Simyra henrici, an orange and "brown spiny caterpillar, is common in corn- 

 fields throughout the state. It eats the leaves of corn, but has been more of a 

 curiosity than a serious pest. 



Bagworms are now evident in evergreens. In some instances it is too late 

 to control them; but if the worms are still small, use carbaryl, lead arsenate, mala- 

 thion or toxaphene sprays. 



Caution : Before applying insecticides, read the labels carefully and fol- 

 low all precautions. This will not only insure personal safety, but will also elimi- 

 nate insecticide residue hazards.
