PHYTOCHEMICAL AND TOXICOLOGICAL EFFECT OF CERTAIN PLANT EXTRACTS AGAINST THE COTTON APHID, Aphis gossypr'i GLOVER
Department of Vegetable Pests, Plant Protection Research Institute, Dokki, Giza, Egypt.
Abstract
Phytochemical constituents were separated and identified at the length ethanol
extracts of leaves of Lantana. Lantana camera 8. seeds of Cumin, Cuminum cyminum
and Golden shower, Cassia fistula. It is clear that, Cumin extract contained high
amounts of carbohydrates, glycosides and volatile oil while flavonoides, sterols and
triterpenes recorded moderate amounts. On the other hand, phenolic glycoside and
cardic glycoside were detected in slight amounts, while tanins and saponin were
found in trace amounts in cumin seeds. With respect of Lantana extract. it contained
moderate amounts of carbohydrates, glycosides, flavonoides, volatile oil and phelonic
glycoside, low amounts of sterols, triterpenes, tannins, cardic glycoside,
anthraquinone and alkaloids and trace amounts of saponins. As for Golden shower,
its screening showed high amounts of carbohydrates and glycosides, moderate
amounts of tanins, low amounts of sterols, triterpenes. alkaloids. saponins &
flavonoides and trace amounts of volatile oil.
The efficiency of ethanol extract from Cumin, Golden shower and Lantana
plants as expressed in LCSO and LC90 values against adults of Aphis gossypii Glover.
The ethanol cumin extract which gave 82% mortality at 1.50 mglcm concentration
had the best toxic effect. The extracts obtained from the three plants showed clear
insecticidal activity against the tested pest.
