The application was registered suo-motu based on the news item titled “Neglected Katora Houz in Hyderabad’s …
Fly ash is produced in huge quantities by the various thermal power stations in India. This thermal waste has been employed as a carrier material in the preparation of a biopesticidal water dispersible powder (WDP) formulation for use against mosquitoes. In the present investigation, this newly developed fly ash based …
A preliminary screening was carried out on five plants viz., Azadirachta indica, Citrus medica, Murraya koenigii, Ocimum tenuifloreum and Ricinus communis for their repellent activity against mosquitoes. The repellent activity was studied under natural conditions in the field making use of the traditional knowledge as background. Field observations were undertaken …
This study was carried out to evaluate mosquito repellent and oviposition deterrent activities of Solanum nigrum against malaria vector Anopheles stephensi. Hexane extract of the seeds of Solanum nigrum was used for repellent and oviposition deterrent activity against mosquito vector Anopheles stephensi Liston (Diptera: Culicidae) in laboratory bio-assays.
Mosquito control with the use of insecticides is faced with the challenges of insecticide resistance in disease vectors, community refusal, their high cost, operational difficulties, and environmental concern. In view of this, integrated vector control strategies with the use of larvivorous fishes such as Guppy (Poecilia reticulata) and Gambusia (G. …
Lymphatic filariasis (LF) is a globally significant disease, with 1.3 billion persons in 83 countries at risk. A coordinated effort of administering annual macrofilaricidal prophylactics to the entire at-risk population has succeeded in impacting and eliminating LF transmission in multiple regions. However, some areas in the South Pacific are predicted …
With rain comes mosquitoes. So, three days into the monsoon’s onset in the capital, the Delhi Zoo has started an anti-malaria campaign to prevent mosquito menace affecting its animals. Apart from regular with spraying and fogging exercises, the zoo has been relying on larvae-eating Gambusia fish to prevent the breeding …
Mosquitoes act as a vector for most of the life threatening diseases like malaria, yellow fever, dengue fever, chikungunya ferver, filariasis, encephalitis, West Nile Virus infection, etc. Under the Integrated Mosquito Management (IMM), emphasis was given on the application of alternative strategies in mosquito control. The continuous application of synthetic …
USE of insecticides to get rid of mosquitoes is known to be detrimental to the environment and human health. A finding on how larvae of mosquitoes which cause dengue and filariasis can be killed in an eco-friendly way, therefore, holds significance. Researchers at the Annamalai University in Tamil Nadu have …
Rapidly emerging insecticide resistance is creating an urgent need for new active ingredients to control the adult mosquitoes that vector malaria. Biopesticides based on the spores of entomopathogenic fungi have shown considerable promise by causing very substantial mortality within 7–14 days of exposure. This mortality will generate excellent malaria control …
BIOLOGISTS have just woken up to the presence of chemicals that can dictate the egg-laying preferences of a mosquito. A whiff of the chemical can make a gravid insect avoid a water pool. Is this the malaria solution the world is waiting for? A team of ecologists at University of …
Munia Devi and her son Bholua look forward to the world-famous cattle fair that takes place here every year. They can't afford to buy any animal, but they make a neat packet selling elephant dung. Elephant dung is known as the poor man's mosquito repellant. When burnt, it gives out …
Ajai Shukla / Tezpur (assam) May 05, 2009, 0:55 IST During the Second World War, Field Marshall William Slim, commander of the 14th Army in Burma, discovered that the anopheles mosquito was causing more casualties to his men than the Japanese. Ruthlessly practical, he decreed that catching malaria was a …
ONTHESPOT - NRS HOSPITAL The pond at NRS; (above) litter dumped on the bank. Pictures by Bishwarup Dutta To battle the mosquito menace on its premises, Nil Ratan Sircar Medical College and Hospital (NRS) will use its 1.3-acre pond for pisciculture. The NRS authorities had written to the Calcutta Municipal …
Decades ago, in the wake of increasing chemical pesticide-related deaths, researchers sought to reinvent commercially viable alternatives to conventional pesticides. By the 1970s, optimism was high that future pest control schemes would increasingly incorporate novel methods including the use of biocontrol agents. Application of the sterile male technique in mosquito …
policymakers in India swear by the insecticide ddt to contain sand fly, the kala-azar vector. There are alternatives to using chemicals, a group of researchers has found by studying 50 villages in five kala-azar endemic districts in Bihar. The disease is most prevalent in the state. Critics say the study …
There are several procedures to control mosquitoes by chemical, mechanical, genetical or biological means. Biological control of mosquito larvae by the application of natural animal products is one of the important techniques, which is cheap, easy-to-use and environment friendly. (Correspondence)
