Ballistics and Visual Targeting in Flea-Beetles (Alticinae)

Journal of Experimental Biology, 1995
ABSTRACT The kinematics of jumping was measured in seven species of flea-beetle (Alticinae). The accuracy of two species during targeted jumping was also investigated. Take-off accelerations ranged from 15 to 270 times gravity. Rotational energy accounted for 4–21 % of the total translational energy. Two species were able to control jump

Insecticide and Acaricide Tests, 1978
Abstract ‘Julian’ sweet potato sprouts were transplanted June 2 in 3-ft rows with 12-inch spacing. Treatment plots were replicated 3 times and arranged in a randomized complete bl ock design. Each plot consisted of five 25-ft-long rows with 2 untreated rows adjacent to each plot. The soil type was a sassafras fine sandy loam.
