Geranium is usually available throughout the world. But it is grown in all the temperate regions of the world; and the mountains of the tropics, mainly in the Mediterranean region. The leaves of this plant are in the shape of a long circle, more like an oval. And, the flowers have a very beautiful appearance. There is one very important quality of geranium that it can grow in any type of soil. No matter how porous or clay-like the soil is; the only condition is that it should not be waterlogged.

A test was conducted to find out the efficacy of different essential oils against flies and geranium was one out of the top-three oils, which repelled the flies for the longest time 19 , You can plant the geranium in your garden if you live in the favorable weather conditions mentioned above. Or, you can buy geranium oil, which is the essential oil of this herb. You can easily prepare a spray based on geranium for getting rid of flies. Just add drops of geranium oil to 2 cups of water; pour this mixture into a spray bottle, and spray away.

Lavender is a beautiful plant to look at. It even has a really mesmerizing fragrance, but it also has some really effective therapeutic and insect-repelling effects. You must have bought potpourri with lavender petals, but you may not have noticed that flies never wander around that potpourri, right? Well, lavender can be used as a healing agent for insect bites, as well as a really powerful insect repellent. The leaves of this flower are distilled to produce the aromatic essential oil that can be used on wounds, burns, insect bites, for inducing sleep, etc.

There are several ways you can use lavender to your advantage when flies have caused a menace in your house. Lemongrass is known to scientists by the name of Cymbopogon. It is a tropical island plant native to Asia, Africa, and Australia, and it comes under the grass family. Lemongrass is also used in cooking to provide a lemony flavor to the food items without the acidity, which comes when you use actual lemon juice.

There various names of lemongrass around the world; some of these names are lemongrass, barbed wire grass, silky heads, citronella grass, cha de Dartigalongue, fever grass, tangland, hierba Luisa, gavati chahapati, etc. A study conducted to find out its effect on fireflies was carried out where pads were treated with infected blood. One of the pads was also treated with lemongrass oil. This study suggested the use of lemongrass and its essential oil is one of the best ways to get rid of flies It will keep away flies, and you can also pluck some to use in your kitchen.

Another way you can use it is by purchasing the lemongrass essential oil. Rub it on your skin when you are outdoors in an area with a lot of greenery. For use in your house, you can always make an essential oil spray, by mixing drops of lemongrass oil, water, and unflavored vodka. This spray will work wonders to drive away all the big and small flies in your house. Tea tree is not anywhere related to the tea you have early in the morning.

This is another tree known as tea tree because of its narrow leaves. Its scientific name is melaleuca alternifolia , but all around the world it is either known as tea tree, narrow-leaved paperbark, narrow-leaved ti-tree, or snow in summer. It is a tall shrub type of tree from the myrtle family, which is native to Australia. It is usually found in Queensland, New South Wales, and around other streams and swampy flats.

The leaves are distilled to produce the highly-used tea tree oil. Purchasing it is not a difficult feat as it is available in the departmental stores, online, as well as offline. Studies have been conducted to find out the effect of tea tree oil on various species of flies.

Pest Guides

It was found that this oil was potent even after 24 hours of application. This suggests better efficacy than numerous commercial fly repellent products You can use tea tree oil on the skin to repel flies. But, make sure you add a carrier oil to it, like safflower oil, because this oil alone can dry out your skin.

The second method to use this aromatic oil is by adding it to your diffuser. This will be really helpful indoors. You can also make a spray with tea tree oil, water, and vodka to spray around the house in the damp corners and garbage disposal areas. One of the most useful plants from this family is andiroba because of its insecticidal properties.

This tree can grow to be up to 30 meters in height. It is also known as carapa and crabwood. Andiroba oil is very useful when it comes to repelling and killing flies in the house. You can buy the oil produced from the seeds of andiroba and use it on your skin by making a tonic to repel mosquitoes and flies in and outside the house.

