Kajian Entomologi dalam Mendukung Pengendalian Malaria melalui Program Flying Health Care (FHC) di Kabupaten Yahukimo, Provinsi Papua

Flying Health Care is one of the programs of the Ministry of Health to accelerate the elimination of malaria in an integrated manner, especially in the Yahukimo Regency. The purpose of this activity is to describe the role of entomological aspects in malaria control efforts. The data includes cases of malaria, mosquitoes and Anopheles larvae, breeding place, and vector control efforts. Data was collected by observation, survey, and secondary data analysis. The results of the study show that malaria cases rank first out of 10 diseases in health facilities. Malaria cases were more common occurred at the age of 10-19 years, male and near to health facilities. Breeding places in the form of swamps and puddles in the environment around patients with water depths ranging from 5-30 cm. There is no entomological data at the district level or at Puskesmas Aplim. Ongoing vector control efforts are in the form of distributing insecticide-treated mosquito nets. Insecticide mosquito nets have not been fully distributed to the community, this is constrained by the existing infrastructure in health care facilities. Vector control efforts should be supported by the results of entomological surveys and it is important to do socialization on how to use and maintain mosquito nets at the time of mosquito net distribution.

Knowledge and Practices about Malaria in Two Tribal Dominated Regions of Madhya Pradesh, India

Given the substantial contribution tribal population makes to the overall malaria load in the country, their role is important in the malaria elimination context. Assimilation of correct malaria preventive and care seeking behaviour among them, thereby, becomes very critical. Community level knowledge and practices regarding malaria can reflect on the extent of this assimilation. A cross-sectional survey of 482 randomly selected households was conducted in Umaria and Dindori districts of Madhya Pradesh using a semi-structured schedule to assess the community level knowledge and practices with respect to the causation, transmission, prevention and treatment of malaria. Descriptive statistics are used to determine relative frequencies and percentages. Chi-square test is used to determine the associations between the variables. Majority of the respondents (71.2%) were aware of the role of mosquitoes in the transmission of malaria. However, only 30% of the respondents reported the most characteristics symptoms of malaria, i.e., “fever with chills”. The awareness about transmission and symptoms was associated with educational status of the respondents as well as history of malaria infection. 65% of the households were using mosquito net bed and 57% burnt foliage/cow dung cakes to protect themselves from mosquitoes. Out of all the malarial cases, 61% sought treatment from government health facilities, while remaining from private facilities. Findings indicate that tribal groups generally possessed knowledge about malaria and engage in desirable behaviours for its management and control pointing towards their acceptance and assimilation of the government programme.

Rural–urban dimensions of the perception of malaria severity and practice of malaria preventive measures: insight from the 2018 Nigeria Demographic and Health Survey

Morbidities and mortalities caused by malaria are still a serious issue in Nigeria, with the country accounting for 25% of malaria morbidities and 24% of malaria mortalities globally in 2018. Treated bed nets reduce the incidence of malaria, but not all Nigerians use them. This study aimed to examine the factors associated with treated bed net usage, including perceived severity of malaria, and the rural–urban differences in the relationship between socio-demographic factors and use of treated bed nets in Nigeria. The analytic sample size comprised 40,693 women aged 15–49 years. Poisson regression and bivariable and multivariable analyses were used to test the study hypothesis that women who agreed that malaria could potentially lead to death would be more likely to adopt malaria preventive measures, including treated bed net use. About 48% of the women slept under a treated mosquito net the night before the survey. Those who perceived that malaria could lead to death had a higher likelihood of using a treated bed net in the urban, rural and combined samples. However, in the multivariable model, the association between perceived malaria severity and use of a treated bed net was only significant for rural women (APR=0.964, 95% CI: 0.933, 0.996). The results unexpectedly suggest that rural Nigerian women who perceive malaria to be severe have a lower likelihood of using treated bed nets. Also, rural–urban variations in the relationship between the socio-demographic variables and use of treated bed nets were observed. Policies should consider the observed rural–urban dichotomy in the influence of perceived severity of malaria and other socio-demographic factors on women’s use of treated bed nets in Nigeria.

