Citrus fruit pests in California occur in more or less well defined areas. Some species are most destructive under the cooler temperatures near the ocean. Other species are destructive only where the Summer weather is hot and dry. There are intermediate types. The distribution of these pests in 1927 is compared with that of 1907. An attempt has been made to designate the maximum temperatures and the minimum humidities which appear to limit the destructiveness of the more important citrus pests.
