Diagnosis of intrapopulation adaptation genesis of bird cherry aphid Rhopalosiphum padi (L.) under nutrition conditions on various spring common wheat varieties

Зерновое хозяйство России, 2023
The widespread cultivation of highly productive varieties of agricultural crops often leads to the emergence and spread of new intraspecific forms of insects capable of mass reproduction.

T(w)o Patch or Not T(w)o Patch: A Novel Biocontrol Model

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT A number of top‐down biocontrol models have been proposed where the introduced predators' efficacy is enhanced via the provision of additional food (AF). However, if the predator has a pest‐dependent monotone functional response, pest extinction is unattainable. In the current manuscript, we propose a model where a predator with pest‐dependent

Discovery, Identification, and Insecticidal Activity of an Aspergillus flavus Strain Isolated from a Saline–Alkali Soil Sample

Microorganisms, 2023
Aphids are one of the most destructive pests in agricultural production. In addition, aphids are able to easily develop resistance to chemical insecticides due to their rapid reproduction and short generation periods.

Understanding the effects of patch‐burn grazing management on aboveground grassland invertebrate biodiversity

Oikos, EarlyView.
Landscape heterogeneity is widely recognized as a driver of biodiversity, yet its consequences for above‐ground, foliage‐dwelling insect communities under active grassland management remain underexplored. Patch‐burn grazing (PBG), which rotates fire across patches within a grazed landscape, is designed to promote spatial and temporal heterogeneity by ...

Plant and insect functional traits influence herbivore performance under climate change

Oikos, EarlyView.
Climate change is expected to disrupt many trophic interactions, including those between insect herbivores and their host plants, which could have detrimental effects at the ecosystem level. However, the response of insect herbivory to climate change can vary widely across species, and an understanding of the mechanisms underlying this variation is ...

Aphid Genomics and its contribution to understanding aphids as crop pests

, 2017
This chapter considers some examples of how aphid genomes have contributed to understanding aphids as crop pests. It aims to give a very broad overview of areas where genomics has contributed to understanding aspects of aphid biology, ecology, behaviour ...

Area‐restricted search under realistic constraints

Oikos, EarlyView.
Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...

THE EFFECT OF AGRO-ECOLOGICAL ZONES ON THE INCIDENCE AND DISTRIBUTION OF APHID VECTORS OF PEPPER VEINAL MOTTLE VIRUS, ON CULTIVATED PEPPER (CAPSICUM ANNUUM L.) IN NIGERIA [PDF]

Journal of Central European Agriculture, 2011
The distribution of aphid vectors of Pepper veinal mottle virus (PVMV) was studied on cultivated pepper between 2003 and 2005 in the major pepper producing areas of the six agro-ecological zones in Nigeria.

Building capacity in vector‐borne plant virus research: The CONNECTED Network

PLANTS, PEOPLE, PLANET, EarlyView.
Plant viruses spread by insects decimate crop yields globally, causing food security challenges in vulnerable areas, including regions of Africa. Interdisciplinary research is needed to protect future crop supplies. CONNECTED, the Community Network for African Vector‐Borne Plant Viruses, increased research capacity in Central, East, West and Southern ...
