Abstract
The present study aimed to evaluate the physiological changes and chemical
components of haemolymph affected by three botanical extracts, namely volatile garlic oil, volatile
peppermint oil and Neemazal T/S formulation in the haemolymph of C. capitata 3rd instar larvae under
constant laboratory conditions of 25 ± 1ºC, 75±5 RH % and 12/12 L/D at Plant Protection Department,
Faculty of Agriculture, Zagazig University, Egypt. Artificial larval rearing medium was treated with
two concentrations of 400 and 800 ppm for each botanical extract used as they are the most effective
concentrations. Results showed that, in respect to carbohydrate, protein and lipid hydrolyzing enzymes,
garlic oil recorded the highest enzyme activity valued 325.67, 297.33, 626.67 μg/ml, respectively; while
Neemazal formulation recorded the lowest one of 112.67, 8.08, 44.33 μg/ml, respectively. In case of
total free amino acids, Neemazal formulation recorded the highest level of 263.33 μg/ml, while garlic
oil recorded the lowest one of 91.97 μg/ml. All botanical extracts reduced the total amount of mineral
elements. However, Neemazal formulation was the most effective in reducing amount of sodium,
potassium, nitrogen, phosphorus and calcium indicating 4.91, 29.00, 4.74, 1.82, 251.83 μg/ml,
respectively. Results clearly revealed that all botanical extracts investigated reduced the proportion of
enzymes in the haemolymph of the 3rd instar larvae than in control. The increasing of concentrations
from 400 to 800 ppm increased the effects.
