The LongTilus Scale. 



The longulus scale attacking the orange is similar to the soft brown 

 scale, but is more grey in color, less shiny, and the young appear to 

 be more flattened to the leaf and are more transparent. This scale 

 is causing much damage to citrus fruits in certain parts of the State. 

 This scale has been little affected by fumigation with hydrocyanic 

 acid gas at the time the best results are obtained in black scale fumiga- 

 tion. Mr. Delacourt Kell, county horticultural inspector of the 

 Pomona and Claremont district, has found tliat the best time to fumi- 

 gate for this scale is from July 20th to the end of August, using a 

 three-fourths i?chedule. At this period the scales are in the riglit 

 stage for killing by fumigation. It must be remembered not to fumi- 

 gate at a temperature of 70 degrees Fahr. or above. 



MISCELLANEOUS INSECTS. 



Grasshoppers. 



The appearance of the grasshopper is too well known to warrant a 

 description. C4rowcrs whose orchards are surrounded by w^aste lands 

 should, if possible, burn the waste areas over when the .young hoppers 

 are plentiful. This should l)e done at night, for the reason that the 

 insects are practically inactive at that time. The use of the hopper 

 dozer will destroy myriads of the grasslu)ppers in grain and hay 

 fields. For a description of this machine the reader is referred to 

 page 15 of Nos. 1 and 2, Volume II, of the IMonthly Bulletin of the 

 California State Commission of Horticulture, by E. 0. Essig. The 

 following by Mr. Weldon is worthy of note : 



The Pellucid Grasshopper. 



(.Camnula pellucida Scudd.) 



On May 18th the writer made a trip with County Horticultural Com- 

 missioner Vaile of Ventura County to investigate grasshopper injury 

 to beans and beets on property of the American Beet Sugar Company, 

 near Oxnard. The hoppers, which were identified by Mr. E. 0. Essig as 

 the above species, were found to be migrating from hilly pasture lands 

 where the feed was getting scarce into large fields of the aforementioned 

 crops. IMany of the hoppers were winged, and during the heat of the 

 day would rise a few feet from the ground and fly very rapidly toward 

 the cultivated fields. Had it not been for promptness on the part of 

 the beet sugar company in applying a remedy great devastation would 

 no doubt have resulted. The remedy applied was a bran Paris green 

 mixture after a formula, slightly modified, recommended by the Kansas 

 Department of Entomology. Such excellent success was attained in 

 the work of destroying this pest that the formula exactly as they used 

 it follows: 



Bran 50 pounds 



Paris green 3 pounds 



Lemons 10 fruits 



Syrup 3 quarts 



Water 5 gallons
