Studies were conducted to investigate the labour-saving control method of rose powdery mildew(Sphaerotheca pannosa) with sulphur fumigation in korea. The results are abstracted as follows. Sulphur produces SO_2 while burning and causes plant injury. However, if the sulphur is vapourized by solution status without burning, sulphur forms thin films on the surface of leaves or stems of roses. Thus, mycelia and oidia of rose powdery mildew can be controlled by this mechanism. Apparatus is tin cylinder container with 40 cm in diameter by 17 cm in height. The electric wires are installed at 2 cm high from container bottom. Temperature regulator (Keeping temperature 130-60℃) and timer are also installed. Place 2 kg of sulphur powder in container and heat to vapourize sulphur. Sulphur powder should be always over 1/3 to prevent burning. The bioassay apparatus was operated in the closed greenhouse at night for 4-5 hours for 5 days. One fumigation apparatus was enough for 990㎡. The 100% of rose powdery mildew was controlled. Superficial plant injury was not observed on roses at the rate of standard and double amount. One Fumigation apparatus was installed in the 990㎡. The 100% of rose powdery mildew was controlled. Superficial plant injury was not observed on roses at the rate of standard and double amount. One fumigation apparatus was installed in the 990㎡ of greenhouse were roses were cultivating. Observations were made from February to October. Sulphur fumigation method resulted in 99-100% of pest control by four times compared with 50-70% in farmers' routine method by eight times.

A biological study was done on primary parasites and hyperparasites of chrysanthemum aphid, Macrosiphoniella sanborni (Gilltte) (CSA), collected from chrysanthemum field at Chinju and Masan area from April to September 1993. The results of mummification of primary parasites, host selectivity between primary parasites and hyperparasites and ratio of mummification, number of archegonia and longevity of important species were obtained as follows: Five species of Aphidiidae were collected from CSA ; those were Lysiphlebia japonica, Trioxys hokkaidensis Takada, Lysiphlebus ambiguus, Binodoxys nearctaphidius Mackauer and Lysiphlebus salicaphis(Fitch). Among the 908 mummies collected in the field, adult Aphidiidae and adult hyperparasites were 52.6%, and 27.3%, respectively. L. salicaphis, B. nearctaphidius and L. ambiguus were a few of important species attacking CSA and the rate of their occurrences the host were 39.5%, 29.1% and 14.5%, respectively. All the hyperparasites collected from CSA were identified as four species ; those were Eucoila sp., Protaphelinus nikolskajae(Jasnosh), Lygocerus testaceimonus Kieffer and Ardilea convexa(Wallser). Among the collected hyperparasits, Eucoila sp. and P. nikolskajae were dominant species and their occurrence rate was 50.0% and 39.9%, respectively. As a results of analysis on parasite-hyperparasite interrelationship in CSA, The parasites, A. convexa and L. testaceimonus, attacked 4 hyperparasites out 5 and the other paracites attacted almost all of hyperparasites. In the ability of parasitism, Binodoxys nearclaphidius was higher than Lysiphlebus salicaphis. There was no difference between Binodoxys nearctaphidius(190) and Lysiphlebus salicaphis(180) in number of archegonia, but B. nearctaphidius(60.8%) was higher than L. salicaphis(39.2%) in the rate of mummification to archegonia. The longevity of Aphidiidae and hyperparasites was investigated by feeding honey. The results showed that hyperparasites had lived 18.0 to 19.0 days, while Aphidiidae lived only 2 to 3 days.

Susceptibities of Two-spotted Spider Mite (Tetranychus urticae Koch) collected at 5 locations were assessed to 10 acaricides. The response to acaricides were almost similar in female adults and eggs. There were considerable difference in susceptibility depending on the acaricide treated and the region from which the population was collected. The population showing resistance ratio of more than 20 with respect to certain acaricide was regarded as a resistant population to the acaricide. The resistant population in terms of female adult were as follows : Kimhe population to azocyclotin, cyhexatin, and fenbutatin-oxide ; Changweon population to dicofol and fenbutatin-oxide ; Tongyeong population to dicofol ; Chinju population to cyhextin, dicoful and fenbutatin-oxide ; Haman population to cyhextin and azocyclotin. The resistant populations in terms of egg were as follows : Kimhe population to bifenthrin, hexythiazox and tetradifon ; Changweong population to bifenthrin and amitraz : Tongyeong population to dicofol and tetradifon ; Chinju population to amitraz, clofentezine, and bifenthrin ; Hamang population to hexythiazox, dicofol, and bifenthrin. However, the female adults and eggs of all field population were susceptible to abamectin only. This tendency was also reported previously in the susceptible strain from laboratory.

A series of experiments were conducted to evaluate the varietal differences in resistance of Korean new rice cultivars to the white-backed planthopper(WBPH), Sogatella furcifera HORVATH(Ⅲ). The number of rice cultivars tested were twenty-one from the Office of Rural Development (ORD), and eight from the College of Agriculture, Seoul National University(SNU). The nature of their varietal resistance of rice to the WBPH were studied in terms of the seedling reaction, the insect population build-up, and honeydew excretion with feeding activity. (1) Seven cultivars out of the 34 cultivars tested indicated resistant reaction in seedling test; SNU-020713, -1768, -1770, -011063, -01165, -01166, and -01167. (2) The feeding preference of the WBPH adults and nymphs was higher on the susceptible Jinheung than on the test cultivars, and their feeding preference did not steadly coincide with the seedling reaction to the WBPH. (3) The ovipositional preference studies indicated that the insects exhibited distinctly different preference for different cultivars, but their tendency was not steady; for example, the cultivars Milyang-48 and SNU-01701 compared with Jinheung were significantly prefered for oviposition despite showing the susceptible seedling reaction and the cultivar SNU-01702 was significantly less prefered for oviposition than Jinheung,even though they were all susceptible in seedling reaction. (4) The population build-up of WBPH was smaller on the resistant cultivars (R-check) than the susceptible ones. (5) Post-embryonic developmental period was relatively shorter on the susceptible cultivars, but it was not always true. (6) The adult emergence rate was relatively higher on the susceptible rice cultivars than those on the resistant and moderate ones. (7) Differences in sex ratio of the WBPH on the susceptible and resistant cultivars could not be made sure due to the small number of adults tested. (8) The amount of honey-dew excreted was measured using the ninhydrin staining method. The small amount of honeydew was recorded with the test cultivars to the WBPH. In conclusion, the nature of varietal resistance of rice to the WBPH was considered to be related with the nymphal survival,develpmental period of nymphs and feeding activity.
