 mellltor attacking larvae of the boll weevil inside a cotton square. 

 Ann. Entciol. Soc. Am. 67: 520-521. . . ' 



The oviposition of Bracon mellltor on larvae of the boll weevil has been ob- 

 served in open petri dishes. A new technique made possible for observation 

 in detail the natural act of oviposition of these parasites on boll weevil 

 larva inside a cotton square (flower bud) under a binocular microscope.

of boll weevil parasitism (Col.: Curculionidae) . Entomophaga 21: 123-125. 

 The cotton plant has a profound effect on the behavior and ability of parasites 

 to successfully attack the boll weevil, Anthonomus grand i s Boheman. The most 

 important native parasite of the boll weevil, Bracon mellltor Say, prefers to 

 oviposition Frego bract cotton rather than normal bract cotton. An imported 

 parasite, Heterolaccus grandis Burks prefers ovipositions on normal bract 

 cotton rather than Frego.

 of Bracon mellltor , a parasite of the boll weevil. J. Ga. Entomol. Soc. 

 10: 183-186. 



Bracon mellltor Say, the most important parasite of the boll weevil, Anthonomus 

 grand i s Boheman , "^a s found to emerge very early in the season. Therefore, an 

 alternate host is required if the parasite is to survive until squares infested 

 with boll weevils are available for parasitization.
