INSECTS OF THE YEAR 1904 IN GEORGIA. 
By WILMON NEWELL and R. I. SmirH, Atianta, Ga. 
Continued experiments with the San Jose scale have demonstrated 
that a line-sulphur wash of 21 pounds of lime and 18 pounds of sul- 
phur in 50 gallons of water is fully as effectual as washes containing 
larger amounts of lime and sulphur, and also that the addition of 
salt to this wash is unnecessary, so far as the scale is concerned. By 
first mixing the sulphur with boiling water and then adding the 
unslaked me the boiling can be completed in from thirty to fifty- 
minutes in an iron kettle over a fire and in from twenty to thirty 
minutes where a full head of steam is available for boiling. Washes 
prepared in this way have given fully as good results as the stronger 
washes, boiled for a much longer time, which were formerly recom- 
mended. The lme-sulphur-caustic-soda wash has also given good 
results when properly prepared. For successful preparation of this 
wash we have found that it 1s necessary to first mix the sulphur with 
boiling-hot water and then to add slowly the caustic soda until all 
the sulphur is dissolved and a perfectly clear liquid obtained. By 
adding the stone hme to this clear liquid and allowing it to slake, a 
preparation is secured which is in no way distinguishable from the 
regular lime-sulphur wash. The effects of this wash upon the scale 
have not thus far been quite as satisfactory as these of the regular 
boiled wash. Experiments with caustic soda solution alone, which 
substance was highly indorsed by many agricultural papers during 
last winter, have demonstrated its utter worthlessness as a remedy for 
this pest. 7 
The Asiatic ladybird (Chilocorus similis Rossi), which in 1903 
gave promise of becoming abundant, has proved something of a dis- 
appointment. In the majority of the orchards where this species 
was colonized but few individuals could be found during the past 
season. In the case of an orchard at Marshallville, where ‘literally 
thousands of the beetles occurred in the summer and fall of 1903, no 
Specimens were found during 1904. Jn a near-by plum orchard, 
however, a few individuals survived the winter, and during early 
summer and midsummer they fed readily upon Pulvinaria amygq- 
dali Ckll., which species was fairly abundant in the orchard in ques- 
tion. Their beneficial work in keeping the latter species in check is 
much more marked than in the case of the San Jose scale, owing to 
the slower rate of breeding of the Pulvinaria. 
The plum curculio (Conotrachelus nenuphar Hbst.) has proven 
very injurious in the peach orchards in southern and middle Georgia, 
in some cases from 15 to 20 per cent of the crop being rendered un- 
marketable.