Just add 15 drops of essential oil in a small bottle and fill it with ml of rubbing alcohol. Your fly repellent is ready. Apart from this, you can make a spray with more oil and more alcohol and some water. In a big ml spray bottle, add drops of andiroba oil, 1 cup of unflavored vodka, and 2 cups water. Shake the bottle nicely. Now, spray it on the damp and dirty corners, garbage accumulation areas, or any other areas you can think of.

You can use a gallon plastic milk jug to kill the flies wandering around in your house just by tweaking it a little and converting it into a fly trap. You have to understand the basic principle, on which this trap works. The flies will enter the jug because of the bait that we will put inside it. The location and replenishing of the bait is a very important task that needs to be taken care of for proper functioning of this trap; to maintain its efficacy for long. This trap should be hung about 3 feet above the floor in a corner with light, but minimum human traffic to lure the flies.

The bait should be replaced every week to ensure the trap keeps working at its best for a long time. If you see more than flies trapped in one week, you should call your local health department and inform them because this could be a serious manifestation To make this trap, you will need a gallon plastic milk jug, commercial fly bait or rotten apples, strings strong enough to suspend the trap in the air, nails to attach the strings to the ceiling, and honey.

First of all, pour honey into the jar and swirl the jar. This will cover the inside surface completely with the honey. Drain out the extra honey and make 3 holes in the neck of the jug to add suspension strings. If the opening is too big; cover some of it with paper to leave a hole of about 3cms in diameter. With the help of the strings, suspend this jar in the air at about 3 feet in a place with light, but with fewer humans around You will notice flies will be caught inside the bottle and will die.

Just wash the inside of the jar and treat it with honey and rotten apple like before. Now, hang it again after a week. The good in this is that this trap will help you get rid of tiny flies and black garbage flies too This is yet another fly trap that can only be used once. Though, sticky ribbons fly trap is available in the market, but here is how to make this trap at home.

The basic principle behind this trap is the sticky surface of the ribbons on which the flies get stuck. All the people who know how to kill flies swear by this method. And, it will work to your advantage if you hang a couple of these ribbons in the suspected areas where flies usually breed. The height at which you have to suspend this trap will remain same as the previous traps that we have discussed, at 3 feet above the ground There are some demerits of these ribbons; the biggest is that you have to replace them once they are filled with flies.

They will catch lesser flies as compared to the jar trap. They can get a little messy, and you have to keep them away from exhaust fans and other fans. There are some advantages too, as this one is cheaper and easier to prepare, it takes less time to prepare, and it is completely non-toxic The length should be somewhere around 8 inches and width should be 2 inches. In a pan, add an equal amount of corn syrup and water. Now, heat this till the solution starts to boil. Do not forget to stir the mixture at all times.

Remove the ribbons from the pan and hang them in a room with the fan turned on. This will dry the strips making them ready to trap the flies. Hang the dried fly-trapping ribbons in the infested and suspected areas, and leave them. Just make sure there is a minimum flow of air and human traffic in that area so that flies can be attracted towards the trap.

Replace with fresh strips as soon as it is full of flies. This method of eradicating flies is as simple as it gets. No fancy baits or hanging fly traps, but just your plain old vacuum cleaner and your talent. If you use a vacuum cleaner on a daily basis, the experience will come in handy when using it to trap flies. Any hand-held vacuum cleaner will work just fine. But, it is suggested that you use the one with batteries or a long wire for free movement. As expected the expression of several hundred of genes was affected by viral infection of WT MEFs with genes showing upregulation and genes showing down regulation when compared with non-infected cells Figure 4B and Table 1.

These results indicate that WNV KUN infection induces profound changes in the transcriptome of murine cells and these changes are reflected across numerous pathways. A Virus titres in the infected cell culture supernatants were assayed by plaque assay at 0 and 48 hpi. B Heat map showing top differentially expressed genes ranked by log fold change between different experimental conditions.

All 3 viruses, however, did induce upregulation and downregulation of a large number of host transcripts in both cell types when compared to Mock cells Table 1 suggesting that MEFs mount significant antiviral response upon infection with these viruses. An unexplored consequence of PRF in the NS2A gene is its potential impact on altering the expression of viral proteins.

