RIBgIRO, H. & RAMOS, H. Cunha -- <str<strong>on</strong>g>Research</str<strong>on</strong>g> <strong>on</strong> <strong>the</strong> <strong>mosquitoes</strong> <strong>of</strong> <strong>Angola</strong> -- X<br />
females caught inside human habitati<strong>on</strong> (113/237--0.40) is near to<br />
that already found in Lobito (about 0.30) and Luanda (0.37), suggest-<br />
ing that this may be an expressi<strong>on</strong> <strong>of</strong> some real bioecological cha-<br />
racteristic <strong>of</strong> this form.<br />
160 out <strong>of</strong> <strong>the</strong> 350 indoor caught females were ei<strong>the</strong>r freshly fed<br />
or gravid, 58 o<strong>the</strong>r females were unfed and <strong>the</strong> remaining 19 were<br />
biting man (collectors or residents) at <strong>the</strong> time <strong>of</strong> <strong>the</strong> catch. All gravid<br />
females, so, were found inside human habitati<strong>on</strong>. Both males and<br />
females could be found indoors at any time, <strong>the</strong>se <strong>on</strong>es ei<strong>the</strong>r resting<br />
or biting, though <strong>the</strong>re seems to be an evening and a morning peak (34)<br />
for <strong>the</strong> indoor density <strong>of</strong> quinque/asciatus. The main indoor resting<br />
sites <strong>of</strong> this form were <strong>the</strong> bed mosquito-nets (when <strong>the</strong>y existed) and<br />
*.he walls (<strong>of</strong> any material), though <strong>the</strong> ceilings (also <strong>of</strong> any kind),<br />
clo<strong>the</strong>s, <strong>the</strong> underside <strong>of</strong> beds, furniture, etc., were also <strong>of</strong>ten used.<br />
The present remarks <strong>on</strong> C. p. quinque/asciatus, c<strong>on</strong>firming <strong>the</strong><br />
close associati<strong>on</strong> to man <strong>of</strong> this mosquito, a true house-pest wherever<br />
it occurs in <strong>Angola</strong>, also show <strong>the</strong> high degree <strong>of</strong> distinctiveness<br />
between this form and piplens s. str. in that c<strong>on</strong>cerns behaviour and<br />
ecological niches. Here again, as <strong>on</strong> <strong>the</strong> morphological and distributi<strong>on</strong>al<br />
grounds, <strong>the</strong> available evidence is clearly in accordance with<br />
a specific treatment <strong>of</strong> each <strong>of</strong> <strong>the</strong> two forms <strong>of</strong> <strong>the</strong> C. pipiens<br />
complex known to occur in <strong>Angola</strong>.<br />
7.5.20--Culex (Culex) poicilipes (Theobald, 1903)<br />
The first records <strong>of</strong> C. poicilipes in <strong>Angola</strong> are those by Giles (2)<br />
from Benguela (as taeniorhynchoides) and by Wellman (3) (4), from<br />
Biff and Bailundo. Later, it was found at Capel<strong>on</strong>go, Cuchi, Luanda,<br />
Mavinga, and Mul<strong>on</strong>do by Gfindara (10) (ll), at Caxito, Huambo and<br />
N'Giva by Worth & Paters<strong>on</strong> (12) and at Lobito by <strong>on</strong>e <strong>of</strong> us (34).<br />
