Two species of tomato worm, the southern tomato worm and its 

 relative, the northern tomato worm, feed extensively on tomato 

 plants or in a lesser degree on eggplant foliage throughout their 

 respective areas. They are large greenish or brownish cater- 

 pillars having at the rear end of the body a somewhat curved, 

 sharp horn. Feeding by these caterpillars is most extensive on 

 the tomato, where they work in the dense foliage, often detected 

 only by excreted material covering the ground beneath the plant. 



The adult, an ashy gray moth, deposits single eggs on the under 

 side of the leaves. From these the young caterpillars hatch and 

 in about a month mature and enter the ground to pupate. There 

 may be several generations each year, depending largely on sea- 

 sonal conditions or the degree of latitude. 



Control : Hand picking or spraying.
