Effects of diapause and host species on some morphometric characters inTrichogramma (Hym.: Trichogrammatidae)

Adult morphology ofTrichogramma is modified by environmental conditions during the preimaginal development. For instance, the low temperatures inducing diapause cause a decrease of the ratio length of longest seta on male flagellum/width of flagellum inT. evanescens. The species of the host also influences numerous body ratios. So, in females, the development of tibiae with regard to wings is more important withScotia ipsilon than withGalleria mellonella. These results confirm the necessity of performing comparative morphological studies on individuals reared in the same conditions.     

中国林蛙卵油对焦虑大鼠运动能力影响研究

目的:研究中国林蛙卵油对焦虑大鼠运动能力及体重摄食量的影响;方法:通过焦虑造模,对50只SD雄性大鼠进行随机分5组,即安静色油组、安静卵油组、模型色油组、模型卵油组、模型安定组,通过药物干预测定相应指标进行分析研究;结果:发现中国林蛙卵油可以明显提高大鼠运动能力,提高大鼠饮食量及体重;结论:中国林蛙卵油在抗疲劳及抗焦虑方面有积极作用.     

基于EPR模型的北部湾二长棘鲷渔业管理研究

运用单位补充量产卵量（egg production per recruit,EPR）模型评价了北部湾二长棘鲷资源状况。推测在当前捕捞死亡系数下,EPR为5 963.51粒.尾-1,相当于未开发状态下的15.49%,表明该渔业已处于过度捕捞状态。管理策略模拟分析发现实施禁渔期和改变开捕体长,都可使EPR得到提高。取得相同资源管理目标时,EPR模型估算的捕捞死亡系数明显高于单位补充量亲体量（spawner biomass per recruit,SBR）模型。建议可将F20%EPR作为北部湾二长棘鲷渔业管理的限制生物学参考点。若要到达该目标,相关捕捞努力量需削减15.53%或者将开捕年龄延长到1a。     

需要层次理论对高校国防教育的启示

国防教育与人的需要有着密切的联系。马斯洛的需要层次论揭示了一般人在通常情况下的需要与行为规律,对高校国防教育具有重要的启示作用。需要的层次性、多样性、发展性和矛盾性要求高校国防教育的开展要有的放矢、与时俱进、科学有序。     

Pre-ovipositional and ovipositional behaviour of Trichouropoda ovalis (C.L. Koch) and Uroobovella marginata (C.L. Koch) (Parasitiformes: Uropodina: Trematuridae,Urodinychidae) with notes on egg incubation and hatching behaviour

Egg deposition by the soil mites Trichouropoda (= Oodinychus) ovalis (C.L. Koch and Uroobovella (= Fuscuropoda) marginata (C.L. Koch), egg incubation and hatching behaviour were observed using continuous video-monitoring. The oviposition in both species was found to consist of three distinct phases. In Phase 1, both species engage in pre-ovipositional activity prior to the egg being extruded from the genital opening. Phase 1 lasted approximately 7.5 minutes in T. ovalis and about 6 minutes in U. marginata. Phase 2 involved egg deposition and lasted approximately 2.5 times longer in T. ovalis (88 seconds) than in U. marginata. Egg covering occurs in Phase 3, and in both species lasts about 25 minutes. Incubation time in U. marginata (137 hours) was approximately 30% shorter compared to that of T. ovalis, while the hatching time was 2 times longer (150 min) in the latter species.
