Three aphid species were identified as new records for Turkey aphid fauna from Bartin province. These species are Ceruraphis viburnicola (Gillette) (Hemiptera: Aphididae), Dysaphis apiifolia (Theobald) (Hemiptera: Aphididae) and Macrosiphum mordvilkoi Miyazaki (Hemiptera: Aphididae). These records increase the recorded aphid-fauna of Turkey to 433 species.

apterous viviparous female of dysaphis inulae sp. n. living on inula britanica and d. lappae cynarae (theobald) living on silybum marianum is described and newly recorded from iran, respectively. the latter aphid species is redescribed and an identification key for the species of dysaphis boerner on asteraceae is also presented.

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...

Interactions between wild flora, crops, aphids (Hemiptera, Aphididae) and their natural enemies in citrus orchards

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...

Chlorophyll degradation enzyme (i.e., chlorophyllase, Mg-dechelatase, and chlorophyll oxidase) activities of aphid-infested and uninfested 'Tugela' and Tugela near-isogenic wheat lines (i.e., Tugela-Dn1, Tugela-Dn2, and Tugela-Dn5) were assayed. Chlorophyllase activity was higher in bird cherry-oat aphid, Rhopalosiphum padi (L.) (Homoptera: Aphididae),-infested wheat lines compared with Russian...

the influence of parasitoids on population dynamics is affected by host instar preference. the preference pattern of host instars is not fixed and is modified by the availability and relative abundance of host instars, intensity of defensive behaviors in a particular instar, and also maternal effects of the female forager. in this study, host instar preference of the thelytokous strain of lysip...

Hyperomyzus (Neonasonovia) pullatus Hall & Garraway sp. n (Hemiptera: Aphididae) is described based on apterous specimens collected from Eupatorium sp., (Asteraceae) in Jamaica. Photos and illustrations are provided. It is compared with an undescribed species from Costa Rica. It is distinguished from Hyperomyzus (Neonasonovia) nigra (Baker) by having narrower siphunculi, less secondary rhinaria...
