Four species of Lepidopterous pests of tobacco in the field are 

 dealt with in this paper, viz. : — Prodenia litura, F., Heliothis {Chloridea) 

 -assulta, Gn., Phytomctra (Plusia) eriosoma, Gn., and Phthorimaea 

 (GnorimoscJienia) heliopa, Lower. 



Of these, the Noctuid, Prodenia litura (tobacco cutworm), for 

 many years recorded as P. littoralis and incorrectly identified in 

 America as P. ornithogalli, Gn., occurs throughout the oriental 

 and southern palaearctic regions and in the Philippines. Eggs are 

 laid on both surfaces of the leaf, and the larvae begin eating along the 

 midribs and proceed gradually to the margins, till none of the leaf 

 blade remains. They have also been recorded as feeding on castor-oil 

 plants, peanuts, lettuce and celery. Since the larvae pupate in the 

 ground, tobacco should not be planted the year following an infested 

 crop. The food-plants of this pest in the Philippines are : — tomato, 

 tobacco, calaboa {Monochoria hastatu), maize, cabbage, rice, sweet 

 potato, castor {Ricinus communis) and jimson-weed {Datura sp.). In 

 India its recorded food-plants are : — lucerne {Medicago sativa), jute 

 {Corcfiorus s-pp.), indigo, potato, mulberry {Morusa.lba), Ficusinjectoria, 

 Elensine coracana, ground nut {Arachis hypogaea), Phaseolus radiatus, 

 Cajanus indicus and sugar-cane {Saccharum ojficinaruni). 



Heliothis assulta (tobacco false bud-worm) occurs during the 

 entire gro^vth period of the crop in the Philippines. The eggs are
