The black bean aphid, Aphis craccivora was described by Koch in 1854 from Germany. Recently, the genus Aphis Linnaeus, 1758 is subdivided into 6 subgenera : Aphis (s.s.), Bursaphis Baker, 1934, Iowana Hottes, 1954, Maculaphis Zhang and Zhang, 2002, Pseudoprotaphis Kadyrbekov, 2001, Toxoptera Koch, 1856 and Zyxaphis Knowlton, 1947 (Favret, 2016). Aphis craccivora is kept under subgenus Aphis. In...

Facultative bacterial endosymbionts can play an important role in the evolutionary trajectory of their hosts. Aphids (Hemiptera: Aphididae) are infected with a wide variety of facultative endosymbionts that can confer ecologically relevant traits, which in turn may drive microevolutionary processes in a dynamic selective environment. However, relatively little is known about how symbiont divers...

In response to a predator attack, many Aphidinae species release an alarm pheromone, which induces dispersal behavior in other individuals within the colony. The major component of this pheromone is the sesquiterpene (E)-β-farnesene (Eβf), but variations occur between aphid species. In the present work, we collected, identified, and quantified the alarm pheromone of Aphis craccivora Koch (Hemip...

The family Geminiviridae comprises seven genera differentiated by genome organization, sequence similarity, and insect vector. Capulavirus, an eighth genus, has been proposed to accommodate two newly discovered highly divergent geminiviruses that presently have no known vector. Alfalfa leaf curl virus, identified here as a third capulavirus, is shown to be transmitted by Aphis craccivora. This ...

Many insects are associated with heritable symbionts that mediate ecological interactions, including host protection against natural enemies. The cowpea aphid, Aphis craccivora, is a polyphagous pest that harbors Hamiltonella defensa, which defends against parasitic wasps. Despite this protective benefit, this symbiont occurs only at intermediate frequencies in field populations. To identify fa...

Lupin plants are frequently damaged by various herbivorous invertebrates. Significant among these are slugs and aphids, which sometimes attack the same plants. Relationships between aphids, slugs and food plant are very interesting. Grazing by these pests on young plants can lead to significant yield losses. There is evidence that the alkaloids present in some lupin plants may reduce grazing by...

The availability of mitochondrial genome data for Aphididae, one of the economically important insect pest families, in public databases is limited. The advent of next generation sequencing technology provides the potential to generate mitochondrial genome data for many species timely and cost-effectively. In this report, we used transcriptome sequencing technology to determine all the 37 mitoc...

The cowpea aphid, Aphis craccivora Koch (Hemiptera: Aphididae), is one of the most destructive insect pests of legume plants worldwide. Although outbreaks of this pest occur annually in Thailand causing heavy damage, its genetic structure and demographic history are poorly understood. In order to determine genetic structure and genetic relationship of the geographic populations of this species,...

Aphidius transcaspicus Telenga, a mealy plum aphid (Hyalopterus pruni Geoffroy) parasitoid from the Mediterranean, was recently introduced into Hawaii for control of invasive aphids. Under laboratory conditions the parasitoid successfully attacked several important aphid pests in Hawaii, including the melon aphid Aphis gossypii Glover, the banana aphid Pentalonia nigronervosa (Coquerel), the gr...