Because Flavivirus proteins are produced from a large single polyprotein, all viral proteins in the absence of PRF should be produced in equimolar amounts. That is, proteins located in the viral genome before the PRF site will be produced from each translatable molecule while proteins located after the PRF will be only produced in molecules not undergoing PRF Figure 1A. As a consequence, the occurrence of PRF should affect translation of all non-structural proteins and cause a de-facto change in the ratio of structural to non-structural proteins during translation of the Flaviviral genome Figure 1A.

Electroporated cells were lysed with RIPA buffer at 48, 72 and 96 hours post electroporation. Error bars represent standard error of the mean of 2 independent experiments. However, during viral infection structural proteins assemble into viral particles that are secreted into media during viral secretion. To inhibit virion secretion, cells were treated with metabolic inhibitor brefeldin A BFA [36].

The addition of BFA late in the infection drastically reduces the amounts of secreted structural proteins virions without affecting viral protein synthesis [36] and hence it should reduce the effect of secretion on ratio of structural to non-structural proteins. After 2 hours of labelling and 4 hours of chase the cell monolayers were harvested and lysed in RIPA buffer. Radiolabelled lysates were then immuno-precipitated with anti-E and anti-NS5 monoclonal antibodies and precipitated proteins were separated by SDS-PAGE and visualized after exposure to a phosphor-imaging screen.

This reduction was more evident in cells treated with BFA, indicating that virus secretion depleted viral structural proteins within the infected cell, as expected. These results indicate that the presence of PRF in the NS2A gene of WNV alters the equimolar ratio of viral structural and NS proteins, in the replicon or virus infection settings, demonstrating a role for PRF in translational regulation of viral protein synthesis.

Birds serve as natural reservoir vertebrate hosts for WNV. Specifically, house sparrows HOSPs have been used previously as a natural avian host in order to assess genetic determinants of host competence as representative WNV avian model hosts [33] , [37] — [39]. It should be noted that significant variations in susceptibility to WNV infection are common between individual wild-caught HOSPs [40].

Error bars represent standard errors of the mean. The ability for the virus to infect and disseminate from the midgut was assessed in both experiments, while the ability for mosquitoes to transmit the viruses was also assessed in experiment 2. Twelve days post exposure, mosquitoes were processed by removing the legs and wings, and collecting the saliva using a forced salivation technique. We also examined the ability for the virus to replicate in and be transmitted by Cx.

Bypassing the midgut produced higher rates of infection with the mutant viruses, with almost all mosquitoes becoming infected, irrespective of the virus inoculated Figure 7A. Despite the high rates of infection for the 3 viruses, the titers of virus within the bodies were significantly lower in the mutant viruses than the WT virus Figure 7C. This potentially led to the lower transmission rate observed in the mutant viruses when compared to the WT virus, with the rate being significantly lower in mosquitoes inoculated with A30P Figure 7A.

This is in contradiction to the findings of Winkelmann et al. However, it is possible that the effect observed in those experiments was due to the use of a heterologous trans-encapsidation model where WNV replicon RNAs were packaged by dengue virus structural proteins since when WNV structural proteins were used for packaging WNV replicons, the difference in packaging efficiency between PRF-competent and PRF-deficient replicon RNAs was greatly reduced [26].

These differentially expressed genes included transcription factors, protease inhibitors, and ER stress response elements. Importantly however, all of these differences despite being relatively small were highly significant indicating that even relatively small changes in gene expression may have biological significance. Further studies should focus on determining the role for each of these differentially expressed host genes in WNV-host interactions in vivo.

These differentially expressed genes in response to A30P infection include transcription factors, anti-apoptotic signals, and thermo-tolerance factors. Variant analysis of virus populations by Ion Torrent sequencing detected a significant population of genomes in the WT swarm that contained PRF-abolishing mutation at position not present in the WT genomic sequence proportion column in Table 5 , 0.

The significance of the position, and the PRF events, was underscored by our observations in position Further studies will be required to elucidate the true meaning of the existence of this virus sub-population, however it is likely that regulation of PRF frequency is employed by the virus to maintain the right balance between higher and lower replication efficiencies as the result of more or less efficient PRF event.

