802 AGRICULTURAL APPROPRIATION BILL, 1924. 



The insect attacks some 150 different sorts of trees and plants, 

 including a gootl many of economic importance, as the Japanese per- 

 simmon, the pecan, rubber plants, roses, peach, plum, and the like. 

 We do not know, along with its further spread, whether it will become 

 an important pest in the Georgia peach belt or not. The insect is 

 too new to enanle us to surmise what it may do. 



We have a laboratory in New Orleans where the insect is being given 

 careful conj-idcration. as a study of its parasites, its methods, and rate 

 of spread. Experiments are being made in the New Orleans territory 

 and also in the citrus area in Alabama with sprays and other methods 

 of control. 



We can report distinct progress in our knowledge of the insect it«elf 

 and progress in developing control measures. 



Mr. BuriLVNAN. What does it attack if 



Doctor QuAiNTANCE. It attacks many kinds of plants 



Mr. BuciiANAX (interposing). No, no; does it attack the limbs or 

 the fruit ^ 



Doctor Quaixtancp:. It attacks the twigs and leaves and fruit 

 of certain fruit-b(>aring plants at least. It is especially noticeable in 

 camphor trees. It attacKs the small branches, which die very quickly. 

 It first was discovered by reason of injury to these trees in New Or- 

 leans. Our men working in Japan are going to send us some par»isites 

 from Japan if possible. They have one or two now under cultivation. 



Mr. Anderson. Are there any developments under this item worthy 

 of note at this time? 



FOR ADMINISTRATIVE AND MISCELLANEOUS EXPENSES. 



Doctor Howard. I think not. The next is general administrative 

 expenses — no increase. 



FOR PREVENTING SPREAD OF MOTHS. 



Then comes page 211, preventing spread of moths. 

 Mr. Anderson. There seems to be a slight reduction. 

 Doctor ITow^vRi). It is reduced from S600,000 to S531,000. 

 Mr. Anderson. I think you better tell us something about the 

 status of this moth proposition. 



r.vrsY AND HKO\VN-TAiL moths. 



Mr. Burgess. The gvpsy moth and brown-tail moth activities 

 have been carried on along the same lines as during the previous 

 year, with the exception that some foreign work has been attempted 

 to bring in parasites to work on these species. As you know, the 

 work is divi(l('d into tliree sectitMis. One section handles the scouting 

 and border work to determiiu' the area that is infested and to carry 

 on clean-up work along the border territory. Practically all of that 

 work is done in New England, with the exception of the work that is 

 done in New Jersey, wliere the niotli was found a little over two 

 years ago. 



Tiie New England work along (he border was held up for a time 

 last spring because our funds were very low until the appropriation 

 j)assed, and then the force was increased as rapidly as possible, but 

 mjury resulted l)efore that work coidd be resuuHMJ.
