Oligonychus ilicis, the southern red mite, is a species of mite found in the family Tetranychidae. It is a pest found throughout the world, targeting heather and holly.

Description

Eggs are found on the underside of leaves. Eggs in the summer are darker than eggs in the winter.[1]

Larvae are slightly larger than eggs and have six legs,[2] unlike the adults which have eight.[3]

Adults are around 0.5 millimeters (0.020 in) in length.[3] They are red or brown in coloration, darker than other species of spider mite.[1] Their bodies are ovular-shaped.[4]

The mites leave stippling or bronzing on leaves of plants.[1]

Life history

Oligonychus ilicis goes through several generations in a year.[3] The species targets broad-leaved evergreens, particularly of the families Ericaceae and Aquifoliaceae.[1]

There are two nymph stages with the succeeding stage darker and larger than the proceeding.[5]

Population densities are highest in autumn and spring.[1] In the summer, the mites undergo aestivation.[1]

Distribution

The species is known from Brazil, Italy, Japan, Korea, the Netherlands, Paraguay, and United States.[1]

Discovery

The species was described from a specimen found on an American holly in Batesburg, South Carolina.[6]
