Armyworm Outbreak Ravages Zimbabwe, Threatening National Food Security

Harare, Zimbabwe – March 3, 2025 – Zimbabwe is battling a severe and rapidly spreading outbreak of the African armyworm, with infestations now reported across 30 districts spanning all 10 provinces. This destructive pest, known for its voracious appetite and swift propagation, poses a grave threat to the nation’s staple crops, including maize, wheat, and soybeans, jeopardizing national food security.

The crisis, first detected on December 31, 2024, has escalated alarmingly, highlighting the formidable nature of the African armyworm (Spodoptera exempta). This pest is notorious for its ability to decimate vast swathes of foliage in a remarkably short period. The current rainy season, typically running from December to April, provides ideal conditions for the armyworm to thrive, as seasonal winds facilitate its rapid spread across the country.

In response to the escalating crisis, the government has distributed over 220 kilograms of pesticides as of late February 2025, aiming to assist affected farmers in combating the infestation. The Ministry of Lands, Agriculture, Fisheries, Water, and Rural Development is urging farmers to remain vigilant and promptly report any further infestations. Agricultural experts emphasize that early detection and swift intervention are crucial to preventing further crop damage and containing the pest’s spread.

The African armyworm’s life cycle contributes to its rapid expansion, with a single female moth capable of laying between 1,000 and 1,300 eggs. This prolific reproduction leads to sudden population explosions if left unchecked. Farmers in the affected areas are deeply concerned, particularly as many crops are still in their vulnerable early growth stages.

The Zimbabwe Farmers’ Union has issued urgent advisories, urging farmers to implement preventive measures such as frequent crop inspections and timely pesticide applications. Additionally, experts recommend integrating biological control methods, including promoting natural predators like birds and beneficial insects, to help suppress the armyworm population.

Authorities have reassured farmers that concerted efforts to contain the outbreak are ongoing. Further pesticide distributions and widespread awareness campaigns are planned for the coming weeks to mitigate the situation. However, with the peak growing season underway, continuous monitoring and decisive action are essential to minimizing losses and safeguarding food security for millions of Zimbabweans.
