Ballal, C. R., S. P. Singh., Sunil Joshi and N.S.Rao (1998). Multicellular tray for rearing the larvae of Helicoverpa armigera (Hübner) (Lepidoptera : Noctuidae). Entomon 23(4) : 307-312 (1998).

A multicellular larval rearing unit has been devised for rearing Helicoverpa armigera (Hübner). The tray is made of transparent acrylic and is amenable to surface sterilisation. It is reusable, durable and hence economical. Rearing in this tray provided 80 to 90% recovery of H. armigera pupae. Larval escape was nil and disease incidence by contamination was minimum. Cannibalism was totally avoided. Pupal formation could be recorded easily and pupal collection was also easy.
