  • Increase in world trade commodities along with climate change entails frequent pest insect invasions from subtropical to temperate zones. Tephritidae is one of two families in fruit flies along with Drosophilidae and consists of more than 5,000 species. Some tephritid flies in genera Anastrepha, Rhagoletis, Ceratitis, and Bactrocera are highly invasive and give serious economic damages on fruits and vegetables in temperate zones. This review focuses mainly on Bactrocera fruit flies, which have been well studied in control techniques to defend their invasion and colonization. Though various control techniques against Bactrocera fruit flies have been developed, less efforts have been paid to establish efficient integrated pest management (IPM) programs. This review introduces current control techniques of fruit flies and some successful IPM programs implemented in subtropical islands. In addition, major fruit flies infesting crops in Korea have been also reviewed in their occurrence and control programs.

  • The concept of integrated pest management (IPM) first developed in the 1950s, and the concept of economic control via pest management was established in the 1960s. Research on IPM began in the United States and Europe, and IPM studies in Korea started with citrus insects and paddy field pests following the distribution of high-yield varieties of rice. Apple IPM in Korea began with research on pest control using chemical pesticides and pesticides resistant to insect pests, studies on the ecology of insect pests and their natural enemies, and the exploitation of sex pheromones on insect pests. Since the 1990s, IPM research and field projects have been carried out simultaneously for farming households. In the 2000s, the development of pest monitoring and forecasting models centered on mating disturbances, database programs for pests, and networks for sharing information. IPM technology has expanded via the development of unmanned forecasting systems and automation technologies in the 2010s.

  • Integrated mite management provided a basic direction to early the fruit tree IPM. The early IPM concept was based on incorporation of the biological control for mite pests with the existing chemical control compatibly. Since then, the hypotheses and mechanisms of the interaction between species diversity and pest population dynamics have provided a broader understanding of mite-centered pest management in fruit tree ecosystems. Based on the principle of the ecosystem, biological control and pest management through habitat modification or manipulation are developing to the concept of agro-ecological engineering. In particular, the natural enemy diversity is dynamically changed according to the different cultivation environment in the management of mite pests, and the species composition of phytophagous mites is also changed by the environment for orchard management. This paper reviews the biological control of mites, which was the basis of apple IPM, and also re-examines the topics of species diversity and pest management, predacious mite diversity in relation to mite control and the change of species composition of mite pests in the sight of ecological engineering. Finally, we suggest a strategy for biological control of spider mites in apple orchards in Korea.

  • Susceptibility of the predatory mite, Phytoseiulus persimilis to 8 insecticides was evaluated. In treatments with insecticides tested, 78-92% of adult female predators survived after 168 hrs after treatment. Adult female predators treated with insecticides tested produced 62.6-93.4% as many eggs as did control females and eclosion of eggs deposited by treated predators was not affected. Moreover, hatch percentage of P. persimilis eggs and survival of nymphs were not seriously affected by exposure to the insecticides tested. Immatures of P. persimilis survived on the leaf disc treated with insecticides tested and 98-100% of immature predators reached adulthood. Based on the results, insecticides tested are expected to be promising candidates for use in integrated pest management program with P. persimilis.

  • It is an important research area in Integrated Pest Management System to estimate the pest density within plants, because the artificial controls such as spraying pesticides or biological enemies depend on the information of pest density. This paper studies the population density distribution of two-spotted spider mite in glasshouse roses. As the data were collected repeatedly on the same subject, Subject-Specific and Population Averaged approaches are used and compared.

  • Early, mid, and late maturing soybean varieties were artificially infested with larvae of Delia platura at seeding, and then later development and productivity of soybeans were studied. In addition, in hope to utilize as possible tactics in the management of D. platura in soybeans, cultural factors such as contents of organic matter in soil, soil types, and the use of plastic mulching on the degree of damage to soybean plants by D. platura were examined. Primary leaf damage by the larva delayed the forthcoming vegetative growth but not the blooming which is initiated by the change in day length. Degree of delay in growth was more severe where leaf damage was induced by insect infestation than where artificially excised, apparently owing to simultaneous damage in stems and roots besides primary leaves. Productivity of soybeans also dropped significantly in plants with 25 % or more loss in the primary leaf area by the larva. Both transparent and black plastic mulchings shortened the period from seeding to emergence of soybean thus reducing the chance of possible attack by the larva. Soybean seedlings grown in clay loam or clay were attacked less by the larva than those in other types of soil. High organic matter content in the soil enhanced speed of emergence resulting in less larval damage to the seedling.

  • 파프리카(Paprika)는 착색단고추로 1995년부터 본격적으로 재배, 수출용으로 소비되었으나 최근에는 피자, 샐러드용으로 국내소비도 많아지고 있다. 재배양식은 여름형과 겨울형이 있다. 여름재배는 3월 중순경 정식, 6월 중순부터 12월까지 수확한다. 겨울재배는 9월 초순정식, 12월 초부터 7월까지 수확하여 연중 재배되고 있다. 시설 내 파프리카 생육적온은 주간 $21-27^{\circ}C$, 야간 $18-19^{\circ}C$이며 습도는 70-80%로서 시설내 발생하는 미소해충들이 번성하기에 좋은 조건이다. 해충 방제는 피해를 정확히 진단하고 발생초기에 적절한 방제수단을 강구하여야 피해를 최소화 할 수 있다. 따라서 재배유형별로 작기 전 기간에 걸쳐 종합적인 해충관리대책이 수립되어야 하며, 어린모 구입시 건전묘 구입, 해충 수시 예찰과 조기방제, 작기 후 포장위생을 철저히 하여야 한다.
