1G0 EXPERIMENT STATION RECORD. 



A machine for dusting the plants with poison at the rate of 10 acres 

 per hour is noted, and instances cited to show the advantage of domes 

 tic fowls as destroyers of the weevil. Otherwise than this the remedies 

 noted are the same as have been given before. 



The San Jose and other scales in G-eorgia, H. N. Starnks 

 (Georgia 8ta. Bui. 36, pp. 31, figs. 21).— A popular account of the San 

 Jose scale and its habits, with special reference to Georgia, together 

 with brief mention of the following scales, more or less common in the 

 State : Florida red scale (Aspidiotus ficus), California red scale (Aonidia 

 aurantii), English walnut scale (Aspidiotus juglam-regite), gloomy scale 

 (A. tenebricosus), greedy scale (A. camellia}), new peach scale (Diaspis 

 lanatus), oyster-shell bark louse (Mytilaspis pomornm), long or Glover 

 scale (Jf. gloverii), purple scale (M. citricola), and the scurfy scale 

 ( Ch ionaspis furfu rus ). 



According to the map showing the distribution of the pernicious 

 scale, it has been found in 22 places in 17 counties, and 17 other places 

 are suspected, making 27 counties in all. 



A slight variation in the usual list of food plants for the insect is 

 noted for Berrien County, where it has been found on elm, rose, walnut, 

 black gum, corn, sugar cane, and certain weeds. 



The introduction of parasitic and predaceous enemies of the scale as 

 allies for its destruction is mentioned with favor. Sphcerostilbe cocco- 

 phila, the twice-stabbed ladybird (Chilocorus bivulnerus), and Pentilia 

 mi sella are noted as most effectual, especially the fungus. Both of the 

 ladybirds as adults attack preferably the older, while the larvae attack 

 the younger scales. 



Of the three classes of artificial remedies — total destruction, whale- 

 oil soap, and hydrocyanic acid gas — thought worthy of note, the first 

 is regarded as the best. The last is not thought a suitable remedy for 

 use by small growers or by any than experienced persons. Two appli- 

 cations of whale-oil soap (2 to 2£ lbs. to the gallon, warm) a month 

 apart, or about the middle of November and again about the middle of 

 December, followed in the spring by several applications of kerosene 

 and water (1 to 15) at intervals of two weeks, is recommended. 



Late winter or early spring use of the whale oil soap in the latitude 

 of Georgia is followed by disastrous results. The method is successful 

 only when the buds are thoroughly dormant, i. e., during December. 

 An emulsion of 8 oz. of ivory or whale oil soap, 1 gal. boiling water, 

 and 1 qt. kerosene used in the strength of 1:15, is recommended, but 

 the simpler remedy of kerosene and water in the proportion of 1: 15, 

 applied with the Weed Tank, is thought better. The use of pure ker-. 

 osene is mentioned, but is not at present recommended. 



The gas method is treated at some length with special reference to 

 conditions obtaining in Georgia. A tent weighing only 40 lbs. is 

 described, which can be made at a cost of from $0.50 to $7. The cost 

 of an outfit that can be kept in constant motiou by a gang of 4 men is
