Phenology was studied between 1992 and 1994 at different elevations (between 80 and 820 m above sea level) and on 2 different host species (apple, Malus silvestris Miller, and pear, Pyrus communis L.). The association between accumulation of degree-days (DD) and rate of oviposition and egg hatch was analyzed with simple linear regression using 10°C as the lower developmental threshold temperature and 15 February as the starting date. Temperature-driven rates of oviposition and egg hatch were similar for the 3 yr, all elevations, and the 2 tree species. Elevation, host species, and year did not meaningfully affect the amount of thermal units required by P. oleae to initiate oviposition and egg hatch. Oviposition and egg hatch is expected to begin at 40.1 and 184.8 DD, respectively. The model accurately predicted the onset of egg hatch during 2 yr consecutively in 1 tested plot (deviations between observed and expected dates of <3 d). © 1996 Entomological Society of America Pest Management and Sampling nationallicence Parlatoria oleae nationallicence Malus silvestris nationallicence forecasting model nationallicence oviposition nationallicence egg hatch nationallicence degree-days nationallicence Pinhassi Nil Department of Entomology, Institute of Plant Protection, The Volcani Center, P.O.
