摘要
对泰安市1 320头异色瓢虫越冬成虫进行了观察研究,共发现表现型150种,其中未被记录的20种。按表现型将其分为4种类型:黄底黑斑、橘红底黑斑、黑底红斑和黑底黄斑,其种类数分别为64、67、11和8,各类型数目占调查总数的比例分别为39.24%、30.83%、26.14%和3.79%。黄底黑斑和橘红底黑斑型以十九斑变型最多,黑底红斑和黑底黄斑型以显明变型居多。对各斑点出现频率统计结果表明,斑点1/2在雄虫出现的频率约为雌虫的1/4,斑点9约为雌虫的1/2,其余各斑点雌虫均高于雄虫。首次对斑点和联斑不对称的异色瓢虫进行了命名,优化了记号命名法。
Overwintering adults of 1 320 Harmonia axyridis（ Pallas） in Taian City were investigated. A total of 150 phenotypes were found,among which 20 phenotypes were not recorded previously. According to the phenotype,they were divided into four types,including black spots on yellow background,black spots on orange background,red spots on black background and yellow spots on black background,and their species number were 64,67,11 and 8 respectively. The number of each type occupied the total number of 39. 24%,30. 83%,26. 14% and 3. 79% respectively. The 19-spot was the most common phenotype in the type of black spots on yellow background and black spots on orange background,and spectabilis was the most common phenotype in the black background type. The frequency of 1/2-spot appeared in males was about a quarter of that in female,while that of the 9-spot was a half. The frequencies of the other spots appeared in female were all higher than those in male. The spots and Harmonia axyridis with connected spots which had different number or asymmetric position were named for the first time in this paper,and the mark nomenclature was optimized.
