Use of larvacide in the Solomons
A short time ago the National RAM Committee was asked to help fund the purchase of a quantity of larvacide for use in the Solomons. This was a first for us, but after some investigation we agreed. The simplest way to describe the effects of larvacide is to quote directly from the website of BASF and an item on Abate ® larvacide
When applied to standing water where mosquitoes and other insects breed,
Abate kills the larvae before they develop into mature insects. In effect,
it short-circuits the cycle that disseminates the pathogen to humans. Several
vector-borne diseases, such as malaria and dengue fever, may be strongly associated
with the domestic storage of drinking water. One option, where there is a significant
risk of disease, is to prevent disease vectors from breeding in stored, domestic
drinking water. Temephos, the active ingredient in Abate is recommended by the
World Health Organization for addition to drinking water
A short report, PDG Peter Thomas follows.
The "Abate" larvacide we supplied to the malaria control program in Honiara has been used most
effectively to control mosquito larvae. The program was held up for a couple of months, until the heavy
rains eased, and now in conjunction with a special grant from the World Bank has been used to clean up
drains and waterways within the urban area and adjacent squatter settlements. The "Abate" is used in
areas that cannot be drained, or the flow of water is insufficient, and according to the team who check
such areas and collect larvae where they can, is very effective. Larvae counts are dramatically down
and stay down. So far 6 twenty kg drums of granules have been used.
I travelled to White River, a low-cost housing settlement on the edge of town, and witnessed one of the
clean-up teams checking watercourses and stagnant water areas and applying "Abate". I was
impressed; they were doing a very thorough job.
The picture shows testing for mosquito larvae at White River settlement.
This work is an integral part of the overall malaria control program in the urban area.
The use of treated
bednets, the spraying of residual insecticide in all dwellings, good treatment protocols and reduction of
mosquito breeding areas, has seen a dramatic reduction in the Incident Rate for Honiara Urban Area to
82/1000. Funding from The Global Fund, AusAID, The Rotary Foundation (our 3H Grant) and RAM
have all contributed to this outstanding achievement.
