Host-Plant Variations Affect the Biotic Potential, Survival, and Population Projection of (Hemiptera: Aphididae).

The green peach aphid, Sulzer (Hemiptera: Aphididae), a polyphagous insect pest is a major threat to a wide range of crops worldwide. Aiming to evaluate the life history traits of , feeding on different host plants, we used five vegetables: cabbage, (Brassicaceae); chinese cabbage, (Brassicaceae); chili pepper, (Solanaceae); crown daisy, (Asteraceae); and eggplant, (Solanaceae). TWOSEX-MSchart software was used for the statistical analysis about the age-stage, two-sex life table theory. The highest fecundity (69.65 individuals) rate of , intrinsic rate of increase ( = 0.425 d), finite rate of increase ( = 1.531 d), net reproductive rate ( = 69.65 offspring), and shortest mean generation time (T = 9.964 d) were recorded on the chili pepper plant. Whereas, lower fitness occurred on cabbage. The findings attained from population growth parameters indicate that chili pepper is the most susceptible plant, while cabbage is resistant to aphids. Population projection results also supported this statement, as the final total population size on cabbage was significantly lower than other plants. The reported information would be useful for devising integrated pest management programs, particularly those involving . This information also suggests the adaptability of causing economic damage to these vegetable cultivars.
