August 23, two in-field traps were installed in field 43 and baited with grand- 

 lure. On August 24, one ebony male and one ebony female were collected in the 

 traps. On August 28, eight egg-punctured squares were collected from the field. 

 These squares yielded 7 larvae (3 first, 3 second, and 1 third instar) and one 

 good egg. In-field traps on the same date contained one ebony male, one ebony 

 female, one native male and three native females. The same traps contained two 

 ebony males and two ebony females on August 29. During the first 3 weeks in 

 September, 64 ebony, 150 bronze and 6 native weevils were captured in 2 traps. 

 On September 19, 25 weevils were collected by shagging 100 ft. of row. There were 

 6 ebony, 17 bronze, and 2 native weevils in this collection. Another shagging 

 collection of 74 weevils had 64 ebony and 10 bronze weevils. From August 24 

 until January 23, a total of 1,295 weevils were collected from this field. Ten 

 native weevils were captured on January 23. This field is unique since it was 

 the only field in zone I found to develop a general field infestation during 

 August. On December 10-13, 1973, woods-trash samples were collected from zones 

 I, II, and III, and an outside sample was also collected along the Natchez Trace 

 for comparison. Each sample consisted of 2 yd of suitable woods trash taken 

 from areas adjacent to cottonf ields. Varying numbers of samples were taken 

 from each field. These records show an average of 48.4 weevils per acre in 

 woods trash in zone I compared with 1,452 per acre in zone II, 15,488 per acre 

 in zone III, and 7,018 per acre outside the area.
