Indoxacarb LC50 treatment significantly reduced pupation and adult emergence compared with the equivalent control.
Verbatim
e1“The efficacy of Avaunt (Indoxacarb 15% EC) on newly ecdysed 2nd and 4th instar Spodoptera littoralis (Boisd.) larvae was evaluated”
e3“The total development period of the subsequent larval instars following the treatment of 2nd or 4th instars by their respective LC50 Indoxacarb was significantly extended by 2.8 and 3 days, respectively”
e4“Furthermore, percentage pupation and adult emergence were significantly less than their equivalent control”
e5“The biochemical study carried out on 2nd and 4th instar larvae, 24 h following their feeding on castor oil bean leaves treated by their determined LC50 of Indoxacarb, showed that the treatment of 2nd instar larvae caused a 32.6% and 82.7% decrease in the content of carbohydrates and lipids in larvae than their value in the control”

- Association 2nd instar larvae were more susceptible to Indoxacarb than 4th instar larvae (LC50 0.63 ppm vs 2.0 ppm).
- Observation Total development period of the subsequent larval instars was extended by 2.8 and 3 days after LC50 Indoxacarb treatment of 2nd and 4th instars, respectively.
- Intervention effect Carbohydrate content of 2nd instar larvae decreased by 32.6% after LC50 Indoxacarb treatment compared with the control.
- Intervention effect Lipid content of 2nd instar larvae decreased by 82.7% after LC50 Indoxacarb treatment compared with the control.
- Intervention effect Carbohydrate content of 4th instar larvae was reduced by 56.4% after Indoxacarb treatment compared with their control.
- Intervention effect Lipid content of 4th instar larvae was reduced by 76.5% after Indoxacarb treatment compared with their control.
- Observation Total protein of 2nd instar larvae increased by 8.7% after Indoxacarb treatment.
- Intervention effect Total protein of 4th instar larvae decreased by 24.9% after Indoxacarb treatment compared with untreated insects.
- Observation Alpha and beta esterase and glutathione S-transferase activities increased significantly in treated larvae.
- Observation Acetyl choline esterase and acid phosphatase activities decreased significantly in treated larvae.
