Life fecundity tables were studied forSpodoptera litura (Fabricius) when reared on castor (Ricinus communis L.), groundnut (Arachis hypogea), okra (Abelmoschus esculentus L.) and sunflower (Helianthus annuus L.) under laboratory conditions at 26·8±2°C temperature. The net reproductive rate (R0), was calculated in each case.
The tobacco caterpillar,Spodoptera litura (Fabricius) was reared on different host plants under laboratory conditions. This article reports the growth and development ofS. litura on different host plants.
