Abstract

  Temperature-dependent development studies of two aphid species, A. egomae and A. gossypii occurring in green perilla greenhouse were conducted at 15~35℃, and 16:8 (L:D h) of light period in the laboratory. The mortality of two aphid species was high in young stages (1st and 2nd). In A. egomae, the mortalitiy increased with increasing and decreasing temperature: the mortalitie at 15℃ and 35℃ were 22.3% and 15.6%, respectively. While the mortalities of A. gossypii increased with increasing temperature: the mortality at 35℃ was 50.0%. The developmental periods of A. egomae and A. gossypii ranged from 20.8days to 5.4days and from 22.6days to 9.1days at 15℃ to 30℃ of temperature resion, respectively, and were 7.2days and 10.7days at 35℃ for each species. The lower developmental threshold temperatures for total nymphs of A. egoame and A. gossypii were 9.9℃ and 4.9℃, respectively and an effective degree-days (DD) for the developmental completion of total nymph were 108.0 DD for A. egomae and 221.2DD for A. gossypii. In green perilla greenhouse, the occurrence period of A. gossypii was earlier about 15 days than that of A. egomae. When the occurrence period of two aphid species was estimated by degree-days based on lower threshold temperatures, A. gossypii occurred earlier than A. egomae in the field. A. gossypii occurred from early April and showed dominant position to late May compared with A. egomae. Whereas, A egomae started to occur from mid April and then were abundant after late May followed by abrupt population crash around late July.
