Jumping of flea beetles onto inclined platforms
Journal of Comparative Physiology A, 2022The flea beetle, Altica cirsicola, escapes predators by jumping and landing in a dense maze of leaves. How do they land on such varied surfaces? In this experimental study, we filmed the take-off, flight, and landing of flea beetles on a configurable angled platform. We report three in-flight behaviors: winged, wingless, and an intermediate winged mode.

Flea Beetle Control in Canola, 1989
Insecticide and Acaricide Tests, 1992Abstract On 8 May, a cooperative trial with Sigco Research was established in Pennington county near St. Hilaire, MN. Plot size were six 38.1 cm rows, 6.10 m in length, planted with a cone type 6-row planter. The trial was arranged in a randomized complete block design, replicated 4 times.

Flea Beetle and Sawfly Control, 1988
Insecticide and Acaricide Tests, 1989Abstract Materials were applied on 23 May to 23- by 23-ft plots in a crop-year lowbush blueberry field at Gray, Maine. A second application of Dylox (8 oz) and M-one (both rates) was made on 2 Jun. There were 3 replications in a randomized complete block design with 10-ft untreated buffer strips around each plot.

Ballistics and Visual Targeting in Flea-Beetles (Alticinae)
Journal of Experimental Biology, 1995ABSTRACT 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.
