Living on the Edge: Using and Improving Trap Crops for Flea Beetle Management in Small-Scale Cropping Systems. [PDF]
Insects, 2019 The use of trap crops to manage pest insects offers an attractive alternative to synthetic pesticides. Trap crops may work particularly well at smaller production scales, being highly amenable where crop diversification and reduction of synthetic inputs ...

Flea Beetle Control in Canola, 1994A [PDF]
Arthropod Management Tests, 1995 Abstract Plots were planted 6 May near Pomeroy, WA, at a rate of 6 lb/acre in rows 7 inches apart. Plots were 20 × 2 ft, replicated 4 times with a RCBD, and were situated with replicates perpendicular to a grass field. Precounts (PrCt) of plant stand per 6.6 ft row, and damage on 20 randomly selected plants on a scale of 0 to 6, with 0 =

Identification and evolution of glucosinolate sulfatases in a specialist flea beetle. [PDF]
Sci Rep, 2019 AbstractGlucosinolates, a characteristic group of specialized metabolites found in Brassicales plants, are converted to toxic isothiocyanates upon herbivory. Several insect herbivores, including the cabbage stem flea beetle (Psylliodes chrysocephala), prevent glucosinolate activation by forming desulfo-glucosinolates. Here we investigated the molecular

Flea Beetle Control, 1996 [PDF]
Arthropod Management Tests, 1997 Abstract Materials were applied on 6 Jun to 20 by 20 ft plots in a bearing blueberry field at Jonesport, Maine. There were 3 replications of each treatment and a minimum 5-ft untreated buffer strip around each plot. Treatments were blocked according to prespray population levels.

Species‐specific plant‐mediated effects between herbivores converge at high damage intensity [PDF]
, 2021 Plants are often exposed to multiple herbivores and densities of these attackers (or corresponding damage intensities) often fluctuate greatly in the field. Plant-mediated interactions vary among herbivore species and with changing feeding intensity, but

Flea Beetle Control, 1993 [PDF]
Arthropod Management Tests, 1994 Abstract Materials were applied on 26 May for early instar BFB larval control to 20- by 20-ft plots in a pruned blueberry field at Otisfield, Maine. There were 3 replications of each treatment in a RCBD with a minimum 5-ft untreated buffer strip around each plot. Insecticides were applied at a rate of 25 gal/acre using a COrpropelled, 30-

Flea Beetle Control, 1997 [PDF]
Arthropod Management Tests, 1998 Abstract Materials were applied on 11 Jun to 20- by 20 ft-plots in bearing blueberry fields at Jonesport (Test 1) and Township 19 (Test 2), Maine. There were 3 (Test 1) or 4 (Test 2) replications of each treatment and a minimum 5-ft untreated buffer strip around each plot.

Long-Term Dynamics of Leafy Spurge (\u3ci\u3eEuphorbia esula\u3c/i\u3e) and its Biocontrol Agent, Flea Beetles in the Genus Aphthona [PDF]
, 2008 Three flea beetle species (Aphthona spp.), first introduced into North America in 1988, have come to be regarded as effective biological control organisms for leafy spurge (Euphorbia esula). The black flea beetles (Aphthona lacertosa and A. czwalinae) in

Aggregation Behavior of a Willow Flea Beetle, \u3ci\u3eAltica Subplicata\u3c/i\u3e (Coleoptera: Chrysomelidae) [PDF]
, 2017 This study examined the aggregation behavior of a specialist insect herbivore, Altica subplicata (Coleoptera: Chrysomelidae), on its host plant, Salix cordata. Mark-recapture experiments were conducted in patches of S. cordata growing along the shores of
