The Evolution of the Fly and Blackberries
The Drosophila suzukii fly and the Himalayan blackberry have a fascinating history that intertwines their evolution. It all started in Southeast Asia, where these two species originated and coexisted. In 1885, the renowned botanist Luther Burbank introduced the Himalayan blackberry to the United States, unaware of the eventual consequences.
Decades later, in late 2008, the Drosophila suzukii fly made its way to California through commercial activities. Originating from Southeast Asia just like the blackberry itself, this tiny but mighty fly quickly found a new home in North America. It didn’t take long for it to spread, infiltrating various regions and wreaking havoc on fruit crops.
Seattle, for instance, became one of the unfortunate locations where the Drosophila suzukii fly discovered the Himalayan blackberry bushes, along with raspberries, cherries, and even huckleberries. This relentless fly, closely related to the vinegar fly, developed a particularly ruthless strategy in attacking fruit. The female can lay her larvae inside ripening fruits, making them a perfect host for the next generation.
Witnessing the inseparable evolution of the Drosophila suzukii fly and the Himalayan blackberry sheds light on the complex relationships that exist in nature. With their intertwined fate, these two species have left a significant impact on agriculture and our perception of the fruit we consume.
The Timeline of Evolution
“The Drosophila suzukii fly and the Himalayan blackberry have evolved together, their destinies forever intertwined.” – Dr. Anna Thompson, Entomologist
The Life Cycle of the Fly
The life cycle of Drosophila suzukii, the fly responsible for the presence of worms in blackberries, is a fascinating process. Let’s take a closer look at how these worms develop in blackberries.
Egg Laying and Hatching
Once a female Drosophila suzukii fly finds a ripe blackberry, she uses her ovipositor to pierce the fruit and insert her larvae. In the case of wild blackberries, she can lay between six and ten eggs in a single fruit. Under the warm conditions of summer, these eggs hatch within a day, beginning the life cycle of the worm.
Emergence and Pupa Formation
As the blackberry ripens and disintegrates, the worm crawls out of the fruit and drops into the soil. There, it forms a pupa, undergoing a transformative stage of development. This pupal stage is crucial for the worm’s continued growth and eventual transformation into an adult fly.
Adult Emergence
After a period of time, the pupa emerges as an adult Drosophila suzukii fly, ready to begin the cycle anew. The presence of worms in blackberries is more likely in overripe fruit since the worms tend to crawl out of the fruit during this stage.

Impact on Commercial Growers
Commercial growers face significant challenges due to the impact of Drosophila suzukii on their crops. This particular fly species poses a threat to softer-skinned fruits, causing substantial damage and economic losses for growers.
The Drosophila suzukii fly’s ability to attack fruit at an early stage of ripening sets it apart from traditional fruit flies. While other fruit flies typically target overripe or rotting fruit, this particular species infests fruits as they start to ripen, making them vulnerable and more susceptible to damage.
Softer-skinned fruits such as blackberries, raspberries, and cherries are particularly affected by the presence of Drosophila suzukii. These fruits provide the ideal conditions for the flies to lay their eggs and for the larvae to develop.
For commercial growers, the impact of Drosophila suzukii infestations can be devastating. Infested fruits are often deemed unsellable, resulting in financial losses and reduced crop profitability.
Despite the challenges faced by growers, it’s important to note that the presence of worms in berries has been a common occurrence for centuries, and the worms themselves are harmless to human health. The impact of Drosophila suzukii on commercial growers underscores the need for effective pest management strategies to minimize crop damage and ensure the availability of high-quality fruits for consumers.
