Vector Control

Sadegh Vaez‐Zadeh · 2018

Abstract The chapter begins with a description of the scalar control of PMS motors. The fundamentals of PMS motor vector control (VC) are then presented with an eye on the analogy with DC motor operating principles. The VC of surface-mounted permanent magnet pole motors and interior permanent magnet (IPM) motors are presented in various reference frames. Current and voltage operating limits are incorporated into the control systems. Flux control modes of operation of PMS motors together with the corresponding control means in different reference frames are also presented in detail, as a particular feature of this book. These include maximum torque per ampere (MTPA) control, maximum torque per voltage control, and unity power factor control. Finally, loss minimization control by offline and online strategies is elaborated after presenting the method of motors loss reduction and the PMS motor loss modeling.

VECTOR CONTROL ASPECTS

Stead, Frank M., Peters, Richard F. · PubMed Central · 1953

The emergency vector control measures used during the summer of 1952 were designed to supplement the normal mosquito control programs of mosquito abatement districts. The emergency measures were aimed at destruction of adult vector mosquitoes in populated areas as contrasted to normal programs which consist of elimination of breeding places or destruction of the aquatic stages of mosquitoes. Experience during 1952 clearly demonstrated the limitations of present techniques for coping with adult mosquitoes and pointed up the need for better understanding of the factors controlling survival of Culex tarsalis over the winter months, as well as the need for better methods of measuring the prospect of a large number of infected vector mosquitoes early enough in the year to permit the establishment of preventive rather than palliative measures.

Modern Vector Control

Neil F. Lobo, Nicole L. Achee, John Greico et al. · Cold Spring Harbor Perspectives in Medicine · 2017

The rapid spread of mosquito resistance to currently available insecticides, and the current lack of an efficacious malaria vaccine are among many challenges that affect large-scale efforts for malaria control. As goals of malaria elimination and eradication are put forth, new vector-control paradigms and tools and/or further optimization of current vector-control products are required to meet public health demands. Vector control remains the most effective measure to prevent malaria transmission and present gains against malaria mortality and morbidity may be maintained as long as vector-intervention strategies are sustained and adapted to underlying vector-related transmission dynamics. The following provides a brief overview of vector-control strategies and tools either in use or under development and evaluation that are intended to exploit key entomological parameters toward driving down transmission.

Malaria vector control

Background: Since 2011, the NMCP of Benin has implemented a large IRS campaign using bendiocarb in the department of Atacora in Bénin. The aim of this study was to evaluate the susceptibility of An. gambiae mosquitoes to bendiocarb, before (2010) and after (2012) the implementation of IRS interventions and to report the evolution of Ace-1R mutation frequency in this region. Methods & Materials: Mosquitoes resting in the house (indoor collection) were collected through Morning Spray Catch (MSC) from 7 a.m. to 9 a.m in five treated districts (Kouandé, Natitingou, Matéri, Péhunco, Tanguiéta) and in the Control (Copargo, an untreated district) before and after IRS. Anopheles larvae were also reared in each district before and after IRS and emerging adults were exposed to WHO impregnated papersdiscriminating dosages with bendiocarb, 0.1%. PCR assays were run to determine the members of the An. gambiae complex, as well as phenotypes for insensitive acetylcholinesterase (AChE1) due to Ace-1R mutation. Results: This study showed that the mean Ace-1 mutation frequency have significantly increased from 2010 to 2012 after two years of IRS campaign. Mortality data indicated that mosquitoes were susceptible in 2010 to bendiocarb 0.1%. From 2010 to 2012, after two years of IRS campaign, there is a drastic decline in the An. gambiae susceptibility to bendiocarb in treated districts. The Ace-1R mutation was found in An. gambiae s.s. and An. coluzzi with frequency of7.33% and 7.35%.The high proportion of homozygous susceptible specimens survived from the WHO bioassays may suggest the implication of the other mechanisms of resistance such as biochemical resistance mechanisms. Conclusion: These results are of prime importance in the effort to document multiple impacts of operational control program on mosquito vectors. It showed a significant increase of Ace-1 allele frequency and resistance to bendiocarb in Anophele gambiae population after IRS implementation that can be a threat for malaria vector control based on the IRS which is in progress in Benin.
