Seasonal abundance of the strawberry aphid complex under different agronomic practices in the outskirts of La Plata, Argentina was studied on strawberry, Fragaria x ananassa Duchesne (Rosales: Rosaceae). Aphid densities were low in strawberry fields in which insecticides and fungicides were used. In addition to Aphis gossypii, Aphis fabae, Mysus persicae and Macrosiphum euphorbiae, the aphid, C...
Sieve tubes serve as transport conduits for photo-assimilates and other resources in angiosperms and are profitable targets for piercing-sucking insects such as aphids. Sieve-tube sap also contains significant amounts of proteins with diverse functions, for example in signalling, metabolism, and defence. The identification of salivary proteases in Acyrthosiphon pisum led to the hypothesis that ...
Facultative endosymbionts can induce benefits and costs to their aphid hosts. In the pea aphid, Acyrthosiphon pisum (Harris) (Hemiptera: Aphididae), infection with ?-proteobacterium Hamiltonella defensa Moran et al. confer resistance against parasitoids, but may also reduce frequency of aggressive escape behaviours exhibited in response predators. potato aphids, Macrosiphum euphorbiae (Thomas) ...

شته ها از مهم ترین آفات گیاهی کشور هستند که هر سال خسارات قابل توجهی را به محصولات کشاورزی وارد می کنند. این آفات باعث کاهش میزان فتوسنتز، کاهش رشد جوانه ها و درنهایت باعث کاهش کیفیت و کمیت محصول می شوند. زنبورهای پارازیتوئید زیرخانواده ی aphidiinae (braconidae: aphidiinae) و هم چنین خانواده ی aphelinidae از مهم ترین دشمنان طبیعی شته ها محسوب می شوند. جثه ی ریز آن ها مانعی جهت شناسایی، تعیین جا...
The western Palaearctic species of the hawkmoth genus Hyles (Lepidoptera: Sphingidae) have long been subject molecular phylogenetic research. However, much less attention has paid to taxa inhabiting central and eastern Palaearctic, particularly Central Asia, where almost 50% diversity occurs. Yet, many taxonomic conundrums hinder a proper assessment true in these moths. One still unresolved gro...
Ethylene response factors (ERFs) comprise a large family of transcription factors that regulate numerous biological processes including growth, development, and response to environmental stresses. Here, we report that Pti5, an ERF in tomato [Solanum lycopersicum (Linnaeus)] was transcriptionally upregulated in response to the potato aphid Macrosiphum euphorbiae (Thomas), and contributed to plan...
A recently synthesized kairomone blend, based on the volatiles produced by potato (Solanum spp.) plants, has been demonstrated to be attractive to both adult and larval stages of the Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae). It was subsequently formulated in a viscous inert carrier for Þeld applications and showed potential for aggregating beetles in t...
