“…Identified stem borers were grouped according to their respective host plants and vegetation mosaics for analysis of stem borer species diversity. Data of previously recorded stem borer species (Laporte, 1975(Laporte, , 1976Rougeot, 1984 andRougeot et al, 1991) were also included in an attempt to catalogue the diversity of the stem borer species in Ethiopia. Data from each vegetation mosaic were used to compute diversity indices described by Magurran (2005)…”

“…Despite the critical importance of natural habitats to stem borer pest dynamics (Ong'amo et al., ), previous studies in Ethiopia focused on the distribution, diversity (Assefa et al., ; Dejen, Getu, Azerefegn, & Ayalew, ; Gebre‐Amlak, ; Getu, Overholt, & Kairu, ; Tefera, ; Wale et al., ) and management of stem borer pest species in cultivated fields only (Belay & Foster, ; Belay, Schulthess, & Omwega, ; Gebre‐Amlak, Roland, & Jan, ; Getu et al., ; Tilahun & Azerefegn, ; Tsehaye, Getu, & Fininsa, ). Very few studies have been carried out on the lepidopteran stem borer fauna of the wild habitats in Ethiopia, and they include surveys on the ecology (Assefa, Conlong, & Mitchell, ; Le Ru, Ong'amo, Moyal, Ngala, et al., ) and systematics (Laporte, , ; Rougeot, ; Rougeot, Bourgogne, & Laporte, ). In the ecological surveys, 14 lepidopteran stem borer species belonging to the Noctuidae (nine species), Crambidae (one species), Pyralidae (two species) and Tortricidae (two species) were recovered from 14 host plant species belonging to Poaceae, Cyperaceae and Typhaceae.…”

The stem borer systematics on light trap collected specimens described a total of 26 noctuid species: five Sciomesa , five Sesamia (Laporte, , ; Rougeot, ; Rougeot et al., ) and 16 Acrapex species (Rougeot, ; Rougeot et al., ). However, these species were recently recombined or synonymized to Feraxinia, Sciomesa and Sesamia genera (Moyal et al., ), thus reducing the total number of species to eight.…”

Lepidopteran stem borers are among the most important insect pests of maize, sorghum and sugarcane in sub‐Saharan Africa. Except for Chilo partellus, the other stem borer pests in Ethiopia are indigenous to Africa and are assumed to have coevolved with some native grasses and sedges in the natural habitat. In addition to pest species, natural habitats harbour diverse non‐economic stem borer species, some of which are new to science. However, with the growing threats to natural habitats, some non‐economic stem borer species may switch or expand their host ranges to include cultivated crops and evolve as “new” pests. Besides host switch, some of the unknown species currently limited to natural habitats may disappear. We examined the diversity, abundance and interactions of lepidopteran stem borers and their wild host plants in five different vegetation mosaics in Ethiopia. The stem borer species diversity varied among vegetation mosaics and host plants. Forty‐four stem borer species belonging to 14 different genera in the families of Noctuidae, Crambidae, Pyralidae and Tortricidae were recorded from 34 wild host plants and through light trap. Among these families, Noctuidae was the highest in species richness in which 31 species were identified, out of which 15 species and two genera were new to science. This paper discusses the ecological interpretation of host plant–stem borer species interactions, particularly in relation to habitat disturbances.

Surveys were completed in Eritrea, Ethiopia, Kenya, Madagascar, Mozambique, Tanzania, Uganda and Zanzibar to assess the lepidopteran stem borer species diversity on wild host plants. A total of 24,674 larvae belonging to 135 species were collected from 75 species of wild host plants belonging to the Poaceae, Cyperaceae and Typhaceae. Amongst them were 44 noctuid species belonging to at least nine genera, 33 crambids, 15 pyralids, 16 Pyraloidea species not yet identified, 25 tortricids and three cossids. The noctuid larvae represented 73.6% of the total number of larvae collected, with 66.3, 3.5 and 3.8% found on Poaceae, Cyperaceae and Typhaceae, respectively. The Crambidae, Pyralidae, Tortricidae and Cossidae represented 19.8, 1.9, 2.5 and 0.1% of the total larvae collected, respectively, with 90.4% of the Crambidae and Pyralidae collected from Poaceae, and 99.7% of the Tortricidae collected from Cyperaceae. The lepidopteran stem borer species diversity in the wild host plants was far more diverse than previously reported.

Currently, the systematics of the African noctuid stem borers of the subtribe Sesamiina, which include major pests of cereals, is confused. In addition, their ecology is poorly known, as are the factors influencing their evolution. In this paper, we address these shortcomings for two genera of the Sesamiina, Sciomesa Tams & Bowden and Carelis Bowden. Mixed Bayesian phylogenetic analysis, which included their host plants and two mitochondrial genes, showed the genus Sciomesa to be polyphyletic. Two new genera were created, Pirateolea and Feraxinia. The genus Carelis proved to be paraphyletic and was subdivided into two sub-genera. The genera Sciomesa, Carelis and Pirateolea (named the 'Sciomesa genus group') share morphological traits, and the phylogenetic analysis showed that they had a common ancestor living on Cyperaceae and that they were distant from the genus Feraxinia belonging to another clade which had an ancestor living on Poaceae. Seven new species were described: Sciomesa gnosia sp. n., Sciomesia bua sp. n., Pirateolea nola gen. n, sp. n., Feraxinia serena gen. n., sp. n., Carelis australis sp. n., Carelis transversa sp. n. and Carelis agnae sp. n. Ten species were sunk as synonyms: Sciomesa mesoscia (Hampson) syn. n., Sciomesa mirifica Laporte syn. n., Sciomesa constantini Laporte syn. n. and Sciomesa etchecopari Laporte syn. n. are synonyms of Sciomesa mesophaea (Aurivillius); Acrapex sparsipucta Laporte syn. n. is a synonym of Sciomesa excelsa (Laporte) comb. n.; Acrapex congitae Laporte syn. n., Sesamia minuta Laporte syn. n. and Sesamia minuscula Laporte syn. n. are synonyms of Sciomesa boulardi (Laporte) comb. n.; Acrapex bryae Laporte syn. n. and Acrapex fayei Laporte syn. n. are synonyms of Feraxinia jemjemensis (Laporte) comb. n. Eleven new combinations were created: Sciomesa excelsa (Laporte) comb. n., Sciomesa boulardi (Laporte) comb. n., Sciomesa punctipennis (Krüger) comb. n., Pirateolea piscator (Fletcher) comb. n., Pirateolea argocyma (Fletcher) comb. n., Pirateolea cyclophora (Fletcher) comb. n., Pirateolea ochroneura (Fletcher) comb. n., Pirateolea funebris (Krüger) comb. n., Feraxinia nyei (Fletcher) comb. n., Feraxinia jemjemensis (Laporte) comb. n. and Carelis biluma (Nye) comb. n.
