WASTELAND ACTIVISM: Political Weeds and Ecological Imaginaries in Montreal

International Journal of Urban and Regional Research, EarlyView.
Abstract Drawing on ethnographic fieldwork in Montreal, this article examines the ways in which urban dwellers and activists engage with the living materialities of wastelands to illuminate evolving ecological imaginaries and their political potentials.

Development and survival of Bemisia tabaci MEAM1 (Hemiptera: Aleyrodidae) on Eucalyptus genotypes

Agricultural and Forest Entomology, EarlyView.
This study provides the first experimental evidence of the biological performance of Bemisia tabaci MEAM1 on Eucalyptus genotypes. Development time was shortest and viability highest on soybean compared with the evaluated Eucalyptus genotypes. B. tabaci MEAM1 completed its development on Eucalyptus camaldulensis and Eucalyptus urophylla × Eucalyptus ...

Does a pea-cereal intercropping under shallow ploughing compensate for the higher weed growth compared to deep ploughing in organic farming?

Julius-Kühn-Archiv, 2012
The reduction of soil tillage depth is of special interest in organic farming. However, shallow ploughing often results in higher weed abundances in comparison to deep ploughing.

Weed infestation control using a p-fuzzy model

OBSERVATÓRIO DE LA ECONOMÍA LATINOAMERICANA
In the context of the use of mathematical models to describe the population dynamics, the present work aims to propose a model using Fuzzy Rule Based Systems (SBRF) to describe the control of weed population dynamics, from the point of theoretical view.

Temperature interacts with jack pine host defences to influence the growth of mountain pine beetle‐associated fungi

Agricultural and Forest Entomology, EarlyView.
Optimal growing temperatures varied with mountain pine beetle‐associated fungal species. There was only a marginal impact of temperature on the response of fungi to defensive monoterpenes of novel host pine. Interspecific facilitation occurred for Leptiographuim longiclavatum when grown in Ophiostoma montium‐induced treatments at optimal temperatures ...

Assessing the host plants of the invasive apricot aphid, Myzus mumecola (Hemiptera: Aphididae)

Agricultural and Forest Entomology, EarlyView.
We investigated the host plants of the invasive apricot aphid Myzus mumecola (Hemiptera: Aphididae), an emerging pest species in Europe, by combining molecular and ecological approaches. The winter host plant was confirmed as apricot by both methods.

Pruning slash drives ambrosia beetle (Curculionidae: Scolytinae, Platypodinae) activity in Khaya grandifoliola C.DC.: Slash removal as a preventive management strategy Resíduos de poda aumentam a atividade de besouros da ambrosia (Curculionidae: Scolytinae, Platypodinae) em Khaya grandifoliola C.DC.: A remoção dos resíduos como estratégia preventiva de manejo

Agricultural and Forest Entomology, EarlyView.
Slash retention increased ambrosia beetle activity in Khaya grandifoliola, acting as both breeding substrate and source of attractive volatile cues that promoted localized population buildup. Beetle attacks occurred only near retained slash, while no attacks were recorded in slash‐removal plots, demonstrating that residue removal effectively prevents ...
