THE CONTROL OF MOSQUITOS 
Fred Knab, Science, January 24, 19138 
There are some points in this short article that should be 
very generally known. 
The problem of mosquito control is part of the work of 
disease prevention, as is well known. There are very few com- 
munities now where the relation of these insects to malaria is 
not fairly well understood. There are, however, a number of 
facts which are new to most of us. The old idea of destroying 
the insects was largely based on experiments with one species. 
People must learn that there are numbers of species and some 
of these have different habits. It used to be supposed that all 
adult females hibernated in cold weather and that the eggs were 
deposited and the new generations came on in warmer weather. 
This thought has led to a failure in the control in many cases. 
Oiling and petralizing in warm weather misses many. Most of 
the mosquitos are from larve developed in early spring snow 
water. The best remedy is the removal and the burning in late 
autumn of all plant debris and dead leaves from dried out 
pools. If they cannot be burned they should be stacked on high 
and dry ground. Almost all of the eggs are deposited on dead 
leaves and require only a little moisture to develop.

This article deals chiefly with Amblyomma aganum n. sp., a 
species of tick found upon Bufo, boa constrictor, and other cold 
blooded animals. The adult measures 5.6 mm. by 3.7 mm. when 
in a condition of hunger, and about 17 mm. by 12.6 mm. when 
full of blood. The color is dark brown, with three copper-col- 
ored spots on the seutum. The larve and nymphs show a con-