We demonstrated that PRF altered the levels of structural and non-structural proteins synthesis creating a de-facto over-expression of structural proteins over non-structural proteins; to our knowledge, this is the first time that the effect of the PRF on the expression of flavivirus proteins has been demonstrated.

In both examples maintaining precise ratios of frameshifting is crucial for virus accumulation and we would argue that similar mechanisms might be required during infection of mosquitoes and birds with WT and PRF-deficient WNVs. The difference between in vitro and in vivo results is often seen for the bird phenotype [39]. Interestingly, in contrast to our results in avian DF-1 cells, JEV PRF mutant virus replicated significantly less efficiently than wild type JEV virus in DF-1 cells [25] , suggesting that difference exists also between different albeit closely related flaviviruses in their ability to replicate in the absence of PRF in vitro.

In this context, the role of insect gut barriers and its interaction with the flavivirus genome is critical. Increased viral accumulation in the gut has been reported to correlate with the ability of the arboviral infection to spread throughout the mosquito and determine its capacity to transmit infection by bite [52].

Efficient infection of the midgut is likely to trigger a robust innate response by the host including, but not limited to, stimulation of enzymes involved in the oxidative stress response and re-epithelialization of damaged cells of the midgut wall [53] , [54]. It is intriguing that the PRF motif is highly conserved among the JEV serocomplex viruses that utilize both Culex mosquito vector and avians as their primary vertebrate replication hosts while other flaviviruses that utilize primate and Aedes vectors such as Dengue virus 1—4 and Yellow fever viruses or rodents and ticks have not demonstrated to encode PRF.

The results presented herein show the role of PRF as mechanism for modulation of the stoichiometric ratio of structural to non-structural genetic determinants that could be involved in modulating mosquito RNAi responses or potentially avian innate immune responses. Passage 0 viruses were harvested 1—3 days post electroporation, titrated by plaque assays, and used at noted multiplicity of infection MOI.

Culture supernatant was harvested and viral tiers were determined by plaque assay [55] at 0, 42, 66, and 90 hpi. The raw signal intensity was extracted from the encrypted binary. The raw data were processed to stabilise the variance [57] and the Quantile normalization methods within the Limma package of Bioconductor were implemented. In addition to the normalization of the experimental data, an averaging of the duplicated array probes was performed so the number of analytical features decreased to the number of uniquely identified probes. The expectation value for maximum accepted error corrected probability was defined as 0.

The distribution of the base quality scores across the reads were typical for Ion Torrent data and in both samples the median sequence length was approximately nucleotides in length. A manual review of the sequence alignment was performed and identified single nucleotide deletion events occurring in both genomes but only present in the forward strand were excluded from further analysis; these deletion variants were deemed a consequence of the Ion Torrent sequencing technology.

House sparrows HOSPs were collected under approved animal care and use protocols and field studies did not involve endangered or protected species. Viral inocula were diluted in PBS 0. Inoculated HOSPs were bled once daily by jugular venipuncture through 7 dpi.

  7. For virus exposure by blood feeding, 5—10 days old mosquitoes were allowed to feed on a blood meal consisting of WT or mutant viruses diluted in commercially available defibrinated sheep blood using the pledget method of Wells [60]. We also explored accumulation and spread of the WT and mutant viruses following IT inoculation. IT inoculation bypasses the midgut and associated barriers while also allowing for standard amounts of virus to be delivered directly producing a more accurate determination of the replication abilities of the virus within the mosquito [61].

    For IT inoculation, 5—10 day old mosquitoes were inoculated with approximately nl of virus suspension. After 12 days incubation, mosquitoes were processed to determine infection, dissemination and transmission rates. Mosquitoes were anaesthetized with CO 2 gas and the legs and wings removed. Detection of the virus in the legs and wings indicates that the virus has escaped from the midgut and has disseminated through the hemocoel [52].

    Following transmission attempts, the saliva expectorate were placed in 2 ml vials containing 0.
