Observations on the Biology and Control of Pest Trichoptera at Fort Erie, Ontario

Abstract

The community of Fort Erie, Ontario, and the waterfront zone of Buffalo, New York, form one of the many areas in the St. Lawrence River drainage system that are annually infested by large numbers of adult Trichoptera and, to a lesser degree, Ephemerida. Betten (1934) reported on a field study, conducted in 1906, of the Trichoptera found at Buffalo, N.Y. He noted the prevalent species and the extent of the problem chat the insects create for the local inhabitants. The medical aspect was investigated by Parlato (1929, 1930, 1932) and Osgood (1934). In August, 1950, an investigation of the scale, composition, and source of the trichopteran infestation and possible control measures was initiated at Fort Erie, Ontario.

A systematic study of the nearctic larvae of the Hydropsyche morosa group (Trichoptera : Hydropsychidae) /

“…As well, sheer numbers of insects flying and perishing are a nuisance. Several attempts at control have been conducted at Fort Erie, Ontario (Peterson, 1952) and lie Ste-Helene, Quebec (Fredeen. 1971…”

The Abatement of Nuisance Species of Trichoptera With DDT Applied to the Resting Sites of Adults

“…Throughout, this program was under the direction of Mr. Thompson, who provided me (in 1969 and1970) with the following information in personal letters and in newspaper clippings.

“…Peterson (1952) discovered that DDT applied to the resting places of adult Trichoptera in trees and shrubs at Fort Erie, Ont., provided residual effects that lasted for several days. These outbreaks made it obvious that an adulticide could not dependably prevent Trichoptera from swarming in nuisance densities on the island and plans for a second adulticide test were cancelled to allow intensified research into alternative abatement schemes.…”

Adult caddisflies (Trichoptera) collected by a light trap in the Myojin Area in Kamikochi, Chubu Sangaku National Park, Japan

“…Because the larvae of caddisflies are usually abundant in freshwater, the mass emergence of the adults often leads to severe nuisance conditions i.e., obstruction of business, poor visibility, traffic mess, and a very foul odor (Munroe, 1951;Peterson, 1952;Osgood, 1957;Fredeen, 1972). In Japan, massive emergence of caddisflies, Cheumatopsyche brevilineata (Iwata), during summer season has much annoyed the citizens beside the Kamo River in Kyoto, so Yagi and Sasakawa (1992) reported on life history and swarming behavior of C. brevilineata.…”
