説明

The influence of temperature on the development of two housefly populations, organophosphorus insecticide-resistant Hokko colony and susceptible Takatsuki strain, was studied in the present experiments, using two kinds of culture medium with different initial water content (approximately 33 and 50% respectively). Two hundreds larvae were reared in one container receiving 150g of medium, and two or three containers were used in each experiment. The viability of Hokko colony was more than 90% at 20°-35℃ and a little lower at 15℃, but its mortality was very high at 40℃. Takatsuki strain showed the same tendency as Hokko colony except that viability was approximately 60% at 35℃ (Takatsuki was not reared at 15℃). The relation between mean medium temperature (t) and rate of development (ν) in Hokko colony could be expressed in, ν=0.0082t-0.0810,for egg-larval period, ν=0.0120t-0.1376,for pupal period, and ν=0.0049t-0.0522,for egg-pupal period. And Takatsuki strain showed the same tendency at 20°-35℃. The developmental zeros and thermal constants calculated from these equations were 9.9℃ and 122 day-degrees in egg-larval stage, 11.5℃ and 83 day-degrees in pupal stage, and 10.7℃ and 203 day-degrees in egg-pupal stage, respectively. The results in egg-pupal stage were compared with those obtained by other investigators and found to be suitable to them at temperatures below 30℃. The body weight of pupae was lighter when larvae were reared at higher temperature or in culture medium of lower initial water content. And pupae of Hokko colony were heavier than those of Takatsuki strain at 35℃. By comparing the present results to those of others, it is considered that the suitable temperature range for development of the housefly lies between 17°-35℃, and developmental zero and critical high temperature are approximately 10° and 40℃, respectively. The reason for lightening effect of lower initial water content on the body weight of pupae is considered that available food quantity was smaller at lower water content, where the greater part of medium was dried more quickly. In comparison between two populations, there were no distinct differences in duration of development. It may be, however, concluded that, Takatsuki strain, at least the present sub-strain, in immature stage is inferior in the adaptability to higher temperature of 35℃, for it shows lower viability and the body weight of its pupae is lighter than Hokko colony.
