 as Tumigants for control of adult boll weevils: laboratory studies. J. 

 Econ. Entomol. 65: 1650-1651. . 



Adults (2-4 days old) of a laboratory-reared strain. Ebony Pearl, Anthonomus 

 grandis Eoheman were readily controlled with methyl bromide (MeBr) or 

 aluminum phosphide. At temperatures below 10°C, much higher concentration- 

 time produces (CT) of MeBr were apparently required for control than expected 

 if the relationship between CT and temperature were a straight line. There 

 was some indication that adults 9-11 days old were more tolerant to alumi- 

 num phosphide than 2- to 4-day-old adults. Fumigation schedules are recom- 

 mended for quarantine control.

In-season control of the boll weevil is an essential element in any program of 

 boll weevil control and elimination. To be successful, it will have to be per- 

 formed in a thorough manner, with every producer and every field included. We 

 already have the knowledge and methodology to suppress the weevil to an extremely 

 low population level in preparation for a diapause program. Because a united 

 effort is so important, leadership of the cotton industry must produce incen- 

 tives which will assure the effective participation of every cotton producer in 

 the Cotton Belt. Lack of cooperation on the part of any single producer will 

 be critical in the ultimate success of the program.
