These differences were attributed to differences in quality and quantity of 



gametes produced by the two sexes. \

 noids: CXXVIII. Synthesis of 7-methyl-3-methylene-6-octen-l-ol (y-

Treatment of 7-methyl-3-oxo-6-octen-l-ol (II) with dihydropyran and HCl affords 

 the pyranyl ether (III) which on Wittig reaction with methylenetriphenylphos- 

 phorane yields 7-raethyl-3-methylene-l-(tetrahydro-2'-pyranyloxy)-6-octene (IV). 

 IV on treatment with PTS furnishes the title compound.

 Entomol. Soc. Am. 67: 82S-827. 



When the boll weevil, Anthonomus grandis Boheman, was artificially inseminated 

 by a new technique, fertile eggs were obtained from 68.7% of the females; how- 

 ever, the number that laid fertile eggs dropped quickly over a 2-week period. 

 Not as many spermatozoa reached the spermathecae of artificially inseminated 

 females, and the spermatozoa were apparently not as active as those of normally 

 inseminated females- The presence of active spermatozoa in the copulatory 

 pouch stimulated egg production and normal oviposition behavior. The behavior 

 of females artificially inseminated with only male accessory gland material 

 was indistinguishable from that of virgin females.

 Anthonomus grandis . J. Insect Physiol. 21: 1275-1278. 



In female boll weevils, Anthonomus grandis , spermathecal filling was not affect- 

 ed by severing the spermathecal muscles. Females whose spermathecal muscles 

 were severed 2 to 4 weeks after mating laid infertile eggs and resumed virginal 

 ovipositlonal behavior indicating the importance of this muscle in supplying 

 sperm for egg fertilization. The presence of normal active sperm within the
