in zones III, IV, V, and the northeast corner of II. By May 2, 40 sites were 

 established one or more miles from cottonfields and 32, adjacent to 1972 or 

 1972-73 cottonfields. During May, 27 additional noncottonfield-oriented sites 

 were located in or near zones I and II. Through August 1, these 99 sites each 

 included 10 traps (placed 20 to 35 ft apart in a row) which were checked for 

 weevils and rebaited with grandlure weekly. It is concluded that at least 

 most of the adult boll weevils captured by noncottonfield-oriented traps in 

 zone I during June, and again in August, were migrants from outside the area. 

 This is supported by the negative captures before both of these periods, and 

 by the gradient of decreasing captures toward the center of zone I during the 

 periods. Of more interest, however, is the fact that 28 noncottonf ield sites 

 in zones I and II captured no weevils during the last week in July, while in 

 the same period, 11 of 38 noncottonfield-oriented sites in zones III, IV, and 

 V captured weevils.

Of 42 species of arthropods that parasitize the boll weevil, Anthonomus 

 grandis Boheraan (Coleoptera: Curculionidcie) , 33 are Hymenoptera, 6 are 

 ^'TJlptera, 1 is Coleoptera, and 2 are Acarina. Notes on other h»sts, dis-

 weevil populations. Coop. Econ. Insect Rep. 18: 430. 



In studies at the Boll Weevil Research Laboratory, traps baited with live 

 male boll weevils ( Anthonomus grandis ) are being developed as a method of 

 survey for survival of overwintered boll weevil populations. Traps of two 

 types were superior to several others. A Stikerrf&-coated wing trap is
