TEMPERATURE-DEPENDENT DEVELOPMENT OF THE CYCAD AULACASPIS SCALE, AULACASPIS YASUMATSUI(HEMIPTERA: DIASPIDIDAE).

The article reports on the study which examines the temperature-dependent development of cycad aulacaspis scale, Aulacaspis yasumatsui Takagi (hemiptera). The study notes that the lowest temperature which ranges from 8 to 12 degrees celcius and 538 degree-days are needed for female immature development in a linear model. The development rates of the scale of cycad aulacaspis scale, Aulacaspis yasumatsui Takagi and their natural enemies including Rhyzobius lophanthae are also presented.
