“…The African armyworm, Spodoptera exempta (Walker, 1856) (Lepidoptera: Noctuidae), is an episodic crop pest and the most potentially serious hazard among migratory pests in Africa (Brown and Swaine, 1966;Pringle 1980;Redman et al 2010). Mass oviposition of S. exempta results in the initiation of larval outbreaks, which can cause severe damage to rangeland grasses and crops, including maize, millet, rice, wheat, among others Gatehouse 1985a, 1985b;Xu et al 2020).…”

The African armyworm, Spodoptera exempta , is an episodic migratory crop pest with an expanding distribution worldwide. This is the first report of the circular mitochondrial genome of S. exempta , with a length of 15,457 bp and an A + T content of 81.7%. It encoded a common set of 37 genes, including 13 protein-coding genes (PCGs), 22 tRNA genes, and two rRNA genes, and contained a putative control region of 379 bp (94.7% in A + T proportion). The maximum-likelihood phylogenetic tree based on the complete mitogenome demonstrated that five species belonging to the Spodoptera genus formed one clade, in which S. exempta was the most isolated branch, followed by Spodoptera exigua . This data will contribute for the identification and phylogenetic analyses of S. exempta , providing useful information for its comprehensive control.

“…The African armyworm, Spodoptera exempta, is a sporadic but harmful pest of pastures and graminaceous crops in East Africa. The species has attracted scientific interest mainly with respect to its population dynamics (see review by Pringle, 1980). Little is known, however, about its pheromone biology, a subject extensively studied in some other Spodoptera species (for a review see Campion, 1975).…”

Sensilla trichodea, with porous walls and two receptor cells, are the most abundant sensiila on the antennae of male Spodoptera exempta. Two synthetic pheromone components, Z-9-tetradecen-l-yl acetate (Z-9-TDA) and Z-9,E-12-tetradecadien-l-yl acetate (Z-9,E-12-TDDA), produced identical electroantennogram (EAG) responses with male antennae, and strong stimuli of either compound were found to adapt the response to the other compound. When nerve impulses were recorded from single sensilla trichodea, Z-9,E-12-TDDA usually was the key stimulus, Z-9-TDA being over hundred times less effective, but some receptor cells were equally sensitive to both compounds. The female pheromone gland was located in the ventral intersegmental membrane between the 8th and 9th abdominal segment. Measured by male EAG responses, the crude hexane extract of one female gland, on the average, was equivalent to 5 ng of Z-9-TDA or Z-9,E-12-TDDA. Individual variation, however, was extreme even between females of the same lot and age, and there were no significant differences in pheromone content between females of different age and physiological conditions. KEY WORDS: Spodoptera exempta --Lepidoptera --Noctuidae --Sex pheromone --Electroantennogram --Sensilla trichodea --Pheromone gland.
