Background and Objective: The application of organic fertilizers and fertilizers containing phosphorus and potassium can increase the resistance of crops against pests. This study aimed to investigate the effect of algae extract (Stemplex) and potassium phosphate fertilizer (Dekap) on the biostatistics of the black bean aphid (Aphis fabae).
Material and methods: This study was conducted to investigate the effect of fertilizer treatment (Dekap, Stimplex and control) on the biological statistics of black beet aphids under controlled conditions of temperature (25±2 C0) and humidity (60%±5). In addition, the light period was 14 hours of light and 10 hours of darkness. Beans were sprayed three times with the recommended concentration of Dekap fertilizer (1 ml per liter) and Stemplex (2 ml per liter). The first time was at the planting stage and the subsequent times were repeated at intervals of two weeks after planting the faba bean. The aphids were reared on each treatment for three generations. The data were analyzed using the age-stage, two-sex life table approach.
Results: The results of experiments on the effect of two fertilizers on bean plant showed that different treatments compared to control treatment had a significant effect on biological characteristics and outlines of the black beet aphid life table. The maximum duration of the immature stages was 7.83±0.26 days on the Stemplex treatment. The highest intrinsic population growth rate (r) was obtained on control treatment (0.51±0.009 per day) and the lowest r value was related to Stemplex fertilizer treatment (
