ROSE BUGS N THE GARDEN

] HordticulturaI commission said yes terday that the insect which had beer ! doing damage in the alfalfa fields ! was d species of thrip.
 From his various observations ! and experiments he eblieves it to be 1 the same that did considerable dam age to the peach, pear, plum and ap- | rlcot trees of the valley this year damaging the crop 10 considerable extent and in some cases killing the | trees.
 Its way of working is to begin l early. It ingratiates itself into the just opening leaf and blossom buds. feeding upon them. particularly upon the pistils of the flowers. and in this way to d large extent denudes the tree of both it's foliage and fruit. leaving it open to the scalding action of the sun. This results always In, damaging and in sometimes killing the tree, 10 large extent destroying the crop and retarding growth
 Naturally, the damage was not no ticcd until it was well under way. when it required some examination to determine what it might be and some experimentation in a country where the conditions are largely new and where the treatment required is likely to be equally SD. and so practically nothing could be done this year to save the crop or prevent the ravages of the insects to any appreciable de- gree.
 But the examination which the en- tomologist immediately undertook showed that the insect cause was not a new one but one with which or1- chardists in other parts of the United States are quite familiar, and his cx- periments showed that it could be controlled very fairly by a nicotine solution, not however. easy to make and handle, and being thus warned of what they haves to contend with or chardists of this valley and Arizona generally may be able to control il Very fairly in the future by strict and early attention at leafing and bloom Ing time. \ fact the blessing O-N which orchardists and farmers will appreciate is that such visitations as those of this year. on both alfalfa and
 
 creased numbers of the insect. which Is always with us.
 The process of preparing and using this nicotine solution will appear in the forthcoming annual report of the entomologist and horticultural com mission, which will be issued soon.
 The commission is also in receipt recently of a letter from Mir. James L. Finley. of Camille, Santa Cruz county, accompanied by generous number of specimens of a bug which he says is doing much damage to or chards and gardens in that vicinity. appearing often in we'll defined and considerable swarms. and fairly eat Ing people out of house and home. The application of Paris green and Coal oil sprays proved ineffective. and he requests to know what else can be done
 pr. Morrill, says the bug,-which is fully three eights of an inch long about half as wide with hard outer wings and of a dull yellowish color on top-is variety of the well known rose beetle. which breeds well in grass sod on sandy soil
 The principal element in the hest remedy for these insects is arsenate. of lead. IL has been found. however Tn this case as in those relating to many other things. that the remedy can be applied better in a sweet me dunn than in sour one So the ar senate of lead is mixed with almost any kind of easily flowing sirup and water. in form as follows: 10 pounds arsenate of lead. l gallon sirup, and 100 gallons water. these proportions to be maintained for different quan- titles in to total.
 There will be full discussion of both these matters in the forthcom- ing annual report of the entomol- ogist, issued by the commission, cop ics of which should be applied for now by those who desire them. The nicotine remedy will be there stated in detail and how to apply it. Those desiring copies can address the Ari- zona Horticultural Commission at Phoenix, and their applications will be listed to be filled as soon as the book is issued.
