ABSTRACT

A field study was carried out over 27 weeks in the south Batinah region of Oman to assess the efficiency and cost-effectiveness of different strategies for vector control of malaria. Three larviciding strategies for Anopheles spp. were applied to intervention areas and compared with a control area, with over 2000 breeding sites monitored for 6 months. The normal method of spraying 1 ppm temephos larvicide fortnightly was found to be less efficient and less cost-effective than using 0.5 ppm temephos applied weekly. A third, more environmentally favourable method, to search for vector larvae and treat only those breeding places, was more effective than fortnightly spraying but less effective than the weekly half dose and was the most expensive strategy

ABSTRACT

A large scale field trial under natural conditions was conducted to observe biological effects of methoprene on mosquito immature and mature stages. In addition non-target invertebrates [N. T. Os] in the treated breeding places were also checked for any adverse effect. One dose of Altosid briquet formulation one briquete per 100 sq. ft. and two dosages 250 ml/hect. and 300 ml/hect. of liquid SR-10 methoprene were tested. Negligible% [less than 1%] adult mosquitoes emerging from pupae were observed during the first week after treatment with briquets or 300 ml/hect. On 18


h day of observation after treatment only 50% adults emerged from breeding places treated with 300 ml/hect. and same% from treated with briquets but on the 21


t day after treatment. Morphological abnormalities were noticed among the surviving adults, emerging between 6-15 days after treatment. Significant sex proportion distortion was also noticed among the apparent normal adults emerging between 3-12 days after treatment. Both the formulations of methoprene were found to be very safe in handling and for N. T. Os
