Aggregation Behavior of a Willow Flea Beetle, \u3ci\u3eAltica Subplicata\u3c/i\u3e (Coleoptera: Chrysomelidae) [PDF]

open access: yes, 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

The effect of different seeding densities of linseed (Linum usitatissimum L.) on flax flea beetles (Coleoptera: Chrysomelidae)

open access: yesJournal of Plant Protection Research, 2017
Linseed, one of the oldest cultivated crops, is again gaining in importance, mainly due to its nutritional benefits and biomedical applications. Therefore, it is expected that herbivores will also exist in greater abundance.

Effects of Soil Moisture on the Pupation Behavior of \u3ci\u3eAltica Subplicata\u3c/i\u3e (Coleoptera: Chrysomelidae) [PDF]

open access: yes, 2017
The effects of soil moisture on the pupation behavior of a willow flea beetle, Attica subplicata, were studied with two laboratory experiments. To test the effect of soil moisture on the number of larvae pupating and pupal survival, we set up pupation ...

Species‐specific plant‐mediated effects between herbivores converge at high damage intensity [PDF]

open access: yes, 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

Between-Site Variation in Suitability of \u3ci\u3eSalix Cordata\u3c/i\u3e as a Host for \u3ci\u3eAltica Subplicata\u3c/i\u3e (Coleoptera: Chrysomelidae) [PDF]

open access: yes, 2017
To investigate local adaptation of insect herbivore populations to host plant populations, willow flea beetles (Altica subplicata) were collected from two distant sites in northern Michigan (Grass Bay, GB; Pte. Aux Chenes, PAC) and reared on host plants (
