Kdr resistance and determination of frequences of kdr gene in house fly field population L1014F is the most common amino acid substitution in the kdr allele. The frequency of the L1014F kdr allele was determined by the method of PASA in fourteen field populations of houseflies with resistance factors at LD〓 for pyrethrin/ piperonyl butoxide and bioresmethrin/piperonyl butoxide from 4 to 29 and 2 to 98, respectively.

We made the light absorption coefficient measurement system with Nuclepore filter which were used to collected aerosol particles. The system has one laser beam which is split into two laser beam, one being information light which transfer through glass pipe, the other being reference light which transfer directly through atmosphere. so the measurement system could well eliminate the effect of all kinds of measurement errors which were caused by optical ullage and circuit noises and power fluction.

本测量系统利用核孔过滤膜采集气溶胶粒子，测量系统的光路由同一光束分为两路光组成，一路为信号光，通过光管传输，另一路为参考光，通过信号光和参考光相比很好地消除了测量系统中由于光管损耗、电路放大倍数的差异及光功率起伏等因素所引入的误差对吸收系数测量的影响。
