영문목차

The eradication of malaria is a global issue requiring professionals to fully understand the ecology of the disease vectors. The authors of this unique report have 40 years' experience across 5 continents and have produced a comprehensive overview of the biology, behaviour, and impact of mosquitoes.

The 19 chapters extent from an introduction to insects and mosquito systematics through to the development of novel control techniques and incorporate case histories of the vectors and their relationship to malaria in a variety of settings.

  • Figure 91: Sensitivity of R0 to changes in mosquito density, biting rate, and mosquito survival calculated for the Ross-Macdonald model (based on Koella 1991). Macdonald's formula for R0 is: where the different parameters are m = the number of female mosquitoes per human host, a = the number of bites per mosquito per day, b = the probability of transmitting infection from an infectious mosquito to a human (per bite), c = the probability of transmission of infection from an infectious human to a mosquito (per bite), ? = the rate of recovery of humans from infectiousness, p = the daily survival of adult mosquitoes, and ? = the duration of the extrinsic cycle (the time required for the development of sporozoites from infection of the mosquito). Changes in parameter values are represented as the efficacy of shown factors relating to the original setting (e.g., an efficacy of 50% corresponds to a multiplication of m, or 1/? by 0.5; m or 1/? for the basic reproductive number linearly); therefore, this efficacy corresponds to a 50% decrease in reproductive number. Biting rate, a, enters the reproductive number quadratically, so that an efficacy of 50% in reducing this leads to reduction in R0 to 0.52 = 0.25 times its original value. Efficacy in adulticiding of 50% corresponds to a 50% reduction in survival per unit time. This enters the formula for R0 as a power function so decreases in this lead to the largest changes in R0.
