304 INSECT PESTS OF FARM, GARDEN AND ORCHARD 



Tomato Worms 



The large green horn- worms which attack the foliage of the 

 tomato are the same as those previously described which attack 

 tobacco (see page 228). Usually, they are not so numerous but 

 that they may be readily controlled by handpicking, but if neces- 

 sary the same remedial measures may used as advised for them on 

 tobacco. 



The Tomato Fruitworm 



The worms which commonly bore into the green and ripening 

 tomatoes are the same as the tobacco budworm and the cotton 

 bollworm (see pages 234 and 254), under which names their habits 

 and life histories have been fully described. 



Obviously tomatoes should not be planted on land which has 

 been in corn or cotton infested by this insect the previous year, 

 unless it has been given thorough winter plowing and harrowing. 



It has seemed to the writer that trap rows of sweet corn might 

 be used for protecting tomatoes as they are used with cotton, but 

 no experiments seem to have been conducted which show the prac- 

 ticability of the method. As the young caterpillars feed a little on 

 the foliage before boring into the fruit, a thorough spraying with 

 arsenate of lead, 3 pounds to 50 gallons, will undoubtedly protect 

 the tomatoes if applied as soon as the eggs are laid, and with one 

 or two later applications at intervals of ten days, the exact time 

 depending upon the latitude and season, as indicated by the life 

 history (see page 181).
