Ecol. We observed and quantified the responses of a number of clones and life stages to varying levels of starvation, in the form of increasingly desiccated Vica faba L. plants (receiving 50, 25, or 10 mL every second day) or a complete absence of host plant. Dicke, M., Van Loon, J. J. The other 8 constitute host specialized races and likely belong to the same species. 50:2571–2575. Caractères spécifiques et distinction d'espèces semblables. It transmits the persistent viruses Pea enation mosaic virus-1 (PEMV) and Pea seed-borne mosaic virus (PSbMV) ( Blackman and Eastop, 2000 ). Endogenous melatonin in pea aphids was measured by … Insect Mol Biol. The image above shows the brownish, unevenly-swollen cadaver of an Entomophthora-infected Acyrthosiphon pisum: note the hyphae anchoring its underside to the leaf. Front Physiol. To clarify the aphicidal action, avermectin was selected as a positive control, and matrine, ... (Acyrthosiphon pisum). Damage & Control: Acyrthosiphon pisum is considered one of the 14 aphid species of most agricultural importance (Blackman & Eastop, 2007). Kovats, E. S. 1988. The latter is thought to be expressed by a −1 translational frameshift. Life cycle of the pea aphid, Acyrthosiphon pisum. For example, through observation and experiments, Wei et al. In contrast, virus disease incidence was extremely high on lentils (70.8%), the most common being PSbMV (52.1%) followed by the luteoviruses (10.8%), Broad bean mottle virus (BBMV) (7.5%) and BYMV (0.4%).Turkmen et al. Le puceron vert du pois (Acyrthosiphon pisum) est un très petit insecte appartenant à l'ordre des homoptères et à la famille des aphididés.Il parasite de nombreuses plantes cultivées de la famille des légumineuses telles que le pois et le haricot. (B) RSL sequences were aligned with MAFFT using the E-INS-i strategy and adjusted manually. It transmits the persistent viruses Pea enation mosaic virus-1 (PEMV) and Pea seed-borne mosaic virus (PSbMV) (Blackman and Eastop, 2000). The period from oviposition to pupation was independent of host size at parasitization. Today A. pisum is not a significant problem in alfalfa. By continuing you agree to the use of cookies. De Biasio F, Riviello L, Bruno D, Grimaldi A, Congiu T, Sun YF, Falabella P. Insect Sci. Figure 10.2. (2005) showed that the exposure to alarm pheromone also induced aphids to give birth to winged dispersal morphs that leave their host plants. Additionally, if we could reduce the simple sugar load and moisture level of the cockroach's body by using dry food instead of moist, fresh fruits and vegetables for feeding cockroaches, the mould load and the presence of medically significant strains would be significantly suppressed., DOI:, Over 10 million scientific documents at your fingertips, Not logged in Les adultes résultants sont tous de sexe féminin, et se reproduisent continuellement par parthénogénèse, c'est-à-dire sans avoir été préalablement fécondées. In the USA several Aphidius parasitoid have been found attacking Acyrthosiphon pisum on alfalfa. Plant Physiol. The gut microorganisms of B. germanica play a vital role in defence against external invasion especially entomopathogenic fungi and promoting the function of immune system (Herren and Lemaitre, 2011; Riparbelli et al., 2012). Acyrthosiphon loti which does not have the antennal joints darkened). CAS  Acyrthosiphon pisum is a major pest of peas and alfalfa, partly because of direct feeding damage and partly because of virus transmission. A., and Dicke, M. 2008. CAS  The pea aphid is regarded as a model species for studying a range of biological phenomena including polymorphisms, insect -bacterial symbioses, the genetics of adaptation and plant virus transmission.
