Opis:
Application of remote sensing and other GIS methods in the subject of mapping mosquito breeding sites has not been premised accordingly. Despite the facts that the duration of field surveys would be shortened and the effectiveness of action plans would be higher with the supportance of computer modelling techniques. This work aimed to evaluate the applicability of digital elevation models and aerial photographs in the prediction of mosquito breeding sites. Relief analysis was carried out seeking depressions based on elevation models created with TIN and kriging interpolation methods. Spectral analysis was performed on aerial photographs to identify the patches of higher water content or moisture. The results show that terrain analysis can not give acceptable results due to its resolution and accuracy. Spectral analysis of normal (visible range) photographs can be a useful tool in predicting of breeding sites. On grasslands the verificitaion revealed 91% correct results.

Opis:
The high prevalence of malaria in Africa has defiled many strategies aimed at its eradication. Researchers from various fields have tried without success in this fight against mosquito and its malaria disease. Annually billions of dollars are spent in the design of programs which are aimed at combating this dreaded disease. However all this spending seems to go down the drain as malaria and its vector mosquitoes celebrate their unflinching victory. Current control measures focusing on ways of preventing the disease vis- a -vis, protect man from the vectors “anopheline mosquito” are the mainstay of malaria prevention and control. Many of these control measures are operational with each contributing in its little way. The use of Long Lasting Insecticide Treated Nets (LLITN) and Indoor Residual Sprays (IRS) are well established strategies with global recognition and currently ongoing in Africa. However, as a result of shortcomings in these major control measures, new strategies with hopes of blissful success are been sought after. Larviciding (abortion of metamorphosis) and constant and adequate environmental sanitation seems to be the next option available for use. This article therefore takes a look at the vector- anopheline mosquito, its ecology, productivity and distribution. It also considers malaria and the various control and preventive measures currently targeted at its eradication.

Opis:
Objectives This study analyzed the effect of the number of mosquito nets that are owned by households, dwelling characteristics and maternal demographic characteristics on malaria infections. Material and Methods The 2011 Demographic and Health Survey (DHS) data for children under 5 years of age were used. The children were subjected to haemoglobin test and rapid diagnostic test (RDT) to ascertain the presence of malaria parasites. Data were analyzed using probit regression method. Results It was found that 2.43% and 8.68% of the children were living in houses that were prone to landslide and flooding, respectively. Also, 19.93%, 17.08% and 16.26% of the children lived in houses without windows, with broken windows, and with a hole in the roof, respectively. Only 5.59% and 23.96% of the children lived in houses with window and door nets, respectively. Mosquito nets were owned by 64.03% of the households, where Adamawa Region had the lowest coverage (52.23%). Reasons for not owning mosquito nets by all the households included: lack of financial means (25.17%), using something else (1.80%) and not having many mosquitoes in the vicinity (5.53%). In the probit regression, variables that significantly reduced malaria infections among the children (p < 0.05) included: the number of mosquito nets, urban residence, improved toilet, ownership of a radio, residence in flood-prone area, mother’s secondary education, mother’s tertiary education and residence in areas with not many mosquitoes, while infections increased along with the household size, residence in areas prone to landslide, severe anaemia, moderate anaemia, mild anaemia and age of the children. Conclusions Ownership of mosquito nets and dwelling characteristics are critical factors influencing infections with malaria. There is a need to ensure compliance with its use since there are disparities between access and actual usage. Also, addressing malaria problem in Cameroon should consider regional disparity in malaria incidence rates and more engagement of the media, among others, for appropriate sensitization.

Opis:
Malaria is a major public health problem in most tropical and subtropical regions, including in our country, Ethiopia. A report published in 2010 stated that more than 1.2 million global malaria deaths due to malaria occurred in the one year alone. This figure includes both children and adults. Malaria disease is transferred from an infected person to an uninfected one by the bite of the female Anopheles mosquito. Herein, Plasmodium falciparum, P. vivax, P. malariae, P. ovale and P. knowlesi are the most important malaria causing parasites. Malaria disease does not have any effective treatment in the form of vaccines or drugs, so vector control is the only possible ways of prevention. Mosquito control using pesticides is presently the most widely used method for disease control. However, insecticide resistance has enabled pest resurgence, and the insecticides themselves have negative effects on human health, the environment and non-target organisms. In order to avoid these problems, biological control methods are proposed to control mosquito vectors. Biological control is an ecologically safe and effective means of minimizing pests and pest damage by means of using natural enemies. This review article offers an over view of the most favorable biological control methods for malaria extermination, such as larvivorous fish, entomopathogenic fungi, bacteria, viruses, nematodes and toxorhynchites larva. Here, we will discuss the current literature regarding biological control agents against the mosquito vector, and in doing so, will bring to light the importance of biological control in countering malaria. Finally, we will discuss the advantages and disadvantages of biological control methods, as compared with other methods commonly used to control malaria.

