Assessment the effect of Thymus vulgaris (Lamiales: Lamiaceae) on biology of Pectinophora gossypiella (Lepidoptera: Gelechiidae) and Chrysoperla carnea (Neuroptera: Chrysopidae)


Hemat Z Moustafa, Heba Yousef

The insecticidal toxicity of Thymus vulgaris against Pectinophora gossypiella newly hatched larvae and its predator; the 2nd instar larvae of Chrysoperla carnea were evaluated under laboratory conditions. The LC50 values for P. gossypiella treated newly hatched larvae with T. vulgaris extract was 1.86 (g/ 100g diet) after ten days of treatment, While, the LC50 value was 626.97 (g/ 100g diet) for the 2nd instar larvae of C. carnea after seven days of treatment with T. vulgaris extract. The extract treatment elongated the larval and pupal period compared with control with a 92.31% adult emergence. Whereas, the total immature stages of C. carnea was 18.63 days after treatment compared with 16.1 days for the control with 75% adult emergence.
