The following species are listed as being of economic importance : 



Anopheles quadrimaeulatus, the common malaria mosquito, transmits malaria 

 and is a bad pest otherwise. 



Aedes aegypti, the yellow-fever mosquito, transmits yellow fever and dengue 

 fever and is a serious house pest. 



Culex quinquefasciatus, the southern house mosquito, is a serious house pest. 

 It transmits bird malaria and is an intermediate host for some of the filaria. 



Aedes sollicitans, the salt-marsh mosquito, is the most important salt-marsh 

 species generally in the Eastern and Southern States. 



Aedes taeniorliynehus, the small, black salt-marsh mosquito, is another salt- 

 marsh species of economic importance, especially in Florida. 



Psorophora columbiae, the Florida glades mosquito, is an important fresh- 

 water species in southern Florida, and is also troublesome in other areas. 



Mansonia perturbans, the common Mansonia, is a severe pest in areas where 

 suitable breeding conditions occur. 



(Some of these species may also transmit equine encephalomyelitis or other 

 diseases.) 



The woods mosquitoes, taken collectively, form a group that is also* 

 of considerable importance as a pest of man and animals. The prin- 

 cipal ones in the Southeast are Aedes triseriatus, A. infirmatus, A., 

 atlanticus, A. vexans, Psorophora ferox, and P. ciliata. Culex sali- 

 narius and C. restuans are important at times, and various other spe- 

 cies, such as Psorophora cyanescens, A. canadensis, and Mansonia, 

 titillans, may become annoying in restricted localities. 



Of the 47 species taken in Florida, 7 are tropical species, and 6 of 

 these 7 have not been found elsewhere in the United States. Three 

 [Culex corniger, Psorophora pygmaea, and Anopheles albimanus) have, 

 been recorded only once each on the extreme southern keys and appar- 

 ently have not become established in the State. The other four (Wye- 

 omyia vanduzeei, W. mitchellii, Mansonia titillans, and Deinocerites 

 cancer) are fairly common in southern Florida, but have not been 

 found north of about latitude 29°. Ten species are recorded for 

 Georgia, Alabama, and Mississippi which have not yet been found in 

 Florida ; some of these probably will be found there. The Louisiana 

 records contribute two more species, Arkansas two, and North Caro- 

 lina and Tennessee two. The last six species, from the border States, 

 are incursions from the western and northern faunas ; and it is prob- 

 able that further collecting in these States, particularly near their 

 western and northwestern boundaries, will increase the present known 

 number of such incursions. However, in the northeastern part of the 

 region at least, the Virginia records contain only one species {Aedes 

 cantator Coq.) not found in the list. The questionable records for A. 

 nigromaculis and A. dorsalis in Louisiana are discussed in the text. A 

 reported occurrence of Culex coronator Beyer in New Orleans (12) is 

 believed to have been based on a misidentification, and the species is not 

 included in the list. 



LITERATURE ON MOSQUITOES 



The literature on mosquitoes, especially that dealing with bionomics,, 

 methods of control, and disease transmission, has become exceedingly 

 large, and the articles have appeared in widely scattered publications. 

 General reference works covering the mosquitoes of the United States: 

 are, however, comparatively limited. 



Qf the references that include the southeastern species, the large 

 monograph by Howard, Dyar, and Knab {68) contains detailed de-
