| 摘要: |
| 【目的】对拟黑多刺蚁发育生活史及成虫不同品级形态与分工进行详细观察描述，并对幼虫龄期划分进行研究。【方法】在自然光照、温度(26±3) ℃、相对湿度45%~55%的条件下，观察拟黑多刺蚁发育生活史及成虫不同品级形态与分工；根据幼虫体长、头宽、体质量、消化道长，以及幼虫形态特征等数据，并结合戴氏定律，对幼虫龄期进行划分。【结果】在试验条件下，拟黑多刺蚁卵发育期为(24.5±3.5) d、幼虫发育期为(25.0±5.5) d、蛹发育期为(20.5±5.5) d。拟黑多刺蚁幼虫期可分为4个龄期，其中1龄幼虫发育时间为(4.5±1.5) d，2龄幼虫为(5.5±1.5) d，3龄幼虫为(7.0±1.0) d，4龄幼虫为(8.0±1.5) d。【结论】描述了拟黑多刺蚁不同时期的品级分工和形态，明确了拟黑多刺蚁幼虫时期的生物学特性。 |

| Abstract: |
| 【Objective】This paper observed and described life cycle of P.vicina and the shapes and division of labor of adults.The growth and development stages of larva were also differentiated.【Method】Under natural sunlight,temperature of （26±3） ℃,and relative humidity of 45%－55%,life cycle of P.vicina,and shapes and labor division of adults were observed.The morphological characteristics,body length,head width,weight,and digestive tract length of larvae were measured for division of larval development.【Result】In the environment conditions of this study,egg development time was (24.5±3.5) days,larval development period was (25.0±5.5) days,and pupa development period was (20.5±5.5) days.P.vicina larvae stage can be divided into four instars,the first instar was (4.5±1.5) days,the second instar was (5.5±1.5) days,the third instar was (7.0±1.0) days,and the fourth instar was (8.0±1.5) days.【Conclusion】This study described the grade division and morphology of Polyrhachis vicina Roger at different periods. |
