~Insect Time~

In mid July, my course had a field trip to Kampung Tepi Laut, Penaga, Penang at night....to do what?? To catch mosquitoes~ =P

2 methods were used to catch the mosquitoes, 1st - BLC (Bare Leg Catch) , the most sacrificing one T_T we had to expose our leg and waiting for the mosquitoes to come. Then we'll catch it by using a test tube~ Unfortunately (fortunately perhaps?) not much mosquitoes wanted to come over my leg -____-" was my blood not tasty enough to bait them?

2nd method - CBT (Cow Bait Trap). This time, we went into a mosquito net which has trapped a cow inside. The cow was used as a bait to attract the mosquitoes. After they took blood meal and rest on the net, it's our time to catch them! This method is much more efficient than the first one~ LOTS of mosquitoes are being sucked by using an aspirator.

My group has also taken a picture with the cow...but until now I still don't get the soft copy of the picture ==" haiz..

These are part of our collection from that trip =P (I'm the one who decorate this box XD)

Next lab is the glass chamber & peet grady chamber method to test the bio efficiency of mosquito mat...sayang..no picture was taken. but I still managed to take the 3rd experiment, the testing of aerosol on cockroaches!!~~ Aerosol was sprayed on a plat wood and female cockroaches were released. Time started and the time of cockroaches knocked down was noted down~

~A few minutes after the releasing~ only 1 cockroach was down

~After 1 hour~ all cockroaches terbalik =S
