SOME GEORGIA INSECTS DURING 1906.

The year jnst closing: has not been notable for any particular out- 

 break of insects, though certain crops have sufi'ered more than com- 

 monly from the attack of conunon species. By that I mean that the 

 weather conditions were favorable to the development of many field 

 croj) insects, such as the cotton boilworm, harlequin cabbage bug, 

 army worm, corn weevil, and others. The record of insects of the 

 year attacking sta})le crops is, however, much less interesting than 

 that of last year. 



COTTON INSECTS. 



The boilworm {Heliothis ohsoleta Fab.) was reported from Mitch- 

 ell. Houston, Coffee. Lowndes, Baldwin, and Madison counties. Our 

 correspondent from Valdosta, Lowndes County, reported his cotton 

 damaged to an extent of nearly 00 per cent. It may be of interest in 

 connection with boilworm injury to state that the feeding holes of 

 the worms were in many instances the forerunners of anthracnose. 

 a disease which caused the loss of thousands of bales of cotton in 

 Georgia this 3^ear. Except for being an aid to the entrance of the 

 anthracnose disease we do not believe that the boilworm caused its 

 usual amount of damage. 



The cotton leaf-worm {Alahama argiUaeea Hiibn.), strange to say, 

 was not once reported during the j'ear. This meant that it did very 

 little, if any, actual damage, but not that it did not appear. We are 

 not so fortunate as to have become entirely rid of this insect. 



The cotton aphis {Aphis (joHsypii Glov.) was present as usual on 

 the young cotton. 



Liipcrodes hy^nnnens Cr., reported from Georgia last year at the 

 meeting at New Orleans as the new cotton beetle, appeared again this 

 season, but not in such great numbers. This insect was discovered at 

 Lyons, Tatnall County, in a 10-acre field, and at "Woodstock, Chero- 

 kee County, both reports coming in on July 9. 



Chalcodermus ccneiis Boh., the cowpea-pod weevil, was first re- 

 ported from Statesboro, Bulloch County, (m May 5, its earliest 

 reported occurrence in Georgia. Our correspondent stated that young 

 cotton was l)eing destroyed by this insect as fast as the plants ap- 

 peared above ground. Specimens from INIetter, Bulloch County, Avere 

 reported as ruining young cotton in a few days. Specimens were also 

 received from Emanuel, Randolph, Berrien, and Clay counties. In 

 nearly all instances the weevil Avas present in cotton fields following a 

 crop of cowpeas. Rotation would undoubtedly prevent most of the 

 damage caused by this insect, so far as cotton is concerned.
