresses like habitat destruction and fragmentation, disturbance to caves, depletion of food resources, overhunter for bush meat and persecution, increased use of pesticides, infectious disease, and wind energy turbine.
Bats and Ecosystem Management
Bats are among the most misperceived and undervalued animals on the planet. For wildlife ecologists, they are wonderful and incredibly fascinating creatures, but people’s feelings about bats are
Insectivorous bat occupancy is mediated by drought and agricultural land use in a highly modified ecoregion
California's Central Valley, one of the most productive agricultural regions worldwide, is home to a high number of at‐risk species due to habitat conversion. Amplifying the issue, the Central Valley
Bats actively prey upon mosquitoes and other deleterious insects in rice paddies: Potential impact on human health and agriculture.
The results suggest that bats actively exploit the emergence of adult mosquitoes and further prove that they prey on mosquitoes, non-biting midges and other deleterious insects.


Economic value of the pest control service provided by Brazilian free-tailed bats in south-central Texas
Brazilian free-tailed bats (Tadarida brasiliensis) form enormous summer breeding colonies, mostly in caves and under bridges, in south-central Texas and northern Mexico. Their prey includes several
Bats Limit Insects in a Neotropical Agroforestry System
In a Mexican coffee plantation, bird and bat predators were excluded from coffee plants and it is concluded that previous "bird" exclosure experiments may have systematically underestimated the effects of bats.
Bats Limit Arthropods and Herbivory in a Tropical Forest
It is concluded that bats have dramatic ecological effects that were previously overlooked in a lowland tropical forest in Panama and measured the direct effects and indirect effects of bird predation from bat predation.
Brazilian free-tailed bats as insect pest regulators in transgenic and conventional cotton crops.
A dynamic model to predict regional-scale ecological functions in agricultural food webs is developed by using the indicators of insect pest herbivory measured by cotton boll damage and insect emigration from cotton to find that the agronomics of both Bt and conventional cotton production is more profitable when large numbers of insectivorous bats are present.
Food of the Big Brown Bat Eptesicus fuscus from Maternity Colonies in Indiana and Illinois
The insects most eaten by big brown bats in Indiana were agricultural pest species: scarab beetles, the spotted cucumber beetle, stinkbugs and leafhoppers, and Larvae of the genus Diabrotica are the corn rootworms, probably the single most important agricultural pest in the United States.
Wing pathology of white-nose syndrome in bats suggests life-threatening disruption of physiology
The unique physiological importance of wings to hibernating bats in relation to the damage caused by G. destructans is reviewed and it is proposed that mortality is caused by catastrophic disruption of wing-dependent physiological functions.
Bat Mortality at Wind Turbines in Northwestern Europe
We reviewed published and unpublished written reports on bat mortality at wind farms in northwestern Europe. The estimated number of bats killed per turbine annually was relatively low (0–3) on flat,
Feeding Strategies of the Little Brown Bat, Myotis Lucifugus, in Southern New Hampshire
It is suggested that increased resource availability allowed selective feeding in adult bats during July, as predicted by presy selection models, however, reduced discriminatory abilities may prevent similar levels of prey selection in juveniles.
The pollination ecology of two species of Parkia (Mimosaceae) in southern Thailand
Although the floral traits of Parkia conform to the bat-pollination syndrome, many visitors other than bats have been observed at their flowers; the syndrome is therefore best regarded as a hypothesis for which field observations and pollination experiments are required.
Could localized warm areas inside cold caves reduce mortality of hibernating bats affected by white-nose syndrome?
Evidence is presented that artificial warming of localized areas within hibernacula could increase survival of WNS-affected bats during winter by lessening the energetic costs of periodic arousals and could serve as a stopgap measure to slow population declines until a solution is found.
