The effect of Melia azedarach extract on the activity of NADPH-cytochrome c reductase and cholinesterase was studied in Spodoptera frugiperda. Larvae were fed an artificial diet containing fruit extract and their midgut was used for enzyme determination. As compared to the control, consumption of th...

Description
Summary:The effect of Melia azedarach extract on the activity of NADPH-cytochrome c reductase and cholinesterase was studied in Spodoptera frugiperda. Larvae were fed an artificial diet containing fruit extract and their midgut was used for enzyme determination. As compared to the control, consumption of the extract containing diet resulted in a 31% inhibition of the cholinesterase activity and a 34% activation of the NADPH-cytochrome c reductase activity. In the cockroach Leucophaea maderae, the effect on reductase activity was even more pronounced (43%).
