essential equipment. The status of sterilization technology lias increased 

 greatly since the South Mississippi Trial Experiment but still constitutes 

 the weakest link in the chain of technology required for successful boll 

 weevil eradication. It is hoped that results from 1977 field trials and 

 experiments will change this picture. Competitiveness of the sterilized 

 weevils in the field as well as the overall efficacy of the sterile male 

 technique with boll weevil still are not fully understood. This needs to 

 be resolved before large area eradication is attempted. The North Carolina 

 trial should proceed, but with the restriction that the program is not ex- 

 panded beyond the second year until proper evaluation of its success and/or 

 failure. If success is achieved, expansion should be geared directly to 

 rearing and sterilization capability and effectiveness, as determined by re- 

 search and by the availability of resources to provide for ample rearing, 

 sterilization, and evaluation needs of the expanding program.

studies. Ann. Entomol. Soc. Am. 62: 315-318. 

 The attraction, feeding, and ovipositlon of Anthonomus grandis Boheman on the 

 dioecious plant Hampea sp., was compared with Deltapine Smoothleaf cotton by 

 laboratory bloassay. Plant parts and extracts of the male plant were comparable 

 to cotton in attractiveness and stimulation of feeding, but extracts of female f 



buds and capsules were significantly less attractive than extracts of male buds 

 and cotton buds. A volatile repellent (s) in the extracts of the female buds and 

 capsules probably masked the attractive material (s) present, but after storage
