Inventory and distribution of groundnut insect pests in Burkina Faso
1993
Traore, S.
Insect collection was performed in on-station and on-farm trials in Burkina Faso. The research stations included Saria and Gampela in central Burkina Faso, Kouare in the East and Niangoloko in the West. On the varieties observed at ground level, termites (Microtermes spp) and millipedes (Pterodontopyge rubesceus and Pterodontopyge spinosissima) were the most important. At the pod level, termites and millipedes made scarifications and perforations. Larvae and adult beetles of the Tenebrionidae family and white worms of the Scarabaeidaea family, were found in the soil near severed roots. Termites and millipedes were more important in the Saria, Gampela and Kouare research stations where the rainfall is less than 800 mm, but their incidence was not significant at Niangoloko (031 mm). On leaves, stems, and flowers the following insect pests were found: 1. Groundnut aphid (Aphis craccivora), 2. Green leafhopper (Emposa dolichi), 3. Cicadulina spp. C. imbila, C. triangula, C. arachidis, and C. similis, 4. Flower thrips (Megalurothrips sjostedti), Spodoptera littoralis (Lepidoptere noctuidae), Heliothis armigera and Maruca testulalis and meloides of the Mylabris species. Main sedentary groundnut locusts were Oedaleus senegalensis, Chrotogonus senegalensis, Hieroglyphus daganeusis, and Pyrgomorgha cognata. During the inventory, ladybug beetles and syrphids were observed among Aphis craccivora colonies. In Burkina Faso, termites and millipedes populations were important in areas with less than 800 mm of rainfall and Aphis craccivora and Empoasca dolichi in areas above 900 mm
