Insecticide resistance in field populations of the legume pod-borer, Maruca vitrata Fabricius (Lepidoptera : Pyralidae), on cowpea, Vigna unguiculata (L.), Walp in Nigeria
International Journal of Pest Management 45 (1), 57-59
Abstract: The legume pod-borer, Maruca vitrata Fabricius, from two locations (Shika and Samaru) was found to be resistant to cypermethrin, dimethoate, and endosulfan. When compared with a susceptible reference strain, resistance ratios ranged from 17- to 53-fold for cypermethrin, 27- to 92-fold for dimethoate, and 15- to 37-fold for endosulfan. Low level of tolerance to lambda-cyhalothrin (3- 4-fold) was observed in Samaru. Non-chemical approaches or the use of chemical insecticides only when necessary is recommended to prevent or delay the development of resistance to insecticides.
