White Nose Syndrome
White Nose Syndrome
A fungal disease affecting bats, caused by Pseudogymnoascus destructans, a fungus from the Ascomycota phylum. It causes mass mortality in hibernating bats in North America.
Impact on Fruit Trees
Impact on Fruit Trees
Over 300 fruit trees rely on bats for pollination, including important crops like mangoes, bananas, and guavas. The White Nose Syndrome poses a threat to these fruit trees.
Insect Population Control
Insect Population Control
Bats play a crucial role in controlling insect populations, which helps to maintain ecological balance and protect crops from pests. The decline of bats due to White Nose Syndrome could lead to an imbalance.

Study Notes
Fungi in Agriculture and Food Industry
- Fungi play a crucial role in agriculture and food production, both beneficial and detrimental.
- White Nose Syndrome (WNS) is a devastating fungal disease affecting bats, causing mortality rates of 70-100% in infected hibernacula. The pathogen is Pseudogymnoascus destructans.
- More than 300 fruit trees rely on bats for pollination, including mangoes, bananas, and guavas.
- Loss of bats due to WNS impacts agriculture, as bats are natural insect controllers.
- Monoculture farming practices increase susceptibility to fungal infections.
- Bananas are a classic example; Fusarium oxysporum (TR1) caused a significant decline in the Gros Michel banana variety in the mid-20th century. The fungus spread globally and caused devastating losses
Monoculture and Fungal Infections
- Monoculture removes genetic diversity, making crops more vulnerable to fungal pathogens.
- Puccinia graminis (wheat rust) is a fungus that thrives in monoculture settings and caused significant wheat crop losses.
- Crop losses to fungal infections can reach $10 billion annually, a huge concern for food production.
- Botrytis cinerea, "noble rot", causes problems through both decay and desirable flavor development in wine grapes, resulting in significant crop loss in many locations.
Mycorrhizal Fungi
- Mycorrhizae refer to a symbiotic relationship between plants and fungi. The relationship is ancient, dating back 450 million years.
- 80 per cent of plants form mycorrhizal associations with fungi.
- Mycorrhizae dramatically improves plant uptake of minerals (especially nitrogen and phosphorous) and water.
- Different types of mycorrhizae include: Arbuscular, Ectomycorrhizae, Orchid, and Ericoid, each specializing in different plant types.
Fungi in Cheese Production
- Penicillium roqueforti is crucial for the maturation of blue cheese (like Roquefort).
- The fungus produces enzymes that break down milk proteins and lipids, generating characteristic flavors.
- The diversity of fungal species used in cheese production continues to evolve with new varieties appearing in the market frequently
Other notes
- WNS has not spread to Europe.
- Current efforts in crop improvement, and breeding new varieties and using antifungals, are helping to mitigate crop loss to fungal infections.
- Harvests also need protection from fungal contamination.
- Fungi play a significant role in a wide range of food production across many different types of products.
