Dinning Together in Feng Wu

Experience Sharing of Capturing Bloodsucking Flies in the farm：
　Dr. Tzeng told us the livestock farmers used to borrow the Insect light trap from them to capture the Bloodsucking Flies. To our surprise, he said the light trap can capture thousands of insects at just one night. Aditionally, they also had some cooperation program with livestock farmers. At that time, they used many different interesting approaches, like colors & light to test the behavior of Bloodsucking Flies. This experience sharing made us learn some basic methods of testing insects’ behavior.

The Art of Insect Rearing for Them：
　Dr. Tzeng told us insect rearing is not only a branch of knowledge, but a kind of art. For example, when malaria was a pandemic disease all over the world, some related research had difficulty in obvious progression, because Anopheles gambiae had not been reared successfully at that time. However, since a researcher from United Kingdom had success in rearing Anopheles gambiae in lab, the malaria disease had been completely researched, and the health life of human had been improved. This concept raised a great inspiration for how to do the research of our project.

Suggestion of Our Harmful Insects--Bactrocera dorsalis：
　Dr. Tzeng told us the bactrocera dorsalis is a serious problem for Taiwanese agriculture, which causes 17 billions dollors of loss every year. Our government had used many methods ( like：air drop many non-fertility bactrocera dorsalis to the farm ), trying to solve this problem, but finally failed. Dr. Tzeng suggested Bactrocera dorsalis as the target harmful insect of our project to solve the main problem of Taiwanese agricultural insects damage.

Discussion about Ecological Equilibrium Problem of Our Project：
　As for the ecological equilibrium problem of our project, Dr. Tzeng thought foundamentally we human farm in the area, having caused harm to nature. If you persist in the ecological equilibrium problem, then you have to ask yourself why you do farming and cause harm to the environment？Dr. Tzeng gave us a special view point, highlighting in the beginning, we human who do farming to survive have caused harm to the environment, so we shouldn’t inspect the ecological equilibrium problem of capturing insects.

Experience Sharing of Dengue Fever Prevention and Control：
　Dr. Tzeng shared the interesting experience of his presentation about Dengue Fever Prevention and Control at many town offices and also introduced there are two kinds of dengue fever vector mosquito, one is Aedes albopictus outdoors and the other is aedes aegypti indoors. We not only learned simple knowledge of dengue fever but also realized the feeling of helping people with professional knowledge.

Explanation of the Real Function of Mosquito PBAN：
　In fact, the mosquito PBAN is activated during spreading wings when the mosquito emerges from its pupa. Initially, the mosquito wings are all living cells and when its PBAN regulates some hormones to make some cells apoptosis, just leaving few cells alive on its bone of wings, it finally forms transparent wings. This explanation about mosquito PBAN gave us a deeper realization about PBAN.

Take a Look at Their Mosquito Breeding Cage and Insect Light Trap ：
　Dr. Tzeng let us take a look at Culex pipiens molestus (the underground house mosquito) breeding cage, and also introduced the behavior of many kinds of mosquito. This mosquito breeding cage inspired us many new ideas about our insects testing box. In fact, we mimicked the same concept of mosquito breeding cage to test our PBAN effect simply.

　　

Further Discussion about our project：

　Dr. Tzeng have enthusiasm on discussing our project. To prevent any problem from happening, Dr. Tzeng and we inspected all the probability which may cause our project failed like PBAN degeadation in insects’ intestine ( whether we have to use little thuricide to cause some holes on insects’ intestine to make it absorb our PBAN easily ) and the restriction of our project ( we have to capture the first “female” insect in our device, and actually our project work. ). In the discussing process, we inspected many problems again, and also get many suggestion from Dr. Tzeng. We hoped we can overcome all the problems, and improve our project.

Advantages Discussion of Our Device：
　Referring to our project, we use PBAN to make the harmful insects produce pheromone for us to help us attract many same kinds of insects. Dr. Tzeng was very interested in our project, and thought compared to the common use (Pheromone Trap & Pesticide ) in the market, our main idea have no dug resistance problem ( PBAN is insects’ physiologically natural substance ) and have no worry about the problem of running off our PBAN ( PBAN can be mass produced from our E.coli. ). It is a very user-friendly、eco-friendly and perfect project.

　In briefly conclusion, our team and Dr. Tzeng had deep discussion in this visitation. Not only experience sharing but also project inspection made us learn much and got many new ideas which let us realize how to make use of our project to achieve the best effect.
