Can a leafhopper rescue tea from climate change?

Eric Scott

Ph.D. Candidate, Tufts University

When insect herbivores feed on agricultural crops, they are labeled as destructive “pests”. In addition to decreasing crop yields, feeding by insects causes plants to defend themselves by producing secondary metabolites, many of which are important for the flavor and aroma of our foods. Tea farmers in Taiwan began taking advantage of this phenomenon in the 1930s to produce a high-quality tea called “Eastern Beauty Oolong” which can only be made from tea plants infested with the tea green leafhopper, Empoasca onukii. However, as the climate changes, the abundance of agricultural pests is expected to increase, which could threaten this innovative style of tea through changes in tea plant chemistry as leafhopper damage increases.

The talk is free and open to the public. The meeting is readily accessible via public transportation. Parking is available in the Oxford Street Garage with advance arrangement, as described here, or (usually but not always) at spaces on nearby streets. Everyone is also welcome to join us for dinner before the talk (beginning at 5:45 PM) at the Cambridge Common, 1667 Mass Ave., Cambridge.

CEC meetings are held the second Tuesday of the month from October through May. The evening schedule typically includes an informal dinner (5:45 to 7:15 PM) followed by our formal meeting (7:30 – 9:00 PM). The latter begins with club business and is followed by a 60-minute entomology related presentation. Membership is open to amateur and professional entomologists.

Strangers in the Night:

Has light pollution led to firefly declines?

Avalon C. S. Owens

CEC President

Ph.D. candidate, Tufts University

Why do fireflies flash? Because they want to be seen! But their unique bioluminescent courtship signals can be obscured by street lamps, house lights, and other sources of nighttime light pollution — and if we’re not careful, our lights might extinguish theirs forever. Learn more about the total impact of light pollution on firefly reproduction, and methods whereby fireflies, moths, and other essential members of the nocturnal ecosystem can continue to coexist with humans on this increasingly urbanized planet.

Avalon Owens is a Ph.D. candidate in the Department of Biology at Tufts University, where she studies the impact of light pollution on North American fireflies. She earned her Masters degree in Entomology from National Taiwan University, and hosts a bilingual educational YouTube channel called INSECT ISLAND.
