California insects: Survey provides accurate data for study of state's insect problems
by Paul D. Hurd
pp3, doi#10.3733/ca.v008n05p3
Abstract
Abstract not Available – first paragraph follows: Insects of economic importance in California–whether native or introduced–have often been studied with almost complete disregard for their relationship to other insect species, largely because of the immediacy of a specific problem.

Alfalfa and water table levels: Studies on effect of alfalfa on water table indicate need for close control of irrigation
by James N. Luthin , William Bianchi
pp4-5, doi#10.3733/ca.v008n05p4
Abstract
Abstract not Available – first paragraph follows: Alfalfa extracts soil-moisture uniformly to the depth of its root system, and rapidly growing alfalfa will lower the water table appreciably.

Leafy seviiiano olive cuttings: Rooting readily obtained under mist humidification produced satisfactory trees in experiment at Davis
by H. T. Hartmann
pp6-16, doi#10.3733/ca.v008n05p6
Abstract
Abstract not Available – first paragraph follows: Most varieties of olives can be propagated readily by either leafy softwood cuttings or by hardwood cuttings. However, the Sevillano–one of the leading commercial olive varieties in California–has been difficult to propagate by cuttings; so nurserymen have resorted to grafting on seedlings as a means of propagation.

by E. F. Serr
pp7, doi#10.3733/ca.v008n05p7

by A. E. Michelbacher , C. S. Davis
pp8, doi#10.3733/ca.v008n05p8
Abstract
Abstract not Available – first paragraph follows: A strain of walnut aphid–Chroma-phis juglandicola (Kltb.)–encountered in the San Jose area during insect investigations in 1953 exhibited definite resistance to parathion.

by Stephen Wilhelm , Richard H. Sciaroni
pp9-10, doi#10.3733/ca.v008n05p9
Abstract
Abstract not Available – first paragraph follows: Verticillium disease of chrysanthemum can be controlled by fumigation.

Abstract
Abstract not Available – first paragraph follows: No correlation between moisture content of corn and field losses was evidenced in Antelope Valley field trials– under the conditions of the study–with mechanical harvesters in 1953.

pp12-15, doi#10.3733/ca.v008n05p12
Abstract
Abstract not Available – first paragraph follows: The fluorine investigations referred to in the following progress report were initiated by the late I. C. Kaudy and continued by the authors.

by Robert L. Rudd , Richard E. Genelly
pp13, doi#10.3733/ca.v008n05p13
Abstract
Abstract not Available – first paragraph follows: Pheasants showed aversion to lindane-treated grain in acceptance tests at Davis.

Earth materials: Growth trials show no benefit to chicks on practical starting ration
by F. H. Kratzer , C. R. Grau
pp14, doi#10.3733/ca.v008n05p14
Abstract
Abstract not Available – first paragraph follows: Results of growth trials with young chicks indicate no justification for the use of natural earth materials in rations for those chicks fed a practical starting ration.

Infectious bronchitis: Vaccines released for growing birds not yet tested for laying hens
by R. A. Bonkowski , D. E. Stover
pp14-15, doi#10.3733/ca.v008n05p14a
Abstract
Abstract not Available – first paragraph follows: Infectious bronchitis is widely distributed in the major poultry raising areas in California. However, all respiratory diseases of poultry are not caused by infectious bronchitis virus. Vaccination with a live virus vaccine against an impending respiratory disease should not be attempted until the respiratory condition for which the vaccine is intended has been correctly diagnosed by a qualified veterinarian or laboratory.
