Gamma irradiation is a potential phytosanitary treatment to control the mealybug Planococcus lilacinus. P. lilacinus is a polyphagous mealybug that attacks fruits with high economic value and becomes a quarantine pest that hinders fruit exports to foreign countries. Efficacy test was carried out on P lilacinus 1st instar nymphs and adults. The radiation doses used were 0, 50, 75, 100, 150 and 300 Gy for 1st instar nymphs and 0, 400, 800, 1,200, 1,600 and 2,000 Gy for adults. Observations were made on the mortality of mealybugs every day. In addition to mortality, the sterility of adults and eggs was also observed. The lethal dose was analyzed by probit and expressed in terms of LD50, LD95 and LD99. The results showed that 1st instar nymphs were more susceptible, and adult mealybugs were most susceptible to irradiation. The adult LD99 is 3,032.9 Gy. This study is expected to contribute to the phytosanitary treatment of mealybug pests on fruits. [ABSTRACT FROM AUTHOR] |
