Workshop no. 7. Digestion in haematophagous arthropods

Published online by Cambridge University Press:  19 November 2018

Extract

In vector-borne diseases it is generally the vector which determines the success of disease transmission and efforts to limit the incidence of such diseases generally involve control of the vector. The very nature of their feeding habits renders haematophagous arthropods prime candidates for disease transmission and a great deal is now known of the biology of the most important vectors. Nevertheless, there are many areas in which our knowledge is incomplete or about which conflieting views exist.
