Effects of spider mite infestations on dent corn in California. Journal of Economic Entomology, 55: 823-825.

Abstract
Three species of spider mites commonly occur on dent corn in central California. The two-spotted spider mite (Tetranychus telarius (L.)) is the predominant species but the Pacific spider mite (Tetranychus pacificus McGregor), the Banks grass mite (Oligonychus pratensis (Bank)) are frequently present. Heavy mite infestations in 1961 caused u premature drying of the foliage, increased stalk breakage, a lower moisture content of grain at harvest, and kernel shrinkage, all of which resulted in significant reductions in the yield of grain. An association of mite infestations with the incidence of stalk rot was observed. Control of mites on dent corn with ethion resulted in an increase of 2,559 pounds of grain per acre or a yield increase of 47.2% over untreated corn.
