Extract

This is a report on observations made in the field and in the laboratory in 1954 and 1955 at Fredericton, New Brunswick, on the responses to light and influences of light and temperature on the locomotory activities of introduced insect predators and the motile first-instar larva, or crawler, of the balsam woolly aphid, Adelges piceae (Ratz.). Adults and larvae of the predators were observed in the field and tests were conducted with adults in the laboratory. The species studied were Aphidecta obliterata (L.) and Pullus impexus (Muls.) (Coleoptera: Coccinellidae), Cremifania nigrocellulata Cz. and Neoleucopis obscura (Hal.) (Diptera: Chamaemyiidae) , and Laricobius erichsonii Rosenh. (Coleoptera: Derodontidae). The work is part of an investigation on factors influencing the searching abilities of the predators.
