**Stellenbosch, South Africa -** A team of researchers from Stellenbosch University has discovered a promising new weapon in the fight against the destructive woolly apple aphid, a major pest threatening South Africa’s apple industry.

The team, led by Antoinette Paula Malan, Letodi Luki Mathulwe, and Nomakholwa Faith Stokwe, investigated the potential of entomopathogenic fungi – natural insect-killing fungi – for biocontrol of the woolly apple aphid. Their research, published in a recent academic article, revealed that three out of six tested fungi species proved highly effective at infecting and killing the aphids.

The researchers found that two of these fungi were particularly efficient, destroying the aphids within just five days. This is significantly faster than traditional methods, which typically take 7 to 14 days.

The research team is particularly excited about this discovery, as it marks the first time entomopathogenic fungi have been tested for use against the woolly apple aphid.

This discovery offers a potential solution to the growing problem of insecticide resistance in the apple industry. While chemical insecticides have been the primary method of control for decades, the woolly apple aphid has developed resistance, prompting a search for alternative approaches.

The researchers plan to conduct further testing under more natural conditions, including on apple trees grown in greenhouses and shade houses. They also intend to explore mass production and formulation techniques to make these fungi commercially viable.

“Ultimately, we hope to collaborate with local commercial companies to mass-produce these specific fungal species,” said Dr. Malan. “This would be a significant step towards helping apple growers control the woolly apple aphid, reducing insecticide resistance, and minimizing environmental pollution from chemicals.”

This research holds great promise for the South African apple industry, offering a potential solution to a long-standing problem and paving the way for more sustainable pest management practices.
