説明
The insecticide treatment period for the effective control of the Japanese wax scale, Ceroplastes japonicus GREEN was examined. The authors conducted observations on the seasonal occurrences of crowlers, their age distribution, successional changes, and the growth rates of the different larval stages and also examined the controlling effect possessed by two kinds of insecticides upon some of the developmental stages of this scale insect. The crowlers occured most abundantly in June. Its peak occurrence was found to be in the middle and late June. The growth rates of the larval stages were observed to be as follows: 1st instar ranged from 20∼34 days, 2nd instar ranged from 30∼40 days and the 3rd instar ranged from 40∼54 days. Two kinds of insecticides viz. Imidan and Fussol were treated upon 6 developmental stages, from late 1st instar stage to late 3rd instar larvae. As results, it was observed that Imidan was effective in the beginning of 2nd instar and Fussol was most effective from the late 2nd instar. From the results of this experiment it is concluded that an adequate time for control by Imidan was 25∼30 days after the first emergence of crowlers, and by Fussol about 50 days after the first emergence of crowlers.
