Studies were conducted to investigate hosts, life cycle, population dynamics and natural enemies of mulberry scale, Pseudaulacaspis pentagona Ta. & Tozz., from 1987 to 1988 in southern region of Korea. The host plants were 22 families and 74 species. Host plants belonged to genus Prunus in general were severely damaged due to mulberry scale. Mulberry scale was most likely to have three generations a year with first occurrence of larval stage from mid-May to late June, second occurrence from mid-July to mid-August and third occurrence from early September to late October including 3 peaks in early and mid-June, late July and mid-September. In case of each stage occurrence, eggs were peaked on 10th day, larvae on 25th day and adults on 7th day from beginning of occurrence, respectively. Natural enemies were observed as parasitoids of 3 species such as Aphytis diaspidis, Archenomus orientalis and Apterencyrtus mocrophagus and as predators of 3 species such as Chilocorus Kuwanae, Chilocorus rubidus and Hormonia axyridis. Shoot growth was affected by mulberry scale and Lepra to dwindle as much as half of normal growth.

Two pupillarial species, $Cryptoparlatorea$ $leucaspis$ Lindinger and $Fiorinia$ $japonica$ Kuwana, are recorded for the first time in Korea. Both species were found on coniferous trees, $Cryptomeria$ $japonica$ and $Torreya$ $nucifera$. Also an identification key, brief diagnoses, and photographs of Korean pupillarial species are provided to assist in their identification.

The daily rhythm of sex pheromone production and release by females of the black pine base scale, Matsucoccus thunbergianae Miller and Park, was demonstrated by studying the amounts of pheromone possessed and released by females, periodically after emergence. Cycles of both pheromone production and release had daily peaks between 8 a.m. and 2 p.m., and has marked decreases after 4 p.m. It appeared that the amounts of pheromone gradually decreased three days after the emergence. Significance in synchronization of the daily rhythm of female pheromone release and activities of males and females with reference to reproductive success in this species is discussed.

Thirteen species of mealybugs were intercepted in quarantine at Korean ports of entry on plant materials from China over the past 9 years (2000-2009). Of these, Phenacoccus madeirensis Green has been newly reported in China through this study. This list and key are provided to assist in identifying intercepted specimens of mealybugs from China.

The pest species occurring on the aboveground parts of Phalaenopsis orchids were studied for a period of two years (Aug. 2013 to June 2015) at 9 Phalaenopsis farms in Korea. In total, 10 species of insect pest were identified : Tenuipalpus pacificus Baker, Tyrophagus putrescentiae Schrank, Frankliniella occidentalis Pergande, Frankliniella intonsa Trybom, Thrips tabaci Lindeman, Scirtothrips dorsalis Hood, Pseudococcus dendrobiorum Williams, Pseudococcus longispinus Targioni Tozzetti, Coccus hesperidum L., Limax marginatus $M{\ddot{u}}ller$. T. pacificus occurred in most of the farms surveyed in this study (6). The observation frequency of T. pacificus and F. intonsa were highest, they were observed in 10 out of 96 surveys. Although P. longispinus was only observed to occur on two farms, their observation frequency (9 observations, 9.4%) and density (2-289 per 20 plants) were high. Thus, it seems that T. pacificus, F. intonsa, and P. longispinus are the major pests affecting Phalaenopsis orchid farms in Korea.

Two species of Encarsia, Encarsia explorata (Silvestri) from Aulacaspis rosarum Borchsenius, A. yabunikkei Kuwana and Lepidosaphes pinnaeformis ($Bouch\acute{e}$), and Encarsia lutea (Masi) from Bemisia tabaci (Gennadius) are newly documented in the Korean fauna of aphelinids (Hymenoptera: Aphelinidae). Brief diagnostic criteria, photographs, and information on the distribution and hosts of these species are provided. Also a key to species of Encarsia from Korea is given for correct species identification.
