saprophagous flies were forced out of infested seed cotton, cottonseed, and green 

 cotton bolls with little difficulty. A heater using a Nichrome wire grid which gave 

 uniform heat was devised for large Berlese funnels, thus allowing large amounts 

 of insect-infested material to be processed with high larval yield. 



PLANT DISEASES

 Ga. State Bd. Ent. B. 48, 36 p. Atlanta. 



The control of the cotton boll weevil in Georgia is an entirely different prob- 

 lem from that faced by other states, because soil and climatic conditions are 

 different. During 1916 the increase of the pest was rapid, although a systematic 

 fight has been made in all counties where it occurred. A study of the possible 

 insect transmission of cotton diseases led to the conclusion that while insects 

 probably play but a small part in the dissemination of cotton anthracnose in a 

 field, they may play a large part in carrying the disease from one field to another 

 and from one plant to another when these are not in contact. 



1934 - Taubenhaus, J„ J., and L. D„ Christenson. Insects as possible distributing agents 

 of cotton wilt caused by Fusarium vasinfectum . (Abs.) Phytopathology 24(7):839- 

 840. 



In experiments in the United States, insects that had fed in screened cages 

 on various parts of cotton plants infected with wilt ( Fusarium vasinfectum ) were 

 surface- sterilized, together with some of their faecal pellets, and cultured on 

 nutrient agar in petri dishes. Good growth of the fungus was recovered from the 

 larvae of Anthonomus grandis Boh. When, however, insects fed on infested cotton 

 were starved for several days until all the faecal matter had been eliminated, no 

 fungus was obtained from sections of the alimentary canal. As the fungus re- 

 covered in these experiments was capable of infecting normal cotton plants, many 

 insects that feed on cotton may aid the spread of the disease.
