Effect of relative humidity conditions on responsiveness of European corn borer (Ostrinia nubilalis) males to female sex pheromone in a wind tunnel

The responsiveness pf 3-day-old European corn borer males to three concentrations of 973 ZE 11-tetradecenyl acetate, the female sex pheromone, was studied over a range of relative humidities (43–100%) in a wind tunnel. The proportion of males taking flight and reaching the source decreased, while the proportion exhibiting in-flight arrestment of upwind progress increased under high humidity conditions at all three concentrations of pheromone tested. The relationships between relative humidity and these behaviors were best described by polynomial equations.     

(+)-cis-3-Pinen-2-ol: Attractant for male cerambycid beetle,Monochamus alternatus hope

A monoterpene alcohol was isolated from paraquat-induced lightwood in pines and identified as (+)-cis-3-pinen-2-ol [(+)-3]. More than a certain amount of (+)-3 induced a laboratory flight response by the male cerambycid beetle,Monochamus altematus Hope, but (+)-3 stimulated no response by the female at any dose level tested. Compound (+)-3 was not detected in trunks of sound pines.     

Marking pheromones ofAlpinobombus males

The male marking pheromone blends which emanate from the cephalic part of the labial gland, have been analyzed in four species of the bumble bee genusAlpinobombus, viz.,A. alpinus,A. balteatus, A. hyperboreus, andA. polaris, by combined capillary gas chromatography, mass spectrometry, and thin-layer chromatography. In all, 36 specimens were analyzed.A. alpinus andA. polaris, which are similar morphologically, both showed an acetogenic composition of the pheromone blend. The dominant compound inA. alpinus proved to be a hexadecenol, whereasA. polaris had a hexadecadienol and a hexadecenol in the proportions 52 as major components.A. balteatus andA. hyperboreus, another species pair as regards their morphology, differed more in their chemical makeup. Both mevalogenins and acetogenins were found in their marking secretions.A. balteatus is unique among all other male bumble bee species analyzed, 29 in total, by having C₁₂- and C₁₄-butyrates in the secretion, which dominated together with tetradecyl acetate and geranylcitronellol. InA. hyperboreus the main marking compounds are an octadecenol and 2,3-dihydro-6-trans-farnesol. This species also contains citronellol and geranylcitronellol.Hymenoptera, Apoidea, Bombinae.     

The MMPI critical items: how well do they work?

Examined the theoretical foundation and empirical performance of 2 sets of "critical items" that are a common feature of most automated MMPI interpretations. These items purportedly alert the clinician to serious pathology and operate as a scale of general maladjustment. Critical items resulted in numerous misclassifications when used as a scale of adjustment with 43% of 1,023 male psychiatric patients and 95% of 1,045 normal male job applicants responding in the deviant direction on 5 or fewer items. The critical items consist mainly of F -scale items and duplicate the information communicated by this scale. The extremely deviant nature of the critical items makes them capable of only reflecting crises of psychotic proportions. When face-valid critical items were compared to clinical data, 70-76% resulted in empirically valid behavior samples. Invalid critical items are listed. It is concluded that MMPI critical items are inadequate for screening purposes. (20 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

第28届奥运会足球预选赛中、韩阵容组合及技术运用情况的对比分析

采用统计、对比分析法,对第28届奥运会足球预选赛亚洲区12强赛中、韩男子足球队阵容组合及技术运用情况进行对比分析.研究表明：中国国奥队虽具备良好的身体条件,但在年轻队伍的梯队建设、对抗中传球和抢截球技术运用能力、对抗中有效地完成攻防技术的稳定性等诸方面存在着明显的不足.     

文冠果雌雄花发育过程形态结构比较

文冠果(Xanthoceras sorbifolia Bunge)是重要的生物能源植物.文冠果花一般可分为两种类型,一种是雄蕊败育的雌花,一种是雌蕊败育的雄花.但关于文冠果雌雄花败育过程的研究至今尚无报道.本文用数码相机和扫描电子显微镜观察并比较了文冠果雌雄花发育过程的结构变化.结果显示:(1)性别分化前期,即4月中旬两种类型花在形态上无明显差别;(2)性别分化中期,即4月下旬,雌雄花分化开始表现明显差别,雌花雄蕊逐渐退化,而雌蕊3心皮逐渐愈合发育形成花柱、柱头和子房,花柱由短圆柱形发育成三棱形,再逐渐发育成圆柱形;雄花心皮不能发育成明显的花柱、柱头和子房,3心皮独立存在,逐渐退化;(3)性别分化后期,即5月初,雌花雄蕊花丝停止伸长,花药不饱满,雌蕊花柱继续伸长至雄蕊两倍,柱头3基瓣外翻,乳突状细胞密生且逐渐发育成长圆柱形;雄花内圈4枚雄蕊花丝继续伸长,而外圈4枚雄蕊花丝先短于内圈4枚雄蕊,形成四强雄蕊,后伸长至一致,随后花药开裂散粉,而雌蕊完全干缩至雄蕊内侧基部.综上所述,文冠果两种类型花的形成是早期花芽分化完全的两性花发育到后期,由其中一种性器官退化的结果.
