【解析】昆虫的完全变态发育包括：受精卵、幼虫、蛹和成虫，而不完全变态发育包括：受精卵、幼虫、成虫，据此答题．利用生物来防治病虫害．常用的方法有以虫治虫、以鸟治虫和以菌治虫等．生物防治就是利用一种生物对付另外一种生物的方法．生物防治，大致可以分为以虫治虫、以鸟治虫和以菌治虫三大类；它是降低杂草和害虫等有害生物种群密度的一种方法．【答案】解：（1）通过信息：赤眼蜂的雌蜂专门寻找害虫虫卵，产卵其中．可知生殖方式是有性生殖，卵生．（2）赤眼蜂的生殖方式是完全变态发育，在个体发育中，经过卵、幼虫、蛹和成虫等4个时期的叫完全变态发育．完全变态发育的幼虫与成虫在形态构造和生活习性上明显不同，差异很大．如蝶、蚊、蝇、菜粉蝶、蜜蜂，蚕等．（3）生物防治就是利用生物来防治病虫害．常用的方法有以虫治虫、以鸟治虫和以菌治虫等．它是降低杂草和害虫等有害生物种群密度的一种方法．它利用了生物物种间的相互关系，以一种或一类生物抑制另一种或另一类生物．它的最大优点是不污染环境，成本低，是农药等非生物防治病虫害方法所不能比的．故答案为：（1）有性生殖，卵生（2）卵、幼虫、蛹、成虫四个时期，属于完全变态发育．（3）成本低，还可以减少因使用农药对环境的污染．【点评】解答此类题目的关键是理解掌握昆虫的发育过程以及生物防治的优点．

保护非物质文化遗产的意义一、认识历史的需要与物质类文化遗产一样，非物质文化遗产也同样具有重要的历史认识价值。所不同的是，物质类文化遗产是以物化的固态的方式来展现其历史认识价值，而非物质文化遗产主要是通过活态传承的方式来实现其历史认识价值和意义。可以说，任何一种传统文化事项都具有历史认识价值，都会从不同的角度给人类以启迪。二、文化创新的需要人类社会要发展，就需要不断创新。创新的源泉主要来自两个方面：一是向国外学习，从异域文化中汲取营养；二是向传统学习，从本土文化中汲取精华。非物质文化遗产在文化创新、艺术创新、科学创新各个新领域中都将发挥重要作用。保护非物质文化遗产，不仅仅是认识历史的需要，同时也是创建新文学、新艺术、新技术、新工艺的需要。三、保护文化多样性的需要正如《保护和促进文化表现形式多样性公约》所说，文化“多样性创造了一个多姿多彩的世界，它使人类有了更多的选择，得以提高自己的能力和形成价值观，并因此成为各社区、各民族和各国可持续发展的一股主要推动力，以及在民主、宽容、社会公正、各民族和各文化间相互尊重的环境中繁荣发展起来的文化多样性对于地方、国家和国际层面的和平与安全是不可或缺的”。人类非物文化遗产本身就是文化多样性的表现与体现，一定程度上说，保护非物质文化遗产也就是保护人类文化的多样性。四、重建社会秩序的需要历史经验告诉我们，任何一个社会群体的发展都需要凝聚力，而一个群体或者民族的凝聚力最根本最重要的是来自于文化认同。我们今天所进行的非物质文化遗产保护事业，除了在保护中国千百年来积淀起来的各种传统艺术形式方面应发挥重要作用外，还应充分考虑到这些传统表现形式在传承中华文明，特别是传承中华道德文明、增强民族自信心和民族凝聚力方面将发挥重要的作用。
