Summary and Conclusions

Examination of ingested blood by the precipitin reaction has shown that Anopheles pseudopunctipennis captured in the houses of two localities in the Province of Tucumán, Argentina, had fed on various hosts in the following proportions: man, 50 per cent; dog, 21.8 per cent; horse, 8.9 per cent; sheep or goat, 6.2 per cent; cow, 5.5 per cent; chicken, 3.2 per cent; hog, 2.5 per cent; cat 1.8 per cent. Man and dog being essentially house-dwellers at night, the results demonstrate a very high domesticity for the insect.

Ever since the work of Paterson (4) in 1911, it has been recognized that A. pseudopunctipennis is the most dangerous malaria transmitter in Northern Argentina. Our work furnishes additional evidence against this species.
