 LESSON 16 



The Seasonal History of an Injurious Insect 

 Plant Pest 



Select one of the worst crop pests of your home locality. 

 Get bulletins* or books that will give its life history in full 

 detail, and study them. Study the diagram on page 102 

 (figure 41) of the Japanese beetle, and make a similar dia- 

 gram of your own, showing the same things for the pest you 

 have chosen. 



On the opposite page is an other example of the ex- 

 cellent way in which the U. S. Bureau of Entomology is 

 telling the story of the life history of a common pest, and 

 recommending control measures.
