Chromatin organization in the holocentric chromosomes of the aphid Brevicoryne brassicae has been investigated at a cytological level after C-banding, NOR, Giemsa, DAPI and CMA3 staining. C-banding technique showed the presence of heterochromatic bands on both telomeres of the two X chromosomes, whereas only the longest pair of autosomes show distinct intercalary C-positive bands. Moreover, sil...

La supresión de moléculas ácido ribonucleico mensajero (ARNm) mediante ARN interferente (ARNi) se ha propuesto como método control insectos plagas. El ARNi impide el desarrollo morfológico y funcional los considera altamente específico. En este estudio buscaron receptores insulina (InR) en Brevicoryne brassicae L. (Hemiptera: Aphididae) a partir del ARNm pulgones, primer paso para diseño poster...

Plants are part of biodiverse communities and frequently suffer from attack by multiple herbivorous insects. Plant responses to these herbivores are specific for insect feeding guilds: aphids and caterpillars induce different plant phenotypes. Moreover, plants respond differentially to single or dual herbivory, which may cascade into a chain of interactions in terms of resistance to other commu...

Studies on chemical ecology of host plant selection by herbivores were largely carried out to explain the diversity of secondary plant chemicals and host specialisation of herbivores. The glucosinolate – isothiocyanate system in Brassicaceae plants was considered as a plant defence and was known to influence the feeding behaviour of phytophagous insects such as the cabbage aphid, Brevicoryne br...
