Title

EFFECT OF TEMPERATURE ON THE BIOLOGY OF ALMOND GREEN APHID BRACHYCAUDUS AMYGDALINUS UNDER LABORATORY CONDITIONS

Pages

  1-16

Abstract

 The relationship between temperature and DEVELOPMENTAL RATE of BRACHYCAUDUS AMYGDALINUS Schout (Homoptera: Aphididae) was studied at six constant temperatures (10, 15, 20, 25, 27.5 and 29±0.7°C), 40±10 RH and a photoperiod of 12: 12 (L: D). The linear regression model was used to describe DEVELOPMENTAL RATE as a function of temperature.The duration of nymphal stages decreased from 14.04 to 5.8 days at 10 to 27.5°C, respectively. However, it increases to 8.39 days at 29°C. The mortality rate of the first nymphal stage was high at 30°C so that none of them could develop to fourth stage. The lowest (31%) and highest (89%) survival rate were obtained at 29 and 10ºC, respectively.The Lactin-2 model was the best nonlinear model to describe the relationship between DEVELOPMENTAL RATE and temperature, suggesting the upper threshold temperature of 29-30°C.The linear regression revealed that the lower thermal threshold was -2.84°C, approximately the same temperature that makes this species active in nature. The life span of adult aphids was 6.74 days at 20°C. The following LIFE TABLE parameters have been recorded for B. amygdalinus at 20°C: intrinsic rate of increase (rm= 0.263 1/day) mean generation time (T = 11.49 days), doubling time (DT = 2.63 days), net reproductive rate (R0= 20.62) and gross reproductive rate (GRR = 40.59).
