Bacterial communities of the cotton aphid Aphis gossypii associated with Bt cotton in northern China.

Aphids are infected with a wide variety of endosymbionts that can confer ecologically relevant traits. However, the bacterial communities of most aphid species are still poorly characterized. This study investigated the bacterial diversity of the cotton aphid Aphis gossypii associated with Bt cotton in northern China by targeting the V4 region of the 16S rDNA using the Illumina MiSeq platform. ...

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...

Aphis gossypii

BIOLOGY/ECOLOGY Dispersal mechanisms Flight range of winged adults is very limited. Long-range dispersal of eggs, immature stages and adults is manmediated with the transport of infested plant material. Reproduction The taxonomic status of this alien aphid is problematic, and hence the interpretation of biological information is difficult. Moreover, different biotypes exhibiting host preference...

Natural Attachment Sites for Capilliconidia of Neozygites fresenii (Entomophthorales: Neozygitaceae) on Cotton Aphids Aphis gossypii (Homoptera: Aphididae)

The cotton aphid fungus, Neozygites fresenii (Entomophthorales: Neozygitaceae) is an important pathogen of the cotton aphid Aphis gossypii (Glover) (Homoptera: Aphididae). The capilliconidia of this pathogenic fungus adhere to the integument of aphids, beginning the cycle of mycosis. Few studies have been conducted that attempt to quantify or examine the points of infection of an entomopathogen...

Host Races of the Cotton Aphid, Aphis gossypii, in Asexual Populations from Wild Plants of Taro and Brinjal

Worldwide, several studies have shown that adaptation to different host plants in phytophagous insects can promote speciation. The cotton aphid, Aphis gossypii Glover (Homoptera: Aphididae: Aphidini), is a highly polyphagous species, but its populations increase by parthenogenetic reproduction alone in Indian subcontinent. This study showed that genotypes living in wild plants of taro, Colocasi...
