of pellets. With the present rearing and sterilizing methods, the new 

 equipmant provided a saving of ca. 18 man hr of labor per day for making the 

 adult (let pellets needed for each 1 million sterile male weevils produced per 

 week and the labor saved would be greater if both sexes of weevils were fed 

 the pellets containing the chemosterilant.

 boll weevil eggs on artificial diet. J. Econ. Entomol. 68: 433-434. 



Granular materials were used to cover the artificial diet and the eggs of 

 Anthononus grand is Boheman after the eggs were sprayed on the diet surface 

 as a substitute for the usual diet scarifying and drying operation. The 

 number of adult weevils produced from the petri dishes when the diet and 

 eggs were covered with mortar sand, vermiculite, fine mineral granules, and 

 corcob grit was as great as or greater than that produced from the regular 

 egg implanting method. By use of the granular material covering, the scarifying 

 and drying operations of the regular egg planting method can be eliminated.

 weevil eggs from diet pellets. Trans. ASAE 20: 454-456. 



The equipment designed, constructed and tested and the operational techniques 

 used in evaluating the equipment and systems were satisfactory for harvesting 

 boll weevils eggs for food pellets commonly used for laboratory reared weevils. 

 ThJ equipment and system provides for harvesting large volumes of weevil eggs 

 with low man hours of labor without reducing the hatch of eggs.

 weevils. U.S. Sci. Educ. Adm. Adv. Agrlc. Technol. Soutn. Ser. (ISSN 

 0193-3728), No. 10, 6 pp. 



The cabinet holds trays of rearing medium during the emergence period. Newly 

 emerged boll weevils are attracted by light into attached collecting cages.
