Refuges and host shift pathways of host-specialized aphids Aphis gossypii
Scientific Reports, 2017 Polyphagous cotton-melon aphid populations usually comprise cotton- and cucurbit-specialized biotypes. Host-specialized aphids are prone to food shortages.

Symbionts protect aphids from parasitic wasps by attenuating herbivore-induced plant volatiles
Nature Communications, 2017 Plants respond to insect attack by releasing blends of volatile chemicals that attract their herbivores’ specific natural enemies, while insect herbivores may carry endosymbiotic microorganisms that directly improve herbivore survival after natural enemy

Rapid Identification of Aphid Species by Headspace GC-MS and Discriminant Analysis
Insects, 2023 Aphids are a ubiquitous group of pests in agriculture that cause serious losses. For sustainable aphid identification, it is necessary to develop a precise and fast aphid identification tool. A new simple chemotaxonomy approach to rapidly identify aphids

Facultative bacterial symbionts in aphids confer resistance to parasitic wasps
Proceedings of the National Academy of Sciences of the United States of America, 2003 Symbiotic relationships between animals and microorganisms are common in nature, yet the factors controlling the abundance and distributions of symbionts are mostly unknown.

Journal of Sustainable Agriculture and Environment, Volume 1, Issue 4, Page 262-274, December 2022., 2022 Abstract Introduction The proximity of semi‐natural habitats and agricultural fields in an agricultural landscape leads to unavoidable biological, chemical, and physical interactions. Fungi can negatively influence, but also support crop growth in agricultural fields.

Advancing Early Detection of Virus Yellows: Developing a Hybrid Convolutional Neural Network for Automatic Aphid Counting in Sugar Beet Fields [PDF]
arXiv, 2023 Aphids are efficient vectors to transmit virus yellows in sugar beet fields. Timely monitoring and control of their populations are thus critical to prevent the large-scale outbreak of virus yellows. However, the manual counting of aphids, which is the most common practice, is labor-intensive and time-consuming.

Scientific Reports, 2017 (E)-β-farnesene (EβF) is the major component of the alarm pheromone of many aphid species, but where EβF is synthesized in aphids is only partly understood.

A New Dataset and Comparative Study for Aphid Cluster Detection [PDF]
arXiv, 2023 Aphids are one of the main threats to crops, rural families, and global food security. Chemical pest control is a necessary component of crop production for maximizing yields, however, it is unnecessary to apply the chemical approaches to the entire fields in consideration of the environmental pollution and the cost.
