Effects of Υ- ray irradiation on Phenacoccus solenopsis Tinsley
Abstract a multiple Phenacoccus solenopsis Tinsley is an entry quarantine pest in China, which has a wide range hosts and transmitted ways to spread. In order to develop an effective treatment to prevent this mealybug transmit- ted by feeding hosts, the effect of Υ- ray irradiation on the survivor and reproduction of P. solenopsis was tested at range of irradiation doses. The results showed that the survival rate for each instar nymph decreased significantly with the increasing absorbed dose. At the same dose level, the tolerance of individuals to absorbed dose increased with growing life stage. The most tolerant life stage was found to be 3rd instar nymph and adult. At large - scale ir- radiation test, no survival female adult developed from either 3rd instar nymphs or adults irradiated produced off- spring at 130 Gray dose, indicating that the dose of 130Gy or above could be sufficient to prevent the reproduction of this mealybug.
