WHITE FLY IN CALIFORNIA Bulletin of the Agricultural Experiment Station, University of California. [BY C. W. WOODWORTH.] The white fly has at last become established in California. The most destructive insect in the citrus groves of Florida is this species of white fly, the Aleurodes citri. It is considered by the growers there as much more injurious than any of the scale insects attacking these fruits. Our trees were supposed to be free from the pest, but now a well established colony has made its appearance at Marysville at a center of travel by both steam and electric railways where the conditions seem particularly favorable to its spread over the state. The seriousness of these facts to the citrus industry of this state renders it imperative that full publicity be given them in order that the proper steps may be taken to meet this emergency. We are not sure that the insect is confined to this one locality. Every one who has trees should carefully inspect them and submit all suspicious specimens to some one capable of accurately identifying them. The experiment station will be glad to examine and report on any that may be submitted for this purpose. It may be entirely possible to eradicate an insect before it has become well established, but it will if allowed to increase, become too widely distributed to effectively handle. Many have been very apprehensive of the danger of introducing this insect them and submit all suspicious specimens to some one capable of accurately identifying them. The experiment station will be glad to examine and report on any that may be submitted for this purpose. It may be entirely possible to eradicate an insect before it has become well established, but it will if allowed to increase, become too widely distributed to effectively handle. Many have been very apprehensive of the danger of introducing this insect from Florida, and have been instrumental in having most stringent laws enacted preventing the importation of anything from that state liable to be infested, while others have maintained that the insect could not live in this climate at all. In support of this idea it has been claimed that the insect must have been introduced into the state many times on nursery stock before these laws went into effect and since that time on plants that escaped the attention of the inspectors. Many other species of white flies are liable to live in California, however, including at least one injurious species. We do not have to speculate any longer on this matter since the insect in question is now not only existing here but thriving. Moreover, the insect is not appearing in the most humid parts of the state, but in the interior where the black scale is unable to thrive, that is, in a climate comparable to Riverside. Though we now know that the white fly does live and thrive in our climate in the city of Marysville, there are those who still believe that our orchards are not menaced, still arguing on the basis of the climatic differences between California and Florida. The red scale, the black scale, and the purple scale are all Florida insects and have not found our climate in possible. Possibly the white fly may prove to be different, but it does not seem the part of wisdom to permit the white fly to have free access to our citrus orchards on the chance that it may not thrive there. LIFE HISTORY! The white fly must have been in California at least a full year judging by its distribution and abundance at Marysville, but no observations have been made on its life history and habits except during the last few weeks since its discovery in the state. There is but little doubt, however, that it will prove much the same as in Flor- LIFE HISTORY! The white fly must have been in California at least a full year judging by its distribution and abundance at Marysville, but no observations have been made on its life history and habits except during the last few weeks since its discovery in the state. There is but little doubt, however, that it will prove much the same as in Florida. The most elaborate study of this insect is that reported in Bulletin 67 of the Florida experiment station by Professor H. A. Gossard. In the following account of the insect much will be taken from this publication. The Egg—At the present time the insect is chiefly in the egg stage. These are shown very much enlarged in figure 2 in Circular 30, which was photographed from a specimen collected at Marysville, and illustrates how numerous they become. There were many thousands of such eggs on this leaf. Nearly every leaf on the trees in that part of town was similarly infested. These eggs are so small as to be scarcely visible to the eye singly, but the badly infested leaves appeared as if covered with mould. While rather less than half the town of Marysville is badly infested, still a careful examination would show the presence of a few eggs on nearly every tree in town. The eggs of the white flies are all very much alike and can be at once distinguished from every other known group of insects. The shape of the egg and of the stalk at the end by which it is attached to the leaf are sufficient to distinguish them. It is not, however, easy to distinguish between the eggs of the different species of white flies. Presence of an egg of this character on the leaf of an orange or lemon tree is quite conclusive evidence of the destructive of Florida. According to Gossard, quires from three to two hatch, according to the weather. The Nymph—The young hatching very much resembles scale insect, but can be distinguished by comparing mounted specimen under high power microscope.

Other reference to this importject will be given in our next Walnut Huller Mr Wm. Jackson of Orange, who is agency for this county of walnut huller, was in town last interviewing growers and extr the merits of his machine. Machine consists of spring steel rushes, set on an angle and upon a solid wooden drum, concave cross-bars with half penings which allow the hulls to sooth wheel can be raised and lowered with a simple handscrew, to give nuts that are hard to hull more tension. and when nuts are very small it requires the drum to be a little closer to the bars, but it is best not to give nuts any more pressure than is necessary to hull them. These machines are made in different sizes, with or without self-feed, but would recommend the self-feed, as it gives the best satisfaction. One man can hull a ton and a half a day without the self-feed. Two men can hull three tons per day with self-feed and a six-inch machine. The bars are kept sharp with a file by taking out handscrews, turning the block down and out of the way. The side of the machine is open to allow the drum to come out, by putting on a handle or pully and turning in the direc-tion to make wires close in, which reduces the diameter of the tooth wheel. Care should be taken to keep the deflecting plate in touch with the wheel so as not to allow any nuts to pass between the wheel and the deflecting plate. The machines are strongly built and nicely painted, and shipping Fashion Invite the public portations. Pat weight is 100 pounds.
