Fig. 4. Showing the benefits to be obtained by spraying. The plant on the left was 

 sprayed with a suspension of an alcoholic extract of tuba root and then infested 

 with 22 larvae which were all poisoned. The other plant was not sprayed and was 

 infested with 10 larvae which destroyed it in a week. 



PLATE X. 



Fig. 5. A sack exposed for three weeks in a tomato house infested by H. oleracea, showing 

 the trapped pupae. 



Fig. 6. Showing a baited trap in a tomato house, communicating only with the outside. 

 In three months only one H. oleracea was caught in it. In the same period over 3000 

 were captured in similar traps in a block of 12 infested tomato houses.
