Abstract Mosquito-transmitted diseases pose a threat for a great portion of the world population. Chemical insecticides are the main tool for mosquito control. Heavy dependence on chemicals created several problems such as resistance development in many mosquito species, environmental effects, and human health issues. Other tools for mosquito control were developed and used in some parts of the world. Ribonucleic acid interference (RNAi) is a reverse genetic mechanism that was recently introduced as a new tool for pest control. Regarding mosquito, RNAi was used to study gene function and to discover genes that can be used as targets for control purposes. Several delivery methods are used to induce RNAi in mosquito larvae. Some methods such as injection and soaking are used routinely in RNAi research but have no application in the field. Other methods such as nanoparticles and microbes have some characteristics that make them good candidates for field application. In this report, we will focus on delivery methods for RNAi in mosquito larvae and will give examples for each method.

People living in the tropical and subtropical regions of the world face an enormous health burden due to mosquito-borne diseases such as malaria, dengue fever, and filariasis. Historically and today, targeting mosquito vectors with, primarily, insecticide-based control strategies have been a key control strategy against major mosquito-borne diseases. However, the success to date of such approaches is under threat from multiple insecticide resistance mechanisms while vector control (VC) options are still limited. The situation therefore requires the development of innovative control measures against major mosquito-borne diseases. Transinfecting mosquitos with symbiotic bacteria that can compete with targeted pathogens or manipulate host biology to reduce their vectorial capacity are a promising and innovative biological control approach. In this review, we discuss the current state of knowledge about the association between mosquitoes andWolbachia, emphasizing the limitations of different mosquito control strategies and the use of mosquitoes’ commensal microbiota as innovative approaches to control mosquito-borne diseases.

The mosquito-borne arbovirus Zika virus (positive-stranded RNA virus, ZIKV, Flavivirus, Flaviviridae), has caused an outbreak imposing by its extent and quick spread. This became the focus of a current pandemic and public health crisis all around the world because of the incessant geographic growth of both the virus and its mosquito vectors; it is often misdiagnosed with other disease like yellow fever, west nile, dengue and chikungunya because of same clinical manifestation. After unprecedented huge scale outbreak of ZIKV in Pacific, Micronesian island of Yap in 2007, though ZIKV infections are in general sporadic cases or causing mild self-limiting illness, harsh symptoms have been explained including neurological disorders, autoimmune disorder, fetal anomalies, impaired central nervous system of the fetus, microcephaly in newborns, meningoencephalitis, myelitis and Guillain Barre´Syndrome supposed to be linked with ZIKV. The virus is transmitted mainly by a mosquito Aedes aegypti, whereas, other routes of viral broadcast includes monkey bite, coitus and body fluids such as semen, blood and saliva which needs further corroboration. The relationship between these conditions with ZIKV infection is still not established and is under assessment. Till now there is no vaccine or specific antiviral against ZIKV, therefore the public health authority focuses on preventing infection, mainly in pregnant women and virus transmitted area. WHO and other health officials are working on the expansion of new projects and mosquito control techniques to manage up with infection as there is very fewer literature present on the pathogenesis of the ZIKV to help understand the clinical disease spectrum and target treatments to decrease or stop infection. The future status of ZIKV dispersal to other parts of the world is still unknown. The present review emphasizes various features of ZIKV and its history, epidemiology, transmission, clinical manifestations, progress  and advances in developing effective diagnostics, vaccines and drugs/therapeutics along with accepting suitable avoidance and control strategies to undertake this deadly emerging disease.

Chemical Pesticides

One method of prevention of mosquito borne diseases is the reduction of the mosquito population in the various stages of development, such as the use of ovicidal, larvicidal, pupicidal, adulticidal, and mosquitocidal substances. The application of chemical insecticides in mosquito control has resulted in the persistence and accumulation of non-biodegradable chemicals in the ecosystem, biological magnification through the food chain, insecticide resistance, and a toxic effect in human health and non-target organisms. Many studies on plant extracts against the mosquito population have been conducted around the world. The plant-mediated repellents are advantageous over chemical and physical methods, since it is cheap, single-step, and does not require high pressure, energy, temperature, or the use of highly toxic chemicals. In the latest years, a growing number of plant-borne compounds have been proposed for efficient and rapid extracellular synthesis of metal nanoparticles effective against mosquitoes at very low doses. The present study reveals that the aqueous extract of this leaf has a suitable property for a larvicidal natural product and may replace harmful chemical pesticides.

Pragmatist Philosophy

AbstractA pragmatist philosophy of psychological science offers to the direct replication debate concrete recommendations and novel benefits that are not discussed in Zwaan et al. This philosophy guides our work as field experimentalists interested in behavioral measurement. Furthermore, all psychologists can relate to its ultimate aim set out by William James: to study mental processes that provide explanations for why people behave as they do in the world.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.

Abstract Hoerl & McCormack argue that animals cannot represent past situations and subsume animals’ memory-like representations within a model of the world. I suggest calling these memory-like representations as what they are without beating around the bush. I refer to them as event memories and explain how they are different from episodic memory and how they can guide action in animal cognition.

AbstractFe XIV 530.3 nm coronal emission line observations have been used for the estimation of the green solar corona rotation. A homogeneous data set, created from measurements of the world-wide coronagraphic network, has been examined with a help of correlation analysis to reveal the averaged synodic rotation period as a function of latitude and time over the epoch from 1947 to 1991.The values of the synodic rotation period obtained for this epoch for the whole range of latitudes and a latitude band ±30° are 27.52±0.12 days and 26.95±0.21 days, resp. A differential rotation of green solar corona, with local period maxima around ±60° and minimum of the rotation period at the equator, was confirmed. No clear cyclic variation of the rotation has been found for examinated epoch but some monotonic trends for some time intervals are presented.A detailed investigation of the original data and their correlation functions has shown that an existence of sufficiently reliable tracers is not evident for the whole set of examinated data. This should be taken into account in future more precise estimations of the green corona rotation period.
