long, cylindrical case, with a long tongue-case bent backward 

 from one end until its top touches the case, forming a handle like 

 that of a pitcher. These chrysalids are often turned up by the 

 plow or spade. 



Remedies. As the worms are so large and conspicuous, hand- 

 picking is a comparatively easy and a certainly effective remedy. 

 Kerosene emulsion (see page 9) may be effectively used in spray- 

 ing. 



The worms are infested by the larvae or maggots of a small 

 hymenopterous parasite that deposits its eggs on the worm. The 

 maggots, on hatching, burrow into the body, living on the juices 

 of the host, and finally coming out on the back of the worm, 

 where they spin small, white, silken cocoons. These cocoons are 

 conspicuous on the infested Tomato Worm. 



Kansas Notes. This pest rarely does serious damage, but is 

 continually present over the State.