Opis:
The impacts of fluctuations in weather and climate on malaria prevalence under a future climate change have been an issue of major interest because the disease is a public health problem. Thus, this study investigates the impacts of rainfall on the regional variations of malaria in Ekiti State, Nigeria using 2001-2011 data. The data are for the Central, Eastern, Northern, Western and Southern parts of Ekiti State which are represented by Ado, Ekiti East, Oye, Ekiti South West and Ijero LGAs respectively based on the available data. The results indicate that the total infections over the study period in Ado, Ekiti East, Oye, Ekiti South West and Ijero LGAs are 207033, 67890, 80827, 55986 and 87521 cases respectively. The malaria disease is most rampant among the youths in all the LGAs while the observed cases within the female populations are also slightly higher than the mean infections in the male group. Similarly, an increase in rainfall intensity will lead to corresponding rise in the malaria cases while the spread of the disease seems to also depend on population distribution with the highest seen in the highly populated Ado LGA and among the youths that has the most population in the age groups. However, the disease could be reduced through improved personal hygiene, good drainage system, sleeping under insecticide treated mosquito nets, spraying of insecticides and access to good and affordable medical services. These findings might be used in establishing good immunization system for the vulnerable children and other age groups so as to curb the spread of the disease.

The research is devoted to ethno-semiotic characteristic of an image of a mosquito as a factor of entomological code of the traditional spiritual culture of Belarusian people. It has been shown that in the system of entomological imagery a mosquito is a male erotic symbol, and it correlates with concepts of small, weak, blood, victim, fertility, heat, hedonism, demon. The mosquito correlates with mythological elements: zoological (bird, snake, horse, etc.), dendrological (oak, walnut), demonological (devil), anthropological (saint, nun, tsar, soldier) and other conceptual codes.

Objective: To estimate the prevalence of usage, unsafe practices and risk perception regarding household pesticides in a rural community of Tamil Nadu, India. Materials and Methods: In a cross-sectional survey we used a pre-tested questionnaire and trained interviewers to collect information on household pesticide use for the past 6 months from any adult member of randomly selected households. Results: Out of 143 households, 95% used at least one household pesticide (95% CI: 93.5-99.5) and 94% used at least one household pesticide specifically for mosquito control. The most commonly used pesticides were mosquito coils (75%), mosquito liquid vaporizers (36%), ant-killing powder (24%) and moth/naphthalene balls (18%). The major non-chemical methods of pest control were rat traps (12%) and mosquito bed nets (7.5%). Out of the mosquito coil users, 61% kept the windows and doors closed while the coil was burning. Out of the moth ball users, 88% left them in the place of use till they fully vaporized. Nearly half of the users did not know that household pesticides were harmful to their health and the health of their children. Conclusions: The use of household pesticides was highly prevalent in this rural community. The prevalence of unsafe practices while handling them was also high. We recommend that the users of household pesticides be educated about the health hazards and about safe practices and non-chemical methods of pest control be promoted.

Opis:
Cry4Aa 678 amino acids fragment (60 kDa) was cloned into Escherichia coli. After induction with IPTG the 60 kDa Cry4Aa fragment was purified by Ni chromatography, separated by SDS PAGE and identified by mass spectrometry (MS/MS). The 60 kDa Cry4Aa fragment exhibited high toxicity towards Ae. aegypti larvae. The earlier results [1] show that Pichia pastoris yeast cells expressing tmfA (synthetic gene coding for the Trypsin Modulating Oostatic Factor of Ae. aegypti) together with E. coli cells expressing Bti toxin genes (cry4Aa, cry11Aa, cyt1Aa and p20) are synergistic. Therefore, P. pastoris, which synthesizes high amounts of heterologous proteins was genetically engineered to produce TMOF and Cry4Aa. Codon-optimized synthetic genes, cry4Aa-tmfA, gst-cry4Aa-tmfA, tmfA and gfptmfA that were expressed by P. pastoris and fed to Ae. aegypti larvae caused 90% mortality. GST (glutathione-S-transferase) enhanced the activity of Cry4Aa-TMOF and protected it from heat denaturation and GFP (Green Fluorescent Protein)- TMOF allowed us to follow yeast cells consumption by individual larva using fluorescent microscopy. This report shows for the first time that 60 kDa Cry4Aa and TMOF expressed together in P. pastoris are highly toxic to Ae. aegypti larvae.

Opis:
In recent years several vector-borne, parasitic or zoonotic diseases have (re)-emerged and spread in Europe with major health, ecological, socio-economical and political consequences. The problem of increasing risk of vector-borne diseases in Europe is widely discussed at periodic international conferences like International Jena Symposium on Tick-borne Diseases or the conference organized by European branch of Society for Vector Ecology ESOVE. The problem takes also effect in establishment of international projects (e.g. EDEN, VBORNET). Mosquitoes and ticks are the most remarkable disease vectors transmitting microorganisms (viruses, bacteria, parasitic protozoans) or metazoan parasites (nematodes). In Europe mosquitoes have a strong effect on human life quality, tourism and economic development because of being a nuisance. However, the changing climatic conditions make mosquito-borne diseases which have already been eradicated, or newly appearing diseases, a threat to human health. Among tick-borne diseases in Europe, the most common is Lyme disease and tick-borne encephalitis, but the list of pathogens identified in ticks keeps increasing and it is expected to increase the number of cases of tick-borne infections. Assessment of vector-borne risk is enhanced by very helpful Geographic Information System – a notable technique for comprehensive analysis of both abiotic and biotic data.
