Plant latex, the source of natural rubber, has been of interest to mankind for millennia, with much of the research on its rheological (flow) properties focused towards industrial application. However, little is known regarding the rheology of the native material as produced by the plant, a key factor in determining latex's biological functions. In this study, we outline a method for rheologica...
The medicinal plants have been selected for thorough studies from indigenous folk medicines, Ayurvedic, Unani and Siddha systems of medicines. The aim of this study deals with the comparative evaluation of anti-inflammatory activity of the bark of Ficus bengalensis in plants of different age. The anti-inflammatory activity was evaluated by rat paw edema model induced by carrageenan for acute in...
A simple molecular tool was developed and tested to identify seven mealybug species found in North American vineyards: Pseudococcus maritimus Ehrhorn, Pseudococcus viburni (Signoret), Pseudococcus longispinus (Targioni-Tozzeti), Pseudococcus calceolariae (Maskell), Planococcus ficus (Signoret), Planococcus citri (Risso), and Ferrisia gilli Gullan. The developed multiplex PCR is based on the mit...
In the tropical African region the entire drosophilid genus Lissoceplzala and Drosophila $mu species group have evolved a close association with endemic figs (Ficus spp., Moraceae). We previously described the biology of a few of these figdependent drosophilids (Lachaise, 1977). We report here on a further investigation in evergreen rainforests, mainly in western Africa, that has yielded inform...
PURPOSE This study was aimed to evaluate general toxicity, anti-oxidant activity and effects of Ficus carica leaves extract on ischemia/reperfusion injuries. METHODS Antioxidant activity, total phenolic and flavonoid compounds of 70% methanolic extract of Ficus carica leaves were measured. The general toxicity test was carried out by brine shrimp lethality assay. Isolated hearts of male rats ...
The fig pollinating wasps (Hymenoptera: Agaonidae) have obligate arrhenotoky and a breeding structure that fits local mate competition (LMC). It has been traditionally assumed that LMC organisms adjust the sex ratio by laying a greater proportion of male eggs when there is superparasitism (several foundresses in a host). We tested the assumption with two wasp species, Pegoscapus silvestrii, pol...
The obligate mutualism between pollinating fig wasps in the family Agaonidae (Hymenoptera: Chalcidoidea) and Ficus species (Moraceae) is often regarded as an example of co-evolution but little is known about the history of the interaction, and understanding the origin of functionally dioecious fig pollination has been especially difficult. The phylogenetic relationships of fig wasps pollinating...
Opuntia ficus indica cladodes possess a protective action against ethanol-induced ulcer in the rat. The major components of cladodes are carbohydrate polymers, mainly mucilages and pectin. To clarify the cytoprotective effects of cladodes on experimental ethanol-induced ulcer in rat, mucilages and pectin were extracted and were administered instead of cladodes. The above mentioned effects induc...
The many species of figs (Ficus, Moraceae) have evolved a variety of reproductive phenologies that ensure the survival of both the fig plants and their short-lived, species-specific, pollinating wasps. A phenological study of 28 male and 23 female plants of a dioecious hemiepiphytic fig, Ficus tinctoria, was conducted in Xishuangbanna, SW China at the northern margin of tropical SE Asia. In con...
Certain Ficus spp. are dependent on wasps for pollination. The invading wasps usually shed their wings on entering a fig through the ostiole; and during attempted or successful egg deposi t ion, transfer pollen to the female flowers and then die. A gall forms around each egg, and within the gall develops a male or a female wasp. Male wasps are the first to emerge from galls, and they then ferti...
