707. . 1977. Longevity and fecundity of female boll weevils placed with 

 varying numbers of males. Ann. Entomol. Soc. Am. 70: 673-674. 



The bursa copulatrix of female boll weevils, An thonomus grandis Boheman, 

 distended greatly and occupied nearly the entire abdomen due to repeated 

 insemination when held with 20 to 40 ^ was ca. 1/4, or less than when 1 9 

 was held with 1 <^. Fecundity of a female held with 10 or more males was 

 significantly less than that of a female held with 1 c5.

 and attractiveness of laboratory vs. overwintered males. J. Ga. 



■ Entomol. Soc. 12: 321-327. 

 Untreated males of Anthonomus grandis Boheman produced significantly 

 greater numbers of sperm than males treated with different sterilizing 

 procedures. Males given 0.09% busulfan (1,4-butanediol dimethanesulfonate) 

 in adult diet produced 4.11 million sperm during their lifetime. Males 

 treated with an acute dose of 8000 rad alone or in combination with O.OIZ 

 dif lubenzuron, (N-[ [4-chlorophenyl)amino]carbonyl]-2, 6-dif lurobenzamide) , 

 produced ca. 1/2 as many sperm as males treated with busulfan. Males fed 

 0.09% busulfan + 0.35% hempa (hexamethylphosphoric tramide) in the adult 

 'diet produced ca. 1/4 as many sperm as males treated with busuifan alone. 

 Laboratory males produced ca. 2.4 times more sperm than overwintered males. 

 Laboratory males were 2.5 times more attractive than overwintered males.

 male boll weevils in the laboratory. J. Econ. Entomol. 69: 454-461. 



Male Anthonomus grandis Boheman, treated with a combination of Y-irradiation 

 and hempa in the diet mated ca. one-half as often as untreated males when 

 paired individually with 4 virgin females/day. Examination of spermathecae 

 showed that females mated to treated males contained an average of ca. 1/3
