Adult Mosquito Monitoring

The Adult Mosquito Monitoring menu is aimed at allowing you to enter data when adult mosquito populations are being trapped.  You can access the Adult Monitoring menu by clicking on the Monitoring menu in the blue header at the top of the screen and selecting Adult Mosquito Monitoring.

AdultStartScreen

Selecting the Adult Mosquito Monitoring menu

To record data within the Adult Mosquito Monitoring menu requires completion of a four-step process, which you will be guided through by the main screen and three ‘tabs,’ as shown below:

AdultScreenAndTabs

The three tabs of the Adult Monitoring Menu

These four steps are:

  1. Adult Site Setup – the main form where you choose the site, trap type and trap rationale. A map is also provided showing where the site is;
  2. Trap Set – a tab where you input details of when the trap was set and the associated environmental conditions at that time;
  3. Trap Pickup – a tab where you input details of when the trap was collected and associated environmental conditions at that time; and,
  4. Trapped Species – a tab where you can enter the abundance and identifications of mosquitoes collected within the trap.

If you are using the website, you will need to do most of this all at once – so it is best completed when you have finished your trap runs, so that you can populate the Adult Site Setup, Trap Set, and Trap Pickup stages.  After that, you can enter the Trapped Species at any time (which is useful if you send the mosquitoes off for identification).


Adult Site Setup

Please note: before you can setup an Adult Mosquito Monitoring Site, you will need to already have set up the Site (if it is new) in the Sites screen.  For more information on how to set up a Site, please see the specific help on that section.

This main section has a map which will show you where the Site is, and three fields shown in the following figure.

The Adult Mosquito Monitoring site map and starting fields

To record Mosquito Monitoring data, choose the Site from the first field underneath the map. When you click on the Site field, a list of currently recorded sites within your LGA will be listed in alphabetical order.  Select the trap location at which you plan to conduct trapping. Once this is done, the map will re-centre to the location of the Site you have chosen.

You then need to choose the Trap Type being established at the trap location, from the values provided. A range of possible trapping methods have been provided in alphabetical order – these include:

  • Biting Catch – collecting mosquitoes from live animals or humans used as bait for mosquito attraction – not recommended in disease prone areas;
  • BG Trap – Biogents’ Sentinel adult mosquito trap;
  • EVS CO2 – Encephalitis Virus Surveillance Carbon Dioxide traps;
  • Emergence Trap – Adult emergence traps placed over water bodies that are hard to sample for larvae;
  • FTA (updraft catch) – Flinders Technology Associates® used in updraft traps;
  • Ovitrap – Larval monitoring trap for collection of eggs and development of larvae;
  • Sticky Ovitrap – Lethal adult trap to collect female mosquitoes ovipositing eggs within the ovitrap; and
  • Sweep Netting – collection of mosquitoes with a butterfly net.

Please contact the Medical Entomology team to have additional trap types included in the options provided if you are using another technique medical.entomology@health.wa.gov.au.

You then need to select the rationale behind the monitoring, which again is a set of values to choose from, including:

  • Dispersal experiment – for experiments looking at the dispersal of mosquitoes from one location to another;
  • General surveillance – to build knowledge about common mosquitoes collected at a site and their potential disease risks;
  • Public complaint – investigation of a public complaint;
  • Research – to conduct a research project into a specific topic; or
  • Virus detection – to collect mosquitoes for virus screening.

Please contact the Medical Entomology team to have additional trap rationales included in the options provided if you are trapping mosquitoes for another common purpose medical.entomology@health.wa.gov.au.

Please note: throughout the website if you see fields marked with red asterisks (*) then these are Mandatory fields, and must be filled out before you can save the form you are working on.

Once you have chosen these values, you should move on to the next step.  Please note: that if you hit the “Save Trap Record” button after just filling in these fields above, you will be asked to fill out the mandatory fields across all tabs before you can save the record. Once you have completed all fields on a single tab, you should click on the next tab to continue data entry.


