The rice borer in Madagascar (M. separatella). Effectiveness of insecticides. Varietal susceptibility. Experiments of 1961


, : The rice borer in Madagascar (M. separatella). Effectiveness of insecticides. Varietal susceptibility. Experiments of 1961. Agron. trop, Paris, 18: 4, 427-459

Further experiments on the control of Maliarpha separatella Rag. on rice in the Marovoay region of Madagascar were carried out in 1961, and different varieties of rice were tested for their susceptibility to this Pyralid. The following is based largely on the authors' summary of the work. Between 24th April and 20th June, a period of heavy infestation, nine applications of each of ten sprays were made on small plots.
