In Vitro screening of larvicidal and insecticidal activity of methanolic extracts of Artocarpus heterophyllus, Artocarpus altilis and Piper betle

In Vitro screening of larvicidal and insecticidal activity of methanolic extracts of Artocarpus heterophyllus, Artocarpus altilis and Piper betle



Sindhu S Nair, Vaibhavi Kavrekar



The aim of this work was to evaluate the larvicidal and insecticidal
activity of the selected plants namelyArtocarpus altilis, Piper betle
and Artocarpus heterophyllus. The leaves of Artocarpus altilis and
Artocarpus heterophyllus and roots of Piper betle were subjected to
methanolic solvent extraction for the isolation of various bioactive
constituents. The evaluation of larvicidal activity was carried out
using late third instar larvae of Drosophila melanogaster. The
insecticidal activity of extracts was studied against adult Bruchus
pisorum, Tribolium castaneum, Sitophilus oryzae and was evaluated by
direct contact application method .Nucleic acids and protein contents
are regarded as important biomarkers of the metabolic potential of
cells, as these play the main role in regulating the different
activities of cells. Piper betle and Artocarpus heterophyllusextractshad
a reducing effect on the nucleic acid and protein content in the larvae
in a dose dependent manner whereas Artocarpus altilis extract did not
exhibit any significant larvicidal activity. Piper betle and Artocarpus
heterophyllusextractsshowed good insecticidal activity whereas A.altilis
extract showed poor insecticidal activity. The results of the present
study clearly indicate that Piper betle and Artocarpus heterophyllus
extracts can be developed as ecofriendly larvicides and were also quite
effective as insecticides for providing a better and excellent alternate
for the control of insects.

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal Abdullahi MG, Roslan U, Kamarudin M. K. A. Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view the night sky, on biodiversity, and ecosystems. Though, in recent years, with the use of new technologies sensors, which provide accurate information for determining of night lights at the area, most consideration were given for estimating artificial light at night within the urban areas. In this study, urban night lights within the cities of Nigeria was evaluated by monitoring data from the ground measurements using Sky Quality Meter (SQM-LU-DL) devices. Besides, the SQM was used at the zenith (upward direction) for maximum evaluating of artificial light at the sites. Differences in night sky bri...

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran Shadi Maleki, Abbas Mafi, Seyedeh Mahsa Hosseini Today, as an essential part and parcel of urban landscape that they play a major role in metabolism and create a lack of serious damage to urban life. This study performed to investigate the willingness of citizens to participate in activities to protect and develop landscapeof Tehran district 4. The research was descriptive and correlation method that is used for collecting information. The statistical population consisted of district 4 of Tehran. The sample size was determined 230 by using Cochrane method. A questionnaire was used to collect data. According to the research, 63.04 percent of citizens showed participation in a high level. Among the variables investigated how citizen participation in conservation and development of landscape, effective strategies to motivate citizens to participate,the reasons for la...

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin Adimasu Woldesenbet Worako   Land use land cover change (LULCC) is the result of the long time process of natural and anthropogenic activities that has been practiced on the land. GIS and remote sensing are the best tools that support to generate the relevant land use/cover change in the basin. This study was conducted in the Akaki River basin to detect land use land cover changes within the 30 years period (1985-2015) by using landsat imagery data acquired from the GCF. Supervised maximum likelihood algorithm classification were deployed to classify land use/cover into four prominent land use groups and data’s were processed by using ERDAS imagine 2014 and ArcGIS10.1 software. In the basin dominant LULC was agricultural land use which accounts around 56.28% and the second largest is built-up area by 31.51% and the rest, forest(11.9%) and water body(0.31%) coverage were takes t...
