Aphids: a winged response

Adult Intermediate-Winged Aphids Not Physiologically Intermediate.

A guide to the winged aphids (Homoptera) of Costa Rica.

This guide is a compilation of limited morphological and biological information on the winged morphs of 60 species of aphids that have been collected in Costa Rica. It should not be viewed as a definitive taxonomic treatise on the aphids of Costa Rica, rather it is a tool that can be used to assist in research on the biology, host plant relationships, taxonomy, and virus transmission capabiliti...

Winged Pea Aphids Can Modify Phototaxis in Different Development Stages to Assist Their Host Distribution

The pea aphid, Acyrthosiphon pisum (Harris) (Hemiptera: Aphididae), shows wing polyphenism (winged and wingless morphs) in its life cycle. The winged morph is adapted for dispersal; its two developmental adult stages (for dispersal and reproduction) are based on its breeding periods. The two morphs show different phototactic behavior and the winged can change its preference to light according t...

Gene Expression Profiling in Winged and Wingless Cotton Aphids, Aphis gossypii (Hemiptera: Aphididae)

While trade-offs between flight capability and reproduction is a common phenomenon in wing dimorphic insects, the molecular basis is largely unknown. In this study, we examined the transcriptomic differences between winged and wingless morphs of cotton aphids, Aphis gossypii, using a tag-based digital gene expression (DGE) approach. Ultra high-throughput Illumina sequencing generated 5.30 and 5...

Aphids

Historically the diverse areas of communication research have rarely met, and this factor probably prompted my feeling that the order of chapter delivery in this book was counter-intuitive. Naturally our investigation of any communication system has always been heavily influenced by our own language, and the historical progress of research has broadly progressed 'down' from humans to other mamm...
