Abstract
The experiments were conducted in the laboratory Plant Protection Research Institute Dokki- Giza, to study the effect of Anethum groveolenus Dill, Ambrosia maritime Damaseia extract, Cumminumcyminum Cumin; Syzyguim aromaticum Clove and Alliummaritime Garlic on activity of some enzymes in( Tuta absoluta Meyrick) on tomato plants were investigated. After the tested compounds application, the results revealed that these compounds had various effects on the activity alkaline phosphatases, α and β esterases and carbohydrates hydrolyzing enzymes ( trehalase, invertase and amylase (. The enzyme activity reduced or increased significantly. Activity of alkaline phosphatases, α and β esterases were higher in Damasiea on T. absoluta, in comparison to control. The percentage of increase of alkaline enzymes activity were +22.28 and +17.38 and +13.34 % in T. absoluta respectively. Also, in cumin and garlic extracts treatments. Generally, in case of T. absoluta treatments, the results of damasiea extract indicated high increase (+40.1% in comparison to control) in activity of beta- esterases and invertase enzymes but high decrease (+45.9%), in alpha- esterases activity only.
The results indicated that the damasiea extract had direct effects on the metabolism in the body Tuta absoluta.
