Light trap

Date : 31st January 2008
Weather : Windy
Attendance : Alicia Tan, Audrey Wong, Chen Dexiang
Location : Opposite Carpark on the road behind King Edward VII hall, nearing NUH



Yup, that's a light trap we set today. Got it borrowed from Lynn, Ecology lab. Also got 4 tubes of ethanol for tomorrow's catch. We're going to make it a 12 hours trap. Another good news was we managed to get insecticide strip from Lynn's mentor. So nice of him to get it for us. The trap was set up approximately 7.30pm and going to retrieve it at 7.30am.

We also planted a pitfall trap approximately 10 meters away from the light trap. This time, I improved on the pitfall by adding salt(a lot of it) and detergent into the solution in pitfall.

The last pitfall trap only got one silverfish. I hope this trap will get something better. Last one was a mistake, but we learn from mistakes and it was a trial, so it's okay. Things will be more intensed after Chinese New Year holidays.

At every spot, different methods will be used to sample the relative diversity of insects. I'm hoping to get all the traps done in 2 weeks, maximum.

Trial Pitfall

Attendance : Audrey Wong, Alicia Tan

Bought ziplocks and polystyrene cups from NTUC and going to start my project soon. Because I'm still not too sure of what I'll be getting. Thought it'll be nice to put two pitfalls at the back of King Edward Hall so I went with Alicia and we planted two pitfalls there. I hope I can get something interesting from there tomorrow when I retrieve it.
Dexiang has already got the fish nets for us to make sweep nets. Miss Luah shall be contacted soon so we will be able to sew the nets.
So far, the traps we're planning to use are:
1. sweet nets
2. pitfall
3. leaf litter
4. malaise trap
5. light trap(different types of light traps will be confirmed)
Vegetation part has been done by Dexiang and Theresa because Alicia and I had some replacement lecture that day. However, Mr. Siva still need to take a look at the map they came out with to approve if it's correct and appropriate for our insect traps to be set up.
Stay tune for tmr's trap results..
