I. Purpose To develop an experimental protocol
for collecting and identifying mosquito larvae
that, when implemented together with other
environmental measurement protocols developed by
the GLOBE Program, will 1.Provide valuable data
that relate environmental conditions to breeding
patterns of malaria-bearing and
non-malaria-bearing mosquitoes. 2.Increase the
level of understanding about malaria among
students, teachers, and communities in countries
where this disease is endemic.
- II. Background
- ?Malaria is a parasitic disease spread by
mosquitoes in the genus Anopheles. It causes more
than - 300,000,000 acute illnesses and more than
one million deaths annually, including the death
of - one African child every 30 seconds.
- ?Recent epidemiological trends include increases
in malaria mortality and the emergence of drug- - resistant parasites.
- ?Some experts believe that predicted climate
changes during the 21st century will bring
malaria to - areas where it is not now common.
- There are dozens of Anopheles species and
sub-species that are adapted to a wide range of - micro-environmental conditions encountered
in Madagascar's variable climate. These variable - conditions, along with increased population
mobility, actually reduce levels of immunity and - produce sporadic malaria outbreaks with
high mortality.
- III. Why GLOBE?
- GLOBE Program provides an ideal framework a
highly structured system for defining experiment - protocols that ensure consistent
procedures, a widely dispersed network of
observing sites, and a - centralized data collection and reporting
system. - ? Current GLOBE protocols for basic
meteorological and water quality are already in
place. - Current emphasis by GLOBE on developing stronger
national and regional programs focused on - environmental issues of national and
regional concern.

- V. Implementation in Madagascar
- Summer, 2005 GLOBE/Madagascar (Mr. Rafalimanana)
shared project with scientists and - ministry officials in Madagascar (the
University of Antananarivo, National Institute
for - Pedagogical Training, Ministry of Health,
Centre National dApplications et des Rescherches - Pharmeceuticques (CNARP), Ministry of
Education). - October 2005 With support from GLOBE Program
(Brooks and Boger), developed a draft - protocol for the collection and
identification of the mosquito larvae. Teachers
and students from - selected schools received training in this
new GLOBE protocols as well as basic
meteorological - and water quality protocols (in time for
mosquito breeding season). - Some difficulty in collecting samples, but no
difficulty distinguishing between Anopheles and - Culex larvae. Revisions to protocols
addressed sample collection difficulties and
classroom - interpretation.
- Spring 2006, first data reports from 2 schools.
- IV. Protocol Summary
- ? Identify and characterize potential mosquito
breeding sites. - ? Collect larvae samples with dip net (5 dips per
session). - ? Observe water quality, vegetation, and
potential larvae predators around collection
site. - Count larvae and identify at genus level as
Anopheles (which transmit malaria) or
non-Anopheles - (which do not transmit malaria).

- VI. Conclusions
- In less than one year, a new protocol has been
developed and implemented, primarily by the GLOBE
Program in - Madagascar.
- ? Government, education, and public health
officials have taken ownership of the project. - Preliminary data demonstrate the validity of the
project concept. They already show some
interesting data trends, - raise new questions, and suggest where
improvements can be made in this protocol.
