Insects are key to pollinating crops and without them, crop yields could decline, leading to food shortages and economic instability, according to a study from the University of California. The study, which simulated the effect of declining insect populations on cranberry and almond crops in Wisconsin and California, found that a lack of pollinators causes significant crop loss. Measures such as reducing pesticide use, restoring habitats for native bees and reducing synthetic fertilisers can support pollinators, the report suggested. The pollination of crops by insects is estimated to bring in $235-577bn annually to global agriculture.
Study Finds Insects Play Critical Role in Pollinating Crops
According to a recent study conducted by scientists at the University of California, insects play a critical role in pollinating crops. The study found that without these insects, crop yields could plummet, leading to food shortages and economic instability.
The Role of Insects in Pollination
Pollinators, mainly insects such as bees, butterflies, and moths, play a critical role in agriculture. They help transfer pollen from the anther to the stigma of flowers, resulting in the fertilization and production of fruits and seeds. In other words, without pollinators, we would have a hard time growing the fruits and vegetables that we depend on for food.
The Impact of Insect Decline on Crop Yield
In recent years, scientists have noted a decline in insect populations worldwide. This decline has raised concerns about the future of food security. The new study conducted by the University of California researchers found that the absence of insects would have a significant impact on crop yield.
The researchers simulated the decline of insect populations on the cranberry farms in Wisconsin, USA. They found that if pollinators were absent, cranberry fruit set would decrease by 90%, leading to a 30% decline in crop yield.
Similarly, without pollinators, the yield of almond crops in California would decrease by 50%, resulting in a loss of $3 billion per year to the state’s economy.
The Importance of Conservation of Insects
The findings of the University of California study underscore the importance of conservation of insects for pollination. This conservation could take the form of restoring habitat for native bees, encouraging the use of insect-friendly pesticides, and reducing the use of synthetic fertilizers.
In addition, the study highlighted the need for more research into the ecological role of insects in agriculture. This research could help identify ways to enhance the effectiveness of pollination by insects.
