, 2017
Aphidius colemani Viereck parasitizes several economically important aphid pests of small grain crops including the greenbug, Schizaphis graminum and the Russian wheat aphid, Diuraphis noxia. The ability of A. colemani to switch from S.

Mapping Determinants in Cucumber Mosaic Virus for Transmission by Aphis gossypii

Virology, 1994
Determinants have been mapped in the coat protein of cucumber mosaic virus (CMV) which influence transmission by the aphid Aphis gossypii. Chimeric RNA 3s were constructed which contain sequences from the efficiently aphid-transmitted strain Fny-CMV and the very poorly aphid-transmissible M-CMV. Analyses of chimeric viruses revealed that two regions in

Competitive Interactions Between Generalist Predators and Their Effects on Shared and Non‐Shared Pests in a Greenhouse Crop

Entomologia Experimentalis et Applicata, EarlyView.
Orius laevigatus engages in unidirectional intraguild predation on Transeius montdorensis. Despite this, both predators coexisted and suppressed the shared thrips prey. Aphids, a non‐shared prey, were effectively controlled by O. laevigatus even when its population was limited due to intraguild predation. T.

If Only You Could Catch Me—Catch Me If You Can: Monitoring Aphids in Protected Cucumber Cultivations by Means of Sticky Traps

Horticulturae, 2023
Aphids are important pests in many greenhouse and field crops. For plant protection, early detection of relevant species and reliable assessment of population development throughout the season is mandatory to address countermeasures in time. In practice,

Ecological Characteristics of Aphidophagous Menochilus Sexmaculatus Fabricius and its Performance Against Aphis Gossypii Glover [PDF]

, 1996
The chilli aphid, Aphis gossypii Glover (Homoptera: Aphididae) (here after abbreviated as AG), is vector of the chilli veinal mottle virus (CVMV) and is a main pest of chilli in Malaysia. The aphidophagous Menochilus sexmaculatus Fabricius (Coleoptera:

Feeding Preference and Foraging Behaviour of Eriopis connexa on Two Aphid Species

Journal of Applied Entomology, EarlyView.
ABSTRACT Aphids are phloem‐feeding insects that cause both direct and indirect damage to crops, reducing agricultural productivity. Among the available pest control strategies, biological control using natural enemies is a sustainable and effective approach. The ladybird Eriopis connexa (Germar, 1824) is a generalist predator known for its voracity and

Life table and demographic parameters of the coccinellid predatory species, Hippodamia convergens Guérin-Méneville (Coleoptera: Coccinellidae) when fed on two aphid species

Egyptian Journal of Biological Pest Control, 2020
The study aimed to determine the effect of two aphid species; Lipaphis erysimi (Kaltenbach) and Aphis gossypii Glover (Hemiptera: Aphididae) on life table and demographic parameters of Hippodamia convergens Gu`erin-M´eneville (Coleoptera: Coccinellidae).

Bumble Bees and Honey Bees on Islands Harbour Reduced Viral Species Richness, Yet Honey Bee Populations Are Dominated by a Deformed Wing Virus Recombinant

Molecular Ecology, EarlyView.
ABSTRACT Pollinators harbour diverse RNA viromes that play a vital role in their health. Yet, factors that shape viral communities are often unclear. The European honey bee (Apis mellifera) is experiencing a viral epidemic since the emergence of the parasitic mite Varroa destructor (varroa) introduced vector‐borne transmission, which has also been ...

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.
