195. Cotton square-weevil (Anthonomus vestitus) and its parasites. 



About 12 species of hymenopterous parasites are at work, one in very large num- 

 bers compared with the others in the coast region of Peru, but they kill only about 

 18 per cent, of the host. Ants of the genus Solenopsis, very close to S, geminata, are 

 present but do not seem to prey upon the weevil. The weevil requires marked atmos- 

 pheric humidity to insure activity. It is known to exist in the cotton districts from 

 Guayaquil south to Tambo de Mora near Pisco, in the lower coast region, but has 

 not yet been found in the foothill cotton districts nor in the montana.
