Phytosanitary irradiation in South Asia

  Irradiation has the potential to solve phytosanitary problems related to trade in South Asia. In general, it is the phytosanitary treatment most tolerated by fresh agricultural commodities. Irradiation technology is available in some countries of the region but is only used for phytosanitary purposes for mangoes in India exported to the United States of America since 2007. In this review,...

Purification and characterization of an endo-beta-D-xylanase from major soldier salivary glands of the termite Macrotermes subhyalinus with dual activity against carboxymethylcellulose

  An enzyme with apparent dual functions as a xylanase and carboxymethylcellulase was purified from the major soldier salivary glands of the termite Macrotermes subhyalinus. The preparation was found homogeneous by gel electrophoresis after successive chromatography on anion-exchange, cation-exchange and hydro- phobic interaction columns. The specific activities towards carboxymethylcellulose and...

Contribution of mosquito vectors in malaria transmission in an urban district of Southern Cameroon

  In order to observe the role of vectors in malaria transmission in an urban area, a 12-month longitudinal entomological survey was conducted from January to December 2007 at Ekombitié, a central district of Ebolowa, south Cameroon. Mosquitoes captured indoors by human volunteers were identified morphologically. Among the 14.468 mosquitoes captured, three vectors were...

Damage assessment and management of cucurbit fruit flies in spring-summer squash

  Cucurbit fruit fly, Bactrocera cucurbitae (Coquillett), is one of the most important pests of cucurbits, and squash (Cucurbita pepo Lin.) is highly prone to damage by this pest in Nepal. Because of the difficulties associated with the control of this pest by chemical insecticides, farmers experienced great losses in cucurbits. Therefore, a participatory field experiment was...

The theoretical approach of ecoplexivity focusing on mass outbreaks of phytophagous insects and altering forest functions

  Epidemics of forest insects can have deep impacts on ecosystem functioning and dynamics, with consequences for forest economics and forest carbon feedback to climate change. Despite the many roles that insects fulfil in terrestrial ecosystems, their importance in nutrient cycling is not well known (Kosola et al., 2001). The only instances where herbivores are recognized to have a large effect on ecosystem...

Histological study on the body wall of Ascaridia galli (Nematoda)

  The body wall of Ascaridia galli has been investigated using 1-2 µ thick sections and stained with Toludin Blue. It is found to consist of three layers, cuticle, hypodermis or subcuticle and muscle layer. The cuticle in turn consists of three layers namely cortex or upper layer deeply stained with TB, 1.7 µ in thickness, middle layer or matrix 3.15 µ in thickness with no distinct...

We studied the habitat association and movement patterns of the Lycaenidae species, Lycaena helle using the mark-release-recapture method in a heterogenous natural habitat of West Khentey in Northern Mongolia. Butterfly individuals were collected using nets during a standardized one hour sampling in different biotopes. L. helle was found to predominantly inhabit the wet mesophile grasslands and herb meadows,...

Plasmodium and intestinal helminths distribution among pregnant women in the Kassena-Nankana District of Northern Ghana

  Parasitic infection during pregnancy is a major cause of anaemia in Africa. Social and environmental risk factors for the transmission of human parasites vary according to geographical location. Knowledge of the geographical distribution of parasitic helminths and malaria parasites is key to any interventional programme. Thus, in August-November 2005, a hospital-based study was conducted on 300 pregnant women...

Diversity of aphids in the central rift valley of Ethiopia and their potential as vectors for Ethiopian Pepper Mottle Virus (EPMV)

  Pepper mottling is an endemic and important disease of pepper in Ethiopia. It is caused by non-persistently aphid transmitted Ethiopian Pepper Mottle Virus(EPMV) (Potyvirus, Potyviridae). The disease occurs at epidemic level in the region. The exact roles of aphid vectors in the field epidemiology of the virus are not known. Identifying the roles of aphid vectors is useful in forecasting the epidemics of...
