What is entomological surveillance?

What is entomological surveillance?

Entomological surveillance focusses specifically on collecting data on arthropods as vectors of human diseases and is subject to general principles of public health surveillance [15].

What is entomological risk?

Entomological Risk Score = Hazard Severity ´ Hazard Probability . We performed deterministic calculations to determine whether small increases in probability could result in discontinuous jumps in risk and to assess whether an entomological risk score could encompass more than one risk category.

Who is Aedes?

Who spreads dengue and severe dengue? Dengue is spread through the bite of the female mosquito (Aedes aegypti). The mosquito becomes infected when it takes the blood of a person infected with the virus. After about one week, the mosquito can then transmit the virus while biting a healthy person.

What is ovitrap index?

The use of traps for oviposition (ovitraps) is a method of collecting eggs that provides an evaluation of the density of A. aegypti, because they attract gravid females for oviposition, also making it possible to eliminate eggs from the environment.

What is the study of insects and bugs called?

Entomology is the study of insects and their relationship to humans, the environment, and other organisms. Entomologists make great contributions to such diverse fields as agriculture, chemistry, biology, human/animal health, molecular science, criminology, and forensics.

What is vector borne?

Vector-borne diseases are infections transmitted by the bite of infected arthropod species, such as mosquitoes, ticks, triatomine bugs, sandflies, and blackflies. Arthropod vectors are cold-blooded (ectothermic) and thus especially sensitive to climatic factors.

What is 4S strategy against dengue?

The 4S campaign stands for “Search and Destroy” mosquito breeding places, “Secure Self Protection” from mosquito bite, “Seek Early Consultation” when signs and symptoms of dengue occur, and “Say Yes to Fogging” as a last resort when there is an impending outbreak.

What is the purpose of ovitrap?

The purpose of an ovitrap is to measure the distribution of Aedes aegypti mosquitoes in terms of time and space. It helps to detect the presence or absence of Aedes aegypti mosquitoes.

How does an ovitrap work?

An ovitrap is a device which consists of a dark container containing water and a substrate where mosquitoes can lay their eggs. The eggs then fall through the mesh into the water, where the larvae hatch and develop into pupas.

What are entomological techniques?

Entomological techniques include rearing, colony establishment, behavior assays, growth analysis, and insecticide dose/response bioassays.

What is the study of ants called?

Her specialty is myrmecology—the study of ants.

What is the meaning of entomological?

1. entomological – of or relating to the biological science of entomology; “entomological research”

How often should an entomological survey be carried out?

Frequency of entomological surveys It is recommended that entomological surveys are carried out at least in two sentinel sites per month by the entomological teams attached to Regional Malaria Offices of the Anti Malaria Campaign.

What does an entomological team consist of?

An entomological team consists of two Entomological Assistants, one Public Health Field Officer, five Spray Machine Operators or labourers and a driver and they are under direct supervision of Entomologist (AMC HQ)/ Regional Malaria Officer (AMC). Work plans for sentinel site monitoring and spot checks are shown in table 1 and 2. 5 Table 1.

What do you study in entomology?

Entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology, and paleontology .
