Large-scale gene discovery in the pea aphid Acyrthosiphon pisum (Hemiptera)

, 2006
Aphids are the leading pests in agricultural crops. A large-scale sequencing of 40,904 ESTs from the pea aphid Acyrthosiphon pisum was carried out to define a catalog of 12,082 unique transcripts.

Macroecological relationships of ant diversity with increasing aridity in Australian tropical savannas: contrasting responses of epigaeic and hypogaeic assemblages

Ecography, EarlyView.
Studies using climatic gradients play a key role in our understanding of the importance of rainfall and temperature as factors regulating species diversity and distribution, and thus of likely responses to climate change. However, such studies currently consider above‐ground species only, ignoring the diverse hypogaeic (subterranean) invertebrate fauna.

Cold hardiness and overwintering survival of the grain aphid Sitobion avenae in Northern England [PDF]

, 1987
Laboratory maintained Sitobion avenae of all developmental stages had a mean inherent supercooling ability below -20°C. Acclimation alone, or in conjunction with starvation had no significant effect on supercooling.

Studies on polyphagous predators of cereal aphids

, 1979
1. Experiments were done in fields of winter wheat at North Farm, West Sussex, and at Rothamsted in 1978 to investigate the effect of predation by carabid beetles and other polyphagous preadtors on populations of cereal aphids. 2.

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

PLoS 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.

Developing Plantain for Resistance to Banana Aphids by RNA Interference

Proceedings, 2020
Banana bunchy top virus (BBTV) is one of the world’s invasive species. Banana aphid (Pentalonia nigronervosa) is found in all banana producing areas and it is the insect pest known to transmit BBTV causing banana bunchy top disease (BBTD) in ...

Does the Application Flow Rate of Nutrient Solutions Prepared in Brackish Water Affect Coriander Production?

Irrigation and Drainage, EarlyView.
ABSTRACT Flow rates for applying nutrient solutions in hydroponic systems are empirically known, yet uncertainties remain regarding whether brackish water affects the optimal flow rate and, consequently, biomass production and allocation. This study evaluated whether variations in application flow rate affect coriander biomass when brackish water is ...

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

Heliyon
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

BMC 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

Parasitoids (Hymenoptera: Braconidae, Aphidiinae) of the mealy plum aphid Hyalopterus pruni (Geoffr.) on common reed (Phragmites australis) in different types of habitat in Poland [PDF]

Archives of Biological Sciences, 2013
The aim of the present work was to determine the parasitoid guild of the mealy plum aphid Hyalopterus pruni on common reed (Phragmites australis) in different types of habitats in central Poland.
