Climate-specific dynamics of fall armyworm on maize: Implications for pest monitoring and management

Although management methods for the fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae), have been explored, monitoring and surveillance in newly invaded regions is problematic. This study investigates the population dynamics and infestation levels of the fall armyworm (FAW), Spodoptera frugiperda, on maize farms in Togo's Guinean and Sudanese climatic zones to improve pest management strategies. Male FAW moths were monitored using pheromone traps over 15 months, and larval densities and plant damage were assessed on 100 maize plants per farm. Results revealed higher moth captures in the Sudanese than Guinean climate zones (2.77 ± 0.16 vs. 2.05 ± 0.13). During the major rainy season (June to August), captures peaked in the Sudanese zone (5.28 ± 0.52) compared to the Guinean zone (3.77 ± 0.55). No significant differences were observed during the minor rainy season (September to November), while dry season (December to May) captures were higher in the Guinean zone (0.54 ± ..., Distribution of sites and characteristics of study zones
Over 15 months, adult FAW were trapped at 15 maize sites distributed across the Guinean and Sudanese climatic regions of Togo (Fig. 1). During the maize seasons, the sites were expanded to three farms per site, including an on-station experiment within each climatic region, or 45 farms across the country for larval severity data collection.
The Guinean climate covers the three agro-ecological zones (AEZs) of southern Togo and is characterized by bimodal rainy seasons. The first rainy season marks the main maize season from April to July and the second covers the minor maize season from September to November. The two rainy seasons are separated by a short dry season of one month in August, while the main dry season lasts from December to March. The three AEZs of Togo's Guinean climate region include AEZ5 of the southern mosaic coastal savannah mixed with a relic forest and fallow land, AEZ4 of the western mountainous dense and semi..., , # Climate-specific dynamics of fall armyworm on maize: Implications for pest monitoring and management
