Aphids are prominent phloem-feeding insect pests. Myzus persicae and Acyrthosiphon pisum are generalist and specialist species, respectively. In this study, these two aphid species were used to investigate host acceptance and plant resistance to aphid ...

Grass Hosts of Cereal Aphids (Hemiptera: Aphididae) Between Wheat-Cropping Cycles in South Dakota [PDF]
Several grasses may serve as alternative hosts for cereal aphids during the interim between small-grain crops in South Dakota, but field studies to determine which grasses are important have not been undertaken.

A New Perspective on the Co-Transmission of Plant Pathogens by Hemipterans
Co-infection of plants by pathogens is common in nature, and the interaction of the pathogens can affect the infection outcome. There are diverse ways in which viruses and bacteria are transmitted from infected to healthy plants, but insects are common ...

Abundance of Rice Root Aphid Among Selected Plant Species and on Plants Grown With Different Soil-Surface Media [PDF]
The rice root aphid, Rhopalosiphum rufiabdominalis (Sasaki), is distributed worldwide and colonizes a wide range of plants. However, relatively little is known about the suitability of different host plants, optimal rearing techniques, and the aphid’s ...

A new species of gall-forming aphid from China, Qiao jinshaensis gen. et sp. nov., is described from Rhus wilsonii Hemsl. Morphological identification and molecular analyses both support the establishment of a new genus.

The prevailing paradigm of host-parasite evolution is that arms races lead to increasing specialisation via genetic adaptation. Insect herbivores are no exception and the majority have evolved to colonise a small number of closely related host species ...

Aphidiinae (Hymenoptera, Braconidae) aphid parasitoids of Malta : review and key to species [PDF]
This paper brings an annotated list of the 16 aphid parasitoids detected up to 2015 in Malta. All the species were reared from identified aphid-plant associations. An illustrated key to the identification of the recorded species from Malta is provided.

Chemical signalling between aphids (small insects that suck plant sap) formating and avoidance of antagonistic organisms, and between aphids and plants for location of hosts or avoidance of unsuitable plants, employs minute levels of small lipophilic molecules (SLMs), termed "semiochemicals". These semiochemicals, which include sex and alarm pheromones,

A Mutation in Amino Acid Permease AAP6 Reduces the Amino Acid Content of the Arabidopsis Sieve Elements but Leaves Aphid Herbivores Unaffected. [PDF]
The aim of this study was to investigate the role of the amino acid permease gene AAP6 in regulating phloem amino acid composition and then to determine the effects of this altered diet on aphid performance.
