Abstract

In a study covering 3 years, experiments were carried out in order to determine the feasibility of producing a microsporidian pathogen Nosema marucae in the spotted stalkborer Chilo partellus. A maximum yield of 4.9 times 108 spores/larva (equivalent to 3.1 times 1010 spores/g fresh larval body weight) was obtained in 3rd instar larvae. It is considered that the production is inexpensive and can be readily adapted for small scale pathogen propagation systems in the tropics. 1993 The Netherlands Entomological Society
