Entomological field handbook
Description:Preface -- Introduction -- General facts concerning mosquitoes -- Position of mosquito subfamily in the zoological classification -- Subdivision of mosquito subfamily into tribes, genera and species -- Differentiation of mosquitoes into Anophelines and Culicines -- Identification of Anopheline mosquitoes -- Life history and habit of the United States Anopheline species -- Entomological phases of malaria control -- Entomological field equipment -- Handling of mosquito specimens -- Control measures -- Appendix: the more important malaria vectors of the world.
This is a preliminary draft of the entomological section of a Field Handbook for Malaria Control. It has been prepared by an entomologist with field experience in malaria control, who is now conducting the In-Service Training course. Guidance and suggestions have been freely given by the entomological staff of MCWA headquarters office. It is hoped that by releasing this guide to our field personnel it will be subjected to critical field use and thereby improved through the suggestions and criticisms of its users. All suggestions for its improvement will be welcomed by those who are concerned with the preparation of the future field manual for malaria control.
This manual is assigned to aid MCWA personnel in carrying on the entomological phases of the program by presenting a summarized account of anopheline biology, methods used in handling mosquito specimens in the field and procedures in gathering data for use by the control supervisor. Since successful therapeutic immunological measures for combating malaria have not yet been discovered, control of the mosquito vector must still be considered the most effective means for reducing the human malaria hazard. Intelligent mosquito control work must be based on a knowledge of the varied habits of the specific anopheline responsible for malaria transmission. Therefore, a discussion of the general habits of mosquitoes is supplemented in this manual by more specific information on the habits of the anophelines of the United States. Although all twelve of the United States anophelines are capable of transmitting malaria experimentally, only three have been incriminated by epidemiological evidence as effective carriers of the disease under natural conditions. These are Anophales quadrimaculaturs in the Southeasern States, A. albimanus in the lower Rio Grande Valley of Texas, and A .freeborni in the Western States.
