Abstract

Most widely affecting species include Culex quinquefasciatus, A. albopictus and A. aegypti which serve as vectors for many hematophagous diseases. Various control measures have been used to control the mosquitoes but most important is the use of synthetic insecticides. This research focused on the use of botanical extracts and green synthesized silver nanoparticles of four different plants i.e. Moringa Olifera, Zingiber officinale, Syzygium aromaticum and Datura stramonium. Percent mean mortality was calculated. The results of the study indicated that on maximum concentration and all-out exposure time (96 hours) of application of plant extracts and green synthesized silver nanoparticles on mosquitoes Moringa Olifera based plant extract give highest percent mortality that was 79% and Silver nanoparticles of that plant also give highest percent mortality that was 92%.

Highlights

  • Due to the diversity of their forms and habitats, insects have seriously affected humans for a long time

  • Mosquito populations and the spread of mosquitoborne pathogens are sensitive to temperature and hydrological variability [11]

  • Order to combat these problems, scientists are looking for alternatives from natural resources to control the mosquitoes

Summary

Introduction

Due to the diversity of their forms and habitats, insects have seriously affected humans for a long time. Mosquitoes play an important role, and the most widely affected species include Culex quinquefasciatus, A. albopictus, and A. aegypti, which are many blood-thirsty diseases Media [10]. Mosquito populations and the spread of mosquitoborne pathogens are sensitive to temperature and hydrological variability [11]. The concentration of greenhouse gases in the atmosphere continues to increase. (In Scientific Basis 2001, higher temperatures and changes in the hydrological cycle are expected to affect mosquito population dynamics and the spread of mosquito-borne diseases. High temperatures may create many controversies about how vector-borne diseases are transmitted [13,14]. Future hydrological changes may determine transmission rates more importantly than global warming. IN order to combat these problems, scientists are looking for alternatives from natural resources to control the mosquitoes