Knowledge, perceptions and prevention of malaria among women in Sistan va Baluchestan, Islamic Republic of Iran

A questionnaire about malaria knowledge, beliefs and practices was given to a random sample of 2168 married women from rural and urban areas of Sistan va Baluchestan, Islamic Republic of Iran. The mean knowledge score of subjects was low at 5.5 [maximum 15.0]. Few respondents [37.6%] knew that malaria was an important disease in the area and only 58.4% knew that malaria was transmitted by mosquitoes. Most subjects [69.4%] never used a mosquito net. Only 49.9% of rural and 73.8% of urban residents would seek care for fever and chills from the local health centre. Community health workers [behvarz] were the main source of information [29.5%] for rural women; the role of physicians in education was minimal. Subsequent health education must be tailored to the educational needs of the target population in this area

Behavior of the Use of Mosquito Net as a Prevention of Malaria in Ondorea Village, Nanga Panda Sub-district

Background: Malaria is an infectious disease that is still a world public health problem, especially in developing countries with tropical climates, including Indonesia. Ondorea Village in Nangapanda Subdistrict, Ende Regency, is one of the villages in East Nusa Tenggara, which is a province with APIs above the national average. Objective: To determine family behavior in using mosquito nets as an effort to prevent malaria in Ondorea Village, Nangapanda District. Method: This research is a survey research type with descriptive research design, the design used is"cross sectional".The population were all families residing in Ondorea Village, totaling 178 families, the sample in this study used a total sample. The variable in this study was a single variable, namely family behavior in the use of mosquito nets. The data used in this study are primary data collected by making home visits. Results: Public knowledge about the use of mosquito nets as an effort to prevent malaria in Ondorea Village, Nangapanda District was in the sufficient category, namely 85.39%, those with good knowledge of 6.34% and those with moderate knowledge of 7.87%. The public attitude about the use of mosquito nets is in the good category, namely 99.4%, which has a sufficient attitude of 0.56%. Conclusion: There is no relationship between the level of knowledge and the behavior of using mosquito nets, but it is found that there is a relationship between family attitudes and the behavior of using mosquito nets as an effort to prevent malaria

Dynamics And Impact Of Flowering Insects On Sesamum Indicum L. (Pedaliaceae) Production In Maroua (Far-North, Cameroon)

The study of the variability of the flower visiting entomofauna between Palar and Djarengol-Kodek (Maroua, Cameroon) and the influence of the pollination type were carried out in 2020 for assessing their impact on sesame production. Three treatments of 50 plants each were used according to whether the flowers were open-pollinated (TA) or protected using mosquito net cages (TB) and plastic cages (TC) for analysis. The diversity and composition of the entomofauna were compared between localities from TA as well as the resulting pod and seed yields of the crop. 21 and 12 insect species were found foraging on sesame flowers in Palar and Djarengol-Kodek respectively. Hymenoptera had a high relative abundance ˃ 92% at both sites and played a key role in pollinating the flowers of the host plant species. The diversity index was higher in Palar (H’ = 3.10) than in Djarengol-Kodek (H’ = 2.64). The Jaccard similarity index between both sites was J = 0.43. During their floral activity, these bees promoted autogamy, geitonogamy and xenogamy on S. indicum flowers. The impact of the floral activity of bees on sesame pod and seed yields was in the range of 17.92% - 29.27% and 12.97% - 18.39% in Djarengol-Kodek and Palar respectively with a significant difference between these values (X2 = 156.20; df = 1; P ˂ 0.001 and X2 = 69.74; df = 1; P ˂ 0.001). These differences showed the important role of the variability of the composition and the relative abundance of pollinators on sesame production between sites. Moreover, bee pollination (TA) highly increased anemophily (TB) and cleistogamy (TC) in sesame. Encourage producers to adopt more environmental friendly management methods to help preserve the habitat of sesame pollinator species for better productivity is an important practice.

Measures of The Direct Impact of Hematophagous Flies On Feeder Cattle: An Unexpectedly High Potential Economic Impact

Beside blood pathogens transmission, insects of the order Diptera affect livestock by visual and contact harassment; blood-feeders are responsible of painful bites and blood despoliation, generating behavioural modifications, anaemia and production losses. Knowledge of their economic impact is a basis for cost-effective control. Here, we measured the global impact of Diptera by comparing two batches of six feeder cattle, one in open air, the other protected by a mosquito net. Analytical data were: insect density in open air, and, for feeder cattle: tail-flick counts, hematocrit values (Ht), feed intake, feed conversion ratio (FCR) and live body weight gains (LBWG). Over a period of five months, results showed significant losses of LBWG of cattle exposed to insects, estimated at 8.0±1.5 Kg/month [2.7;13.3], with a total loss reaching 40.0±5.5 Kg/head. Main diurnal insects were Stomoxys spp. and M. crassirostris. There was a strong correlation between fly density and diurnal tail-flicks. Night trapping and tail-flicks showed a potentially important role of mosquitoes to be further explored. Ht of exposed animals was 3-4% lower than controls. FCRs indicated that exposed animals needed 33% more dry matter intake/Kg of LBWG. Economic assessment showed that dipterans were responsible of 10-11% loss of LBWG during the main growing period of feeder-cattle (10-15 months). A feedlot of 100 calves would register a total loss of 16,000$ within 5 months, which appears to be an unexpectedly huge loss caused by dipterans. Investing part of this money in fly control would probably be beneficial.

