House-scale evaluation of bifenthrin indoor residual spraying for malaria vector control in India.

In an area of India where the main rural malaria vector, Anopheles culicifacies Giles, has developed triple resistance to DDT, HCH, and malathion sprayed indoors in antimalaria program, bifenthrin (10% wettable powder) was evaluated in a randomized house-scale trial between July 1999 and March 2000. Entomological impact of four serial doses of bifenthrin (25, 50, 100, and 200 mg/m2) sprayed in rooms in five villages was compared with malathion (2 g/m2) and unsprayed control. An.

Japanese Encephalitis epidemic in Anantapur district, Andhra Pradesh (October-November, 1999).

Epidemic of Japanese Encephalitis has occurred in Andhra Pradesh during October-November, 1999 affecting 15 out of 23 districts. In total, 873 cases with 178 deaths have been recorded up to the day 29.11.

Laparoscopic repair of Morgagni hernia in adult.

Foramen of Morgagni hernias require surgical treatment; laparoscopic repair is another option with lower morbidity. We describe a 35-year-old man with Morgagni hernia treated successfully by laparoscopy.

Blood meal identification by using Microdot ELISA in vector mosquitoes.

The blood meals of five mosquito species which are vectors for malaria, J.E. and Filaria were determined by using Microdot ELISA technique, which is a rapid and sensitive method.

Some aspects of changing behaviour of malaria vectors in tribal areas of India.

The field entomological studies and surveys carried out in 72 tribal districts out of 100 in seven penninsular States namely, Andhra Pradesh, Bihar, Gujarat, Madhya Pradesh, Maharashtra, Orissa and Rajasthan indicated that in most of the areas the vector mosquitoes encountered during the present study were almost the same as recorded by the earlier workers except that Anopheles fluviatilis James, 1902 was recorded in the areas of district Raipur, Durg, Bilaspur, Raigarh, Shahdol, Rajnandgaon, Barwani and Janjgir of Madhya Pradesh, and Sundergarh of Orissa during the present survey. This vector was not recorded in earlier studies by other workers. An.

Susceptibility status of malaria vectors to insecticides in India.

The use of chemical insecticides for control of malaria vector populations continues to be the mainstay of malaria control strategy in India. Monitoring vector susceptibility to chemical insecticides is an important activity under the National Malaria Eradication Programme to ensure judicious and effective use of chemical Insecticides. 72 entomological zones were established under NMEP in 1977 for undertaking entomological studies in the malaria problematic areas.

Malaria transmission during post-spray period of pirimiphos-methyl in Arunachal Pradesh.

Observations made for a period of four years from 1985 to 1988 on post-spray impact of pirimiphos-methyl (25 per cent Wp) on malaria vectors in Tirap district of Arunachal Pradesh showed that a low density (0.0 to 0.02 PMH) of Anopheles dirus was maintained in the areas sprayed with the insecticide at the dosages of 1 and 2 g/m2 from 1981 to 1984.

Blood Cholinesterase monitoring in spraymen involved in malathion spraying--a health protection measure.

The blood Cholinesterase (ChE) level of malathion in spraymen is continuously monitored through a "built-in warning system" existing under NMEP since the introduction of malathion spraying. The data available from the States of Maharashtra, Punjab and Gujarat revealed that, in spraymen of Punjab, the ChE level in 1988 and 1989 remained normal in about 99.8 per cent spray personnel, and in 1 out of 381 workers, the ChE level fell to 62.

Success of integrated methods of control of mosquitoes in India--a review.

The integrated methodology for the control of vectors of diseases as well as mosquitoes has become an accepted concept amongst the public health experts. The feasibility of adopting this approach in different situations for mosquito control as per field trials by various institutions has been reviewed in this article. This concept, to some extent, has been in vogue under National Malaria Eradication Programme since long in a practicable way.

Field trial of the effectiveness of indoor-spraying with pirimiphos-methyl emulsion for malaria control in a tribal area of Phulbani district, Orissa State, India.

A field trial of malaria vector control was conducted in Phulbani district, Orissa, during 1984 and 1985. Indoor-spraying of pirimiphos-methyl emulsion formulation was undertaken at an application rate of 2 g/m2 in two sections (population 14,692) of Nuagaon Primary Health Centre. Houses in two adjacent sections (population 21,450) were sprayed with DDT a water dispersible powder (wdp) formulation at 1 g/m2 for comparison purposes.
