Effect of the infestation by Aphis nerii and Tetranychus urticae on the vase live period of jasmine flowers under glasshouse

Abstract EN

This study was carried out to study effect of infested jasmine flowers (Jasmine spp.

Family Oleaceae) by Aphis nerii (Boyer) (Hemiptera:Aphididae) and Tetranychus urticae Koch.

(Acari: Tetranychidae) on the vase life period (the flowers life after picking) of jasmine flowers under glasshouse conditions at two locations, El-Orman Garden (Giza Governorate) and International Garden (Alexandria Governorate) during successive season 2018.

This is because vase life period is very important parameter in cut flowers and there are many factors affected on it.

Therefore this study divided into two parts, first part studied effect of infested jasmine flowers by A.

nerii and T.urticae on the vase life period of jasmine flowers after picking.

Second part studied effect of infested jasmine flowers by the same pests on the internal components of these flowers which correlated with vase life period such as total sugar and total protein.

Results showed that the infestation by A.

nerii reduced the vase life period of jasmine flowers after picking more the infestation byT.

urticae compared to control (which non infested by the same pests).

Also results showed that the infestation by A.

Nerii reduced total suger and total protein at the infested jasmine flowers more than the infestation by T.urticae compared to control.

Lastly, results showed that the infestation by A.

nerii and T.urticae changed the number and arrange of the protein banding patterns (amino acids) of infested jasmine flowers petals compared to control.
