The essential oil from seed coats of Thuja orientalis L. (Family cupressaceae) obtained in an yield of 1% has been studied for its antimicrobial activity against 6 bacteria and 5 fungi using filter paper disc agar diffusion technique. The oil has shown good to moderate activity of the oil against all six test bacteria. The activity of the oil against S. typhi has been found remarkable at 1:1000...

Chamaecyparis are ornamental plants that are used extensively in temperate-zone landscapes worldwide. However, due to their low tolerance to environmental stresses Chamaecyparis often perform poorly in urban landscapes. The objective of this research was to evaluate rootstocks of selected Cupressaceae taxa to determine their adaptability to poor drainage and high temperatures found commonly in ...

Fluted pumpkin (Telfairia occidentalis Hook. F), is an under-utilized leafy vegetable cultivated and consumed for its valuable nutrients minerals playing a crucial role in combating micronutrient deficiencies. This shrub dioecious, exhibiting distinct differences sexual morphology. The study aims to contrast the phytochemicals, physico-chemical mineral profiles of female male fluted leaves. See...

Abstract The cypress bark beetle, Phloeosinus aubei (Coleoptera, Curculionidae, Scolytinae) prefers to build breeding galleries in decaying host trees. However, volatile cues specific or actively infested trees have not yet been reported. Any such information would be useful for the management of this invasive, wood-boring species that has become established across Europe temperate zone and is ...

The taxonomic status of B. terricola Kirby and B. occidentalis Greene has long been questioned. However recent COI gene sequence data suggests that B. occidentalis and B. terricola do represent good biological species. In this paper we test the hypothesis that B. terricola and B. occidentalis are conspecific by using independent morphometric and genetic (RAPD) data. For comparison we also analy...

The western flower thrips, Frankliniella occidentalis (Pergande), and the sweetpotato whitefly, Bemisia tabaci (Gennadius), are both invasive insect pests and are present in most of the same agricultural crops without a clear dominance of either species. Here, intra- and interspecific competition in B. tabaci and F. occidentalis was determined under controlled experiments. The results showed th...

It has been shown that many insects have Enterobacteriaceae bacteria in their gut system. The western flower thrips, Frankliniella occidentalis Pergande [Thysanoptera: Thripidae], has a symbiotic relation with Erwinia species gut bacteria. To determine if other Thripidae species have similar bacterial symbionts, the onion thrips, Thrips tabaci, was studied because, like F. occidentalis, it is p...

Effect of the leaves suspension Cassia occidentalis on elimination excess iron from artificially overloaded rabbits was studied. Leaves C. (250mg/kg) were used for rabbits. Rabbits divided into three groups; five weeks and then treated with selected herb four weeks. Iron concentrations in serum body organs like heart, liver kidneys assayed all groups after overloading jectosol plus injections a...

Three evergreen (Laurus nobilis, Viburnum tinus and Thuja plicata) and two autumnal abscission deciduous trees (Cydonia oblonga and Prunus domestica) have been investigated for the presence (zymogram and immunodetection) and functionality (post-illumination chlorophyll fluorescence) of the thylakoid Ndh complex. The presence of encoding ndh genes has also been investigated in T. plicata. Wester...
