Abstract: Eotetranychus hicoriae (McGregor), pecan leaf scorch mite, overwinter as females in the rough bark area on limbs of pecan trees. Data for the 1979 year showed that overwintering mortality exceeded 70%. In the spring, overwintering females began to oviposit within 7 days after initiation of feeding. In laboratory rearings, eggs did not hatch at 18.3°C, and at 35°C 97% of the individuals died as immatures. It is suggested that these temperatures may limit population growth in the field. In the laboratory, higher mortality with increasing temperatures may be due to increasing mortality of individuals that would develop into males.
