【摘要】 腐食酪螨Tyrophngus Putrecsentiae (Schrunk)是世界上重要的储藏物螨类之一,也是我国最重要的储藏物害螨。本文在27℃,65％rh.75％rh.95％rh.和30℃,75％rh.95％rh.条件下对腐食酪螨的生活史作了研究。该螨的生活周期经过卵、幼螨、第一若螨、第三若螨和成螨。没有休眠体时期,但在进入第一若螨、第三若螨及成螨前均有一短暂的静息期。该螨发育的最适条件为30℃、75％rh,此时完成一代约需9.2天,其发育的高温极限是35℃。本文描述了该螨各发育阶段的形态。更多还原

【Abstract】 Tyrophagus putrecsentiae ( Schrank ) is one of the most important species of stored product mites in the world, and the most important species in China as well. A study on the life history of T. putrecsentiae (Schrank ) was made at a series of temperatures and relative humidities ( 65, 75 and95% rh. at 27℃ 75 and 95% rh. at 30℃ . The development of this spec-ies of mites can be divided into the following stages : the egg, sixleggedlarva, the protonymph, the tritonymph and the adult. There is no hypops stage, but a resting period exists at the end of the nymphal stages. The optimum conditions for development of this mite were found to be 30() and 75% rh. At these conditions development from egg to adult took about 9.2 days. If temperature is over 35(), the mites can’t develop. All .the stages of this specis of mites are described in this paper.更多还原
