Abstract

The work on insects in relation to the spread of orange tree quick decline has heen going on since 1945. During this period it was determined which insects are found commonly in southern California citrus groves and over 750 transmission tests were conducted in an attempt to discover the vector.

Also in this issue:

Agricultural outlook: As of December, 1948

Color retention: Pigmentation in processed fruits and vegetables is complex problem

Wind machines in orchards: Best adapted to combatting short, light radiation frosts

Live-virus PE vaccine limitations: Dangers, advantages of new product against pneumoencephalitis

Growth of olive fruit: Follows three-period growth pattern of other stone fruits

Developments in mechanized farming equipment: Cotton harvester further improved toward full efficiency

Developments in mechanized farming equipment: Brush-type almond harvester and new prune catcher successful in field

Processed apricots: Frozen, dehydrated and canned products studied for effects on skin textures

Radioactive sugars: Synthesized for studies in the metabolism of plants and animals
