Polygodial (1) and its derivatives acetal 2 (propylene) and 3 (ethylene) were prepared and their antifeedant activity and toxic effects evaluated on several insect species with different feeding ecologies (Spodoptera littoralis, Leptinotarsa decemlineata, Myzus persicae and Rhopalosiphum padi) along with that of polygonone (4). We also tested their selective cytotoxic effects on insect-derived ...

The tobacco-feeding race of Myzus persicae (Sulzer), formerly known as M. nicotianae Blackman, was introduced into Chile during the last decade. In order to evaluate the genetic diversity and insecticide resistance status of Chilean tobacco aphid populations, a field survey was conducted in 35 tobacco fields covering a 300 km latitudinal survey. The populations sampled were characterized using ...

1. Phenotypic diversity is the fuel that powers evolution. 2. Asexual organisms rely on mutation whereas sexual organisms combine mutation with recombination. 3. Few organisms provide examples of species that are both sexual and asexual, but aphids do. 4. To examine evolution on perceptible timescales requires strong evolutionary forces and, as Darwin noted, agricultural practices provide stron...

The objective of the present study was to investigate whether nuclear transfer of postmortem wolf somatic cells into enucleated dog oocytes, is a feasible method to produce a cloned wolf. In vivo-matured oocytes (from domestic dogs) were enucleated and fused with somatic cells derived from culture of tissue obtained from a male gray wolf 6h after death. The reconstructed embryos were activated ...

We consider the Slepian-Wolf code design based on LDPC (low-density parity-check) coset codes. We derive the density evolution formula for the Slepian-Wolf coding, equipped with a concentration theorem. An intimate connection between the Slepian-Wolf coding and channel coding is established. Specifically we show that, under density evolution, each Slepian-Wolf source coding problem is equivalen...

A simile is an expression that indicates one has something in common with others character, either overtly or covertly, by comparing it the furniture. In Quran juz 27 there are various types of similes. Al-Qur'an Juz 27, 4 cases: what sentences have elements components and two ends similes 27. The objectives need to achieve this research find containing simile/tasbeeh know understand two-ended ...

The terrorism threat is multifaceted and ever-present; this as a result of terrorism taking on all forms including Islamic, non-Islamic, foreign and domestic. After 9/11, the federal government focused on jihadists and government resources were focused on engaging foreign jihadists allowing a resurgence of non-Islamic domestic terrorism including the lone wolf terrorist (LWT). The problem is th...
