For the future control of the pest it is suggested that it might be 

 advantageous to cut permanent trenches transversely across each 

 upland pasture in a similar manner to the Canadian trencher for 

 catching the armv worm [Cirphis vnipunda]. If both sides of the 

 trench were trimmed so as to be quite vertical, the caterpillars might 

 be trapped from two directions. After a severe winter such as that of 

 1916-17. due warning might be sent to the farmers of any expected 

 infestation and trenches could then be cut directly the frost disappeared. 

 Poison sprays proved ineffectual, as the bent grass will not retain any 

 considerable quantities of the spray. Poisoned bran mash such as 

 is scattered broadcast in Canada is hardly feasible in the case of the 

 antler moth, but a mixture of "20 lb. bran and 1 lb. Paris green stirred 

 into 3^ gals, water contiiining 3 finely chopped oranges or lemons and 

 2 quarts of molasses might be scattered over a belt about 10 yards 

 wide between an mfested area and a crop it is desired to protect. It 

 is hoped that the order regarding exposed lights may be somewhat 

 modified in future by the authorities during the burning season. 

 Greater discrimination should be shown in the preservation of bird 

 life ; rooks and starlings are a great help in control, while the scarcity 

 of the lapwing encouraged the infestation in the year imder discussion.

The control of the cotton boll wee^'il [Anthojwmus gr<7ndis] in 

 Georgia is an entirely different problem from that faced by other 

 States which have made a thorough study of it, 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 trans- 

 mission 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 m carrying the 

 disease from one field to another and from one plant to another when 

 these are not in contact. 



The work of controUing the usual pests of peaches and apples has 

 been continued and elaborated. Other insect pests included the cotton 

 or melon aphis [Aphis gossypii] and the cabba<ie aphis [Aphis bmssim-e], 

 which were controlled by a dilute solution of Blackleaf 40. Nczara viri- 

 dula (green soldier bug) became a serious pest owing to the lack of 

 parasites due to the tmfavourable season. Only strong contact poisons, 

 such as 10 per cent, kerosene emulsion, give any degree of success. 

 Clean cultivation and the destruction of rubbish in and about the 

 fields in winter is advocated. The barnacle scale, while not a serious 

 pest, is numerous on greenhouse and ornamental plants. If parasites 

 do not sufficiently control it, a weak kerosene emulsion should be sprayed 

 on the plants just after the young have attached themselves. 

 Aspidiotus obscura (gloomy scale) injures many shade trees ; a spray 

 composed of one part scalecide to 7 or 8 parts water is recommended. 



Insects attacking stored products include the granary weevil 

 [Calandra granaria], rice weevil [C. oryzae], saw-tooth grain beetle 

 [Silvanus surinameims] and red or square-necked grain beetle
