EFFECTS OF FLEA BEETLES ON THE YIELD OF RADISH

Entomologia Experimentalis et Applicata, 1970
The yield of dry matter of radish attacked by adult flea beetles in the field was negatively and linearly related to the number of feeding lesions/unit area of leaf, when both sets of values were transformed logarithmically. The nature of the relationship is discussed.ZusammenfassungDIE WIRKUNG VON ERDFLOH‐BEFALL AUF DEN ERTRAG BEI RETTICHENDie ...

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-

Protective Row Covers for Management of Flea Beetles in Organic Eggplant Production in the Southeastern US

Crops
Organic eggplant production in the United States is challenged by flea beetles, which stunt eggplant growth and reduce yield. Across four experiments between 2019 and 2024, we compared the effects of various pest management strategies on flea beetle ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

From settler gardens to digital naturalists: human aesthetic preferences and land use changes facilitate the biogeographical expansion of a wild plant–virus interaction

PLANTS, PEOPLE, PLANET, EarlyView.
Anthropogenic facilitation of wild plants based on aesthetic preferences for particular traits can change the biogeography and ecology of natural communities. We use a mixed‐methods socioecological approach to characterize the ways in which humans interact with a common, widely distributed plant and a generalist viral symbiont that induces an ...

RNA degradomics and proteomics reveal the mechanism of dsProsβ1‐mediated proteasome targeting in Psylliodes chrysocephala

Pest Management Science, EarlyView.
RNA degradomics revealed dsProsβ1‐derived siRNA‐mediated mRNA cleavage events, mainly at uracil‐guanine and adenine‐adenine pairs. Proteasome inhibition via dsProsβ1 increased mitochondrial and cytoskeletal proteins while reducing translation‐related and mRNA‐binding proteins.

Spectrum of the pests on cereal crops and influence of soil fertilisation

Plant Protection Science, 2008
Our research was realised on spring barley and winter wheat in Nitra-Dolná Malanta during 2004-2006. We found that the total occurrence of the pests had decreasing tendency.

Combined effects of canola plant density and insecticide management strategies on flea beetle abundance, canola defoliation, and yield across the Canadian prairies

Pest Management Science, EarlyView.
Increasing canola plant density reduced flea beetle abundance per plant and increased yield, independent of region or insecticide use, highlighting its potential as a component of integrated pest management. Abstract The crucifer flea beetle, Phyllotreta cruciferae (Goeze), and the striped flea beetle, Phyllotreta striolata (Fabricius) (Coleoptera ...