Mosquito Bed Net Preferences and Efficacy in the Prevention of Gestational Malaria in Yaounde, Cameroon

Malaria prevention methods are diverse. Their availability sometimes does not guarantee effective usage and the use of each method in isolation may not provide the necessary results for the fight against malaria. Pregnant women are relatively more vulnerable and so it is recommended that they should be protected against malaria. Proper protection will require the use of long lasting insecticide treated mosquito bed nets as major malaria prevention method. This study was designed to find out malaria prevalence and factors influencing the use of mosquito bet nets among pregnant women of Biyem-Assi Health District. Information on the knowledge of malaria and use of malaria prevention methods, especially bed nets was collected from 302 pregnant women attending prenatal clinics in health institutions within the Biyem-Assi Health District of Yaounde VI subdivision using a pretested questionnaire. Thick smear was prepared for screening Plasmodium parasites. Analysis was done using EPI INFO version 16 (Chicago IL USA) and test of Chi 2. The study revealed that malaria prevalence was 48.5%. The shape of mosquito net had a significant (P = 0.05) effect on its use and a reduction on prevalence of malaria. The use of mosquito bed net was 47.7% while some of the women (52.3%) did not use it. Profession significantly influenced (P ˂ 0.04) the use of mosquito bed nets. Some of the women did not use mosquito bed nets for different reasons such as heat, forgetfulness, neglect, dislike, etc. The shape and color influenced the use, but this was not significant. Use of mosquito bed nets as major malaria prevention methods is not considered as priority by pregnant women. Sensitization campaigns by government and NGOs should reduce malaria prevalence during pregnancy and give a priority position to mosquito bed nets.

Lack of Evidence for Transmission of Verticillium dahliae by the Olive Bark Beetle Phloeotribus scarabaeoides in Olive Trees

Verticillium wilt of olive, caused by Verticillium dahliae Kleb., is one of the most important diseases affecting olive crops in the Mediterranean area. With the aim to evaluate the role of Phloeotribus scarabaeoides (Bernard) (olive bark beetle) as a dispersal vector of V. dahliae, several experiments were conducted in semi-controlled conditions from May 2009 to April 2012. Groups of olive trees (2.5-year-old) certified free from V. dahliae were covered by a mosquito net and exposed to adults of P. scarabaeoides by three different ways: (1) branches or trunks collected in several olive orchards from trees severely affected by Verticillium wilt and showing apparent entry holes (mating galleries) of P. scarabaeoides; (2) adults of olive bark beetle extracted from damaged branches collected in the field; (3) adults from damaged branches that were superficially inoculated with V. dahliae. The fungus V. dahliae was not detected either by microbiological and molecular techniques from shoots of olive trees with galleries of the insect or from any of the tissues of the collected beetle adults from the galleries. Additionally, Verticillium wilt disease symptoms were not observed in olive trees exposed to the olive bark beetles. Moreover, the pathogen was never detected from any beetle adults that were recovered from the mating galleries of branches or trunks collected in several olive orchards from trees severely affected by Verticillium wilt. We conclude that P. scarabaeoides is not a vector of V. dahliae under the investigated experimental conditions.

Perceptions and practices on malaria in a rural population of Koraput district, Odisha

Background: Malaria is a mosquito-borne disease caused by a protozoan parasite i.e. Plasmodium parasites. It is one of the most prevalent disorders worldwide. India ranked the fourth-highest number of death cases. In Odisha, more than two-thirds of malaria cases are reported from ten southern districts. A high risk of malaria infection is found in Koraput district of Odisha. The present study aims to access the knowledge, attitude, and practices (KAP) about malaria among the individuals of Koraput district, Odisha.Methods: This is a cross-sectional study and 258 respondents were taken randomly from five villages of Koraput district. Data on demographics as well as knowledge, attitude, and practices about malaria was collected by using self-modified and pretested schedules.Results: A significant number of the respondent (97.29%) have reported that they had heard about malaria. 37.60% of respondents answered that they knew it from television, followed by health workers (23.26%) and friends (20.54%). The majority (98.06%) of the sample reported that it is caused by mosquito bites. Almost 63% of the respondents were consulted with a doctor whereas 24.81% consulted first to traditional healers of that region. The majority (99.22%) has a mosquito net and 98.83% of them were used it after a proper wash.Conclusions: Although the study found good knowledge on malaria, still further awareness is required to elevate the present status. In this study most of the respondents had a good level of knowledge about malaria, however, attitude and practices about malaria prevention still need to be improved.
