104 ASSOCIATION OF ECONOMIC ENTOMOLOGISTS. 



Saperda Candida Fab. and Chrysobothris femorata Fab. have 

 caused some damage to apple orchards, but on account of the small 

 number of apple orchards in the State these borers are not given 

 sufficient attention. 



The codling moth (Carpocapsa pomonella) has been the basis of 

 some experimental work by the board of entomology in Georgia 

 this past season. Our life history study, carried on by W. V. Eeed, 

 has shown quite conclusively that we have only two broods of this 

 insect in Georgia. Our spraying experiment failed for lack of suffi- 

 cient infestation in the orchard selected for the experiment. 



Aphis mali Fab. causes great damage to young apple orchards and 

 also in the nursery rows. Kerosene emulsion as it is commonly pre- 

 jjared has not been found to be a reliable remedy. Tobacco decoction 

 has given better results. 



Hoplia trivialis Har. destroyed opening buds of Japan plum at 

 Adairsville. Specimens were received April 12 with a report that 

 the beetles were preventing the better portion of a good-sized tree 

 from putting out foliage. The buds were eaten out close down to 

 the base. 



The woolly aphis (Schizoneura lanigera Hausm.) still continues to 

 be one of our worst apple pests. As I reported last year, we have 

 successfully killed the root form by application of kerosene emulsion. 

 It may be of interest to state here in advance of a bulletin which we 

 hope soon to publish that 10 and 15 per cent kerosene emulsion have 

 been used without injury on roots of apple trees from 2 to 10 years 

 of age. We injured 2 trees by an application of 40 per cent emulsion, 

 but have not observed any injury from lesser strengths, not even from 

 30 per cent, which was tested. We would, however, consider it unsafe 

 to use over 20 per cent emulsion and 10 or 15 per cent seems to be 

 amply sufficient. The aerial form of woolly aphis is best controlled 

 by tobacco decoction. 



GARDEN INSECTS. 



Without giving a list of all the insects injurious to garden crops 

 I wish to say that these pests have been rather more than commonly 

 abundant, their increase being due, perhaps, to weather conditions. 

 Harlequin cabbage bugs, cabbage worms, cutworms, aphides, squash 

 bugs, etc., were very much in evidence during the past summer. 



SHADE AND FOREST TREE INSECTS. 



Hyphantria cunea Dru., the fall webworm, appeared in great num- 

 bers during August and September in a considerable portion of 

 Georgia. In Columbia County I observed nests on September 4 on 

 persimmon bushes that had been entirely stripped of foliage. In
