Some of phytotoxic and antimicrobial compounds extracted from culture filtrates of Fusarium proliferatum FP85

Fusarium is one of the most important plant pathogens around the world which causes great damages to agriacultural crops. The fungus produces a wide variety of volatiles and bioactive metabolites like mycotoxins, fatty acids and hydrocarbons on artificial medium with antifungal, antibacterial, antiviral and phytotoxic properties. After 21 days inoculating the species Fusarium proliferatum FP85 […]

Seasonal monitoring of fruit fly, Bactrocera zonata (Saunders) and its parasitoids Trybliographa daci on guava fruit from Sindh Pakistan

Seasonal monitoring of fruit flies, Bactrocera zonata and Bactrocera dorsalis was carried out by collecting the infested guava fruits for recording the larval parasitoid under laboratory conditions; and weekly trap catches for fruit fly species were also recorded. The B. zonata and B. dorsalis pupae were collected from 01.11.2012 to 15.03.2013 at fortnightly interval. The […]

Woody plants diversity of two non protected tropical forests in Côte d’Ivoire (West Africa)

Floristic diversity of woody plants was studied in two Non Protected Forests (NPF) of Southern Côte d’Ivoire (West Africa) in order to promote their conservation. The sampling blocks method was used for floristic inventories. Each block was divided in 16 sampling plots of 25 m x 25 m subdivided in elementary sampling plots (5 m […]

Allelotoxic activity of Eucalyptus rostrata Schlecht. on seed germination and seedling growth of Chenopodium album L. and Portulaca oleracea L.

Eucalyptus rostrata is known to contain various substances that are allelopathic. The allelopathic effect of leaf (ERLAE) and bark (ERBAE) of Eucalyptus rostrata aqueous extracts was evaluated for their potential uses as control on seed germination and seedling growth of two noxious weeds; Chenopodium album and Portulaca oleracea. The biological activity of the two types […]

Distribution and plant diversity of mangroves in the west coast of Kerala, India

Mangroves in India account for about 5 per cent of the world’s mangrove vegetation and are spread over an area of about 4,500 km2 along the coastal States/UTs of the country. Various studies showed that mangrove vegetation cover only 1,095 ha in Kerala (Kurien, et al., 1994). According to another estimate, Kerala once supported about […]

First record of the Liphyra perplexa (Crusatcea: Decapoda: Leucosidae) in Indian waters, with DNA barcoding data

DNA barcoding has been advanced as a promising tool to aid species identification and discovery through the use of short, standardized gene targets. In the present study a species of crab, Liphyra perplexa was reported and was DNA barcoded for the first time in Indian waters. The study was carried out for identification of Lyphira […]

Influence of ammonia-nitrogen on the diversity of microalgae in clean and highly concentrated wastewater

The diversity of microalgae can be affected by different factors serving as source of their nutrients. The most promising factor which is highly variable for different clean and waste-water bodies is Ammonia-nitrogen (NH4-N). The NH4-N studied for different locations of the district Malakand showed a variation in their values in respect to different seasons. The […]

Some studies on the taxonomic status of the genus Aiolopus Fieber (Acrididae : Acridoidea: Orthoptera) from Pakistan

At the present orthopteran fauna in agricultural fields of Pakistan were investigated. The large numbers of specimens have been collected from different provinces of Pakistan during the year 2011-2012. Three species namely Aiolopus thalassinus thalassinus, Fabricius, A.thalassinus tamulus, Fabricius, and A.simulatrix simulatrix, Walker, of subfamily Oedipodinae were came in collection. However, the most dominant and […]

Biodiversity of fish utilizing intertidal estuary of poigar river during high-tide (North Coast of North Celebes, Indonesia)

This study was carried out to describe periodic change in fish occurrence in the estuary of Poigar River, particularly those entering the estuary at high tide in new moon and full moon phases. Sampling areas at both moon phases were the freshwater area at low tide and the water depth of 1.5-2.5 M at high […]

Autecological survey of Smyrnium cordifolium Boiss. in Rangelands of Iran

Nowadays due to genetic erosion and vegetation regress, investigation of autecology to determine ecological desire of rangeland plants is important and necessary. The autecology project of the S. cordifolium was performed in rangelands of in Southwest of Iran(Yasooj city) in 2013, Due to importance of this plant which have palatability in class (I) and high […]
