[Mosquito Control] Baiting Hobby Leads to Mosquito Research

Supplement - Mosquito Control

Entomology student Matthew Thorn’s interest in the field began early, and recently his passion for bugs resulted in the discovery of a new species in Mississippi.

Bugs provoke shudders or shrieks from many people, but Matthew Thorn seeks them out.

Three years ago, Thorn’s hobby led him to discover the Japanese rock pool mosquito in Mississippi, a mosquito that had never before been reported in the state. Thorn collected the insect in its larva stage in Itawamba County, and after the adult emerged, he identified it and was shocked by his findings.

“At first I thought, ‘This can’t be right. I must have made a mistake,’” said Thorn, then a recent high school graduate. “So I contacted Wendy Varnado at the Mississippi State Department of Health, and she confirmed I was right.

“It is difficult to tell the difference between this mosquito and other mosquitoes in their larval stages,” Thorn said. “The adult is a little larger than many mosquitoes in Mississippi and has some distinguishing silver markings, but even a scientist needs a microscope to tell the difference.”

Thorn said the mosquito is found in its native Japan in rock crevices filled with water. It is believed to have entered the United States in 1998 in New Jersey and has been spreading slowly throughout the country.

Humble Begginings.
Thorn, who dabbled in collecting insects since middle school, at one point wanted to be a medical doctor. But attending Mississippi State University’s Bug Camp for four years and interacting with the staff at MSU’s Mississippi Entomological Museum changed all that.

“The first bug collection I did was for a class project in middle school,” Thorn said. “I thought it was interesting, but I didn’t pursue it much after that. Then I went to Bug Camp, and it radically changed the way I viewed entomology.”

The camp also awakened his desire for a career in entomology.

“There is so much diversity in the field of entomology,” said Thorn, who plans to enroll at MSU this year. “There are so many different ways to use the knowledge gained studying insects. It’s very exciting.”

Thorn is passionate about the field of entomology. “Matthew has a tremendous enthusiasm for entomology,” said Richard Brown, director of the Mississippi Entomological Museum at MSU, where Thorn worked last summer. “Insect taxonomy is something only a very few people have the desire and tools to study. It is an innate talent that certain people are born with.”

A Bright Future. Thorn’s appetite for entomology is being fed at the entomological museum, where he was responsible for sorting through hundreds of exotic insect species, separating them into family groups and flagging possible threats to agriculture and natural resources for further expert study. The insects were submitted from trap samples in Mississippi, Alabama and Kentucky.

“Entomology has many disciplines and involves both physiology and pest management and others,” said Brown, who is also an entomology professor in the Biochemistry, Molecular Biology, Entomology and Plant Pathology department at MSU. “The study of entomology involves much more than how to kill insects. The field requires a desire to truly understand them and how they fit into our environment. I see that desire in Matthew, and I know he has great potential for a career in entomology.”
