Mission: Field investigation

Date: May 13, 2018
Location: Shenzhen University’s field station, Longhua district, Shenzhen

Pest infections seriously affect the yield and quality of vegetables, we wanted to do something to help with this problem. In order to know more about the situation of pest infection, we did a field investigation at Shenzhen University’s field station and found that a striped flea beetle is the most serious kinds of pests. We collected some of these beetles back for species identification.

Mission: Expert consultation

Date: May 13, 2018
Location: Zoological Laboratory, Shenzhen University.

To identify this highly destructive species, we went to Shenzhen University for expert consultation. Under the supervision of Professor Wang, we observed the beetle under microscope, and identified its physical characteristics. we learned that this beetle belongs to Phyllotreta Striolata. After the analysis, the professor taught us how to make specimens.

Mission: Farmers interview

Date: August 8, 2018
Location: Shenzhen University’s field station, Longhua district, Shenzhen.

To find out what approaches the farmers are currently using to control Phyllotreta Striolata, we went to Shenzhen University’s field station again and were told that currently, traditional chemical pesticide is the only effective way to prevent infestation. We also gathered information about the existing brands of pesticides and their uses on the market.

Mission：Rapid Pesticide residue detection on vegetables from small farmer’s market

Date: August 14, 2018
Location: Research lab at Shenzhen University

We wanted to find out if extensive use of chemical pesticide would cause food safety problems, thus, we performed pesticide residue detection using quick pesticide detection method we learned from internet. Pesticide residues were detected from the vegetables we tested.

Mission：Pesticide residue detection on vegetables from supermarket

Date: August 18, 2018
Location: Food Inspection Center of Shenzhen

We were astonished by the pesticide residue detection results, and wanted to confirm the pesticide residue situation using more accurate and reliable methods. We then went to the Food Inspection Center of Shenzhen for further experiments. With the help of the technicians, we did the experiments, and found out that the Pakchoi contains three types of pesticide residue which are fliorosilazole 0.057mg/kg, worm nitrile 0.124mg/kg and cypermethrin 0.188mg/kg.

Mission：A survey about food safety

Date: August 20, 2018
Location: Online

We wondered: are the general public aware of the commonly existed food safety problem? Do they know how to deal with this problem? Therefore, we did an online survey and received 1414 answer sheets. After analysis, we found many people don’t treat pesticide residue before cooking, and some of them do not know how to remove pesticide residues from vegetables.
