济南市郊春末夏初直翅目(Orthopteren)昆虫生态研究

本文系作者于1992年春末夏初对济南市郊直翅目昆虫群落进行调查研究的结果。讨论了直翅目昆虫成体及幼体与其选栖生境、生态习性(湿度)之间的关系及各个种的相对数量级。结果表明:春末夏初济南市郊直翅目昆虫计26种,分隶于2亚目,5总科,11科。其中以成体越冬计3种,多数种类以卵越冬,计23种;不同生境中同种直翅目昆虫幼体发育速度不一致,在济南市郊内表现为不同龄期的同一种类可同时捕到,共计8种其数量级为“极多”或“多”,可视为济南市部优势种,对其中能够侵入农田的大中型植食性种应进行必要的预报和防治。     

指环虫目单殖吸虫的行为

对小鞘指环虫、鲢指环虫和河鲈锚首虫行为的研究表明:在寄生状态下,这三种单殖吸虫的活跃性很不一样,而被剥离到清水中之后,其活动性均大大加强.纤毛幼虫孵出后即开始活跃的运动,对水流敏感且对来自宿主鱼和非宿主鱼的组织有相似的趋向反应.     

浅谈两栖类的变态

某些动物在发育过程中具有幼虫期,幼虫转变为成体要经过变态,本文重点介绍了两栖类的变态。,     

FDMRM-1脱毒菜籽饼饲养黄粉虫试验研究

用FDMRM-1生产的脱毒饼饲养黄粉虫连续三代,未发现致畸作用。脱毒饼在黄粉虫饲料中的添加量不受限制,可依饲料配比确定。这种养殖方法可降低饲料成本,又可提高饲料营养,加快幼虫生长速度,增加产卵量,明显地提高养虫效益。     

Nutrient composition, mineral content and the solubility of the proteins of palm weevil, Rhynchophorus phoenicis f. （Coleoptera： Curculionidae）

Adult (ADS) and larva stages of palm weevil Rhynchophorus phoenicis were analyzed for their nutritional potentials using proximate and mineral contents as indices. The early larva stage (ELS) contains the highest moisture content of 11.94% while ADS has the least value of 4.79%. The late larva stage (LLS) has the highest protein content of 10.51% while ADS contains 8.43%. Ash content is highest in ELS with a value of 2.37% and lowest in ADS with a value of 1.43%. ELS and LLS have the highest (22.14%) and lowest (17.22%) fibre contents respectively. The values of potassium, magnesium and iron in ELS were (455.00±21.21), (60.69±2.57) and (6.50±3.40) mg/kg while LLS recorded (457.50±10.61), (43.52±1.37) and (6.00±1.10) mg/kg and ADS recorded (372.50±24.75), (53.31±1.88) and (22.90±3.70) mg/kg. Chromium, phosphorus, nickel, calcium, lead, man- ganese and zinc were also detected. Copper was not detected in any of the samples. In all the developmental stages the protein solubilities were pH dependent with the minimum protein solubilities occurring at acidic pH while the maximum protein solu- bilities occurred at alkaline pH.     

中华虎凤蝶生物学特性的研究

中华虎风蝶是我国的特有种（国家２类保护动物）．一年一代,以蛹越冬．幼虫期４～５月,蛹期５     

周氏虎凤蝶不同于中华虎凤蝶

通过周氏虎凤蝶（Luehdorfia choui）的深入观察和人工饲养（共养育成功31只）,弄清了周氏虎凤蝶各个虫态的特征和经历时间及个体发育的规律.通过形态特征（卵、幼虫、蛹、成虫）和其他特征的研究对比,进一步弄清了周氏虎凤蝶和近缘种——中华虎凤蝶（Luehdorfia chinensis）的区别,证明二者是两种不同的虎凤蝶.这对于鉴别和研究蝴蝶、保护和合理利用虎凤蝶资源有极其重要的意义和价值.
