A new species of Metopiinae, Trieces etuokensis Sheng, sp. n., is described and illustrated. Specimens were reared from two species of Lepidoptera: Bazaria turensis (Ragonot, 1887) (Pyralidae) from Balong, Dulan, Qinghai Province, and an unidentified psychid (Psychidae) from Mukainor, Etuoke, Inner Mongolia Autonomous Region, China. The new species is characterized by a yellow face and clypeus,...

Shelter-building behavior by caterpillars provides a mechanism of defense against predators, microenvironment enhancement, and in some cases nutritional benefits. This study provides a detailed description of the life cycle and shelter-building process of caterpillars, and identifies constraints and factors influencing this adaptive behavior in Lepidomys n. sp. near proclea Druce (Pyralidae: Ch...

Sugarcane, Saccharum officinarum L., is one of the most economically important crop of Thailand. It is the main source of sucrose, and is used in sugar and alcohol production. Insect pest complex is the most important limiting factor in sugarcane production. Among the sugarcane insect pest complexes, the sugarcane moth borers complex is considered most important. Chilo infuscatellus Snellen, Ch...

Neural sites that interact with the suprachiasmatic nuclei (SCN) to generate rhythms of unrestricted feeding remain unknown. We used the targeted toxin, leptin conjugated to saporin (Lep-SAP), to examine the importance of leptin receptor-B (LepR-B)-expressing neurons in the arcuate nucleus (Arc) for generation of circadian feeding rhythms. Rats given Arc Lep-SAP injections were initially hyperp...

We review the results of the Standard Model Higgs boson search at LEP. An emphasis is put on revealing the details behind the statistical procedure developed by the LEP Higgs working group. The procedure is explained using a toy model which allows the reader to estimate the significance of the experimental observation which led at the time to a scientific debate on whether LEP has observed a 11...

Wavelength (nm) 1995), analysis of sugar related products (Schaffler et al., 1993) and predicting varietal resistance to the stalk borer Eldana saccharina Walker (Lepidoptera: Pyralidae) (Rutherford et al., 1993). This paper is a summary of some past and current research in South Africa, as well as indicating potential new applications. Comparison of NIR spectra for a range of products tested a...

The aim of this study was to analyze LEP and DGAT1 gene polymorphisms in 3 Nelore lines selected for growth and to evaluate their effects on growth and carcass traits. Traits analyzed were birth, weaning, and yearling weight, rump height, LM area, backfat thickness, and rump fat thickness obtained by ultrasound. Two SNP in the LEP gene [LEP 1620(A/G) and LEP 305(T/C)] and the K232A mutation in ...

Measurements made by the four LEP experiments of electroweak parameters and the strong couphng constant are presented. These are used in an overaU Standard Model fit and a constraint on the mass of the top quark is derived. 1. Precision Measurements of Electroweak Parameters During 1989, 1990 and 1991 the four main experiments at the LEP e+ecollider (ALEPH, DELPHI, L3 and OPAL) have recorded da...

Obesity is a public health problem that increases the risk of metabolic disease, infertility, and other chronic health problems. The present study aimed to develop a new rat model for sex hormone disorder with overweight and Ca loss by intramuscular injection of exogenous leptin (LEP). Thirty female Sprague-Dawley (SD) rats (40 days old) were injected thrice intramuscularly with LEP or keyhole ...

Variants in leptin gene (LEP) have been implicated in the pathogenesis of obesity. The relationship between LEP G-2548A polymorphism and obesity-related traits was evaluated in a sample of Brazilian women (n = 228) who were randomly selected from two clinical centers in Sao Paulo city. Blood samples were collected for DNA extraction, plasma leptin and serum lipids measurements. LEP G-2548A geno...
