No weevils developed in H. militaris , H. lasiocarpus , or okra ( H. esculentus ), 

 though adults were observed in the blooms of the first 2. In cages, they fed on 

 blooms of all the species.

 investigations. S. C. Agric. Expt. Sta. Ann. Rept. 48:100. 



A study was made of boll weevil breeding on Thurberia althea and hollyhock. 

 They were found to breed readily on Thurberia, and during 1935 3 larvae were 

 found in althea buds; 1 lived to be an adult weevil. They fed on the hollyhock but 

 did not deposit any eggs.

A. grandis, recorded in Venezuela for the first time on cotton in 1949, de- 

 velops continuously throughout the year. Observations in 1950, to discover other 

 food plants attacked, were made between February and July when cotton is not 

 available. C. affinis was found to be another host.

Adults of A. grandis fed and laid eggs on Cienfuegosia heterophylla . Adults 

 that fed on the buds and flowers survived for an average of 69 and a maximum of 

 134 days, and eggs were freely laid on the buds. 



1956 - Lukefahr, M. A new host of the boll weevil. J. Econ. Ent. 49(6):877-878. 



In July 1956, at Brownsville, Tex., the author noticed that several flower 

 buds of Thespesia populnea (L. ) Soland were turning yellow and falling off the 

 tree. Upon examination he found that they were infested with what appeared to be 

 boll weevil larvae. He also found four adult boll weevils on the foliage. All the 

 flower buds and seed pods eventually became infested. Several of the infested 

 buds were collected and 14 adult boll weevils emerged from them. All the adults 

 were normal in size, which indicated an adequate food supply. Nine of them were 

 placed in a cage containing potted cotton plants, and in a short time all the fruit- 

 ing forms showed evidence of feeding or egg punctures. 



Thespesia populnea belongs to the family Malvaceae and is commonly called 

 portia trees or locally is referred to as a tulip tree. 



1959 - Walker, J. K. , Jr. Some observations on the development of the boll weevil on the 

 wine cup, Callirrhoe involucrata (Nutt.) A. Gray. J. Econ. Ent. 52(4):755-756. 



In the United States, 2 plants other than the cotton plant have been observed 

 to serve as hosts for the boll weevil. These are Hibiscus syriacus L. and 

 Thespesia populnea (L.) Soland, and both plants are members of the family 

 Malvaceae. In Central Texas a very common malvaceous plant, the wine cup, 

 Callirrhoe involucrata (Nutt.) A. Gray, blooms and matures during April and May. 

 Eggs of the boll weevil were implanted into 4 wine cup buds. No adult weevils 

 emerged from these buds although a later examination indicated that larval feed- 

 ing had occurred in one bud. 



In April 1957, boll weevils were removed from hibernation cages and trans- 

 ferred to small screen cages in the laboratory where they were provided with 

 buds of the wine cup for food and oviposition. After a period of 2 weeks, examina- 

 tions of the buds revealed the presence of boll weevil eggs. The insects also 

 oviposited within the maturing fruit called capsules. In several instances, eggs 

 were found deposited on the outside surface of the buds and capsules. 



Boll weevil eggs were removed from cotton squares and implanted individ- 

 ually in wine cup buds. Each bud was partially enclosed with a thin layer of 

 paraffin to prevent premature opening. Out of 40 buds in which eggs were im- 

 planted, 7 adult weevils emerged. Examination of other previously implanted buds 

 indicated that a large percentage of the eggs hatched and the larvae lived for
