 Dye-sensitized photooxidation reactions in the boll weevil, Anthonomus 

 grandis . Environ. Entomol. 4: 837-841. 



Adult boll weevils, Anthonomus grandis , fed for A days from emergence on a dye- 



impregnated artificial diet before illumination at 3800 /jW/cm fluorescent light 



-4 

 for 4 h yielded a dietary LDcq value of 9.9 x 10 moles/liter and a tissue LDc-j 



value of 2.4 x 10-7 moles/g wet weight for rose bengal. The dye-sensitized 



photooxidation reaction was treated mathematically and 2nd order rate constants 



4 / 

 of 4.50 liters/mole*min for dietary rose bengal and 2.25 x 10 g/mole'min for 



tissue rose bengal were calculated.

 of light-independent biochemical changes in the boll weevil, Anthonomus 

 grandis , caused by dietary rose bengal. Environ. Entomol. 6: 669-673. 



Diet containing rose bengal, when fed to newly-emerged adult boll weevils in the 

 absence of light, causes serious biochemical changes in the insect. Body weight, 

 total protein, and certain enzyme levels remain constant in the treated weevils 

 as opposed to increases seen in normaJ?" weevils. Total lipids decrease in treat- 

 ^ed" weevils relative to the constant values observed in controls. These data, 

 along with fluctuations in the amino acid pool sizes of treated weevils, suggest 

 that the changes are due to an energy stress in the insect, which can become 

 lethal, acting after the dye is absorbed into the tissues of the insect from 

 the gut.
