large cages with M . anisopliae -treated pots.
While these delivery systems show promise in
the laboratory, clay pots have not been ef ective
as resting traps in all areas (van den Bijllaardt et
al. , 2009), and may require an attractant to
infect large numbers of mosquitoes in areas of
low malaria transmission and low mosquito

densities. Outdoor odour-baited stations (OBS)
have been developed containing M . anisopliae
spores. These hut-like devices, measuring 1.5 m
× 1.5 m × 1.5 m, were fi tted with spore-treated
bal es and baited with carboxylic acids,
ammonia and carbon dioxide (Fig. 5.9).
Collections were made from inside the OBS and
