Two Populations

The multicolored Asian lady beetle, Harmonia axyridis (Coleoptera: Coccinellidae), originates from South-East Asia and is now considered as an invasive species at a worldwide scale, with populations encountered in North and South America, Africa, and Europe. Several previous studies suggested that invasive populations display different behavioral and physiological traits, leading to a better fitness than native individuals. H. axyridis sex pheromone was identified recently, but only from individuals established in Europe. In this study, we compare the composition of the female sex pheromone of H. axyridis from two populations: (i) an invasive population in North America, and (ii) a native population in South-East China. We found the females originating from both populations to release in similar proportions the same five pheromonal compounds, namely β-caryophyllene, β-elemene, methyl-eugenol, α-humulene, and α-bulnesene. However, females from the North American strain release all five compounds in larger amount than the Chinese ones. Whether invasive individuals were selected during the process of invasion through their capacity to better call and find sexual partners remains to be confirmed.

The reasons for the evolution and maintenance of striking visual phenotypes are as widespread as the species that display these phenotypes. While study systems such asHeliconiusandDendrobatidaehave been well characterized and provide critical information about the evolution of these traits, a breadth of new study systems, in which the phenotype of interest can be easily manipulated and quantified, are essential for gaining a more general understanding of these specific evolutionary processes. One such model is the multicolored Asian lady beetle,Harmonia axyridis, which displays significant elytral spot and color polymorphism. Using transcriptome data from two life stages, adult and larva, we characterize the transcriptome, thereby laying a foundation for further analysis and identification of the genes responsible for the continual maintenance of spot variation inH. axyridis.

<p>The multicoloured Asian ladybeetle, <em>Harmonia </em><em>axyridis</em> (Pallas), an invasive biocontrol agent introduced in North and South America, as well as in Europe for aphid control, drastically affected assemblages of native coccinellid species, local communities and people. Although the insect is common in several European countries and it was released in Spain for aphid control in 1995, no evidence of population establishment has been reported until 2011. In the present paper, 1) we summarize the records of the invasive ladybeetle in Spain and provide numerous new mentions, and 2) we follow for the first time an overwintering aggregation from autumn to spring and characterize some individual features which allow us to determine its phenology of the establishment and spreading. The results establish clearly that: 1) <em>H. axyridis</em> is (until now) restricted to Catalonia (NE Spain) but the invading process is in progress and the insect is able to occupy different habitats; 2) the ladybeetle overwinters successfully in Spain without significant natural mortality or parasitism; 3) the form <em>succinea</em> represents 73-81% of the overwintering individuals, and 4) the invasion takes probably its origin from Southern France. The potential impact of the invasion by <em>H. axyridis</em> in Spain is discussed.</p>

"Taya" Marlon Díaz, John Conde, Pedro Félix, Sandra Ramírez, Roly Vicuña Asociación Científica de Investigación Farmacéutica - Facultad de Farmacia y Bioquímica- Universidad Nacional “San Luis Gonzaga” de Ica. DOI: https://doi.org/10.33017/RevECIPeru2012.0004/ RESUMEN El género Baccharis es una de las más importantes fuentes de productos en la medicina natural, se distribuyen en el Norte y Sur de América y en nuestro país en las zonas alto andinas, despertando el interés por su uso etnofarmacológico. La especie Baccharis tricuneata (L.f.) pers. “taya”, es usada en la medicina tradicional en la terapia antiinflamatoria en forma de emplastos. El extracto acetato de etilo se obtuvo a partir del extracto etanólico por sucesivos fraccionamientos utilizando solventes polaridad creciente. Se realizó la identificación de flavonoides en los extractos mostrando mayor presencia en el extracto de acetato de etilo. Se formuló y evaluó la actividad antiinflamatoria de una crema elaborada a partir del extracto de acetato den etilo a varias concentraciones. La evaluación farmacológica se realizó por el método de Edema Auricular Inducido por Aceite de Croton. La crema al 30% mostró actividad antiinflamatoria del 71.43%. Se atribuye a los flavonoides la actividad antiinflamatoria encontrada ya que existen reportes de su gran poder de estabilizar membranas y los radicales oxidantes. Descriptores: etnofarmacológico, Baccharis tricuneata, actividad antiinflamatoria. ABSTRACT The genus Baccharis is one of the most important sources of products in the natural medicine, are distributed in the North and South America and in our country in the high Andean areas, arousing the interest of their usage etnofarmacologico. The species Baccharis tricuneata (L. f.) Pers. "Taya", is used in traditional medicine in the antiinflammatory therapy in the form of poultices. The ethyl acetate extract was obtained from the ethanolic extract by successive fragmentations using solvents increasing polarity. It carried out the identification of flavonoids in the extracts showing greater presence in the ethyl acetate extract. It was formulated and assessed the antiinflammatory activity of an ointment prepared from the extract of ethyl acetate to various concentrations. Pharmacological evaluation was performed by the method of ear edema induced by Croton Oil. The cream to the 30% showed antiinflammatory activity of 71.43 %. It is attributed to the flavonoids the antiinflammatory activity found that there are already reports of his great power to stabilize membranes and oxidizing radicals. Keywords: ethnopharmacological, Baccharis tricuneata, anti-inflammatory activity.

The multicolored Asian lady beetle, Harmonia axyridis, is a significant pest for eastern U.S. and Ontario wine makers, but the timing of beetle infestation and its interaction with grape injury are unclear. The authors present results showing the influence of freshly injured berries on H. axyridis infestations in wine grapes, and how this relationship affects the management of H. axyridis.
