Project Summary
Black soldier flies (Hermetia illucens) are a species of insect native to warm-temperate regions. The larvae of this species are able to survive on waste material, recycling the nutrients as they generate residue that can be used as agricultural fertilizer. Larvae can also used as feedstock for animals such as poultry, reptiles, and fish. For these reasons, their application to locally-grown food and waste recycling is Black soldier fly adults are inactive in cold climates. If we could develop a means to elicit mating under artificial conditions, it could make their benefits available worldwide. The objective of this study was to test whether artificial light sources such as compact fluorescent light bulbs (CFLs) and light-emitting diodes (LEDs) could stimulate mating to the same or greater degree as sunlight, thereby overcoming the dependency on sunlight for the survival of this species in northern locations. We tested two experimental light sources, CFLs and LEDs, versus sunlight, the control. To do this, we designed and engineered three chambers. Each chamber was dedicated to a type of light. We conducted this experiment twice. No egg clusters were found in either trial. We suspect that subjects were too far developed into the adult egg-laying period by the time the experiment began for the adults to lay eggs, and that the larvae are very sensitive to temperature and humidity conditions as they pupate and mate. We propose continuing this work to better determine the most critical environmental controls for black soldier fly mating.

I am a senior, and I have been at Breck since kindergarten. I have always had a love for math and its applications, which has sparked an interest in science. Asides from Advanced Science Research, I have participated in many of the activities Breck has to offer such as student government, the Student Diversity Leadership Conference, and Unified Sports. I am also a member of the Breck track team, and you can usually find me out there during the spring, asking myself why I signed up. When I'm feeling lazy, I love to reread Harry Potter, watch Tasty videos, listen to Spotify, and eat food.

My name is Cassidy Yueh, Breck School Class of 2017. My scientific areas of interest comprise environmental science focusing on sustainability and alternative materials engineering for a better future, including purification of waste. I am also interested in studying interactions between ecology and entomology. In my free time, I like to read, and my favorite book is Wall and Peace by Banksy. My favorite animals are Felis catus and Odontodactyllus scyllarus. I am quite the squirrel enthusiast. I particularly enjoy the Jelly Belly Candy Company™ black licorice jelly bean.

"More than anything, ASR has taught me the value of failure. In real world research, failures are never published, but in actuality, failures happen much more often than successes. By facing obstacles that arose during our research, I learned that a determined scientist troubleshoots these failures, adjusts the experiment, and tries again."
"I've grown so much during my experience in Breck Advanced Science Research. I've been exposed to STEM careers, and I've garnered graduate-level research experience. I've learned life skills such as writing papers, promoting teamwork, and presenting information. ASR has been my favorite class at Breck."
