Maize Stalk Borer (Nkongwa)
FACTSHEETS FOR FARMERS Created in Rwanda, May 2012 www.plantwise.org Maize Stalk Borer (Nkongwa) Recognize the problem Damage of leaves and stem (holes) by maize stalk borer. (Photo by Maize stalk borer also known as Nkongwa in Kinyarwanda is an insect which Anne Bruntse) attacks maize. It makes holes on the leaves and moves into the stem. You can often see lumps of chewed plant material (frass) left by the insect. The leaves turn yellow and the plant dries. The plant might not grow to full size. Sometimes young leaves which are damaged by stalk borer can be pulled off easily. If the stem is split open, the stalk borer can be seen inside. Background The stalk borer is an insect which attacks maize and sorghum. The adult (a moth) lays eggs on the leaves and the hatched caterpillars then enter the stem. The caterpillar which is cream in colour with a dark brown band around the body causes most of the damage. Damaged grains can be easily attacked by other diseases. The crop is more susceptible when grown by itself and on poor soil. Stalk borer caterpillars inside maize Management stem. Notice brown chewed plant • Crop rotation: Plant maize one season, a legume the next season and material. (Photo by Anne Bruntse) a tuber crop after that. This will stop the spread of the insect. Using the legume also improves the nitrogen of the soil, which is good for the plant. • Improve soil fertility: Increase nitrogen level in the soil by applying farm yard manure or green manure at the base of the plant.

Dunber: Armyworm Insect Injury to Corn Following
Journal of Economic Entomology, 109(4), 2016, 1691–1697 doi: 10.1093/jee/tow101 Advance Access Publication Date: 20 June 2016 Field and Forage Crops Research article Increased Risk of Insect Injury to Corn Following Rye Cover Crop Mike W. Dunbar,1 Matthew E. O’Neal, and Aaron J. Gassmann Department of Entomology, Iowa State University, Ames, IA 50011 ([email protected]; [email protected]; [email protected]), and 1Corresponding author, e-mail: [email protected] Received 16 February 2016; Accepted 19 April 2016 Abstract Decreased pest pressure is sometimes associated with more diverse agroecosystems, including the addition of a rye cover crop (Secale cereale L.). However, not all pests respond similarly to greater vegetational diversity. Polyphagous pests, such as true armyworm (Mythimna unipuncta Haworth), black cutworm (Agrotis ipsilon Hufnagel), and common stalk borer (Papaipema nebris Guenee), whose host range includes rye have the poten- tial to cause injury to crops following a rye cover crop. The objectives of this study were to compare the abun- dance of early-season insect pests and injury to corn (Zea mays L.) from fields with and without a rye cover crop on commercial farms. Fields were sampled weekly to quantify adult and larval pests and feeding injury to corn plants from mid-April until corn reached V8 stage, during 2014 and 2015. Measurements within fields were collected along transects that extended perpendicularly from field edges into the interior of cornfields. Adult true armyworm and adult black cutworm were captured around all cornfields, but most lepidopteran larvae cap- tured within cornfields were true armyworm and common stalk borer.

Received: 13 May 2014; in revised form: 5 June 2014 / Accepted: 20 June 2014 / Published: 8 July 2014 Abstract: Busseola fusca (Lepidoptera: Noctuidae) is an important pest of maize and sorghum in sub-Saharan Africa. One century after its first description by Fuller in 1901, inaccurate information based on earlier reports are still propagated on its distribution (e.g., absent from the lower altitudes in East Africa) and host plant range (e.g., feeding on a large range of wild grass species). This review provides updated information on the biology, distribution and genetics of B. fusca with emphasis on insect-plant interactions.
