 Pest, Platynota tinctana (Walk.) in California. — MtJihj. Bidl. 

 Cal. State Dept. Agric, Sacramento, ix, no. 8, August 1920, pp. 

 341-343. 



Platynota tinctana is recorded as injuring oranges in southern 

 California. This moth has been found in company with Tortrix 

 citrana (orange tortrix), but is less injurious. The various stages 

 are described. The larva is usually found webbed within old dry 

 leaves or fallen flower petals close to the fruit. The damage to the 

 fruit is caused by puncturing the rind. P. tinctana is generally kept 

 in check by parasites, of which at least three distinct species of 

 Hymenoptera have been reared.

 Mthly. Bull. Cal. State Dept. Agric, Sacramento, ix, no. 8, August 

 1920, pp. 344-349. 



The loss caused by the bean Bruchids, Bruchus ohtectus. Say, and 

 B. quadrimaculatus, F., for 1918 is estimated at about £824,000. 

 Details are given of the bionomics of these beetles as observed in 

 California. 



Successful results were obtained by fumigation with carbon bisul- 

 phide for 48 hours at the rate of 6 lb. to 900 cubic feet. A mite, 

 probably Pediculoides ventricosus, Newp., effectively checked 

 B. quadrimaculatus under laboratory conditions, but owing to the 

 discomfort it causes to man, its use is not advocated.
