CHAPTER III.
THE ANOPHELINE MOSQUITOS OF SALSETTE.
The following are the species of Anopheline mosquitos which were
found in Salsette during the present enquiry;—
Myzomyia culicifacies.
Myzomyia listoni.
Neocellia stepliensi.
Nyssorhynchus us fuliginosus.
Nyssorhynchus jamesii.
Pyretophorus jeyporiensis.
Nyssomyzomyia rossii.
Nyssomyzomyia punctulata.
Myvorhynchus barbirostris.
It will he noticed that those are the same anophelines as those found
on Bombay Island by Dr. Bentley, with the addition of Py. jeyporiensis and
N. punctulata.
In Appendix I is given a table in which the anophelines are mentioned
one by one, with the exact places where they have been found in the larval or
adult state within the boundaries of the different villages, the latter being
grouped according to the nearest railway stations.
In Appendix II another table gives the villages in alphabetical order,
with the names of the different species, and the places in which they have been
found. From both of those tables the record of N. rossii has been omitted.
It is hoped that this will facilitate any research that may in future be
carried out in order to discover which mosquitos are the actual carriers.
In Appendix III notes are given on the apparatus used in collecting
larvæ, and on the instructions issued to subordinates employed to collect
them.
The first four of the anophelines mentioned have been found, in one
part of India or another, to be carriers of Malaria.
The following table gives the proportion of adults captured and brought
for identification from the East and from the West side of the island respect-
ively, out of a total of 823 from the East side and of 1,168 from the West side.
It will be noticed how closely the two sets of percentages resemble one
another :—

The next table gives the proportion of the samples of larvæ of different
species brought from different parts of the island, out of a total of 522 samples
identified. As many as possible of the bottles of larvae were kept standing in
order to let the adults hatch out, scores of bottles being accordingly stocked
for issue:—

The figures for the larvæ are a much less reliable guide than those for
the adults to the actual extent to which different species infest the island. The
proportion of specimens of N. rossii larvæ found, for example, varies with
the weather very greatly. A few weeks of dry weather is sufficient to cause
their almost complete disappearance, and a single shower of rain to cause
their re-appearance, at some places in every puddle or hoof-print.
It was unfortunate for the enquiry that the monsoon stopped unusally
early, at the very beginning of September, as this made it impossible to
conduct a really representative examination of the larvæ of the rice-fields.
WELLS.—The larvæ of six species, three of which, My. culicifacies,
My. listoni and Ny. futiginosus, are known carriers of Malaria in one part
of India or another, were found in wells. The number .of wells actually
examined was not recorded, but, roughly speaking, two wells out of every
three were found to contain the larvae of one or more anophelines. Leaving
out of consideration the wells in which the larvae of N. rossii were found,
and counting a well as one, two or three according to the number of species
found in it, the following figures were obtained :—

BOBROWTITS.—The borrowpits of the B. B. & C. I. Railway also
deserve special mention, as they continue to breed mosquitos very late in the season,
and long after most other temporary breeding-places have dried. Moreover,
there is a chain of them running through the most malarious part of the country
through which the line runs. A special re-examination of them was undertaken
late in October, there having been practically no rain since the beginning of
September. Larvæ were brought on this occasion from 55 borrowpits.
Excluding 9 of them, in which only the larvae of N. rossii were found, the
proportion in which those of different anophelines were found was as follows :—

of only 5.2 per cent. Their children are not exposed in the way the others
are in the Malaria season, and they have every advantage that good housing
and good feeding can give ; more typical little banias and banianis could
hardly be seen. The sudden change which a short distance from the hills
makes may be seen by comparing the Spleen Rate of Kirol, where the people
mostly work in the rice and grass-lands at the foot of the hills, with that of Old
Kurla, down by the head of the Bándra Creek. .
It will be seen how free from Malaria are places right away from
the hills, such as New Kurla, Kolhekalyan, Vakola (close to Santa Crujs
Cantonment), Santa Cruz and Vila Parla.
In attempting to account for that relationship of Malaria to
Physiography which is so unmistakeably brought out by the Spleen Census, it is
impossible at present to do anything more than surmise that it is the dampness
of the ground associated with the constant movement of underground water
from, the hills towards the sea, and the shelter from the wind provided by
the rank growth, of trees and grass on the soil formed by the disintegration
of the trap, that enable the anophelines to survive so well after the breeding-
season, and to persist in numbers long enough into the dry season to become
infected, to develop the parasite, and thus to start the cycle of infection of the
mosquito by man and of man by the mosquito.

The larvae of not more than one tank, well or stream may be put into one bottle,
though a chain or rice-fields or borrow-pits may be considered as one. When enough
larvæ have been secured the cap is to be fixed on with the elastic, and the bottle given
back to the cooly. The number of the bottle, and a short description of the piece of water
from which the larvæ were taken, with the name of the village, and if possible the
survey number, should be entered in the note-book, before the cooly replaces the bottle in
its compartment of the box.
