Book Description
Excerpt from Citrus Fruit Insects It has been estimated that the average cost of fumigation per tree, taking the whole of the citrus belt, amounts to about 30 or 40 cents, which means an expense of approximately $30 to $40 per acre, and this is done on an average about every other year. This is intensive insect fighting, but when the improved market value of the fruit is considered, it is money judiciously spent with such a valuable crop as the orange or lemon.

Book Description
Excerpt from Citrus Fruit Insects in Mediterranean Countries In Spain, during July, 1913, the Mediterranean fruit-fly was found in peaches and oranges, but in very limited numbers. The extent of infestation in peaches, its favorite food, amounted to only a fraction of 1 per cent. It is true that most of the peaches had not yet matured, and there is no doubt that a heavier infestation occurred later in the season. Many of the pears, apples, and other fruits were examined.

Book Description
Excerpt from Insects Injurious to Citrus Fruits and Methods for Combating Them The Object of this bulletin is to describe the life history Of some Of the various insects injurious to citrus trees, and also to give the various insecticides which are being used and their effect on both trees and insects. For years the planters Of Florida have been spraying their trees with various emulsions to keep their fruit clean and trees healthy. The time has arrived for planters in Porto Rico to pay more atten tion to the appearance of their fruit if they desire to realize top market prices. In order to grow clean fruit more spraying at the proper time is necessary. The experiment stations Of the United States have shown that beneficial results may be Obtained by spray ing. Orchards that produced practically nothing but worthless fruit have been sprayed, with the result that 90 to 95 per cent of their fruit 18 perfect.

Book Description
Excerpt from Biology and Control of Citrus Insects and Mites Earlier bulletins published by the University of California on citrus insects have been out of print for several-years, and the aim of the present publication is to replace in part those earlier bulletins, for which there has been a constant demand, as well as to bring the subject Of citrus-insect control in California up to date. Since many of the requests call for detailed information on the biology of the pests, and because such information is least available, it seems desirable to cover that phase of the subject as adequately, as the limited space in this publica tion will allow. The order of discussion of the pests is more or less in accordance with their classification as they occur in the animal kingdom, and not necessarily in accordance with their relative importance as pests of citrus.

Book Description
Excerpt from Red Spiders and Mites of Citrus Trees Next to the scale insects, red spiders and mites are the most important pests of citrus trees in California. On account of their small size, and because the foliage and fruit of the tree are not conspicuously marred either by their presence or by the covering of sooty mold fungus, as is the case with some of the scale insects, the actual injury done by red spiders and mites is not always appreciated. _their distribution is very general over the citrus sections, and they may be found in some numbers at most any season of the year. So long as they do not become numer ous the injury they do is, not important and in such cases it is not good economy to apply treatment. Because of their more orless continual presence in scattering numbers some growers take red spiders as a mat ter of course, and fail to recognize their importance when they become abundant and do damage, or come to a realization of their injurious nature after most of the damage has been done and the spiders them selves begin to disappear, as they often do. While, therefore, the presence of spiders in scattering numbers should be the cause Of no par ticular concern, the presence of. Excessive numbers of spiders should be the cause of enough concern for the grower to start immediately to apply control measures. Dropping of the leaves and fruit is the ultimate result of red spider injury. But the cause should be checked long before this extreme effect is evident.

Book Description
Excerpt from The Citrus Insects of Tropical Asia All species of citrus are attacked, though the heaviest infestations are found upon lemon and pummelo. As many as 84 adults have been reared from a single lemon. NO thoroughly satisfactory means of control has as yet been devel Oped for this species. The eggs are resistant to kerosene emulsion, and the larvae are inaccessible to contact sprays during their entire period of development except for the short time in which they wander about in search for a place in which to pupate. Kerosene emulsion will kill a considerable number of these larvae and of the pupae, but. It must be applied frequently because of the overlapping Of the generations.