Trap Set

When detailing how the trap was set, there are two mandatory fields (note the red asterisk – *); the date and time that the trap was set, and the Trapping Officer.   You must record the time and date when the trap was set to start collecting mosquitoes.  This field is automatically completed with the current time and date when you click on the tab.  It can be manually overwritten by typing over the current characters or by changing the date with the calendar function on the right hand side of the field. Every record requires entry of a corresponding Trapping Officer who set the trap.

There are also a range of additional non-mandatory fields in the form, as shown below.

AdultTrapSetTab2

 

The Trap Set fields

A range of environmental variables have been included to provide data that can later be used for analysing mosquito abundance, species composition and diversity.  Five environmental variables are automatically populated from the nearest Bureau of Meteorology weather station to the site – but you also have the ability to enter your own field observations as well. This weather data integration works when you select a site, and the information comes through so long the recording time is within 72 hrs of the current time.

The top of the form is split into Field observations on the left, and Bureau of Meteorology Observations (grey boxes) on the right. Below that the Contextual Environmental Data contains a number of variables where you can enter values from local observations or other information sources.

These include:

  • Air Temp (°C) – The air temperature at the time the trap was set in degrees Celsius.  A range of values can be added between -10 to 50°C;
  • Humidity (%) – The humidity as a percentage (between 0 and 100) at the time the trap was set;
  • Cloud Cover (%) – The percentage of cloud cover observed at the time the trap was set;
  • Wind Direction – Direction of wind selected from a drop down box of 16 choices when the field is clicked upon;
  • Wind Speed (Km/h) – estimated wind speed in kilometres per hour from the drop down selection provided, including:
    • Not recorded – no wind speed recorded at time the trap was set;
    • Calm – low wind;
    • Light (<20 km/h);
    • Moderate (20-30 km/h);
    • Fresh (30-40 km/h);
    • Strong (40-50 km/h); or
    • Gale (>50 km/h).
  • Last Significant Rainfall Date – The date of the last significant rainfall to affect the site (added manually or by using the calendar on the right of the field);
  • Last Significant Rainfall (mm) – The amount of rainfall at the time of the Last Significant Rainfall Date (above) in millimetres;
  • Last Significant High Tide Date – Date of the last significant tide near the trap site (added manually or by using the calendar on the right of the field);
  • Last Significant High Tide (cm) – Height of the last significant high tide recorded at your trap site (in centimetres);
  • Comments –  A free text comments box to add any information about the field site that may be useful or explain mosquito abundances at a later date.

By selecting a site you will notice automatically captured values appear in green, and details of the nearest weather station, including the Station name, distance from the site, and the date/time of the latest weather observation.

You can click on the “Show all data” button to see the raw data from the Bureau of Meteorology, and the formatted equivalent the system will record against he trap-set record.

Once you have chosen these values, you should move on to the next tab.

Please note: that if you hit the “Save Trap Record” button after just filling in these fields above, you will be asked to fill out the mandatory fields across all four tabs before you can save the record. Once you have completed all fields on a single tab, you should click on the next tab to continue data entry.


Trap Pickup

The fields for the Trap Pickup are similar to those for the Trap Set component (as shown below, click here view the explanations in Trap Set).  You will also note in this screenshot that there is another mandatory field here – Trap Status.  This screenshot shows you what happens when you try to save a record without a mandatory field being filled in – it’s highlighted in red and has a “This field is required” message underneath it.  You cannot save the record until the mandatory field is completed.

AdultTrapPickupTab_mandatory

The Trap Pickup fields and mandatory flags

The fields shown above and layout is very similar to the trap set categories and should be completed at the time the trap is collected from the field.  Two mandatory fields must be completed to save the record including:

  • Pickup Date and Time – the time the trap was collected from the field.  This field is automatically completed with the current time and date when you click on the tab.  It can be manually overwritten by typing over the current characters or by changing the date with the calendar function on the right hand side of the field.
  • Trap Status – four options are available under the Trap Status field including:
    • OK – the trap is in good working order (regardless of whether mosquitoes were collected or not);
    • Trap Failure – a problem has occurred with the trap (mechanical issue) so that no mosquitoes were collected;
    • Trap Stolen/Missing – indicates that the trap was set, but upon return, it is no longer at the location. It has been stolen, vandalised or is missing.
    • Partial Sample – the trap has had some sort of failure, however some mosquitoes remain in the trap, thus only a partial sample was collected.

