Natural enemy-herbivore networks along local management and landscape gradients in urban agroecosystems.

open access: yesEcological Applications, 2020
Ecological networks can provide insight into how biodiversity loss and changes in species interactions impact the delivery of ecosystem services. In agroecosystems that vary in management practices, quantifying changes in ecological network structure ...

Apparent competition drives community-wide parasitism rates and changes in host abundance across ecosystem boundaries [PDF]

open access: yes, 2016
Species have strong indirect effects on others, and predicting these effects is a central challenge in ecology. Prey species sharing an enemy (predator or parasitoid) can be linked by apparent competition, but it is unknown whether this process is strong

Optimum timing for integrated pest management: Modelling rates of pesticide application and natural enemy releases [PDF]

open access: yes, 2010
Many factors including pest natural enemy ratios, starting densities, timings of natural enemy releases, dosages and timings of insecticide applications and instantaneous killing rates of pesticides on both pests and natural enemies can affect the ...

Evolution of Host Defense against Multiple Enemy Populations [PDF]

open access: yes, 2016
Natural and managed populations are embedded within complex ecological communities, where they face multiple enemies. Experimental studies have shown that the evolution of host defense mechanisms to a focal enemy is impacted by the surrounding enemy ...

Cover crops improve early season natural enemy recruitment and pest management in cotton production

open access: yesbioRxiv, 2019
A shift to more ecologically based farming practices would improve the sustainability and economic stability of agricultural systems. Habitat management in and around agricultural fields can provide stable environments that aid in the proliferation of ...

Broad spectrum pesticide application alters natural enemy communities and may facilitate secondary pest outbreaks

open access: yesPeerJ, 2017
Background Pesticide application is the dominant control method for arthropod pests in broad-acre arable systems. In Australia, organophosphate pesticides are often applied either prophylactically, or reactively, including at higher concentrations, to ...

Movement Patterns of Carabid Beetles Between Heterogenous Crop and Noncrop Habitats [PDF]

open access: yes, 2018
Habitats adjacent to crop fields can increase natural enemy populations by providing additional food, shelter and overwintering sites. While many studies have focused on the role of non-crop borders for supporting natural enemies, here we investigate the

The Response of Natural Enemies to Selective Insecticides Applied to Soybean [PDF]

open access: yes, 2012
Natural enemies of the invasive pest Aphis glycines Matsumura can prevent its establishment and population growth. However, current A. glycines management practices include the application of broad-spectrum insecticides that affect pests and natural ...

The effect of within-crop habitat manipulations on the conservation biological control of aphids in field-grown lettuce [PDF]

open access: yes, 2011
Within-crop habitat manipulations have the potential to increase the biological control of pests in horticultural field crops. Wildflower strips have been shown to increase the abundance of natural enemies, but there is little evidence to date of an ...

Characterization of the natural enemy community attacking cotton aphid in the Bt cotton ecosystem in Northern China

open access: yesScientific Reports, 2016
Planting Bt cotton in China since 1997 has led to important changes in the natural enemy communities occurring in cotton, however their specific effect on suppressing the cotton aphids (being notorious in conventional cotton ecosystem) has not been fully
