all people and technique problems are solved beltwide. 2) The best possible 

 insecti:ide application, be it by air or ground. Mississippi is doing yeoman 

 extension work with aerial applicators. Such work should be done beltwide and 

 would have an immediate impact. In both of these areas the producer pays for the 

 service. As long as he is satisfied with a sloppy job, this is what he can expect 

 to get. Research on cotton insects is active and productive. Producers rapidly 

 adopt improved practices as soon as they are proven.

 Rev. Entomol. 22: 139-155. . 



The paper gives origins, history, and current status of extension entomology 

 in relation to agriculture, homemaking, and many recent demands and problems. 

 The future of extension entomology is explored and its role as one phase of 

 the entomological profession is evaluated.

 years experience with point-sample cotton insect scouting. Arkansas 

 Agric. Exp. btn. Bull. 754, 40 pp. 



The Point Sample Method of scouting has been used in Arkansas by cotton insect 

 scouts since 1962. This bulletin evaluates experiences with this method from 

 1962 through 1967. A total of 21 locations were included to represent the 

 cotton-grQwing areas of Arkansas. Squaring rates by week of squaring were 

 more variable than had been anticipated from the original research on which 

 the Point Sample Method was based. Thus, scouting should begin when most 

 plants have one countable square (diameter of 1/4 inch or greater without the 

 bracts). The range appears to be 11,000 to 60,000 squares per acre during 

 the first week of squaring. After that recommendations should be based on 

 week of squaring and whether the number of squares per acre is rising, remain- 

 ing at the same level, or dropping. In a typical field squaring will accelerate
