Prey Range and Voracity of Main Insect Natural Enemies of Pests in Corsican Clementine Orchards

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
To assess the biocontrol potential on the main arthropod pests of clementine orchards in Corsica, laboratory experiments were carried out using five potential predators. Their prey range and voracity were tested on three pest species. Then, a global predation rate index was calculated at the scale of the entire community of insect predators.

Comparison of the biology of Myzus persicae Sulz. resistant and susceptible to dimethoate

open access: yes, 1970
SUMMARY Apterous Myzus persicae resistant to dimethoate reproduce for the same length of time as susceptible aphids, but the resistant ones reproduce significantly faster during the first 10 days of adult life (especially during the first 5 days ...

Global patterns in genomic diversity underpinning the evolution of insecticide resistance in the aphid crop pest Myzus persicae

open access: yesCommunications Biology, 2021
Singh, Bass and colleagues generate new genomic resources for the aphid crop pest, Myzus persicae, comprising a chromosome-scale genome assembly and resequenced genomes of >100 globally sampled clonal lines.

Plant Traits and Reproduction in a Multitrophic System: The Role of Aphids, Parasitoids and Hyperparasitoids

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
This field mesocosm study examined the top‐down effects of hyperparasitoids, parasitoids and aphids on plant growth and fitness. Parasitoids reduced aphid populations, but this effect was attenuated by hyperparasitoids. However, these multitrophic interactions did not affect plant traits and reproduction, likely due to the plant's fast life cycle and ...

The evolution of insecticide resistance in the peach-potato aphid, Myzus persicae

open access: yes, 1998
The peach–potato aphid Myzus persicae (Sulzer) can resist a wide range of insecticides, but until recently (1990) the only mechanism identified was the increased production of carboxylesterases (E4 or FE4), which cause enhanced degradation and ...

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

open access: yesEcological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

Transcriptomic and proteomic signatures underlying nymphal adaptation and foam production in the forage pest Mahanarva spectabilis

open access: yesInsect Molecular Biology, EarlyView.
RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...

Isolation and characterization of a novel lectin gene, Allium triquetrum agglutin, conferring insecticidal properties against Myzus persicae

open access: yes, 2009
Myzus persicae, more commonly known as green peach aphid, is an important pest in agriculture. Each year it causes great losses to agricultural and horticultural plants. It feeds on sap in the phloem, the main transportation route for plant nutrients. It

Evolution of imidacloprid resistance in Myzus persicae in Greece and susceptibility data for spirotetramat

open access: yes, 2017
BACKGROUND: Myzus persicae s.l. is a major crop pest globally and has evolved resistance to a range of insecticide classes making it increasingly difficult to control in some areas.

Ocorrência de formas aladas de pulgões e sua relação com fatores meteorológicos e plantas hospedeiras Occurrence of alate aphids and their relationship with meteorological factors and host plants

open access: yesPesquisa Agropecuária Brasileira, 2010
O objetivo deste trabalho foi determinar o padrão de revoadas e a influência de fatores meteorológicos e de Brassicaceae sobre populações de formas aladas dos pulgões Brevicoryne brassicae, Lipaphis erysimi e Myzus persicae.
