MAY IMPORT <. INSECT ENEMY
 TO KILL MOTH

Introduction of insects from Eur ope-parasite enemies-may be nee essary to aid in combating the satin moth, a newly discovered foreign pest among the poplar and willow trees over a large area around Boston, Mass, Two of. it's enemies, insects already introduced into this country sy moth, are found to be doing valiant service against the new pest, and the prospect of controlling it by parasites is encouraging, say entomologlsts of the United States Department of Az ricu1ture. It may be necessary, how ever, to bring in from Europe some of it's enemies that do not exist here at the present
 In Department Circular 167, The Satin Moth: Ar Introduced Enemy of Popiars and Willows, the depart ment gives a review of government and State work against the pest since it's discovery in this country July l, 1920, and describes the habits and life of the insect in it's various stages. Time has not permitted experiments to find the most effective remedies. The larvae were so nearly full-grown at the time they were first found that spraying did not prove effectual. From their present knowledge of the insect. entomologistS advised the fol- lowing treatment for the season of 1921:
  as they are in full leaf with arsenate of lead at the rate of 10 pounds to 100 gallons of water, using soft soap <or a tsticker-" If the infestation is severe, it may be necessary to re- peat the operation in June. If egg clusters are abundant on the trees in
 July, spray again with the same ma terial about August l.
 If these suggestions are followed and the amount of spraying is gov
 erned by the density of infestation. satisfa ctory results should be secured it is said.
 To predict the ultimate importance of a newly introduced insect is rather hazardous, say the entomOlogists. IT the feeding is confined to the pop lars and willows the damage will be trees are not considered of prime economic importance, there are cer- tain areas where they grow sausfac-
 torily that will not not support pc ,ann moFe re l the osier or basket willow, which in
 some sections is of considerable eco homie importance Another. season, l 1t is thought, will doubtless give the
 necessary opportunity to determine l the destructive possibilities of the in-
 sect.
 l Although the original source of the | infestation can not be determined, it
 was brought into this country during
 the dormant season in crev1ceS or 1 bark on live or dead trees. It is | likely that the insect has been in this
 country several years and has only | become abundant enough to spread very rapidly during the last two or | three years. It is now known to oc- | cur over an area of GAP square miles, l including 60 townships in Massachu- | setts and 4 in New Hampshire. 1 Pickpockets in Chicago are pro- 1 tected by a highly organized trust, who hire three criminal lawyers by l the year to protect them, according 1 to charges made by the chief of de- | tectives. He states stringent laws l in the East are driving the crooks to | Chicago, and that it is almost inpos- | sible to secure conviction of a pick l pocket because of the testimony of | their lawyers and their "witnesses'' | and their ability to obtain bonds at | once and escape being identified by their victims.
