Abstract

Current experiments were carried out to find out the comparison between effectiveness of the insect infestation with Jasmine Thrips, Thrips orientalis (Bagnall) (Thripidae: Thysanoptera) and Rose Aphid, Macrosiphum rosae L. (Aphididae: Hemiptera) who infested jasmine plants on the quantity and quality characteristics of jasmine essential oil. Experiments were carried out under greenhouses on Jasminum grandiflorum (Oleaceae) during season 2022 at two areas (Governorates); Dokki area- Greenhouses of Agricultural Research Center- Giza Governorate and International Garden- Alexandria Governorate

Data obtained indicated that effectiveness of insect infestation with M. rosae was more effective than with T. orientalis on most quantity and quality characteristics of jasmine essential oil. In terms of quantity characteristics, data obtained indicated that the annual production of jasmine volatile oil (amount of volatile oil that was extracted from 1 kg jasmine flowers which did not infested with any insect) was about 3 gm, While amount of volatile oil that was extracted from 1 kg jasmine flowers which infested with T. orientalis was about 2.5 gm and amount of volatile oil that was extracted from 1 kg jasmine flowers which infested with the other insect M. rosae was about 2.2 gm. On the other hand, in terms of quality characteristics of jasmine essential oil, data obtained indicated that effectiveness of insect infestation with M. rosae was more effective than with T. orientalis on the most quality characteristics of jasmine essential oil.
