MALARIA 
2 . Anopheles (Stethomyia) kompi 
Edwards 1930 
There are no data of infections of A. 
kompi with malarial plasmodia. The rela¬ 
tive infrequency of A. kompi in Panama 
suggests that it is not an important vector 
there. Additional studies will be required 
to determine its possible relation to malaria. 
3. Anopheles (Anopheles) eiseni 
Coquillet 1908 
a. Experimental infection. — P. vivax. 
According to Coveil (1927), Davis (1926) 
failed to demonstrate infection in four 
mosquitoes which had fed on a P. vivax 
gametocyte carrier. In Panama, Simmons 
(1936d) found a single oocyst containing 
sporozoites on the stomach of a specimen 
of A. eiseni which had fed on a carrier of 
P. vivax gametocytes. There are no data 
relative to its infection with P. falciparum 
and P. malariae. 
b. Infection in nature. No data. 
c. Epidemiological. Data inadequate. 
Additional studies will be required to 
determine the possible susceptibility of A. 
eiseni to malaria and its importance as a 
vector. 
4. Anopheles (Anopheles) hectoris 
Giaquinto Mira 1931 
a. Experimental infection. — P. vivax. 
De Leon (1933) reported the infection of 
1 to 5 mosquitoes, with the formation of 
oocysts. 
P. falciparum. De Leon (1933) also dis¬ 
sected 41 mosquitoes fed on P. falciparum 
and found oocysts in 3. P. malariae. No 
data. 
b. Infection in nature. No data available. 
c. Epidemiological. According to Gia¬ 
quinto Mira (1936), A. hectoris must be 
dangerous in its restricted area of distri¬ 
bution, for'it is the only species found in 
a place where an epidemic of malaria 
occurred, and it has been infected experi¬ 
mentally. 
The evidence indicates that A. hectoris 
is a potential vector of malaria, but addi¬ 
tional studies will be required to determine 
its importance in this respect. 
5. Anopheles (Anopheles) parapunc- 
tipennis Martini 1932 
This is a rare highland species found in 
Mexico and Central America. The data of 
its relation to malaria are inadequate 
(Komp 1940b). 
6 . Anopheles (Anopheles) pseudo- 
punctipennis Theobald 1901 
a. Experimental infection. — P. vivax. 
Darling (1910) in Panama failed to find 
infection in 4 mosquitoes. Barber, Komp 
and Hayne (1927), in New Mexico, re¬ 
ported the experimental infection of 1 of 
12 mosquitoes, and Shannon and Davis 
(1930), in Argentina, reported negative re¬ 
sults with 6 mosquitoes. Simmons (1939b) 
fed 6 mosquitoes on a tertian patient with 
an undetermined gametocyte density and 
found 1 infected. 
P. falciparum. Darling (1910), in Pan¬ 
ama, found 4 of 27 mosquitoes infected; 
Shannon and Davis (1930), in Argentina, 
reported the infection of 3 of 8 mosquitoes 
which had fed on patients treated with 
quinine. Simmons (1939b), in Panama, 
during 1935-36 fed 84 A. pseudopuncti- 
pennis on carriers and found 7 to be in¬ 
fected. Forty-nine of the latter fed on 
patients with low gametocyte densities 
(0.4 to 3 per 100 leukocytes), and the 
others on patients with densities from 2.8 
to 12. Earle (1936b), in Granada, reported 
the infection of 4 of 21 mosquitoes. 
Boyd and Earle (1939), comparing the 
susceptibility of a Mexican strain of A. 
pseudopunctipennis to infection with 
strains of P. falciparum from Mexico and 
Florida, reported the infection of 7.1 per 
cent of 28 mosquitoes with the Florida 
parasite and 4.1 per cent of 24 mosquitoes 
with the Mexican parasite. In these ex¬ 
periments the susceptibility of insectary- 
raised imagines of A. pseudopunctipennis 
from the Mexican highlands to Mexican 
and Floridan strains of P. falciparum was 
not significantly different, and it was dis¬ 
tinctly lower than that of A. quadrimacu- 
latus controls. 
P. malariae. A few negative attempts to 
infect this mosquito with P. malariae have
