 the spectral composition of the light used to extend the photoperiod. 



J. Econ. Entomol. 60: 1565-1567. 

 Regions of the near-ultraviolet and visible spectrum effective for inducing 

 diapause suppression in the boll weevil, Anthonomus grandis Boheman, were 

 investigated. One group of weevils was exposed to 11 hours of fluorescent 

 light-time and 13 hours of dark-time that initiated diapause (L11:D13); 

 the 2nd group was exposed to 13 hours of fluorescent light-time and 11 hours 

 of dark-time that inhibited diapause (L13:D11). A 3rd group was exposed to 

 11 hours of fluorescent light-time followed by 2 hours of illumination with 

 narrow wavebands of light of different spectral compositions and 11 hours 

 of dark-time (L11+2:D11). The spectral region most effective for suppressing 

 diapause was found to be between 400-655 nm. The 359-390 nm and 670-1000 nm 

 spectral regions were less effective.

 A study of the impact of an eradication program on nontarget species is an 

 important and necessary part of any pilot experiment which may lead to large 

 programs. The Environmental Protection Agency requires an environmental impact 

 statement before it wil? approve programs such c- an attempt to eradicate the 

 boll weevil throughout the Cotton Belt. Furthermore, the side effects from 

 an eradication program must be figured into the assessment of costs and ex- 

 pected benefits of the program. Thus, the side effects of the Pilot Boll 

 Weevil Eradication Experiment (PBWEE) on certain nontarget organisms were
