The glassy-winged sharpshooter, Homalodisca vitripennis (Germar), is an invasive pest which presents a major economic threat to grape industries in California, because it spreads a disease-causing bacterium, Xylella fastidiosa. In this note we develop a time and temperature dependent mathematical model to analyze aggregate population data for H. vitripennis from a 10-year study consisting of biweekly monitoring of H. vitripennis populations on unsprayed citrus, during which H. vitripennis decreased significantly. This model was fitted to the aggregate H. vitripennis time series data using iterative reweighted weighted least squares (IRWLS) with assumed probability distributions for certain parameter values. Results indicate that the H. vitripennis model fits the phenological and temperature data reasonably well, but the observed population decrease may possibly be attributed to factors other than the abiotic effect of temperature. A key factor responsible for this decline but not analyzed here could be biotic, for example, potentially parasitism of H. vitripennis eggs by Cosmocomoidea ashmeadi. A biological control program targeting H. vitripennis utilizing the mymarid egg parasitoid Cosmocomoidea (formerly Gonatocerus) ashmeadi (Girault) is described.

带有玻璃翅膀的神枪手，霍马洛迪斯卡·维特彭尼斯（Germar）是一种入侵性害虫，对加利福尼亚的葡萄产业构成了重大经济威胁，因为它传播了一种引起疾病的细菌，即Xylella fastidiosa。在这份说明中，我们制定了时间和温度相关的数学模型来分析人口总量数据H. vitripennis从10年的研究，包括双周监测H. vitripennis上未喷洒柑橘的人群，在这期间H. vitripennis显著下降。该模型适合于总的H. vitripennis时间序列数据，使用迭代重加权加权最小二乘（IRWLS），并针对某些参数值假设了概率分布。结果表明，H。vitripennis模型可以很好地拟合物候和温度数据，但是观察到的种群减少可能归因于温度的非生物效应以外的其他因素。负责这一下降趋势，但在这里不分析的一个关键因素可能是生物的，例如，可能寄生H. vitripennis由鸡蛋Cosmocomoidea ashmeadi。靶向生物控制程序H. vitripennis利用mymarid卵寄生Cosmocomoidea（以前Gonatocerus）ashmeadi 说明（Girault）。
