The aphid-ant mutualistic relationships are not necessarily obligate for neither partners but evidence is that such interactions provide them strong advantages in terms of global fitness. While it is largely assumed that ants actively search for their mutualistic partners namely using volatile cues; whether winged aphids (i.e., aphids' most mobile form) are able to select ant-frequented areas h...

We tested the utility of 18 previously characterized Aphis spp. microsatellite loci for polymorphism and differentiation among populations of the soybean aphid, Aphis glycines. Loci were chosen from a closely related species (Aphis gossypii) and a more distantly related species (Aphis fabae). We found nine loci to be polymorphic among Korean and North American populations. Overall expected hete...

In this study, the orientation of two different predator species [(Coccinella septempunctata L., Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae)) to aphids [Aphis fabae Scopoli and Acyrthosiphon pisum Harris (Hemiptera: Aphididae)] was investigated. Y-type olfactometer which made glass material with one entrance exit openings used in study. Different applications were applied ends pred...

Mutualistic interactions between ant and aphid species have been the subject of considerable historical and contemporary investigations, the primary benefits being cleaning and protection for the aphids and carbohydrate-rich honeydew for the ants. Questions remained, however, as to the volatile semiochemical factor influencing this relationship. A recent study highlighted the role of bacterial ...

Life history parameters of the ladybird populations, Propylea quatuordecimpunctata (L.) (Coleoptera: Coccinellidae), collected at two locations in Iran (Karaj and Sari) were recorded on two prey species, Aphis fabae Scopoli, 1763 and Aphis gossypii Glover, 1877 (Homoptera: Aphididae). The duration of most developmental stages (egg, first, second and third instar larva...

Aphids cause considerable damage to numerous crops all over the world and insecticides are main means of controlling them, despite their detrimental impacts on human environmental health. This study assessed effectiveness parasitoid Aphidius colemani Viereck (Hymenoptera: Braconidae), a mixture predatory ladybird beetles, Hippodamia variegata Goeze, Chilocorus calvus Chiccl, Cheilomenes propinq...

Cotton leafroll dwarf virus (CLRDV) is an introduced Polerovirus (Family: Solemoviridae) of cotton, Gossypium hirsutum L., in the U.S. The only vector known to transmit this cotton aphid, Aphis gossypii Glover; however, there are seven other species aphids (Hemiptera: Aphididae) reported colonize southeastern U.S.: Protaphis middletonii (Thomas), Rhopalosiphum rufiabdominale (Sasaki), craccivor...
