Implication

Comparative study demonstrates botanical extracts suppress aphid abundance and reproduction in Chaitophorus leucomelas, highlighting their potential as eco-friendly bio-insecticides.

Key Points

To evaluate and compare the insecticidal effects of Dittrichia viscosa aqueous extracts, alone and with a bio-adjuvant, against synthetic insecticides on the life history and biochemical traits of Chaitophorus leucomelas.
Assessed winter-phenotype sexuparae of the black poplar leaf aphid (Chaitophorus leucomelas) exposed to D. viscosa aqueous extract, a 1:1 ratio with Silene fuscata bio-adjuvant, or thiamethoxam/lambda-cyhalothrin.
Measured aphid abundance, fecundity, demographic parameters (net reproductive rate, intrinsic growth rate, multiplication rate, generation time, doubling time), and lipid-carbohydrate energy reserves.
Aqueous extracts of D. viscosa significantly reduced aphid abundance, with the 1:1 bio-adjuvant mixture demonstrating pronounced insecticidal activity (P < 0.05).
Synthetic insecticides caused the strongest disruptions to lipid-glucidic energy reserves, fecundity, net reproductive rate, and intrinsic growth rate compared to plant extracts (P < 0.05).
The full synthetic dose significantly altered multiplication rate and mean generation time, whereas aphid doubling time exhibited relative stability across treatments.
