Autor: R. S. Woglum, J. R. Lafollette
Publikováno v: Journal of Economic Entomology. 21:678-682
A unit method of orchard inspection for the citrus black scale ( Saissetia oleae Bern.) is described. The unit is the small number of well developed scale on a branch 6 to 10 inches long. In determining the comparative value of spray materials only t

Climatic Influence on Citrus Insect Distribution in California
Autor: R. S Woglum
Publikováno v: Journal of Economic Entomology. 21:708-715
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 intermedi

Observations on the Life History and Morphology of Agulla Astuta (Banks) (Neuroptera: Raphidiodea: Raphidiidae)
Autor: E. A. McGregor, R. S. Woglum
Publikováno v: Annals of the Entomological Society of America. 52:489-502
This raphidian predator, common some years in Southern California foothill citrus orchards, normally completes its life cycle in a single year. Larvae first appear in May, are active through the summer, and enter winter dormancy in October. A prepupa

The History of Hydrocyanic Acid Gas Fumigation as an Index to Progress in Economic Entomology
Autor: R. S. Woglum
Publikováno v: Journal of Economic Entomology. 16:518-521
Hydrocyanic acid gas fumigation was discovered in 1886. From 1886–1893 it underwent decided improvement as a fumigant for citrus trees; 1893–1900, greenhouse, nursery stock, stored products and mill fumigation were introduced; 1907–08, orchard

Observations on Insects Developing Immunity to Insecticides
Autor: R. S. Woglum
Publikováno v: Journal of Economic Entomology. 18:593-597
The development of increased immunity to hydrocyanic acid gas by the red scale and black scale in certain districts of Califomia, which have in the past relied upon fumigation for control, has become sO pronounced that a single treatment even at a gr
