At the present time some 24 States are in this cooperative arrangement, sending in 

 weekly records of light-trap collections of the more important insect pests. Since rec- 

 ords are collected throughout the year, particularly from traps located in the more 

 Southern States, it is possible to follow species succession and occurrence. Often the 

 presence of many species of insect pests may not be evident at a given time, yet with the 

 use of light traps, emergence dates are closely determinable. 



Continued improvement in light-trap design and construction, and lamp selectivity, 

 which can be utilized for attracting insects in general or for specific species, will 

 contribute greatly in the field of insect detection. 



While some progress has been made in determining the distance of insect response 

 to lamps, more detailed studies are necessary to meet the demands of both entomologists 

 and farmers alike. 



It is desirable to have a more efficient and practical portable light trap for use in 

 detection work. The writer has received inquiries from many places in the world, such 

 as the Belgian Congo, Australia, Iran, South America, and Mexico, as well as from our 

 own country for such a type trap. 



Light traps are an essential part of our entomological investigations, and the field 

 for their continued use would appear unlimited.
