Seventeen compounds, including a new lanostane triterpenoid, 24(Z)-1β-3β-dihydroxyeupha-7,24-dien-26-oic acid, have been isolated from the methanolic extracts of two samples of Jordanian propolis collected from two different places with different dominant flora. The structures of the isolated compounds were elucidated by spectral methods including IR, UV, MS and 1- and 2-D NMR.

Population trends of grape root phylloxera were carried out in highly infested field in Husban, Madaba district in 2005. Mean numbers of eggs and mobile stages, showed a peak in early July. Eggs started to appear in late May, and Nymphs started to appear in late June. Numbers of all stages started to decrease in early August .Galls were noticed on examined roots in 2005 as compared with the 2004 season. There were significant differences among pesticide soil treatments for all stages in the two ...

Propolis is collected by honey bees to seal cracks in the hive, to strengthen borders of combs and as medication for various pathogenic infections. In the current field study, experiments were carried out in two locations; the University of Jordan main campus (location 1) with dominant pine trees to collect propolis (Type 1), and Al- Hashmeah (location 2) with dominant oak trees to collect propolis ( Type 2 ). The experiments were carried out during the period from June 2003 to September 2004. T...
Population dynamics of root form of grape phylloxera, Daktulospharia (Vites) vitifoliae Fitch. (Homoptera: Phylloxeridae ) were carried out in the field in 2004. Mean number of eggs, nymphs and adults showed peaks in mid-July and early August, respectively. All stages disappeared in late August. There were no galls noticed on the examined roots throughout this study. Treatments included two insecticides, imidacloprid and thiamethoxam and control. The insecticides were applied to the foliage of t...

Propolis is a natural product widely consumed in folk medicine. The present study was carried out to investigate the antibacterial activity of Jordanian propolis, collected from two locations with two different dominant floras (Type1; Pine trees and Type ll; Oak trees). Zones of inhibition and minimum inhibitory concentrations (MICs) were determined on methicillin resistant Staphylococcus aureus (MRSA), multidrug resistant Escherichia coli and standard strains of both bacteria. Propolis Type I a...

An experiment was carried out to study the effects of four pollination techniques; Bumblebees (Bombus terrerstris L.), plant growth bioregulator (PGB) (Parachlorophenoxy acetic acid), hand vibration, and control (natural pollination) on tomato ( Lycopersicon esculentum Mill) production in greenhouses. Bumblebees showed no problem in visiting flowers at a temperature range of 17-42 ° C during the day and 2-14 ° C at night. Bumblebee pollinated plants produced a yield per plant which was significa...
