Traps deployed to combat armyworm surge

Following a surge in African armyworm moth, authorities have deployed 214 traps across rural provinces to combat the scourge.

The establishment of this early warning system is a crucial step in combating the threat posed by the destructive pest.

In his weekly report, the Agricultural and Rural Development Advisory Services (ARDAS) chief director, Mr Leonard Munamati, reported significant moth captures particularly in Mashonaland Central, Midlands, and Matabeleland North provinces.

 “Crops are vulnerable to these African armyworms. They move in great numbers, and once they feed on the whole plant, there is no possibility of regrowing,” he said.

This urgency is underscored by the department’s ongoing monitoring of fall armyworm population, especially in irrigation schemes.

Affected areas include Shamva with 38 traps, Mt Darwin with 29, Rushinga with 25, and Mbire with 15 in Mashonaland Central. Additionally, Gokwe District in the Midlands Province reported 48 captures, while Umguza District in Matabeleland North recorded 135.

The presence of these pests has raised concerns over crop yields and food security. The African armyworm is known for its destructive feeding habits.

 Reports indicate severe damage to various crops: sweet potatoes are experiencing compromised leaf health and stunted tuber growth; tomatoes are facing serious defoliation; and both sweet and hot peppers exhibit damage similar to that seen in tomatoes.

Tobacco farms are not exempt, with heavy feeding leading to significant leaf damage.

To address this escalating threat, the department has dispatched chemicals to Mashonaland Central and is organising supplies for other provinces at risk.

 “There are enough chemicals to control the pests. Farmers should report infestations promptly and they should be scouting on a daily basis to avoid losses,”

 Tobacco Farmers’ Union Trust president Mr Victor Mariranyika said there is need for awareness and education campaigns.

“Farmers should be educated; hence awareness programmes are effective when dealing with such issues. Agritex officers should also be working with farmers in identifying areas where African armyworms habitate,” he said.

 He commended the Government’s efforts to secure sufficient chemicals.

The African armyworm, a common pest in Southern Africa, originates from regions such as Zambia, Uganda, and Tanzania.

Carried by strong winds, these moths can travel long distances and are easily identified by their dark brown wings adorned with black spots.

Experts note that they thrive in humid areas and reproduce rapidly, which complicates efforts to manage their population.

“Regular monitoring and the use of pesticides are recommended,” said Mr Munamati.
