Penyakit bercak bercincin pada pepaya yang disebabkan oleh Papaya ringspot virus (PRSV) dilaporkan sudah menyebar luas di Indonesia. Pemencaran penyakit ini diketahui terjadi melalui bibit tanaman terinfeksi dan serangga vektor kutudaun. Penelitian dilakukan untuk menguji efisiensi penularan PRSV dua spesies kutudaun, yaitu Aphis gossypii Myzus persicae membuktikan bahwa tidak dapat ditularkan ...

The peach–potato aphid, Myzus persicae (Sulzer), is one of the most important pests economic crops. It damages plant directly by consuming nutrients and water indirectly transmitting viruses. This pest has unenviable title having resistance to more insecticides than any other herbivorous insect pest. Due development its chemical pesticides, it necessary find control options. Consequently, incre...

Understanding the dynamics of wolf-dog hybridization and delineating evidence-based conservation strategies requires information on the spatial extent of wolf-dog hybridization in real-time, which remains largely unknown. We collected 332 wolf-like scats over ca. 5,000km2 in the NW Iberian Peninsula to evaluate wolf-dog hybridization at population level in a single breeding/pup-rearing season. ...

Wolf control to reduce cattle depredation is an important issue to ecology and agriculture in the United States. Two recent papers use the same dataset having wolf population characteristics and cattle depredation, but come to opposing conclusions concerning the link between wolf control and cattle depredation. Our paper aims to resolve this issue by using the same dataset and developing a mode...

For a further examination and elaboration of our simple charge disproportionation model for Fe4+-oxides, 2~e" + Fe3+ + Fe5+, two series of solid solutions Cal-xSrxFe03 and Srl-xLaxFe03 with the perovskite structure have been studied. The Msssbauer spectrum of Sro.sLao.sFeO3 at 4 K clearly indicates the disproportionation. For both series of oxides, the disproportionation seems to set in at the ...

Let X be a complete noncompact Riemannian manifold with Ricci curvature and Sobolev radius (see §6 for the definition) bounded from below and Y a complete Riemannian manifold with nonpositive sectional curvature. We shall study some situations where a smooth map f : X → Y can be deformed continuously into a harmonic map, using a naturally defined flow. The flow used here is not the usual harmon...

The genomic sequence of a new icosahedral DNA virus infecting Myzus persicae has been determined. Analysis of 5499 nt of the viral genome revealed five open reading frames (ORFs) evenly distributed in the 5' half of both DNA strands. Three ORFs (ORF1-3) share the same strand, while two other ORFs (ORF4 and ORF5) are detected in the complementary sequence. The overall genomic organization is sim...
