284 THE MONTHLY BULLETIN. 



most part onh^ one address will be given at one time, and at the most 

 not more than two, possibly three. 



Doctor "Webber has the assurance that the entire force of the River- 

 side Citrus station, both of Government and State experts, will be at 

 the service of the convention. Rich results of valuable research work 

 will be announced for the first time. Such able assistance from the 

 United States Department of Agriculture and the University Experi- 

 ment Station is greatly appreciated by all. Important papers will also 

 be read by members of the staff of the State Commission of Horticul- 

 ture. Several ladies who have made brilliant records in horticultural 

 lines have promised aid. Special sessions for ladies will be held each 

 afternoon, and women will be generously awarded places on the general 

 program and among evening speakers. Our leading growers, men who 

 have reached highest eminence, will give us their experiences and 

 methods. 



The first two days of the convention, Monday and Tuesday, will be 

 exclusively for the county horticultural commissioners, their deputies 

 and inspectors. Each forenoon will be devoted to experience recitals 

 and conferences, the afternoons to addresses from authorities and the 

 evenings to "round table" discussions. The convention proper will 

 hold from Wednesday, November 11th, to Saturday, November 14th, 

 inclusive. The first two days will be given to the consideration of 

 general topics that concern all fruit growers and horticulturists, while 

 there will be divided sessions the remainder of the time, the one devoted 

 to problems concerning citrus production and the other discussing 

 topics bearing on the growing of deciduous fruits. 



Will not all county horticultural commissioners, all fruit growers 

 and especially all our editors commence at once and continue to urge 

 attendance upon this convention. It will be a fitting prelude to the 

 great Panama-Pacific International Exposition of 1915. — A. J. Cook. 



A LIGHT TRAP FOR CATCHING CUTWORM MOTHS. 



Frequent attempts have been made in the past to control night- 

 flying moths, of which there are a numljer of destructive species, by 

 means of light traps. The various species of cutworm moths belonging 

 to the family Noctuidce, are preeminently night flyers and are readily 

 attracted to lights. 



The American Beet Sugar Company, which operates a factory at 

 Oxnard, Cal., and which has extensive plantings of beets in that section, 

 has been troubled to a considerable extent the past season with cutworms. 

 The idea of trapping the moths at night was conceived, with the result 

 that eight such light traps as the one shown in Fig. 82 were used with 

 quite phenomenal success, as far as catching great numbers of moths is 

 concerned, and that their efforts will result in great good can scarcely 

 be doubted. 



The trap shown in the picture is constructed of a shallow galvanized 

 iron pan about 4 feet in diameter, set on a platform a few feet above 

 the ground. Over the pan is hung a gas burner enclosed in globe and 

 connected with a tank within the frame, in which acetylene gas is 

 generated.
