In the paddy fields the same mosquitoes are found, and in additio 
sometimes N. nivipes. 
Stegomyia scutellaris may be found in the pools, but is more common i 
artificial receptacles. Practically no jungle was left, but low undergrowth 
grasses and sedges are common. 
. C ertain mosquitoes which are often met with in smaller cleared area 
m jungle country in Malaya were not found. These include several specie 
or Melanoconion, M. albivostris and Cidex mimeticus. 
In conclusion, as regards the diminution in the number of mosquitoe 
m any place it is obvious that the measures to be adopted will depend oi 
the species of mosquitoes present. 
Judicious selection of sites and extensive clearings of jungle will sufhc 
for the more delicate jungle mosquitoes. Surface drainage will reduce th 
numbers of many others. Care in disposal of refuse and the artificia 
storage of water will prevent the multiplication of the more domestic specie^ 
tor some species much can be done by treatment of comparativeb 
small areas by individual effort, but for others larger areas must be treated 
and without combination of many persons in such cases little can be done. 
. ttle known disease carriers the Anophelines have been consider 
with some detail, and so has the commonest filaria bearing mosquito 
Culex fatigans. ^ 
Yellow fever does not now occur in Asia, but the mosquito which b 
capable of carrying it, Stegomyia fasciata, does occur in certain places. I 
has been pointed out that the opening of the Panama Canal may result ir 
the conveyance of this disease from America to Asia. In such a case the 
Malay Peninsula would be one of the first places to receive the disease, am 
tkc condition for its propagation, the presence oi Stegomyia fasciata , exists ir 
Singapore, Penang, Kwala Klang, and a few other places in the Peninsula 
1 ne mam reliance is to be placed on the work done in the extirpation o! 
this mosquito m the Panama Canal by the Americans, but as this may fail, 
early measures should be taken to deal locally with this mosquito, which is 
less wudely distributed and less numerous than in most tropical countries, 
and so may be more easily dealt with.