Five environmental variables are automatically populated from the nearest Bureau of Meteorology weather station to the site – but you also have the ability to enter your own field observations. This weather data integration works when you select a site, and the information comes through so long the recording time is within 72 hrs of the current time.

The top of the form is split into Field observations on the left, and Bureau of Meteorology Observations (grey boxes) on the right. Below that the Contextual Environmental Data contains a number of variables where you can enter values from local observations or other information sources.

The available fields include:

  • Air Temp (°C) – The air temperature at the time trapping was conducted in degrees Celsius.  A range of values can be added between -10 to 50°C;
  • Humidity (%) – The relative humidity at the time of trap pick-up, expressed as a percentage.
  • Cloud Cover (%) – The percentage of cloud cover observed at the time trap was collected;
  • Wind Direction – Direction of wind selected from a drop down box of 16 choices when the field is clicked upon;
  • Wind Speed (Km/h) – estimated wind speed in kilometres per hour from the drop down selection provided.  This includes:
    • Not recorded – no wind speed recorded at time the trap was collected;
    • Calm – low wind;
    • Light (<20 km/h);
    • Moderate (20-30 km/h);
    • Fresh (30-40 km/h);
    • Strong (40-50 km/h); or
    • Gale (>50 km/h).
  • Overnight rainfall (mm) – recorded overnight rainfall in millimetres.
  • Comments –  A free text comments box to add any information about the site that may be useful or explain mosquito abundances at a later date.

Once you have chosen these values, you should move on to the next tab.  Please note: that if you hit the “Save Trap Record” button after just filling in these fields above, you will be asked to fill out the mandatory fields across all tabs before you can save the record. Once you have completed all fields on a single tab, you should click on the next tab to continue data entry.


Trapped Species

The Trapped Species tab allows you to enter the mosquito species collected and the abundance of each species (including the number of females and males) that you have collected from that particular trap.

There is one mandatory field at the top of this tab called “Trap Outcome” which includes three options:

  • Sample not identified – the sample was not identified due to time constraints;
  • Sample lost after collection – the sample cannot be found upon return to the laboratory/office.
  • Sample discarded – the mosquitoes are too damaged to be able to be identified (due to travel or postage handling of the sample).

An additional three fields, as shown below, include the species name, and the number of females and males that were trapped.

trappedspecies

The Trapped Species fields

The Trapped Species field is an auto-complete field (once you have typed three letters into the field) that will start to search through the species that have been recorded in the system (as shown in the Field Guide).  You can then select from the list of names that appear, or keep typing the name to reduce possible options.  It is best to start by typing in the genus (e.g. Aedes) and then start to type the name of the species to be able to reduce the number of possible choices in the drop down list.

The number fields for females and males have been deliberately limited to a range of between 0 and 30,000 individuals – it was seen as very unlikely to get more than 60,000 individuals for one species in one night!  Manually enter the total number of mosquitoes of each species into these two columns.

Initially only five rows have been provided for adding species trapped.  To obtain additional rows, click the Save Trap record button and an additional five rows will be added to the Trapped Species tab allowing you to insert identifications for an additional 5 species.  Again, by clicking the Save Trap Record button, a further five rows will be added.

Adult Mosquito Monitoring additional species id rows

Additional rows for species identifications can be added by clicking the Save Trap Record button

Once you have entered your identification results, you should save the trap record before proceeding.  Hit the “Save Trap Record” button to save the information.  When you do this, you will be taken back to the Adult Mosquito Monitoring tab where you will be able to review any of the completed fields across all tabs.
