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

open access: yesMicroorganisms, 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.

Untapped Sources of Dual Resistance to Hessian Fly and Greenbug in Synthetic Hexaploid Wheats

open access: yesPlants, 2023
The Hessian fly (Hf) and greenbugs (Gb) are major pests of wheat, causing severe economic losses globally. Deploying resistant wheat is the most effective strategy for managing these destructive insects.

Facilitation of Sclerotinia sclerotiorum infestation by aphid feeding behaviour is not affected by aphid resistance in oilseed rape

open access: yesHeliyon
The relation between aphids and Sclerotinia stem rot (SSR) in oilseed rape is rarely examined because they are often studied alone. We have observed a significant correlation between the number of aphids and the occurrence of SSR in our field studies ...

Aphid reproductive investment in response to mortality risks

open access: yesBMC Evolutionary Biology, 2010
Background Aphids are striking in their prodigious reproductive capacity and reliance on microbial endosymbionts, which provision their hosts with necessary amino acids and provide protection against parasites and heat stress. Perhaps as a result of this

Differential Susceptibility of Coleomegilla maculata and Scymnus creperus Larvae to Aggression by Solenopsis invicta Workers

open access: yesInsects, 2023
The biological control of aphids by aphidophagous coccinellids is often hampered by aphid-tending ants or aggressive, invasive ants foraging for food.

Aphids (Hemiptera: Aphidoidea) associated with native trees in Malta (Central Mediterranean) [PDF]

open access: yes, 2009
In the present study 25 aphid species which are known to be associated with trees in the Maltese Islands are recorded. Of these, 18 species represent new records; these include Aphis craccivora, Brachyunguis tamaricis, Cavariella aegopodii ...

Aphid secondary symbionts do not affect prey attractiveness to two species of predatory lady beetles.

open access: yesPLoS ONE, 2017
Heritable symbionts have been found to mediate interactions between host species and their natural enemies in a variety of organisms. Aphids, their facultative symbionts, and their potential fitness effects have been particularly well-studied.

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]

open access: yesJournal 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.

Wing dimorphism in aphids [PDF]

open access: yesHeredity, 2006
Many species of insects display dispersing and nondispersing morphs. Among these, aphids are one of the best examples of taxa that have evolved specialized morphs for dispersal versus reproduction. The dispersing morphs typically possess a full set of wings as well as a sensory and reproductive physiology that is adapted to flight and reproducing in a ...

Genome sequence of the pea aphid Acyrthosiphon pisum [PDF]

open access: yes, 2010
Aphids are important agricultural pests and also biological models for studies of insect-plant interactions, symbiosis, virus vectoring, and the developmental causes of extreme phenotypic plasticity.
