Entomopathogenic fungi stimulate transgenerational wing induction in pea aphids, Acyrthosiphon pisum (Hemiptera: Aphididae)

, 2012
1. Aphid natural enemies include not only predators and parasitoids but also pathogens, of which fungi are the most studied for biological control.

Characterization of the dynamic microbiome evolution across thrips species

Insect Science, EarlyView.
Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.

The comparison of yellow cylindrical, flat and water traps, and of johnson suction traps, for sampling aphids

, 1957
Different traps were compared to find the type most suitable for studying aphid vectors of plant viruses quantitatively. A Moericke water trap caught more aphids than a flat sticky trap of equal area. A flat sticky trap (930 sq.

Annual flower strips under the ‘Sweden Blossom’ initiative – how do they perform for pollinators, natural enemies and herbivores?

Agricultural and Forest Entomology, EarlyView.
Pollinator‐targeted annual flower strips increase abundances of pollinators but also natural enemies and herbivores. Natural enemies and herbivores disperse in a taxon‐specific manner into nearby crops. Pest control by ground‐dwellers slightly increases in crop areas near the flower strips.

On Estimating the Population of Aphids in A Potato Field

, 1948
This appendix to the preceding paper by L. Broadbent deals with the statistical problem of estimating the population of aphids per plant in a field of growing potatoes. An unbiased method is described, in which a definite proportion of a number of plants

Managing Friends and Foes: Sanctioning Mutualists in Mixed‐Infection Nodules Trades off With Defense Against Antagonists

Evolutionary Applications
Successful plant growth requires plants to minimize harm from antagonists and maximize benefit from mutualists. However, these outcomes may be difficult to achieve simultaneously, since plant defenses activated in response to antagonists can compromise ...

Spectral response of guava leaves under infestation by Costalimaita ferruginea (coleoptera: Chrysomelidae)

Agricultural and Forest Entomology, EarlyView.
Coccinellidae (Coleoptera), Miridae (Hemiptera), Hemerobiidae (Neuroptera), Pentatomidae (Hemiptera), Anystidae (Acari), Erythraeidae (Acari) and spiders (Araneidae, Oxyopidae and Salticidae) fed on the invasive paropsine leaf beetles in Marlborough, New Zealand.

Fitness trade-off in peach-potato aphids (Myzus persicae) between insecticide resistance and vulnerability to parasitoid attack at several spatial scales

, 2010
Insecticide-resistant clones of the peach-potato aphid, Myzus persicae (Sulzer), have previously been shown to have a reduced response to aphid alarm pheromone compared to susceptible ones.

Evaluating the efficacy of tagging adhesives for insect tracking

Agricultural and Forest Entomology, EarlyView.
Two‐part epoxy resin delivered the strongest RFID tag adhesion on carabid beetles, exceeding polyvinyl acetate, cosmetic latex and cyanoacrylate adhesives. Adhesive performance was consistent across Harpalus, Leistus and Poecilus; species effects were non‐significant, supporting a broadly applicable protocol for carabid RFID tagging studies.

Assessing the host plants of the invasive apricot aphid, Myzus mumecola (Hemiptera: Aphididae)

Agricultural and Forest Entomology, EarlyView.
We investigated the host plants of the invasive apricot aphid Myzus mumecola (Hemiptera: Aphididae), an emerging pest species in Europe, by combining molecular and ecological approaches. The winter host plant was confirmed as apricot by both methods.
