Mass rearing of Chilo spp. on artificial diets and its use in resistance screening uri icon

abstract

  • Several species of Chilo are serious pests of cereal crops. The important speciesattacking cereals are Chilo agamemnon, C. orichalcociliellus and C. parrrllus on malze andsorghum; C. auricilius and C. zacconius on sugar-cane, and rice; C. suppressalis on rice; andC. sacchariphagus indicus on sugar-cane. Insects are reared In the laboratory on natural andartificial diets for various purposes, namely for insecticide testing, hormone and pheromonemanipulation, biological control, host-plant resistance, etc. Rearing of an insect In thelaboratory requires rearing facilities, colony establishment, research and development ofrearing techhiques, resources, and maintenance of insect quality. All these aspects for rearingmajor Chilo spp. have been discussed. However, detailed information is available only for C.partellusand C.supprersalis. Techniques used for resistance screening anddamageevaluationagainst spotted stem borer, C. partellus using naturally occurring populatlon and artificialinfestation are described
