2003年上半年我国染料、有机颜料生产及进出口情况浅析（一）

20 0 2年我国染料及有机颜料生产和进出口数量达到历史最好水平 ,2 0 0 3年上半年虽然经受了SARS的影响 ,但我国染料及有机颜料工业仍然取得了稳定增长的成绩。上半年染料产量总计 19 5 9万t,同比增长 2 4 7%;颜料产量为 4 30万t,同比增长 2 1 6 9%。上半年出口增长幅度减缓 ,染料出口总量为 9 92万t,同比增长 3 1%;有机颜料出口为 4 2万t,同比增长 3 1%。进口基本稳定 ,上半年染料进口量为 3 2 5万t,同比增长 9 1%;有机颜料进口为1 6 9万t,同比增长为 11 5 %。总之 ,上半年主要经济指标完成情况良好 ,进出口数量和经济效益继续保持稳定增长。但染料和纺织品的生产与出口都遇到一定的困难 ,纺织品出口又直接影响染料的内销市场 ,由于内外市场的变化 ,使染料生产和进出口的增长幅度减缓。

A novel attractant for Mexican fruit fly,Anastrepha ludens,from fermented host fruit

Chemicals from fermented chapote fruit were identified and evaluated as attractants for hungry adult Mexican fruit flies in laboratory and greenhouse bioassays. Twenty-eight chemicals identified from an attractive gas-chromatography fraction were as attractive as a chapote volatiles extract (CV) when mixed in the same amounts found in CV. Sixteen of the chemicals were slightly attractive to flies when tested individually. A mixture containing 15 of the chemicals by design and the 16th as an impurity, in arbitrary concentrations, was at least as attractive as the original CV. In a series of experiments, the number of chemicals was reduced to three by elimination of unnecessary components. The three-component mixture retained the attractiveness of the 15-component mixture. The three chemicals were 1,8-cineole, ethyl hexanoate, and hexanol (CEH). Attractiveness of the three-chemical mixture was equal to the sum of the attractiveness of the three individual components, suggesting that each chemical binds to a different receptor type that independently elicits partial attraction behavior. Optimal ratios were 1011 of the three chemicals, respectively. Optimal test quantities ranged between 0.4–4g of 1,8-cineole and 40–400 ng each of ethyl hexanoate and hexanol applied to filter paper in the laboratory bioassays. A neat 1011 mixture of the chemicals was 1.8 times more attractive than aqueous solutions ofTorula dried yeast and borax to starved 2-day-old flies when the lures were tested in competing McPhail traps in a large greenhouse cage.Diptera: Tephritidae.     

Acquired Predator Recognition by Fathead Minnows: Influence of Habitat Characteristics on Survival

In this study we conditioned fathead minnows (Pimephales promelas) to recognize the odor of a perch (Perca flavescens) by exposing them to perch odor coupled with minnow alarm cue. We then staged encounters between the predator and prey in order to assess whether the predator odor training had any effect on survival of the prey. We tested for a survival effect in the presence and absence of shelter. Our results indicate that fish trained with alarm signals to recognize predators gained a survival benefit during staged encounters with a predator and that habitat characteristics influenced the survival of conditioned fish.
